MECHANICAL
Standard Crystal Vision module 266mm x 100mm
Weight: 200g
Power consumption: 7.5 Watts

AUDIO INPUTS
Two analogue stereo inputs
High impedance input (>2 kohm)
Level range: 0dBFS = +28dBu max; 0dBFS = +12dBu min
Factory set default: 0dBFS = +18dBu and +24dBu by on-board link
Reference input: Analogue video Black & Burst or mixed syncs for 48kHz sampling. AES reference or word clock for 32kHz, 44.1kHz or 48kHz sampling
48kHz clock will be regenerated, 32kHz and 44.1kHz taken directly from reference

AUDIO OUTPUTS
Maximum of four 24 bit stereo outputs per channel (two outputs with frame rear modules RM14 and RM21, three with RM13 and four with RM03, RM11 and 'easywire' RM35)
AES3 110 ohm (balanced) D-Type or AES3-id 75 ohm (unbalanced) BNC. Order version required by selecting OPAES-110 or OPAES-75 output module
Reference rear module loop-through available on RM13 and RM14 - loop does not need ADCA412 to be fitted as rear module has passive circuitry required
Can convert to single channel operation if extra outputs from single input required
Works with any sampling rates between 30kHz and 50kHz, usually 32, 44.1 and 48kHz sampling
Signal to noise: Weighted better than -98dB
Total Harmonic Distortion (THD): <.005% at +18dBu/+24dBu with 48kHz sampling
Interchannel crosstalk: <-110dB
Frequency response: +/- 0.1dB 20Hz to 20kHz

DELAY THROUGH BOARD
100ns

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
Mono input repeat on stereo outputs
Swap channels 1 and 2
Reference select (two GPIs select video, AES or word clock)

GPI OUTPUTS
Loss of reference or sustained silence (one output for each analogue stereo input)
Set period of silence before indication from 1.5 to 120 seconds in 8 second increments

LED INDICATION OF:
Power supplies
Clock reference
Audio silent

LOCAL CONTROL
Options and silence indication delay set by switches at board edge

REMOTE CONTROL
RS422/485
19200 baud, 8 bits, 1 stop no parity
Control from frame active panel and remote panel
Statesman allows control from any PC on a network
SNMP monitoring and control available as a frame option
