5.1 SHORT OVERVIEW OF TRIPLE DIG INPUT 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.

Dig. A-Input: transformer balanced 110ohm AES3 input on XLR

Data: 24bit, 32..96kHz. Dynamic Range, S/N: 100dB

Input level: -9dBFS = 0dBU preGain (gain +/-20dB)

Dig. B-Input: unbalanced 75ohm S/P-dif input on Cinch (black).

Data: 24bit, 32..96kHz. Dynamic Range, S/N: 100dB

Input level: -9dBFS = 0dBU preGain (gain +/-20dB)

Digital output: AES3: transformer balanced 110ohm on XLR

S/P-dif: 75ohm, unbalanced on Cinch (red).

Data: 24bit, 32..96kHz. Dynamic Range, S/N: 100dB

The digital output frame clock (sample rate) can be setup in two different ways

by internal jumper setting (see also chapter 12).

1. Fixed. Output Frame Clock (sample rate) is always 44.1kHz

2. PLL. Output Frame Clock (sample rate) is identical to the clock signal of

the digital input.

Jumper selectable SUB or PROG output.

Output level: adjustable (normal 0dBu = -9dBFS)

Connector is Jack: LINE A = AES3 balanced wired to a female XLR connector

Pin 2 is in phase, Pin3 is out of phase and pin1 is ground

LINE B = S/P-dif unbalanced on Cinch connectors.

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
