DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410.
MIC SPLITTER APPLICATION EXAMPLE
In the mic splitter example application, we have supposed a live show, in which we should
give signal to a recording truck. For explanation simplicity, we supposed a reduced set-up about
four microphones and a DA-410 only. Normal set-ups will need 32 or more microphone inputs
corresponding to 8 or more DA-410 units.
The F.O.H. (Front of house) console is connected directly to the stage box, to give phantom
powering to the microphones requiring it. The other output of the stage box (both are paralleled) is
connected to the DA-410 inputs. In this configuration the inputs are configured in MIC mode
operation, regardless of the input signal level. See previous related paragraphs. DA-410 outputs
drives separately the Monitor and remote recording consoles avoiding ground loops, interference,
and accidental signal drop-outs conflicts.
The use of input (IT-DA) and output (OT-DA) transformers is recommended in order to provide
a galvanic isolation within all three consoles assuring also an increasing performance in
interference rejection on large cable runs normally found in these set-ups.
