Owner's Manual 3 ONYX 80 SERIES Introduction Thank you for choosing a Mackie Onyx 80 Series professional live mixing console. The Onyx 80 Series of mixers feature all-new analog circuitry and the latest technologies for live sound reinforcement in a durable, road-worthy package. The Onyx 80 Series mixing consoles come in four sizes: the 24-channel Onyx 2480, 32-channel Onyx 3280, 40-channel Onyx 4080, and the flagship 48-channel Onyx 4880. The master section and channel strip configuration are the same for all four models, the only difference being number of channels. The Onyx 80 Series consoles are equipped with our new premium precision-engineered studio-grade Onyx mic preamps. Mackie is renowned for the high-quality mic preamps used in our mixers, and the Onyx mic pre's are better than ever, with specifications rivaling expensive stand-alone mic preamplifiers. Each mono channel strip features an individual phantom power switch, low-cut filter, polarity switch, pre-EQ channel insert, and an all new four-band EQ design with sweepable mids and EQ bypass switch. All mono channels have eight Aux sends with a stereolink function (can provide up to four IEM mixes), Pan, Mute and Mute Group assign, PFL Solo, 100 mm Fader, Group and Main Mix assign, and four signal-level indicators. In addition, balanced direct outputs are provided on DB-25 connectors (eight channels per connector) for multitrack recording. The master section features eight stereo Aux inputs, eight Master Aux sends, eight Group Masters, an Aux/ Group Flip function, a 10x2 Matrix, a Phones/Monitor section, and a Talkback section with routing switches that allow you to communicate through the Aux Sends, Group outputs, or the L/R mix. HOW TO USE THIS MANUAL We know that many of you can't wait to get your new mixing console hooked up, and you're probably not going to read the manual first (sigh!). So the next section is a Quick-Start Guide to help you get the mixer set up fast so you can start using it right away. Right after that are the ever popular hook-up diagrams that show typical mixer setups for live sound, recording and mixdown. Then, when you have time, read the Features Description section. This describes every knob, button, and connection point on the Onyx 80 Series, roughly following the signal flow through the mixer. Throughout this section you'll find illustrations with each feature numbered. If you want to know more about a feature, simply locate it on the appropriate illustration, notice the number attached to it, and find that number in the nearby paragraphs. This icon marks information that is critically important or unique to the Onyx 80 Series. For your own good, read them and remember them. They will be on the final test. This icon leads you to in-depth explanations of features and practical tips. While not mandatory, they usually have some valuable nugget of information. A PLUG FOR THE CONNECTOR SECTION Appendix B is a section on connectors: XLR connectors, balanced connectors, unbalanced connectors, and special hybrid connectors. More resources on our website at www.mackie.com. THE GLOSSARY: A Haven of Non-Techiness for the Neophyte The "Glossary of Terms" is a fairly comprehensive dictionary of pro-audio terms. If terms like "clipping," "noise floor," or "unbalanced" leave you blank, refer to this glossary for a quick explanation. Please write your serial number here for future reference (i.e., insurance claims, tech support, return authorization, etc.) Purchased at: ARCANE MYSTERIES ILLUMINATED "Arcane Mysteries" discusses some of the down `n' dirty practical realities of microphones, fixed installations, grounding, and balanced versus unbalanced lines. It's a goldmine for the neophyte, and even the seasoned pro might learn a thing or two. Date of purchase: 4 ONYX 80 SERIES Getting Started READ THIS PAGE!! Even if you're one of those people who never read manuals, all we ask is that you read this page now before you begin using the Onyx 80 Series. You'll be glad you did! 3. 4. Owner's Manual a line input such as a CD player or tape recorder output. Be sure that the volume of the input source is the same as it would be during normal use. If it isn't, you might have to readjust these levels during the middle of the set. Adjust the channel's GAIN [5] control so that the LEDs on the Left Solo meter stay around "0" and never go higher than "+7." If you'd like to apply some EQ, do so now and return to step 3. Remember to push in the EQ IN/OUT [12] button or the EQ controls won't do anything. Disengage that channel's PFL solo switch. Repeat for each channel. Zero the Controls 1. 2. 3. 4. Turn down the channel GAIN, AUX, and Fader controls, and center the channel EQ and PAN controls. Set all push button switches to their "out" positions. In the Master section, turn all the rotary knobs "down," the switches "out," and the faders down. Turn the POWER switch off. 5. 6. Instant Mixing 1. Leave the microphone plugged into channel 1 and connect a keyboard, guitar or other instrument to channel 2. Be sure to "Set the Levels" for channel 2 as described above. To get sound out of the speakers, push in the MAIN MIX assign switch [21] next to the faders on channels 1 and 2, turn up channel 1 and 2 faders [33] to the "U" mark and slowly turn up the left and right MAIN MIX [60] faders to a comfortable listening level. Sing and play. You're a star! Adjust the faders for channels 1 and 2 to bring your voice and your instrument up and down to create your own mix. Connections If you already know how you want to connect the Onyx 80 Series mixing console, go ahead and connect the inputs and outputs the way you want them. If you just want to get sound through the mixer, follow these steps: 1. Plug a microphone or other signal source into channel 1's MIC or LINE input [67/68]. If it's a line-level input, push in the LINE [2] switch. Plug in the detachable linecord, connect it to an AC outlet, and turn on the Onyx 80 Series' POWER switch [85]. Connect cords from the Onyx 80 Series' MAIN OUTS [79] (XLR connectors or 1/4" TRS connectors on the rear panel) to your amplifier. Hook up speakers to the amp and turn it on. If the amplifier has level controls, set them however the manufacturer recommends (usually all the way up). 2. 3. 2. Other Nuggets of Wisdom · For optimum sonic performance, the channel and MAIN MIX faders should be set near the "U" (unity gain) markings. Always turn the MAIN MIX faders, GROUP faders, and MONITOR knob down before making connections to and from your Onyx 80 Series. When you shut down your equipment, turn off the amplifiers first. When powering up, turn on the amplifiers last. Never listen to loud music for prolonged periods. Please see the Safety Instructions on page 2 for information on hearing protection. Save the shipping box! You may need it someday, and you don't want to have to pay for another one. 3. · 4. · Set the Levels To set the channel GAIN controls, it's not even necessary to hear what you're doing at the outputs of the mixer. If you want to listen while you work, plug headphones into the PHONES jack [65] on the front panel, then set the PHONES knob [64] about one-quarter of the way up and the SOLO LEVEL [61] about halfway up. The following steps must be performed one channel at a time. 1. 2. Push in the channel's PFL [22] solo switch. Play something into the selected input. This could be an instrument, a singing or speaking voice, or · · That's it for the "Getting Started" section. Next comes the "Hookup" section that shows you some typical ways that you might use the Onyx 80 Series in real applications. After that, take the grand tour of the mixer, with descriptions of every knob, button, input, and output. We encourage you to take the time to read all of the feature descriptions, but at least you know it's there if you have any questions. Owner's Manual 5 ONYX 80 SERIES Hookup Diagrams This hookup diagram demonstrates how you can do a live multitrack recording using the DIRECT OUTs. The DIRECT OUTs provide an analog balanced direct output for each channel, post-EQ. Aux Send 1 is used for stage monitors, and Aux Sends 3 and 4 are a stereo pair driving an IEM system. Aux Sends 5/6 and 7/8 could provide two more stereo sends for IEM systems.

Onyx 2480 House of Worship Owner's Manual 9 ONYX 80 SERIES Onyx 80 Series Features Channel Strips Depending on the model that you purchased, there are 24, 32, 40, or 48 channel strips. Each channel has a mic and line input connector and an insert jack for connecting an external signal processor. 3. Low-Cut Switch The Low-Cut switch, often referred to as a high-pass filter, cuts bass frequencies below 100 Hz at a rate of 18 dB per octave. We recommend that you use the Low-Cut filter on every microphone application except kick drum, bass guitar, bassy synth patches, or recordings of earthquakes. These aside, there isn't much down there that you want to hear, and filtering it out makes the low stuff you do want much more crisp and tasty. Not only that, but the Low-Cut filter can help reduce the possibility of feedback in live situations and it helps to conserve amplifier power. Another way to use the Low Cut filter is in combination with the LOW EQ on vocals during live performances. Many times, bass shelving EQ can really benefit voices. Trouble is, adding LOW EQ also boosts stage rumble, mic handling clunks, and breath pops. Low Cut removes all those problems so you can add LOW EQ without losing a woofer. +15 +10 +5 1. 48V Phantom Power Switch 1 48V LINE 0 100Hz 30 40 20 U Most professional condenser microphones require phantom power, which is a low-current DC voltage delivered to the microphone on pins 2 and 3 of the XLR microphone connector. Push in the 48V button if your microphone needs phantom power. An LED lights just above the button to indicate that phantom power is active on that channel. Dynamic microphones, like Shure's SM57 and SM58, do not require phantom power. However, phantom power will not harm most dynamic microphones should you accidentally plug one in while the phantom power is turned on. Be careful with older ribbon microphones. Check the manual for your microphone to find out for sure whether or not phantom power can damage it. Note: Be sure the MAIN MIX faders [60] are turned down when connecting microphones to the MIC Inputs, especially when phantom power is turned on, to prevent pops from getting through to the speakers. -20dB U U +40dB GAIN 60 EQ HIGH 12 kHz -15 +15 2k FREQ 400Hz 8kHz U 0 ­5 ­10 ­15 20Hz 100Hz 1kHz 10kHz 20kHz HIGH MID -15 +15 400 Here's what the combination of LOW EQ and Low Cut looks like in terms of frequency curves. Low Cut with Low EQ Boosted FREQ 100 U 2k 4. Polarity Switch Pushing in this switch simply reverses the polarity of the signal. This provides an easy way to correct a microphone or line source whose polarity is opposite from the other microphones, either from a miswired cable or from not following the AES standard for Pin 2/Pin 3. LOW MID -15 U +15 LOW 80 Hz -15 +15 EQ OUT IN 5. GAIN Control If you haven't already, please read "Set the Levels" on page 5. The GAIN control adjusts the input sensitivity of the mic and line inputs. This allows the signal from the outside world to be adjusted to optimal internal operating levels. If the signal is plugged into the XLR jack, there is 0 dB of gain (unity gain) with the knob turned all the way down, ramping up to 60 dB of gain fully up. 2. MIC/LINE Switch This button switches between the MIC and LINE inputs. When the button is out (MIC), the XLR MIC input is used and the LINE input is disconnected. When the button is pushed in, the 1/4" input is used and the XLR MIC input is disconnected. 10 ONYX 80 SERIES Owner's Manual When connected to the 1/4" jack, there is 20 dB of attenuation all the way down, and 40 dB of gain fully up, with a "U" (unity gain) mark at about 10:00. the male vocal range and the fundamentals of some lower instruments (guitar, lower brass). 6. HIGH EQ This control gives you +10 up to 15 dB boost or cut +5 at 12 kHz, and it is also 0 flat at the center detent. ­5 Use it to add sizzle to ­10 cymbals, and an overall ­15 20Hz 100Hz 1kHz 10kHz 20kHz sense of transparency or edge to the keyboards, High EQ vocals, guitar, and bacon frying. Turn it down a little to reduce sibilance, or to hide tape hiss. +15 10. LOW MID FREQ +15 +10 +5 0 ­5 ­10 ­15 20Hz 100Hz 1kHz 10kHz 20kHz Mid EQ Freq Sweep This knob ranges from 100 Hz to 2 kHz and determines the center frequency for the LOW MID EQ filter. This allows you to zero in on the precise narrow band of frequencies you want to have affected by the LOW MID EQ. 11. LOW EQ +15 +10 +5 7. HIGH MID EQ +15 +10 Short for "midrange," this knob provides 15 dB +5 of boost or cut centered 0 at the frequency deter­5 mined by its FREQ knob ­10 (see HIGH MID FREQ ­15 20Hz 100Hz 1kHz 10kHz 20kHz next). Midrange EQ is High Mid EQ often thought of as the most dynamic because the frequencies that define any particular sound are almost always found in this range. The HIGH MID EQ range (400 Hz to 8 kHz) includes the female vocal range as well as the fundamentals and harmonics for many instruments. 0 ­5 ­10 ­15 20Hz 100Hz 1kHz Low EQ This control gives you up to 15 dB of boost or cut at 80 Hz. The circuit is flat (no boost or cut) at the center detent position. This frequency represents the punch in 10kHz 20kHz bass drums, bass guitar, fat synth patches, and some really serious male singers. Note: Used in conjunction with the Low Cut switch, you can boost the LOW EQ without injecting tons of infrasonic debris into the mix. 8. HIGH MID FREQ +15 +10 +5 12. EQ IN/OUT Switch This knob ranges from 400 Hz to 8 kHz and determines the center frequency for the HIGH MID EQ filter. This allows you to zero in on the precise narrow band of frequencies you want to have affected by the HIGH MID EQ. This is a true hardware bypass of the Perkins EQ circuitry to insure that there is no coloration of the signal if the EQ is not needed. When this button is out, the EQ controls have no effect on the signal. You can use this switch to make an A/B comparison between the EQ'd signal and the signal without EQ. We have completely redesigned the EQ circuits in the Onyx Series of mixers, based on the designs of Cal Perkins, an industry-leader in audio engineering for over three decades and long-time Mackie collaborator. This "neo-classic" design provides the sweet musicality of the British EQ sound, while still maintaining 15 dB of boost and cut with optimum Q and minimum phase shift (in other words, it gives you plenty of control and is pleasing to the ear!).
