Output channels

Output signals are sent to the analog output connectors (26) from the stereo bus.

Adjusting analog outputs

Use the line output VOLUME knobs (20) to adjust the output levels so that the analog output PEAK indicators (18) do not light.

NOTE

Mono signals will be output if MONO - STEREO (27) switches are set to MONO.

Using the talkover function

The signal levels from the stereo bus can be automatically attenuated when the sound levels of connected mics exceed the level set by the TALKOVER THRESHOLD knob (30), making the sound from the mics easier to hear.

This only attenuates the levels of output channels to which that mic is assigned.

Examples

If MIC 2 OUTPUT SELECT switch 3 (③) is on while switch 1 and 2 are off, when MIC 2 exceeds the set level, the other inputs to output channel 3 will be automatically attenuated before the sound of MIC 2 is mixed in and output. Output channels 1 and 2 will not be attenuated and the sound of MIC 2 will not be mixed into them.

1. Enable the talkover function for the desired mic input channels by setting their TALKOVER switches (38) to ON.
2. Select the output channels that will be affected by the talkover function by setting the mic input OUTPUT SELECT switches (③).
3. Use the TALKOVER THRESHOLD knob (③0) to set the input sensitivity (threshold level) for the talkover function.
