VLZ4 Stereo Inputs and Returns:  

Mono, Stereo, Whatever

Stereo line inputs and stereo returns are a fine 

 

example of our philosophy (which we just made up) 

 

of Maximum Flexibility with Minimum Headache. 

 

The inputs and returns will automatically be mono 

 

or  stereo, depending upon how you use the jacks. 

 

Here’s how it works:

A mono signal should be patched into the input or 

 

return jack labeled left (mono). The signal will be 
routed to both the left and right sides of the return 
circuit, and will show up in the center of the stereo  
pair of buses it’s  assigned to, or it can be panned    
with the  pan [24] control.

A stereo signal, having two plugs, should be patched 

into the left (mono) and the right input or return jacks. 
A jack switch in the right jack will disable the mono 
function, and the  signals will show up in stereo.

A mono signal connected to the right jack will show 

up in the right bus only. You probably will only want to 
use this sophisticated effect for special occasions.

Microphone Stand

The bottom panel of 

the 802VLZ4 has three 
non-threaded holes 
that allow it to be 
fitted with an optional 
microphone stand 
adapter. This allows 
you to support the 
mixer on a standard 
mic stand, and adjust 

its height and level to 

whatever suits your 
strangely-complex set 
of preferences.

1.  Order the Atlas AD-11B mic stand adapter 

available from many a fine music store.    
(It is made and distributed by Atlas Sound.)

2.  Use three self-tapping machine screws  

 

6-32 x 1/4" long to secure the adapter to    
the bottom of the 802VLZ4.

Do not use screws that are longer then 1/4" as 
these could damage the circuit boards. Do not 
use any shorter screws, or the adapter will not 
be securely fixed to the mixer.

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.

Using the Send Only on an Insert Jack

If you insert a TS (mono) 1⁄4" plug only  partially (to 

the first click) into a VLZ4  insert jack, the plug will not 
activate the jack switch and will not open the insert 
loop in the  circuit (thereby allowing the channel signal 
to continue on its merry way through the mixer).

This allows you to tap out the channel or bus signal 

without interrupting normal operation.

If you push the 1⁄4" TS plug in to the second click, 

you will open the jack switch and create a  direct out, 
which does interrupt the signal in that channel. See the 
illustration below.

NOTE: Do not overload or short-circuit the signal you 

are tapping from the mixer. That will affect the internal 

signal.
