INSTALLATION MANUAL
16. SR-1000 INPUT AND OUTPUT
16.6.1.1. Connections Requirements
Sr. No.
Device Type
Description
1
Connection to analog Amplifier
*
Connect the
8 channel Analog unbal. output
of the
AIB-2000 to the inputs of analog Amplifiers/Crossovers
using appropriate line level audio cables and connectors.
2
Connection to Hi/Vi-N devices
AES output pair
11 and 12
on the SR-1000 carries the
Hi and Vi-N channels respectively (assuming
DCP’s
follow the 16 channels ISDCF recommended channel
order).
The
AES pair 11/12
is available on the
RJ45 Connector
labeled
A-bot
on the IMB and can be connected to the
Hi/Vi-N device either directly or via a 2 channel D/A
converter depending on whether the Hi/Vi-N device
accepts AES3 or analog inputs.
Appropriate cable and connectors should be chosen,
keeping in mind the connectors used on the Hi/Vi-N
device and 2 channel D/A converter (if used).
3
Connection to 4D systems
AES output pair 15/16
on the SR-1000 carries the LTC
signal used to sync 4D systems like ScreenX, 4DX and
MX4D to the SR-1000.
The ‘
Enable LTC Output on Channel 15/16’
option must
be checked under
Audio
→
Configuration
sub-tab.
The
AES pair 15/16
is available on the
RJ45 Connector
labeled
A-bot
on the IMB and can be connected to the
LTC input on the 4D System.
Appropriate cable and connectors should be chosen
keeping in mind the connector used on the 4D system.
Please Note
: LTC is not an AES3 audio signal although
it uses two pins (7 & 8) of the
A-bot
connector on the
SR-1000 which otherwise carries AES3 audio. When
enable
‘
Enable LTC Output on Channel 15/16
’
option is
checked; pins 7 & 8 carry the LTC signal. As a result, AES3
channels 15 & 16 are not available when LTC is enabled.
Pins 7 & 8 of the
A-bot
connector must be wired directly to
the LTC inputs of the external 4D system using a suitable
cable (please check with the 4D system manufacturer
for details).
A break out cable may be required to allow pins 7 & 8 to be
connected to an external 4D system while allowing pings
1-6 which carry AES3 channels 9-14, to be connected to
the audio system.
