OPERATING / SERVICE MANUAL
DMS 22
DUAL MICROPHONE STAGE
QUICK START
Even if you don’t like to read manuals read this part. We’ll make it quick and painless. We promise. Damage to your
equipment, though unlikely, is a possibility if the DMS 22 is used improperly.
Turn both
INPUT GAIN
controls, both
OUTPUT LEVEL
controls and the
STEREO OUTPUT LEVEL
control
fully counterclockwise (CCW). Connect your mic(s) to the
INPUT
jack(s) located on the rear of the unit. If your mic(s)
require phantom power press the
48V PHANTOM POWER
switch(es) on the front panel. Set the
EQ
switch to
OUT
.
Decision time: will you use the DMS 22 to mix your mic(s) to a two channel feed? If the answer is yes, connect the
STEREO OUTPUT(s)
(XLR) located on the rear of the unit to a line level input on your mixer. If the answer is no,
connect the
CHANNEL OUTPUT(s)
(¼" TRS) to a line level input on your mixer. If you are using the
STEREO
OUTPUT(s)
of the DMS 22 then engage the
PAN
switch(es) and set the
PAN
controls where you want them. Plug the
included power supply (
see note below
) into the DMS 22. The yellow
POWER
LED should light and if Phantom Power is
being used the red
PHANTOM POWER
LED should be lit. Now whisper, yell or scream into your mic the loudest sound
you expect to deliver during your session or performance. While doing this adjust the
INPUT GAIN
control so that the
loudest whisper, yell or scream will just barely illuminate the
OL
LED. With that done you can adjust both
OUTPUT
LEVEL
controls and the
STEREO OUTPUT LEVEL
until the desired input level is reached.
Never connect anything except an approved Rane power supply ot the thing that looks like a red telephone jack on
the rear of the DMS 22.
This is an AC input and requires special attention if you do not have an operational power supply
exactly
like the one originally packed with your unit. See the full explanation of the power supply requirements elsewhere
in this manual.
WEAR PARTS:
This product contains no wear parts.
DMS 22 CONNECTION
When connecting the DMS 22 to other components in
your system
leave the power supply for last.
This will give
you a chance to make mistakes and correct them before any
damage is done to your fragile speakers, ears and nerves.
INPUTS
on the DMS 22 are balanced. This means that
standard XLR connectors on the ends of any good quality
cable will work well with the DMS 22 and microphones of
your choosing. As with all Rane products, pin 2 is used for
“hot” or “
+
” polarity, pin 3 is “return” or “
–
” and pin 1 is
chassis ground. If you are not using Phantom Power you may
use either pin 1 or case for shield ground on the DMS 22
Input. However, if you are using Phantom Power, pin 1 must
be shield ground to provide a complete electrical circuit. (See
RaneNote 110, “Sound System Interconnection” included in
this manual for further information on this subject).
OUTPUTS
on the DMS 22 are all fully balanced. On
these Outputs pin 2 or tip is “hot” or “
+
”, pin 3 or ring is
“return” or “
–
” and pin 1 or sleeve is chassis ground. If an
unbalanced Output is desired do not short pin 3 or ring to
ground. Instead use a XLR connector or ¼" TRS (depending
on the output you are using) and do not connect pin 1 or the
sleeve of the ¼" TRS connector. Again, see RaneNote 110 for
more details.
