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 Trilobular thread rolling screws
6-32 x 1/4" long to secure the adapter to
the bottom of the 802VLZ4 [see below].
Do not use screws longer than 1/4", as these
could damage the circuit boards. Do not use
screws shorter than 1/4", or the adapter will not
be securely fixed to the mixer.
3. Do not order the Atlas AD-11, as this is a pack
of 100. If you do, please send for the informa-
tive booklet entitled
99 things to do with a mic
stand adapter .

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.
