Model 5422A

 

DANTE INTERCOM AUDIO ENGINE

Summing Bus

This operating mode allows Dante receiver (input) audio signals to be summed (combined, mixed, or added). 

This mode can be considered as implementing a “unity” gain mixing amplifier or “mix bus” function. The resulting 

output signal is provided on multiple Dante transmitter (output) channels. For flexibility the input and output levels 

can be adjusted over a ±20 dB range using the receiver (input) and transmitter (output) functions.

This mode is identical to the Summing Bus w/Auto Mix operating mode with the exception that the Auto Mix 

function is not active.
