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 speak-
ers, 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 Chan-
nel 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 goose-
neck mounted microphone. The connector is rotated such that
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 sup-
plied 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 ground-
ing 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 the RaneNote "Sound System Interconnection"
included with this manual for further information on system
grounding.
a right angle connector may be used when connecting 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.
