Overview - AudioArts Engineering R-5 Owner's Manual

An alternate set-up might feed the
announcer mic signal (taken from that
mic channel's insert out point) into the
phone channel's external input, allowing
the caller to hear the announcer without
having to disturb the operator's mic
channel assign switch settings.
See also OUTPUTS chapter, page 5-2,
for additional information on phone
channel operation.

OVERVIEW

This specialized input channel is designed to handle telephone call-in
talk segments. It makes use of the console's mono TEL bus to generate a
mix-minus feed to the caller; any inputs assigned to the TEL bus are fed to
the caller, whose voice signal is returned via the dedicated phone channel
fader and then routed (through ASSIGN switches) to either the PROGRAM
bus for live on-air broadcast or to the AUDITION bus for delayed tape
recording.
A CUE button allows interviewing the caller prior to airing. A separate
input (EXT, see flow diagram below) goes directly to the console TEL bus;
it may be used to introduce an additional feed to the caller.
The phone channel is used in conjunction with your station's telephone
hybrid, which interfaces between the console and the station's call-in
phone lines. The hybrid's output feeds the phone channel caller input. The
console's mono TEL output provides the signal going back to the caller;
this output feeds the hybrid's input.
A typical call-in segment might proceed as follows:
1) Caller phones in, announcer picks up off-air during a track play to
set up the call. He assigns his mic channel to TEL (first deactivating PGM/
AUD assignments so his voice doesn't go out over the air), hits his mic ON
switch, hits the phone channel CUE switch and talks to the caller, whose
voice comes up on the console's CUE speaker (and anywhere else CUE
has been programmed to interrupt—typically HDPN and/or CR). When he
is ready to take the call on-air, the operator
2) Deactivates CUE on the phone channel and assigns it to PGM,
3) Assigns his MIC channel to PGM (leaving TEL assigned) and does the
segment (caller voice level is controlled by the phone channel fader).
4) If the announcer wants to play any music during the segment, the
appropriate stereo line input is assigned to PGM and TEL, letting the
audience and the caller hear it.
