1202VLZ4 Features • Introduction 12-channel mixer featuring our signature high-headroom, low-noise design • 4 boutique-quality Onyx mic preamps • Ultra-wide 60 dB gain range • 128.5 dB dynamic range • +22 dBu line input handling • Extended frequency response • Distortion under 0.
We realize that you must be really keen to try out the mixer. Please read the safety instructions on page 2, then have a look through some of the features and details in this manual. Setup Use the mixer in a nice clean and dry environment, free from dryer lint and dust bunnies. Zero the controls 1. Fully turn down all the knobs to minimum, except for the channel EQ and pan controls, which should be centered. 2. Make sure all buttons are in the out position. Connections 1.

1202VLZ4 Patchbay Description 1 2 3 4 5 At the risk of stating the obvious, this is where you plug everything in: microphones, line-level instruments and effects, headphones, and the ultimate destination for your sound: PA system, DAW, etc. See Appendix B for further details and drawings of the connectors you can use with the 1202VLZ4. Also see the channel strip description on page 13 for details of the signal routing from the XLR and line inputs. 1.
Each low cut switch, often referred to as a high pass filter (all depends on how you look at it), cuts bass frequencies below 75 Hz at a rate of 18 dB per octave. We recommend that you use low-cut on every microphone application except kick drum, bass guitar, or bassy synth patches. 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.
1202VLZ4 7 9 10 11 12 7. Stereo Returns This is where to connect the outputs of parallel effects devices (or extra audio sources). These balanced inputs are similar to the stereo line in [2] inputs (without EQ, aux sends, pan, mute, and solo). The circuits will handle stereo or mono, balanced or unbalanced signals, either instrument level, –10 dBV or +4 dBu. They can be used with just about any pro or semipro effects device on the market.
14 12. Headphones Out This stereo jack will drive any standard headphone to very loud levels. To learn how signals are routed to these outputs, see source matrix [33] on page 16. If you’re wiring your own cable for the phones output, follow standard conventions: Tip = Left channel Ring = Right channel Sleeve = Common ground WARNING: When we say the headphone amp is loud, we’re not kidding. It can cause permanent ear damage. Even intermediate levels may be painfully loud with some earphones.

Power Switch Just in case you lose the cord provided with the 1202VLZ4, its power jack accepts a standard 3-prong IEC cord like those found on most professional recorders, musical instruments, and computers. Press the top of this rocker switch inwards to turn on the mixer. The power LED on the top surface of the mixer will glow with happiness, or at least it will if you have the mixer plugged in to a suitable live AC mains supply.
The eight channel strips look alike, and function identically. The only difference is that the four on the left are for individual mics or mono instruments and have more gain available, while the next four are for either stereo or mono line-level sources. (Each of the stereo channel strips is actually two complete circuits. The controls are linked together to preserve stereo.) We’ll start at the bottom and work our way up… “U” Like Unity Gain VLZ4 mixers have a “U” symbol on almost every level control.
1202VLZ4 [15] and phones [12] outputs. If you want the alt 3–4 signals to go back into the main mix, engage the assign to main mix [36] switch, and the control room/submix [34] level control becomes the one knob to control the levels of all the channels assigned to alt 3–4. Another way to do the same thing is assign the channels to the alt 3–4 mix, then patch out of the alt 3–4 output [16]back into an unused stereo channel line input [2].
This control gives you up +15 to 15 dB boost or cut above +10 +5 12 kHz, and it is also flat 0 at the detent. Use it to –5 add sizzle to cymbals, –10 and an overall sense of –15 transparency, or edge to 20 100 1k 10k keyboards, vocals, guitar High EQ and bacon frying. Turn it down a little to reduce sibilance, or to hide tape hiss. Hz Hz Hz Hz Each aux send level ranges from off through unity (the center detent position) on up to 15 dB of extra gain (when turned fully clockwise).
1202VLZ4 Output Section 33. Control Room Source Matrix Typically, the engineer sends the main mix to an audience (if live) or a mixdown deck (if recording). But what if the engineer in the control room needs to hear something other than the main mix? With the 1202VLZ4, the engineer has several choices of what to listen to. This is one of those tricky parts, so brace yourself. 33 37 36 34 35 32 32.
A Word About Pre-Fader Solo (PFL) Engaging a channel’s solo [24] switch will cause this dramatic turn of events: Any existing control room source selections will be replaced by the solo signal, appearing in the control room, headphones, and in the right meter. The audible solo levels are then controlled by the control room / submix [34] knob. The solo levels appearing on the right meter display are not controlled by anything — you wouldn’t want that.
1202VLZ4 At the risk of creating another standard, 1202VLZ4 mixers address the need of both crowds by calling things as they are — 0 dBu (0.775 V) at the output shows as 0 dB VU on the meters. What could be easier? By the way, the most wonderful thing about standards is that there are so many to choose from. These outputs can be fed to the inputs of a reverb or other device. From there, the outputs of this external device are fed back to the mixer’s stereo return [7] jacks.
Signals passing through these controls will proceed directly to main mix, with one exception (see paragraph below). The stereo returns do not have mute/alt 3-4 switches, so if you want these signals to get to the alt 3-4 mix, you’ll have to patch the effects device’s outputs into one of the stereo channels, and mute/alt those channels. 41. Return To Aux 1 If you want to add reverb or delay to the stage monitor mixes of aux 1, this is the switch for you.
1202VLZ4 Appendix A: Service Information If you think your 1202VLZ4 has a problem, please check out the following troubleshooting tips and do your best to confirm the problem.

You may find the answer to the problem without having to send your mixer away.
The male XLR connectors provide a balanced linelevel signal that represents the end of the mixer, where the fully mixed stereo signal enters the real world. Connect these to the left and right line-level inputs of powered speakers or to the left and right line-level inputs of an amplifier (with speakers already attached). Be sure the cables are wired per AES (Audio Engineering Society) standards: accept 1-plug-type stereo microphones.
1202VLZ4 Unbalanced RCA Connector TRS Send/Receive Insert Jacks RCA-type plugs (also known as phono plugs) and jacks are often used in home stereo and video equipment and in many other applications. RCA plugs are unbalanced. Connect the signal to the center post and the ground (earth) or shield to the surrounding “basket.” Be sure the cables are wired per AES (Audio Engineering Society) standards: Single-jack inserts are three-conductor, TRS-type 1⁄4" phone.
MONO PLUG Channel Insert jack Direct out with no signal interruption to master. Insert only to first click. MONO PLUG Channel Insert jack Direct out with signal interruption to master. Insert all the way in to the second click. STEREO PLUG Channel Insert jack For use as an effects loop. (Tip = Send TO effect, Ring = Return FROM effect).
