Indicators Cont’d
8.
OH LED
Lit when you are on line with a call (Off-Hook).
9.
Send LEDs
Displays the signal level going to the phone line. The goal is to drive the
phone line audio at levels high enough to avoid phone line noise, but not
so loud as to cause excessive clipping. Adjust the
<Send>
level control
so that you rarely see flashes of the red -3dB peak
<Send>
LED. These
flashes should occur only during loud speech bursts. If the red LED
stays lit for extended periods you can assume that much of your speech
is being clipped or distorted. In this case you should lower the
<Send>
volume control for the input that is causing the clipping.
10.
Power LED
Lit when unit is plugged in and receiving power.
11.
Caller LEDs
Displays the signal level coming in from the phone line, after the DSP.
This signal level will not change when you adjust the
<Caller>
knob.
The
<Caller>
level control knob does not change what you see on these
LEDs. Adjust the
<Caller>
level control to give you the best signal level at
the
<Caller>
XLR output or the Caller channel of the
<Stereo Out>
mini jack.
