A note about Digital Out
When using the Digital Out, make sure the input device is set to the same sample frequency as
the RS20i and that its clock source is set to input. Sample rate choices are 48kHz, 96kHz, and
192kHz. Select the highest rate supported.
2.5 Mounting and Connection
The RS20i may be mounted in a standard equipment rack or placed on a desktop.
Warning: Before powering on the RS20i for the first time, verify that the correct input
voltage has been selected at the rear panel power entry module. Incorrect input voltage
setting will damage the RS20i. See section 2.5.4.
Caution: Because power line surges can damage the RS20i, we require the use of a
properly functioning computer-grade surge /spike suppressor. We also recommend using
an uninterruptible power supply (UPS) with minimum 200 VA.
1. Install rack ears (if rack mounting) on the RS20i. These are included in the RS20i packing
kit.
2. Install the RS20i into the audio rack, or place on desktop.
3. Connect the RS20i to other equipment (see appendices: A Connector Pin-outs, B Interface
Wiring Diagrams, and C RS20i Wiring and Block Diagrams).
4. Connect the supplied power cable between the RS20i unit and the AC mains source.
2.5.1 Rack/Enclosure Requirements
Follow these recommendations if the RS20i unit will be installed in a closed or multi-unit rack/enclosure
assembly.
ƒ
Elevated Operating Ambient Temperature – Determine the operating ambient temperature
within the rack or enclosure, since this may be greater than the ambient temperature in the
room. The maximum ambient temperature for the equipment in a closed or multi-rack
assembly is 40°C (104F°)
ƒ
Reduced Air Flow – Ensure adequate airflow for cooling purposes on all sides of the
equipment. Make sure that the ventilation fan is not blocked.
ƒ
Mechanical Loading – Mounting of the equipment in a rack should be such that a hazardous
condition is not caused due to uneven mechanical loading.
ƒ
Circuit Overloading – Consideration should be given to the connection of the equipment to
the supply circuit and the effect that overloading of the circuits might have on over-current
protection and supply wiring. Appropriate consideration of equipment nameplate ratings
should be used when addressing this concern.
ƒ
Reliable Earthing – 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.
ƒ
Surge Protection – Using a properly functioning quality surge protector is required to protect
the unit. Using an uninterruptible power supply is also recommended.
