Electronically balanced
2 kOhm
From -70 dBu microphone input to 0 dBu
XLR female, Pin 1 = ground. Pin 2 = in phase. Pin 3 = out of phase
Jumper enabled/disabled, (see chapter 12)
At 80 Hz internally set by a jumper, (see chapter 12)
(Only when programmed)
Remote control of the channels CUE and/or Cough/Communication
'Channel-on' light signaling. Connection by way of a stereo jack
Positive supply voltage, current limited at 6 mA when the channel is 'active
(fader up)'. A direct connection to a LED is possible between tip and sleeve.
When momentarily connected to ground, the channel will be muted and CUE
is activated creating a Cough/Communication function when the channel is in
the Mic mode. CUE can be normally activated when in LINE mode.
ground.
The input impedance for both 'A' and 'B' are >10 kOhm, and the maximum
sensitivity ranges from -20 dBu to +20 dBu. The signal to noise ratio is -90 dBr
(R.I.A.A. = -70 dBr). Nominal level of the A input is +4dBu and for the B input
0dBu.
LINE A = balanced wired to a female XLR connector Pin 2 is in phase,
Pin3 is out of phase and pin1 is ground
LINE B = unbalanced on Cinch connectors.
Stereo jack plug
Tip = Center contact
Ring = Normally open
Sleeve = Normally close
Maximum voltage/current that can be handled=24 volt at 50mA
