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
