User Manual

1. Mic inputs 1 and 2 are balanced XLR jacks with low-noise amplifi-

ers.

2. Mic inputs 3 and 4 are balanced XLR jacks with low-noise amplifi-

ers. A mic/line selector switch adds a 40 dB pad for a line level

balanced input.

A switch on each of the 4 XLR mic inputs will provide 48 V phan-

tom power. If inputs 3 or 4 are set to Line input, the 48 V will not

be present at the XLR jack even if the switch is left on.

3. The stereo 3.5 mm line level input can be used instead of or in

addition to the channel 4 XLR input. You can connect either a

mono or stereo signal to this mini jack. If you use a stereo input,

both channels will immediately be summed together. Then the

audio from the mini jack and the XLR would be added together

and treated as one mono signal on channel 4.

disk or other recording device. The Master Output will be on the

Left channel and the Receive mix from the phone line and/or Cue

input will be on the Right channel.

5. The Master Output is a balanced XLR jack that contains the sum

of all four input XLRs and the 3.5 mm input. This audio signal has

a full 20 Hz to 20 kHz bandwidth.

6. Each of the four mono headphone jacks can be set to hear either

a mix of local mic and line inputs or the return from the phone line

which will include a lesser amount of your local mix.
