StudioTech 233 manual Talkback 2 Button Function, Main Output Source, Sidetone Mode

Talkback 2 Button Function

Switch SW3-6 configures the overall operation of the button associated with talkback 2.

Figure 12. Talkback 2 function mode settings

Two modes are available:

•Disabled: In this mode the talkback 2 button is disabled. The talkback 2 line- level output and, if configured, talkback to intercom pin 3 function, will never be active. An exception is if the auxiliary relay is configured to follow the status of the talkback 2 button. In this case the talkback 2 button will only control the relay.

•Enabled: In this mode the talkback 2 button will operate normally. Whenever the button is active the line-level output and, if configured, the talkback to inter- com pin 3 function, will be active.

Main Output Source

Switch SW3-7 is used to select which audio source is routed to the main output. The choices are the output of the micro- phone preamplifier or the output of the compressor circuit. For most on-air ap- plications the output of the microphone preamplifier is the desired source. This will provide the most natural audio quality with the potential for a large amount

of dynamic range.

In some applications it may be desirable for the output of the compressor circuit to be routed to the main output. Appropriate

applications could include on-air broad- cast situations where nonprofessional talent is present. Controlling the dynamic range of the audio signals on the main output can limit the chance of cable cross- talk and equipment overload. Another typical application where using the output of the compressor would be appropriate when the Model 233’s system mode is selected for production. In this case the main output would be used as an addi- tional talkback output and dynamic range control would be beneficial.

Sidetone Mode

Switch SW3-8 configures the way the sidetone function operates.

Two modes are available:

•Main Button: In this mode the sidetone function will only be active when the main output is active.

•Main and Talkback Buttons: In this mode the sidetone function will be active when- ever the main, talkback 1, or talkback 2 outputs are active.
