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

continue
