REAR PANEL

WIRING SCHEME

All of the input and output connectors are "pin 2 hot" meaning that pin number 2 on the XLR

connecting cables carries the positive side of the balanced signal. Pin number 3 is "cold", carrying

the negative polarity and pin 1 is the shield.

The 1/4" TRS (Tip/Ring/Sleeve) jacks are wired so that when you use 3 conductor cables and bal-

anced signals, the tip is hot, the ring is cold and the sleeve is the shield. The 1/4" jacks can also

be used with 2 conductor unbalanced cables. In this case, the tip is hot and the ring and sleeve are

grounded.

MIC INPUT

Connect the cable from your microphone here. If your mic requires phantom power, ensure that

the phantom power switch on the front panel is turned off before connecting your mic. Flip the

front panel Input Select switch to Mic to activate this input.

LINE INPUTS

There are two line inputs to allow you to run a variety of connecting cables from your line level

sources. The XLR connector on the top is a balanced input capable of receiving +4 dBu or -10

dBv signals. The input level sensitivity is adjusted with the PRE GAIN control.

The 1/4" phone connector on the bottom is also a balanced +4/-10 input using the TRS connecting

scheme. This requires a cable with "stereo" phone jacks to be used as a balanced input. It can also

be used with an unbalanced source using a standard two conductor cable. If you plug a connector

into the phone jack input, this will override anything plugged into the XLR input.
