VU Meter
The VU meter shows the mix of both microphones and the tape
signal going out over the phone line or handset interface.
Send Side (To Phone Line)
There are separate volume controls for the two microphone inputs
and the line 3 input RCA jack. You can use all three inputs at the
same time. Mic 1 also has a Mic/Line selector switch which lowers
the gain on the Mic 1 XLR jack by 30 dB to allow a balanced line
level input.
Receive Side (From Phone Line)
The receive side has separate controls for headphone output level
and mix audio output level. The Line Out control adjusts the signal
going out of the balanced XLR jack marked Balanced Line Out. This
is either a mix of both sides of the telephone call at telephone band-
width (200 Hz - 3400 Hz) or a clean mic / line input mix at full band-
width (80 Hz - 16 KHz).
Headphones
The built-in headphone amplifier is strong enough to power two pair
of headphones or a small desktop speaker. The left and right
channels contain the same mono signal, but are powered by
separate amplifier channels. These jacks will drive either two 1/4"
stereo plugs or two 1/4" mono plugs.
Talkback Feature
A built in speaker lets you monitor the phone line during call setup
and station breaks. The monitor speaker volume is controlled by the
headphone volume control and has an additional on / off switch. An
internal push-to-talk microphone also helps when setting up your call.
The speaker switches off when the microphone button is pushed on
to prevent feedback.
Ringer
RemoteMix 3 / 3.m has an internal ringer for incoming calls.This can
be turned off using the switch on the side of the unit.
