Introduction
1 Introduction
ADP 310 is a processor for analogue or 24-bit 48 kHz digital audio.
Audio signals are input and output as either two analogue stereo pairs or four AES
stereo pairs.
Audio signals can be gain controlled by +/- 18dB, delayed by up to 400mS, inverted,
muted, stereo to mono converted and shuffled. Asynchronous AES signals are
automatically resampled if not Dolby E encoded.
There are two slots for analogue or digital I/O piggybacks of which there are three
types: 3G-AIP2, 3G-AOP2 and DIOP4. The 3G-AIP2 piggyback has four analogue
inputs; 3G-AOP2 has four analogue outputs; DIOP4 has four stereo AES pairs.The
front slot (nearest handle) is for audio inputs and can be fitted with a 3G-AIP2 or
DIOP4 piggyback. The rear slot (nearest edge connector) is for audio outputs and can
be fitted with a 3G-AOP2 or DIOP4 piggyback. It is not possible to mix analogue and
digital signals, so an ADP 310 will be fitted with either a 3G-AIP2 + 3G-AOP2
combination or two DIOP4.
The main features are as follows:
•
Optimise the audio:
each channel has individual gain control and
stereo to mono conversion. The audio level can be increased or
decreased to match the rest of the system: each mono audio channel
offers individual gain control, adjustable b18dB and -18dB in
0.1dB steps. Audio channels can be muted and stereo pairs
converted to mono. Audio channels can be delayed by up to 400mS.
Dolby E signals automatically bypass all audio processing.
•
Audio resampling:
Asynchronous 48 KHz AES signals automatically
resampled unless Dolby E encoded.
•
Control
of ADP 310 is by VisionWeb web browser software. Control
can additionally be from an active front panel on the frame, a remote
panel or via SNMP. Card edge control was also available prior to
2018.
•
GPI control
of configuration set-ups and status alarms.
•
Supports the following rear module connectors:
RM47, RM74.
•
Compatible
with Crystal Vision standard frames available in 2U, 1U
and desk top box.
