802VLZ4 Features Introduction • 8-channel mixer featuring our signature high-headroom, low-noise design • 3 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.
The following steps will help you set up the 802VLZ4 mixer quickly. 1. Make all initial connections with the power switches OFF on all equipment. Make sure the gain knobs and main mix knob are fully down [counter-clockwise]. Things to Remember • Never listen to loud music for prolonged periods. Please see the Safety Instructions on page 3 for information on hearing protection. • As a general guide, the 802VLZ4 should be turned on first, then the speakers.

Also see the channel strip description on page 16 for details of the signal routing from the XLR and line inputs. 1.

Line Ins (Channels 1–2) These inputs share circuitry (but not phantom power) with the mic preamps, and can be driven by balanced or unbalanced sources at almost any level. You can use these inputs for virtually any signal you’ll come across, from instrument levels as low as –40 dB to operating levels of –10 dBV to +4 dBu, since there is more gain available than on line inputs 3–8.
Effects: Serial or Parallel? Each low-cut switch, often referred to as a high-pass filter (all depends on how you look at it), cuts bass frequencies below 100 Hz at a rate of 18 dB per octave. The next sections toss the terms “serial” and “parallel” around like hacky sacks. Here’s what we mean by them: We recommend that you use low-cut on every microphone application except kick drum, bass guitar, or bassy synth patches.

These outputs are often used to run a nice pair of powered studio monitors in a control room. The source is selected using the source matrix [30] switches (see page 19).
Owner’s Manual 14. Tape Out These unbalanced RCA connections tap the main mix output to make simultaneous recording and PA work more convenient. Connect these to your recorder’s inputs. (See also main mix [29] on page 19.) Mono Out: If you want to feed a mono signal to your tape deck or other device, simply use an RCA Y-cord to combine these outputs. Do not attempt this with any other outputs on the 802VLZ4. 20 19 15.
802VLZ4 Channel Strip Description The five channel strips look alike, and function identically. The first two are for individual mics or mono instruments, and have more gain available. The next strip controls mic or stereo line-level sources, and the last two 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.
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 [9] back into an unused stereo channel line input [3]. If that’s your choice, don’t ever engage the mute/alt 3–4 switch on that stereo channel, or you’ll have every dog in the neighborhood howling at your feedback loop.
802VLZ4 28. Aux 28 These knobs allow you to tap a portion of each channel signal out to another source for parallel effects processing or stage monitoring. Aux send levels are controlled by these knobs and by the aux master [37]. 27 26 24 These are more than just effects and monitor sends. They can be used to generate separate mixes for recording or “mix-minuses” for broadcast. By using aux in the pre mode, these mix levels can be obtained independently of the channel’s level control.
37 36 now, you probably know what the main mix is. Alt 3-4 is that additional stereo mix bus. Tape is the stereo signal coming in from the tape input [13] jacks. 38 Selections made in the source matrix deliver stereo signals to the control room, phones and meter display. With no switches engaged, there will be no signal at these outputs and no meter indication.
802VLZ4 37 36 Note: for stereo channels 3-8, the solo signal is the mono sum of the left (odd-numbered) and right (even-numbered) signals for that channel strip. 38 39 35 33. Assign to Main Mix 30 33 31 34 32 29 Whatever your selection, you can also use the control room [10] outputs for other applications. Its sound quality is just as impeccable as the main outs [16 and 17].
Thanks to the 802VLZ4’s wide dynamic range, you can get a good mix with peaks flashing anywhere between –20 and +10 dB on the meters. Most amplifiers clip at about +10 dB, and some recorders aren’t so forgiving either. For best real-world results, try to keep your peaks between “0” and “+6”. Remember, audio meters are just tools to help assure you that your levels are “in the ballpark.” You don’t have to stare at them (unless you want to). A Word About Aux Sends are outputs, and returns are inputs.

802VLZ4 TRS Send/Receive Insert Jacks Single-jack inserts are three-conductor, TRS-type 1⁄4" phone. They are unbalanced, but have both the mixer output (send) and the mixer input (return) signals in one connector. See the illsutration below. The sleeve is the common ground (earth) for both signals. The send from the mixer to the external unit is carried on the tip, and the return from the unit to the mixer is on the ring.
