R-5 / Jan 97
9) You should be able to hear the entire segment as it would be on-air
through the console operator headphones. NOTE you will not be able to
monitor it on the control room speakers, because they will have been
muted by the console operator's mic channel.
10) When the segment is over, de-activate TEL assign on your mic
channel and AUD assign on the phone channel. If you wish, play back the
recorded segment to verify that everything has worked properly.
NOTES: Depending on your particular set-up, you may wish to proceed
in a slightly different manner. For example, the caller could be receiving
your voice by a direct feed from your mic channel's insert out patch point
wired to the phone channel's EXT line input port. If this is the case, then
the console operator's mic signal will always be present on the console's
TEL bus, regardless of input ASSIGN switching, channel ON/OFF switches
and/or fader settings. This makes the segment easier operationally: To do
the set-up, pick up on the call and press the phone channel CUE switch.
Do your set-up using the operator's mic and the console cue speaker, and
when you're ready to go "on-air" turn off phone channel CUE, assign the
phone channel and your mic channel to PGM (or AUD if you're taping for
future airplay), and use their respective faders to control voice levels
(don't forget to press your mic channel's ON switch). If you will be feeding
music to the caller, be sure to assign that line input channel to TEL (so
the caller can hear it through the station hybrid) as well as PGM/AUD ("air/
tape") so the tune will also go out "over-the-air".
Outputs
Typically, the console's main stereo output (PROGRAM) will be the on-
air feed. AUDITION might then be wired to a stereo recording machine,
allowing program segments to be recorded for later airplay. The mono TEL
output is usually used to feed the station's telephone hybrid; it provides the
signal going back to incoming callers. These outputs are all electronically
balanced, with a +4dBu level into 600Ωs when the associated VU meters are
reading 0dB.
With a stereo line input playing and assigned to PGM, AUD and TEL,
verify that audio is indeed present at these respective console outputs.
Note again that if a console output is being used to feed consumer type
(–10dBu level equipment), the outgoing signal may be too hot for the
receiving unit. In this case, turn down the external machine's input gain
trims, or, if they are not available, you may wish to install a pad circuit
between the console output and the outboard unit (see page A-3 for a
suggested circuit). Be aware also of the proper way to hook up unbalanced
equipment to the console's balanced outputs (see page 1-8).
