Power Supply Polarity
Note that polarity of the plug found on the DC power supply needs to match
that of the original power supply that came with your Aviom equipment.
Aviom products use a center positive power supply. The outer contact is
negative, the inner contact is positive. (See the diagram above.)
Installing in an Equipment Rack
The AN‑16/i Input Module is designed to be installed in a standard 19‑inch
audio equipment rack. This design is both for easy transportation of the unit
and for protection. Each unit takes up one standard rack space (19 inches
wide by 1.75 inches high).
The rack ears on each side of the device are designed to support the weight
of the AN‑16/i without additional hardware. Each rack ear contains holes for
two screws per side. Always support the unit with all four screws.
To rack mount the AN‑16/i, position it in the equipment rack at the desired
location. Use standard rack‑mounting screws (10‑32 size) to attach the unit to
your rack hardware. Tighten all four screws firmly, but avoid overtightening.
You may want to use non‑metallic washers between the rack‑mounting
screws and the device’s finished surface to avoid marring the painted finish
on your Aviom products.
Always allow adequate ventilation for devices mounted in equipment
racks. Avoid placing your Pro16 product directly above or below other rack‑
mounted devices that produce high levels of heat, such as power amps.
