Installation
The 1073s and 1084s are available as stand-alone modules, or in a choice of two housings.
The 3U rack houses two modules mounted horizontally in a 19” rack-mounting unit.
The 5U rack houses eight modules mounted vertically in a 19” rack-mounting unit.
Both have rear panels with XLRs for transformer balanced I/O.
The 3U rack rear panel has a fused, voltage selector IEC mains input connector. The 5U rack has a
free standing AC supply with a fused, voltage selector IEC mains input connector and connects to
the rack via a connector and a 1.5 meter cable.
Modules of any combination can be fitted into a rack unit.
Additional Information
*Rack Mount Instructions *_
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore, consideration should
be given to installing the equipment in an environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.
D) 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 overcurrent protection and supply
wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this
concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connections to the
branch circuit (e.g. use of power strips).
Recommended Tma = 50 deg C
