P-SOLO OPERATION MANUAL
8
Microphone Connection: Microphone connection is made to an XLR MIC IN receptacle
on the rear panel. The wiring configuration used for the microphone connectors on the
P-SOLO is:
 Pin 2 is positive (+)
 Pin 3 is negative (-)
 Pin 1 is shield
Do not attempt to connect unbalanced microphones to the P-SOLO. It is not intended to
operate with this type of microphone.
CAUTION: We recommend that you avoid “hot-patching” the microphone
input if using a patch bay at the microphone input of the
P-SOLO. Please
TURN OFF phantom power and turn down the gain prior to connecting or re-
patching a microphone input routed through a patch bay. Failure to do so
may result in transients that can damage the P-SOLO or equipment that is connected
to its outputs-not to mention your ears!
Output Cable Connection: For ease of connection, two styles of BALANCED OUT
connector, XLR and TRS, are provided. Both connector types are electrically equivalent
and may be used simultaneously to connect to Line Inputs on mixing consoles,
recorders, etc. If both outputs are used, care should be taken to avoid system ground
loops. See “Troubleshooting” section for tips on eliminating hum caused by grounding
problems.
The TRS and XLR output connectors are not electronically isolated. Therefore, if you
connect either one of the output connectors to an unbalanced input, the other connector
will automatically be unbalanced. When connecting an output of the
P-SOLO to an
unbalanced input, you must connect the negative signal pin (pin 3 of the XLR or “ring”
of the TRS) to the shield. Failure to do this will result in audible distortion. The wiring
configuration used for the output connectors on the
P-SOLO is:
For XLR:
 Pin 2 is positive (+)
 Pin 3 is negative (-)
 Pin 1 is shield
For TRS:
 Tip is positive (+)
 Ring is negative (-)
 Sleeve is shield
A Word About Cables.....
Use high-quality, low capacitance cable. Braided shielding and “star quad” type cables
will perform better in electrically noisy environments. Canare
, Mogami (and others)
make high performance cable of this type. Some “house brand” cables are made by
quality manufacturers, but others can be inferior - be careful. Use cables with high-
quality connectors (Neutrik
, Switchcraft, etc.). Avoid excessive cable length. Replace
damaged connectors.
