Standard Crystal Vision module 266mm
x 100mm
Weight: 200g
Power consumption: 6.25 Watts
AUDIO INPUTS
2 x 20/24 bit stereo pairs. AES3 110ohm (balanced)
D Type, or AES3-id (unbalanced) 75ohm BNC
Set by on-board jumper links to 75ohm, 110ohm
or high impedance for multiple units on a single
feed
32, 44.1 and 48kHz (Clock regeneration for 48kHz)
AUDIO OUTPUTS
Two analogue stereo pairs 24 bit quantising
D to As
Low impedance balanced (66ohm) output
Two outputs of each
Level range: 0dBFS = +28dBu max; 0dBFS = +12dBu
min
Factory set default: 0dBFS = +18dBu and +24dBu
by on-board link
Signal to noise: Weighted better than -98dB
Total harmonic distortion (THD): <.0025%
at +18dBu/+24dBu (48kHz crystal mode)
Interchannel crosstalk: <-110dB
Frequency response: +/- 0.2dB 20Hz to 20kHz
GPI INPUT LEVELS
Connect to ground active
Inactive high impedance or 3 to 48 volts
Input current 50uA
GPI OUTPUT LEVELS
CMOS levels
Max current 20mA
GPI INPUTS
48kHz crystal or auto frequency select
Swap channels 1 and 2, single stereo (all outputs
from AES input 1), give GPI error on sustained
silence
GPI OUTPUTS
Loss of reference or sustained silence (1 output
for each analogue stereo input)
Set period of silence before indication from
1.5 to 120 seconds in 8 second increments
