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 LEDs
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 output mini jack.
