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 output
mini jack.
You can listen to the combined audio level in your headphones. After
setting the Send levels for the highest level you can send without
distortion as indicated by the LED meter, listen to the audio in your
headphones and set the <Caller> level to match the Send level. Or if your
recording device has a meter, you can use that to match the <Caller>
level to the Send level.
