Talkback and Oscillator
Talkback Connections
The C300HD console contains a built-in talkback microphone and amplifier. In addition, a second input is available for
connection to an external dynamic microphone. This input is mixed with the internal T/B mic and the combined signal is
available via an XLR connector on the audio interface panel beneath the console. This output signal should be connected
to an analogue input circuit in the Centuri processor. The circuit chosen can then be assigned as the talkback source via
the console’s routing.
The gain of each mic signal can be independently adjusted. Access to the trim controls is from beneath the console on the
console interface panel.
The external mic input is via a 3-pin XLR female labelled ‘Ext T/B Mic In’.
The mixed T/B output is via a 3-pin XLR Male labelled ‘Talkback Output’.
Oscillator Connections
The C300HD includes an inbuilt software oscillator capable of generating a range of sinusoidal frequencies as well as pink
noise. This signal can be assigned to any relevant output without additional cabling.
Alternatively, an external oscillator (either analogue or digital, mono or stereo) may be used. In this instance one or two
circuits should be allocated on an input card, they can then be assigned as the oscillator source.
Refer to Appendix C for connector pinouts.
