Audio I/O and Level Adjustments
You can connect a professional quality, low impedance microphone
directly to either XLR microphone input on the front panel. A
microphone can also be connected to the mic/line input on the rear
panel, setting the level switch accordingly. High impedance
microphones, or microphones with other than XLR connectors must use
an external matching transformer or adapter. Phantom power is not
provided. Balanced monaural line level audio is input through the XLR
Input 3 connector on the rear panel, setting the level switch accordingly.
Mic/Line mixing is accomplished using the three input level controls
located on the front panel. Adjust the levels so that the green ‘NORM’
indicator illuminates when audio is present, and the red ‘CLIP’
indicator does not. It is recommended, but not necessary, to turn the
level control down if an input is not connected. If the red ‘CLIP’ light
illuminates, the audio will be distorted.
Two sets of headphones with ¼ ” jacks can be used without adapters.
When stereo headphones are used, the output will be monaural, to both
ears. Do not use monaural headphones with 2-conductor plugs . The
audio source to the headphones, local or return audio, can be adjusted
using the two level controls located above each headphone output.

or amplifying equipment is available through two ¼ ” connectors on the
rear panel, one for local audio and one for return audio. Balanced line
