4.1 SHORT OVERVIEW OF TRIPLE LINE MODULE FUNCTIONS
Microphone input: Electronically balanced
Impedance: 2 kOhm
Level: From -70 dBu microphone input to 0 dBu
Connectors: XLR female, Pin 1 = ground. Pin 2 = in phase. Pin 3 = out of phase
48 Volt phantom: Jumper enabled/disabled, (see chapter 12)
Mic High pass filter: At 80 Hz internally set by a jumper, (see chapter 12)
REMOTE: (Only when programmed)
Remote control of the channels CUE and/or Cough/Communication
'Channel-on' light signaling. Connection by way of a stereo jack
Tip = 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.
Ring = 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.
Sleeve = ground.
A-Input and B-Input: 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.
Connector is Jack: 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.
NOTE: By adding an optional plug-in stereo R.I.A.A. pre-amp, the B input is able to accept M.D.
phono pick-ups. See (see chapter 12)!
START: Stereo jack plug
Tip = Center contact
Ring = Normally open
Sleeve = Normally close
Maximum voltage/current that can be handled=24 volt at 50mA
NOTE: Polarity is not important with reed relays!
DO NOT CONNECT 115/230VOLT AC TO THIS CONNECTOR!!!
Pulse or Continuous Signal:
Software programmable between active or not and between pulse or
