2. Outputs
The output from the DACS MicAmp is a fully floating electronically balanced
output designed to drive down long 600 lines. It will run balanced or unbalanced,
and can provide signal levels in excess of +22dBm when running balanced or
unbalanced. To run unbalanced connect either pin 2 or pin 3 to 0V. NB The
output will not run unbalanced satisfactorily if one leg is left floating and not
connected to 0V.
3. & 4. Inputs
The DACS MicAmp has two microphone inputs, one for phantom powered (48V)
microphones and one for non phantom powered microphones. The non-phantom
powered input by-passes the input capacitors, and avoids the signal degradation
caused to low microphone voltages by switching the signal. The microphone
amplifier stage has a minimum gain of 20dB. Before connecting microphones,
ensure that the MicAmp's gain is set to 20dB, and that any loudspeakers are
turned down.
