It is an echo of the earliest days of pro audio when pioneering individuals hand crafted outstanding products free from the constraints of cost and time. We revisited the basics of audio circuit design restoring the simple purity of a minimum signal path meticulously constructed from the finest discrete components. The result is a console that gives great recordings the space and freedom to express their true warmth and clarity. The main circuits use carefully selected transistors instead of ICs to ensure the shortest signal path and high voltage rail operation for massive headroom. The lower open loop stage gain means minimum negative feedback resulting in reduced intermodulation distortion of the complex waveforms typical of music. The all important RIAA input stage uses paralleled audio grade JFETS and a composite passive equalisation network which maintains low noise and very high input impedance constant with frequency. Similar care has been taken with the input preamps using JFETS in a classic long tailed pair configuration and a Class A mosfet output stage which replaces the busy integrated op-amp typically found in modern preamps. Two of the channels feature valve inputs producing the distinctive second harmonic distortion which helps warm up clinical sounding sources such as CD. As much time has been spent carrying out `golden ear' listening tests as performance logging in the laboratory. The result is the simple assurance that you will hear every nuance of the music you mix. The same attention to quality detail is applied to the construction. The face plate is machined from 6mm thick bead blasted aluminium. The main VU meters are a very rugged and accurate original 1950's British telecom design. The vintage durability is also reflected in the choice of the knobs and switches. The XONE:V6 also features the best in modern technology and engineering excellence. The top of the range, oil damped rotary faders are made by Penny & Giles, a British company renowned for its fader expertise. Not only are the controls guaranteed to give you the finest mix precision, they will also give you the longest term service. The power unit also benefits from the finest in linear design for a rock solid bottom end and utmost clarity. The 6 input channels each have two selectable stereo inputs. CH1-4 include selectable RIAA and line inputs. CH5 and 6 feature stereo line valve preamps. Rear panel inserts are provided for patching in external processing. The channel hi-pass filters use large rotary controls for performance mixing. The microphone channel has a balanced XLR input with selectable phantom power, vocal optimised EQ, insert point, on/off switch, and the ability to route to the booth if required. Balanced XLR master and booth stereo outputs are provided. The master output is also available on unbalanced TRS jack, and includes an insert point. The recording output is taken from the booth mix. Two band EQ is available on both the master and booth outputs. The cue system feeds both front and rear headphones sockets. The channel cue switches auto-cancel for fast action, and the cue/mix rotary fader lets you audition how a source will sound when added to the mix. The tone control helps you lift the sounds you want to check in your headphones. Various internal jumpers are provided so you can set preferred source selection and operating levels. We hope you enjoy using the XONE:V6 as much as we have enjoyed designing it. Andy Rigby-Jones, the designer XONE:V6 User Guide 7 INPUT 4 PHONO LINE Channel Controls 6 Input channels are provided. Each has switchable inputs for two stereo sources. CH1-4 provide line and phono (RIAA) inputs. CH5 and 6 feature valve preamps and have two switchable line sources each. All channels provide insert points for patching in additional equipment. Internal jumper options let you change the gain settings and switch out the RIAA equalisation. 18 10 6303 6 10 LEVEL 100 60 200 400 Phono / Line select CH1-4 This toggle switch selects the PHONO input in its left position, or the LINE input in its right position. Line A / Line B select CH5,6 This toggle switch selects the LINE A input in its left position, or the LINE B input in its right position. RIAA The PHONO input passes through an RIAA equaliser. This compensates for the response of the turntable pickup cartridge and results in the desired flat frequency response. Note that the RIAA equaliser can be bypassed using internal option jumpers if you want to use the inputs for additional line sources instead. 40 500 30Hz 600Hz HI-PASS OFF ON Valve preamps 5 CUE 4 3 2 1 0 10 CHANNEL 4 9 6 7 8 The CH5 and CH6 preamps provide the warm, musical sound associated with the characteristically strong second harmonic distortion associated with the valve circuit. Meter This has 8 LEDs which display the level from -18dB to +10dB relative to the normal 0dB operating level. It is peak responding so that it can accurately display fast music peaks. The stereo L and R signals are summed to feed the meter display. Turn back the LEVEL control if the red `+10' LED lights. Although there is still plenty of headroom above this level, it is important to prevent very high channel levels which could overload the mix if several sources are being mixed together. 8 XONE:V6 User Guide INPUT 5 LINE A LINE B Level 18 10 6303 6 10 Adjusts the input sensitivity from fully off to its maximum +10dB gain. Correct use of this control makes it impossible to overload the input preamp. Adjust it so that the meter averages around `0' with loudest peaks up to `+6'. Note that there are internal option jumpers to reduce the maximum gain available to +6 or 0dB. A variable frequency 12dB per octave filter can be switched in or out of the channel signal path using the ON/OFF switch. The cut off frequency can be swept from 30Hz to 600Hz. The large rotary provides fine control during performance. Hi-Pass filter LEVEL 100 60 200 400 Cue 500 40 Press this button to route the channel signal to the headphones. The integral blue LED lights when it is active. An `intelligent' cue system is provided for quick and easy channel monitoring during performance. The cue switches are cleared when the console is powered on. The following is possible: Latching action - Press once to turn it on, press again to turn it off. Momentary action - Press and hold for longer than 2 seconds. Cue turns off when you release your finger. Interlocking action - Press one to turn the previous selection off. This way you can quickly switch from one to another channel. 30Hz 600Hz HI-PASS OFF ON CUE 4 3 2 1 0 10 CHANNEL 5 9 5 6 7 8 Adding action - Press two or more at the same time. Rotary Fader Each channel has a large rotary fader for precision control of its level when mixing. This type of control provides far greater accuracy than the typical linear fader found in most DJ mixers. It uses the renowned Penny & Giles oil-damped potentiometer for smooth movement, accurate control and long life. The rotary ranges from fully off when anti-clockwise to fully on at unity gain (0dB) when clockwise. For best performance operate these controls near to their fully clockwise position for normal music level. XONE:V6 User Guide 9 Microphone Controls A DJ microphone can be plugged in. A professional quality balanced dynamic vocal type is recommended. Phantom power can be internally enabled if a condenser type is preferred. The mic can be switched into the master mix, booth mix, and routes to the cue monitor. An insert is available for patching in processors such as a limiter or compressor. 2.5kHz -15 +15 Mic on/off Switch the microphone into the master mix using the ON/OFF toggle switch. Depending on the position of the rear panel MIC TO BOOTH switch, the signal may also appear in the booth mix. When the mic is switched off, its post fade signal is automatically sent to the cue mix for monitoring. Mic level Controls the level of the microphone from fully off to a maximum +60dB gain. Typical operation with a dynamic vocal mic is around the 2 to 3 o'clock position. A hi-pass filter is built in to help remove handling noise and the popping associated with the close mic proximity effect. 120Hz -15 4 3 2 1 0 OFF ON +15 5 6 7 8 9 Hi-pass filter Mic EQ Two controls adjust the frequency response of the mic channel. 2.5kHz is a shelving HF control, 120Hz is a shelving LF control. Both provide up to 15dB cut or boost. The response is flat at the centre positions. Where possible use only small amounts of EQ, and cut rather than boost. A small amount of HF boost can improve the intelligibility of vocals over the mix, adding brightness. Use HF cut to remove harshness. A little LF boost can add punch to the male voice. Use LF cut to reduce boominess and LF noise. MIC 10 Phantom power An internal option jumper is provided to enable +30V phantom power to the mic input XLR. Only use this if it is required, for example with certain condenser mics. Do not use it with unbalanced connections. 10 XONE:V6 User Guide LEFT MIX LEVEL Master Controls The Master is the main output that feeds the house sound system. An overall level control together with 2-band equaliser is provided. External processing equipment such as a limiter or house EQ can be inserted into the master mix signal path. Main meter Two lamp-illuminated moving coil VU meters display the left and right signals. The needle movement accurately follows the VU (volume unit) standard. It displays the average signal level. The meter is post master EQ and pre MASTER level control so that you can keep a check on the console mix level regardless of house volume. Refer to the notes on Operating Level and meters later in this guide. Two controls adjust the frequency response of the overall mix. 10kHz is a shelving HF control, 80Hz is a shelving LF control. Both provide up to 6dB cut or boost. The response is flat at the centre positions. Where possible use only small amounts of EQ, or none at all. The LF control is tuned very low to boost frequencies well below the 80Hz turning point. This lets you bring out thumping lows from big system subs without wooliness. These controls should be used for performance rather than room or equipment compensation. If the system has been properly specified and installed then it should reproduce the music with an accurate flat response. Rear panel insert points are provided for patching in processing equipment such as equalisers needed for room compensation. 10kHz Master EQ -6 +6 80Hz -6 +6 MASTER EQ 4 3 2 1 0 10 5 6 7 8 9 Master level Controls the overall level of the house mix. It ranges from fully off to 0dB unity gain. For normal operation it should be used near to or at its fully clockwise position. The XLR delivers +4dBu output level when the MASTER level is fully clockwise and the VU meters read `0'. This should match most systems. Internal option jumpers are available for 0dBu operation if preferred. MASTER XONE:V6 User Guide 11 Booth Controls The DJ's local loudspeakers are fed from the console BOOTH output. The booth mix is sourced from the master mix. It is derived post insert so that the DJ hears exactly what is being fed to the house system. The DJ microphone signal can be included or removed from the booth mix. The same mix feeds the recording outputs. 10kHz MIC INSERT Mic To Booth switch -6 +6 100Hz This rear panel switch is recessed to protect it from accidental operation once set. Use a pen or similar pointed object to change its setting. Set the switch out (flush with panel) to include the microphone signal in the booth and recording mix. Set the switch in (pressed) for a music only mix. MIC TO BOOTH -6 4 3 2 1 0 5 6 +6 7 8 9 10 Booth EQ BOOTH 11 Two controls adjust the frequency response of the overall mix. 10kHz is a shelving HF control, 100Hz is a shelving LF control. Both provide up to 6dB cut or boost. The response is flat at the centre positions. Where possible use only small amounts of EQ, or none at all. The LF control is tuned slightly higher than the master EQ to better match the performance of the speakers typically used. The booth EQ only affect the booth output. It does not affect the headphones or recording feeds. Booth level Controls the overall level of the booth mix. It ranges from fully off to 0dB unity gain. For normal operation it should be used near to or at its fully clockwise position. 12 XONE:V6 User Guide Headphones Controls The DJ headphones is sourced from the booth mix and switched cue system. Headphone sockets are provided on both the front and rear panels. TONE Tone control This combines the LF and HF equaliser into one, easy to use control. At centre position the frequency response is flat. Turning clockwise boosts the high frequencies while cutting the lows. Turning anti-clockwise boosts the lows while cutting the highs. Use this to check the frequency makeup of the music you are cueing in the headphones. This control balances the level of cue signal and booth (music) signal in the headphones. Fully anti-clockwise, only cue signal is routed. Fully clockwise, only booth mix is routed. At centre position, equal cue and booth signal is mixed together. Use the control when auditioning new tracks and experimenting with how they may sound when added to the mix. Controls the overall level of the headphones. It ranges from fully off to maximum volume. LF HF CUE/MIX Cue / Mix CUE 4 3 2 1 0 5 6 MIX 7 8 9 10 11 Phones level Headphones are available with different impedance specification, typically between 8 and 600 ohms. The XONE:V6 is designed to operate with headphones in the range 30 to 600 ohms. For best performance we recommend the high quality 70 or 100 ohm type popular with top DJs. To avoid damage to your hearing do not operate any sound system at excessively high volume. This also applies to any close-to-ear monitoring such as headphones. Continued exposure to high volume sound can cause frequency selective or wide range hearing loss. Make sure that your system complies with any venue sound level and noise regulations which may apply. PHONES Important Note about Hearing: XONE:V6 User Guide 13 Channel Connectors Each channel has two stereo inputs. CH1-4 provide line and RIAA inputs. CH5 and 6 provide two line inputs. L A R LINE A L R PHONO/ LINE L and R inputs RCA phono sockets. The PHONO input provides gain and RIAA equalisation for turntable cartridges. Note that CH1-4 have internal option jumpers to disable RIAA if you want to use the inputs for additional line sources. The LINE inputs have a maximum gain of +10dB to accept signals as low as -10dBu. Note that there are internal option jumpers to reduce this gain to +6 or 0dB if preferred. Connect the ground wires of the turntables to the chassis ground terminals provided. Insert SND A pair of RCA phono sockets for each side of the stereo signal lets you insert external processing such as an effects unit, equaliser or other channel signal processing device. This is done by breaking the signal path after the hi-pass filter and before the rotary fader. The insert operates at 0dBu. With nothing inserted, the jumper plugs must be plugged in as shown so that the send signals are passed on to the return inputs. These plugs are provided with the console. To insert external equipment, first unplug the jumpers. Keep them in a safe place to use again in the future if needed. Use RCA phono cables to connect the insert send (SND) to the equipment input, and to connect the equipment output back to the insert return (RTN). Make sure the equipment is set to operate around 0dBu and has 0dB (unity) gain from its input to output. RTN SND RTN Important ! Make sure the jumper plugs are pressed fully in. To ensure the fine standard of sonic performance for which the XONE:V6 has been designed, use only the highest grade professional cables. Avoid the use of domestic grade cables. A note about cables 14 XONE:V6 User Guide Microphone Connectors MIC INPUT The microphone input is used for the DJ microphone. A hi-pass filter is built in to reduce low frequency handling noise, popping and proximity effect. An insert point is provided for patching in processors such as a compressor. Mic input MIC INSERT Balanced XLR, pin 2 hot. Maximum gain available is +60dB. We recommend you use a rugged, professional grade, dynamic microphone specifically designed for the vocal application. This should be low impedance (less than 600 ohms), balanced and have a cardioid (directional) response to avoid feedback problems. Phantom power MIC TO BOOTH An internal option jumper is provided to select +30V to the XLR pins for use with microphones which require phantom power. Check the mic manufacturer's specification regarding these power requirements. WARNING Do not connect unbalanced sources or cables to the XLR input when phantom power is applied. To avoid loud clicks always turn the mic level down before plugging or unplugging phantom powered microphones. Insert Unbalanced TRS (stereo) jack wired tip = send, ring = return, sleeve = common ground. With nothing plugged in the signal is passed through internal switch contacts within the socket. The insert operates at 0dBu. Adjust the external equipment to operate around 0dBu and with 0dB (unity) gain from its input to output.
