IE 6 XONE:464 User Guide Welcome to the XONE:464 The Allen & Heath XONE:464 presents a unique concept in combining a professional live sound mixer with a serious DJ performance tool in a dedicated club format. And, above all, it features sound quality second to none. XONE:464 has been designed and constructed using the same rigorous standards we apply to our large format professional consoles used and respected by top engineers throughout the world. We have had great fun designing this new range. We are sure you will get even more enjoyment using it. MONO Inputs The 4 mic/line inputs are ideal for live performances, or for your MC, DJ and presenter microphones. An extensive Aux system lets you provide artists with individual stage monitors, helping them to give their best performance. It can also feed multiple effects processors such as reverb and delay. A 4 band EQ with swept frequency mids is the same as that found on top end professional consoles, and helps you deal with source problems, enhance clarity or sweeten the live mix. Insert jacks let you patch in channel processors such as compressors to help control the dynamic range of individual microphones. Smooth 100mm faders with 10dB available boost provide fine precision for live mixing. Direct outputs are provided for recording, spot effects or channel linking. STEREO Inputs The 6 dual stereo channels allow selection of up to 12 stereo sources including 4 RIAA turntables. The 4 band performance EQ gives you a unique extra band for solid bass control. Boost restricted to 6dB prevents system overload while an extended cut of up to a massive 26dB provides complete sound sculpturing. Full routing lets you assign any channel direct to the main mix or through either X or Y crossfader channels. Large illuminated Cue switches and signal meters keep you in control of your sources. The Aux system is tucked out of the way of the performance controls and provides 2 mono and 2 stereo feeds for monitors, effects, recording or additional zones. EXT Input Provides an additional stereo input to Mix1, Mix2 or both, ideal for stage reverb returns or sub inputs. Or it can be configured as an external monitor source. VCA Crossfader Uses a DC voltage to control the audio meaning no clicks, bangs or crackles as the fader wears. The crossfade curve can be set for either 6dB dip in the middle, ideal for seamless beat mixing, or for constant level, better suited to scratch mixing. The fader is removable from the front panel for quick replacement. Crossfader output can be fed to the Aux system which means that you can provide zone and effects feeds from your mix. A Pan control provides yet more performance effect. VCF Filters Unique to XONE, two stereo state variable Voltage Controlled Filters provide the DJ with a new tool for live performance creativity. These are very similar to those found on classic analogue synths but benefit from modern, quiet and stable technology. Use these to sweep the sound by accentuating or cutting frequencies from 100Hz to 20kHz. The 3 filter types HPF, BPF and LPF can be combined to create many more amazing effects. A large Resonance control changes the `Q' or sharpness of the filter effect from subtle to extreme. Each VCF has its own in/out switch to toggle the effect on or off. MIX Outputs Mix1 and Mix2 are two independent stereo mixes on balanced XLR and with inserts for patching in limiters and other processors. Use Mix1 for music only and Mix2 for music + mics, or use them as completely different mixes, ideal when you want to create separate stage and DJ mixes feeding independent rigs. Both include additional stereo outputs suitable for recording your mix. A twin connector Mono output sums the L and R signals from either Mix1 or Mix2 to provide additional mono zone and/or lighting controller feeds. MONITOR Section Extensive monitoring is provided so that you can keep a check on every input and output signal to prevent overload and to cue your mix. A stereo meter always shows Mix1 output level, another the selected monitor or cue source. An 8 way switch bank selects which output to monitor, and is automatically overridden by any Cue pressed. Two pairs of headphones can be plugged in. Split-CUE allows accurate track matching. An independent stereo Booth Monitor feed includes Cue enable, Mono sum and Mute functions to satisfy all your monitoring needs.

However, we provide these notes so that you can plug up and experiment with sounds from your XONE:464 immediately if you prefer to read the full guide later. Please note that you should first read and understand the Important Safety Instructions printed at the beginning of this guide. This simple procedure requires a microphone, CD player and headphones. Alternatively you can connect a pair of turntables and start mixing right away. Please read the rest of this guide before connecting to your amplifier and speaker systems. Set all controls to their starting condition. Set all FADERS, GAIN, AUX, EXT IN, VCF, RESONANCE, PHONES and MONITOR controls minimum. Set all PAN and EQ controls to their detented centre position. Set all switches to their up position. Plug in a microphone. Plug a microphone into CH1 XLR input using a high grade balanced mic cable. We recommend you use a professional standard low impedance balanced dynamic microphone, such as used for live performance vocals. Do not use inferior high impedance or unbalanced microphones as these can degrade the sound. Plug in a CD player. This provides a good stereo audio source as a starting point. Plug into CH5 Input B. Do not use Input A as this is intended for turntables with magnetic cartridges requiring RIAA equalisation. Plug in the headphones. You can plug into either the top panel or the rear panel socket. Two pairs can be plugged in at the same time. Use the best headphones you can afford for your application. We recommend the professional grade closed-ear type of 30 to 600ohms impedance, and with ¼" TRS jack plug. Avoid using the popular mini jack to ¼" adapters as these can quickly prove unreliable. Connect AC mains power. Check first that the correct mains lead with sealed plug suitable for your local supply has been provided with your console. Plug into the IEC AC MAINS IN socket and switch mains on. Switch the console on. Press the rear panel ON/OFF switch. Check that the green POWER ON led at the top of the panel lights. You may notice that the console meters flash briefly. This is normal during power up. Always switch connected amplifiers on last and off first to avoid power on/off thumps. Select the stereo source. Start with the CH5 CD source. Press the PHONO/LINE switch to select Input B. The led should glow red when you select Input B, green for Input A. Adjust the channel gain. Start the CD player. Adjust CH5 GAIN control until the average music level lights the green 0 led with loudest peaks lighting the yellow +6 led. Reduce GAIN if the red PEAK! Led lights. If no signal is present check that the music source is playing and the correct input is selected. MIC CD PLAYER HEADPHONES IN B AC MAINS SUPPLY VO LTAG R E E ANG : AC MAINS IN ~ 100 - 240V ~ 47-63Hz ~ 30WMAX O FF O N 10 XONE:464 User Guide Check the sound using the Cue system. With the music playing press the large CUE switch. The switch itself and the master section CUE led light to show that the cue monitor is active. The channel signal is now sent to the headphones. Slowly turn up the headphones level control until you hear the music at comfortable volume. Avoid listening to loud headphones levels for long periods as this may damage your hearing. The channel signal is now displayed on the main monitor meters giving you finer control in setting the gain. Note that the cue system lets you monitor channel signals prefader. In other words you can check or cue any source before you raise its fader to bring it into the mix. Route the signal to the main Mix1 output. Release the CUE switch. The CUE led turns off and the headphones and monitor meters go quiet. Raise CH5 fader to its top `0' position. Raise MIX1 master level to maximum. With the XFADE ON switch in its up position the signal is routed direct to Mix1. The signal is now indicated on the Mix1 meters at the same level as the channel meter. The level is now the same throughout the console signal path, as set by the channel gain control. This is the ideal setting with meters averaging 0dB so giving the best signal-to-noise performance while maintaining plenty of headroom to avoid clipping. Listen to the main Mix1 output. To hear the signal in the headphones press the MIX1 monitor select switch. Make sure the other select switches are up as these will automatically override Mix1 if pressed. Similarly any CUE switch pressed will override the monitor selection. Check the effect of the Stereo EQ. Press CH5 EQ ON switch. This lights to show that the signal is routed through the equaliser. Now try the effect of each of the 4 frequency bands. The EQ is designed for creative live performance control and provides a safe +6dB boost and a massive ­26dB cut. Experiment with cutting rather than boosting frequencies to create dramatic effects. These can be punched in or out using the EQ ON switch. Route through the Crossfader. Press XFADE ON to route the signal through the crossfader rather than direct to Mix1. The green X led lights indicating that the channel is assigned to the left (X) side of the crossfader. Press the XY switch to assign the signal to the right (Y) side. In this case the yellow Y led lights. Note the green X and yellow Y leds above the crossfader to help you see which channel is routed to which side. Using the Crossfader. This lets you fade between signals routed to either side, typically to fade smoothly into a new music track or to creatively layer sounds when scratch or beat mixing. Experiment further by connecting two music sources such as CD or turntables and assigning one to X, the other to Y. Use XFADE PAN to adjust the balance between the left and right signals of the active source, either to correct an imbalance or as an effect in its own right. XONE:464 User Guide 11 Adding VCF filter effects. Each side of the crossfader includes a stereo Voltage Controlled Filter which presents the DJ with a unique set of live performance tools to create subtle or startling tonal effects. With the signal assigned to the Y side of the crossfader, and the crossfader moved fully to the right, the music is routed to Mix1 and should be heard on the headphones. Press the Y FILTER ON switch to route the signal through the analogue filter section. The blue led lights to show that the filter is active. Check that the large LPF switch is illuminated indicating that the power up default lo-pass filter type is active. The sound should change to a rumbling bass line with higher frequencies removed. Sweep the filter frequency. Turn the VCF control clockwise and you should progressively hear higher audio frequencies returning to the mix. This control sweeps the effect from low to high frequency. Adjust the filter resonance. Slowly turn the RESONANCE control clockwise as you sweep the frequency and you should hear the `Q' or `sharpness' of the effect changing from subtle to drastic as the roll-off knee sharpens and frequency boost is added. Increasing resonance boosts a narrow band of selected frequencies. Make sure you reduce the channel gain if the red peak meters start to flash. Change the filter type. Press one or any combination of the large HPF, BPF and LPF filter type switches to experiment with different performance effects. For example pressing HPF and LPF together produces a notch effect. Once you are familiar with the creative power of these filters you can apply them to your performance. More information is available later. Experiment with the microphone source. Finish off by trying a microphone channel. Stop the CD and pull CH5 fader down. Next, press CH1 CUE and talk into the mic. Gradually increase the mic GAIN control until the monitor meters read an average 0dB for normal vocal level. You should also hear yourself through the headphones. Check the effect of the 100Hz lo-cut filter. Press this switch to remove low frequencies below 100Hz. It is standard practice to switch this in when working with vocal mics as this effectively removes the proximity `popping' effect when close miking. Check the effect of the mic EQ. Experiment with the EQ to learn what effect these controls have on the sound. Unlike the stereo channel EQ, this is intended for `corrective' equalisation such as smoothing out poor mic response, brightening up the sound to make it more intelligible, or dealing with problem feedback frequencies. It is not usual to use this EQ as a live effect as you would the stereo channel. It is good practice to start with the controls flat and use only as much EQ as is really needed, cutting rather than boosting frequencies.

R UE Earthing The connection to earth (ground) in an audio system is important for two reasons: 1. 2. SAFETY - To protect the operator from high voltage shock, and AUDIO PERFORMANCE - To minimise the effect of earth (ground) loops which result in audible hum and buzz, and to shield the audio signals from interference. For safety it is important that all equipment earths are connected to mains earth so that exposed metal parts are prevented from carrying high voltage which can injure or even kill the operator. It is recommended that the sound engineer check the continuity of the safety earth from all points in the system including microphone bodies, turntable chassis, guitar strings, connector cases, equipment panels and so on. The same earth is also used to shield audio cables from external interference such as the hum fields associated with power transformers, lighting dimmer buzz, and computer radiation. Problems arise when the signal sees more than one path to mains earth. An `earth loop' (ground loop) results causing current to flow between the different earth paths. This condition is usually detected as a mains frequency audible hum or buzz. To ensure safe and trouble-free operation we recommend the following: · Have your mains system checked by a qualified electrician. If the supply earthing is solid to start with you are less likely to experience problems. · Do not remove the earth connection from the console mains plug. The console chassis is connected to mains earth through the power cable to ensure your safety. Audio 0V is connected to the console chassis internally. If problems are encountered with earth loops operate the audio `ground lift' switches on connected equipment accordingly, or disconnect the cable screens at one end, usually at the destination. · Make sure that turntables are correctly earthed. A chassis earth terminal is provided on the console rear panel to connect to turntable earth straps. · Use low impedance sources such as microphones and line level equipment rated at 200 ohms or less to reduce susceptibility to interference. The console outputs are designed to operate at very low impedance to minimise interference problems. · Use balanced connections where possible as these provide further immunity by cancelling out interference that may be picked up on long cable runs. To connect an unbalanced source to a balanced console input, link the cold input (XLR pin 3 or jack ring) to 0V earth (XLR pin 1 or jack sleeve) at the console. To connect a balanced XLR output to unbalanced equipment, link the cold output to 0V earth at the console. · Use good quality cables and connectors and check for correct wiring and reliable solder joints. Allow sufficient cable loop to prevent damage through stretching. · If you are not sure ... Contact your service or local Allen & Heath agent for advice. 14 XONE:464 User Guide Plugging Up The System The XONE:464 uses professional grade 3 pin XLR, 1/4" TRS jack and RCA PHONO sockets. To ensure best performance, we recommend that you use high quality audio cables and connectors, and take time to check for reliable and accurate cable assembly. It is well known that most audio system failures are due to faulty interconnecting leads. The following mating plugs may be used to connect audio signals to the console: All input and output XLR connectors are 3 wire differentially balanced. These have 3 connector pins: Pin 1 = ground (screen), Pin 2 = signal hot (+), Pin 3 = signal cold (-). All the jack sockets are the 3 pole TRS type. These are wired to work with both the balanced TRS or the unbalanced 2 pole TS type plugs. The sockets have 3 connector pins: Inputs and outputs are Tip = signal hot (+), Ring = signal cold (-), Sleeve = ground (screen). Insert connections are Tip = send, Ring = return, Sleeve = ground. The RCA phono connectors are the 2 wire unbalanced type typical of those found on equipment such as CD players, turntables and domestic amplifiers. Avoid reversing + and - on balanced connections as this will result in out of phase signals (reverse polarity) which may cause signal cancellation effects. For live work where long cables runs are required, balanced interconnections should be used. However, interconnections between more affordable 2-wire (signal, ground) unbalanced equipment and the console are unlikely to cause problems if the cables are kept short. Refer to the following diagram for unbalanced to balanced connections. Dealing with Ground Loops, Buzz and Interference For optimum performance all audio signals should be referenced to a solid, noise-free ground (earth) point, frequently referred to as the `star point' or `clean earth'. A ground loop is created when the signal has more than one path to ground. Should you experience hum or buzz caused by ground loops, check first that each piece of equipment has its own separate path to ground. If so, operate ground lift switches on connected equipment in accordance with the instruction manuals. Alternatively disconnect the cable screen at the destination end only. This breaks the offending loop while still maintaining the screening down the length of the cable. WARNING For your safety do not remove the earth (ground) connection in the power lead of the console or connected equipment. To avoid interference pickup keep audio cables away from mains power units and cables, thyristor dimmer units or computer equipment. Where this cannot be avoided, cross the cables at right angles to minimise interference. XONE:464 User Guide 15 Connecting the Mono Channel 4 INSERT IN 4 DIR OUT 4 MIC 4 + 48V INPUT The input provides both an XLR and a TRS jack connector. The XLR is normalled through the jack connector. This means that plugging in a jack overrides the XLR source. Plug a microphone into the XLR socket leaving the jack unplugged. Plug a line level source into the jack socket and select the front panel PAD switch. For line level sources on XLR plug into the XLR leaving the jack unplugged and select PAD. This feature lets you connect a wide 70dB range of mic or line sources on either XLR or jack. Both XLR and jack inputs are 3 wire balanced. This prevents interference pickup on long cable runs when connecting to balanced sources such as microphones. To connect an unbalanced XLR source link Pin 3 to Pin 1 in the XLR plug. The jack input automatically grounds the cold (-) input to accept unbalanced TS (mono) jack sources. To connect an unbalanced source using a TRS (stereo) jack you should link ring to sleeve in the plug as shown above. Do not select +48V phantom power when connecting unbalanced sources. MIC +48V Press this tamperproof underpanel switch when connecting to microphones such as condenser types which require phantom power. This provides +48V DC to pins 2 and 3 of the XLR. WARNING Do not connect unbalanced sources or cables to the XLR inputs when phantom power is selected. Use +48V only with balanced microphones which require powering. Note that harm will not be done to non powered microphones as long as they are balanced. To avoid loud clicks always turn the channel off by releasing the ON switch when switching +48V on or off and when plugging or unplugging microphones with power applied. INSERT You do not need to plug anything into the insert socket for normal operation. It is a break point that lets you plug in an external signal processor such as a compressor or noise gate if required. Plugging in a jack breaks the signal path after the input pre-amp and before the EQ. The signal is unbalanced and operates at a nominal 0dBu line level. Use a TRS jack wired as shown above to connect the SEND to the processor input and the RETURN from the processor output. The sleeve provides the common ground for cable screening. Use a TRS Y-adapter and two standard jack leads or wire two leads to a TRS plug. If required you can tap off the send to provide an alternative pre-EQ direct output by plugging in a lead with tip and ring shorted together so that the channel signal path is not interrupted. DIR OUT This provides a post-fader direct output for connection to external processing or recording equipment. This can be set to pre-fader by changing an internal link option. The output operates at 0dBu and is impedance balanced on TRS jack to provide the benefit of interference rejection when connecting to equipment with balanced inputs. You can also connect to unbalanced equipment as shown above. 16 XONE:464 User Guide Connecting the Stereo Channel 10 IN RIAA INA L 9 A L R R INB L INB L/M R R INPUT A This provides a pair of RCA phono sockets for connection to stereo sources.

L,R XLR OUTPUTS The Mix1 and Mix2 main left and right outputs are on balanced XLR connectors. 3 Pin female XLR plugs are required to connect to these. Connect to balanced equipment for maximum interference rejection on long cable runs. To connect to unbalanced equipment link Pin 3 to Pin 1 in the XLR plug as shown. Alternatively use the unbalanced RCA phono outputs. Signal level is a nominal +4dBu (0 on the meters). These outputs typically feed the main amplifier/speaker systems or stereo DJ to large FOH console. Mix1 can feed Mix2 by pressing a tamperproof front panel switch. Typically this could provide a music only zone or clean feed. L,R RCA OUTPUTS These are intended for connection to recorders but can be used as additional zone feeds, or as an alternative to the XLR outputs, for example when connecting to domestic hi-fi amplifiers. M XLR OUTPUT This provides a sum of the post-fader left and right signals. Use the rear panel switch to select either Mix1 or Mix2 as the source. The output is balanced XLR operating at a nominal +4dBu. Connect to balanced or unbalanced equipment as described above for the L R outputs. Typical uses include feeding mono speaker, submix, centre fill, sub bass, mono zone, sound to light and recording systems.

Independent control is provided for the local and the headphones monitor systems. This output typically feeds the DJ booth monitor with the music only mix, and Cue if required. HEADPHONES 2 OUTPUT Two outputs are available for stereo headphones, one on the front panel, the other on the rear panel. This is convenient for permanent installation or when two headphones are required at the same time, for example presenter and guest in a broadcast application. The same signal is available from both. Headphones are available in many different styles, impedances and volume ratings. To get the best from your system we recommend that you use high quality closed ear headphones in the range 30 to 600 ohms. 8 Ohm headphones are not recommended. WARNING Some headphones are more sensitive than others and can produce higher output levels. To avoid damage to your hearing start with the PHONES level control at minimum and turn up only as much as is needed to maintain comfortable listening level. Do not drive headphones at high listening levels for long periods of time. User Connector Options SYS-LINK OUT (option)
