MP 22z CONNECTION
When first connecting the MP 22z to other components,
leave the power supply for last. This gives you a chance to
make mistakes and correct them without damaging your
fragile speakers, ears and nerves.
All of the line level inputs are unbalanced RCA connec-
tors. Inputs PH/LN1, LINE 3, LINE 4 and LINE 5 appear on
Channel A; while PH/LN2, LINE 4, LINE 5 and LINE 6 each
appear on Channel B. The only restriction is the assignment
of the Phono Inputs, one per Channel A and Channel B. So
for you phono only users, Inputs are pretty simple; Phono 1 is
on Channel A and Phono 2 is on Channel B. If you bring a
phono signal into PH/LN 1 or 2 be sure to set the appropriate
Line/Phono switch to PHONO. Like a mic input, a phono
requires a lot of gain plus RIAA equalization.
The Aux Line Input has its own Level control on the front
panel and sums with the other signals before the Master and
Zone Level controls.
The Main Mic Input on the front panel allows use of a
gooseneck mounted microphone. The connector is rotated
such that a right angle connector may be used when connect-
IMPORTANT NOTE
CHASSIS GROUNDING
If your system exhibits excessive hum or buzzing,
there is an incompatibility in the grounding configuration
between units somewhere. Your mission, should you
accept it, is to discover how your particular system wants
to be grounded. Here are some things to try:
1. Try combinations of lifting grounds on units that
are supplied with ground lift switches or links.
2. If your equipment is in a rack, verify that all chassis
are tied to a good earth ground, either through the line
cord grounding pin or the rack screws to another
grounded chassis like the amplifier.
3. Units with outboard power supplies do not ground
the chassis through the line cord. Make sure that these
units are grounded either to another chassis which is earth
grounded, or directly to a known ground by means of a
wire connected to a screw on the chassis with a star
washer to guarantee proper contact.
Please refer to Rane Note 110, "Sound System
Interconnection" included with this manual for further
information on system grounding.
ing via mic cable. The Remote Mic Input is located on the
rear panel and has enough range on it's Level control to
accommodate mic or line level inputs. The Mic Loop has an
unbalanced ¼" TS (Tip/Sleeve) Output (send) and a separate
¼" TS (Tip/Sleeve) Input (return). The effect in this Loop
affects both Mics simultaneously.
Inserting plugs into the Master Loop Return breaks the
signal path thru the unit unless they contain the return from an
outside device that got its signal from the Master Loop Send.
In other words, these are switching jacks—only use a stereo
effects device that passes signal completely patched through.
The Mic and Aux can be switched to appear or not appear
on the Zone 1 Output, and the Mic and Aux can be switched
to appear or not appear on the Tape Output, determined by
the YES/NO switches on the rear panel.
If you are connecting balanced devices (3-conductor) to
either the Input or Output of the MP 22z, consult the included
RaneNote "Sound System Interconnection" for proper wiring
procedures.
