DDR-16/32 Installation & Operating Guide
Document # 9301H85300 Ver. 0.91
NOTE:
Technical adjustments should only be performed by a qualified theater
technician. The appendices provide detailed information for the theater technician.
1.0 Installation
1.1 Unpacking System Components
The packaging is designed to handle normal shipping and handling. Upon receipt of shipment, check for
signs of damage before opening and report all damage to the carrier. All shipments made from Datasat
Digital Entertainment are customer responsibility once they leave our premises.
Before installation begins, we suggest that a complete inventory be taken to minimize problems or
questions during installation. Additionally, save all packing material until installation is complete in the
unlikely event that a component(s) requires return to the factory. Use the packing slip that came with
your unit to verify received inventory.
1.2 Chassis Rack Mounting and Connection
The DDR-16/32 chassis requires 2U of standard rack space for proper mounting.
Caution:
Because power line surges can damage the DDR-16/32, we require the use of a
properly functioning computer-grade surge /spike suppressor. We also recommend using an
uninterruptible power supply (UPS).
Device Disconnect:
The power outlet shall be installed near the equipment and shall be
easily accessible, in order to quickly disconnect power.
1.
Install the DDR-16/32 into the audio rack, securing it properly with rack screws.
2.
Connect the DDR-16/32 to other equipment (see appendix: A Connector Pinouts).
3.
Connect the supplied power cable between the DDR-16/32 unit and the AC mains source.
1.2.1 Rack Mount Recommendations
Follow these recommendations if the DDR-16/32 unit will be installed in a closed or multi-unit rack
assembly.
Determine the maximum and ambient temperatures within the rack, since they may be greater
than the maximum and ambient temperatures in the room. The maximum temperature for the
equipment in a closed or multi-rack assembly is 40°C (104F°)
Ensure adequate airflow for cooling purposes on all sides of rack-mounted equipment.
Check nameplate ratings to ensure there is no overloading of supply circuits that could have
an effect on over-current protection and supply wiring.
Maintain reliable grounding of the equipment. Give particular attention to supply connections
when connecting to power strips, rather than direct connections to the branch circuit.
Using a properly functioning quality surge protector is required to protect the unit. Using an
uninterruptible power supply (UPS) is also recommended.
1.2.2 Power Supply
The DDR-16/32 power supply automatically switches itself to accommodate AC input between 110
VAC and 220 VAC.
