Installation Recommendations
Mounting
The unit is designed to install into a standard 19" rack mounted at eye
level for best visual observation of the monitor screens.
Heat Dissipation
Heat dissipated by the speaker amps is conducted directly to the sides
of the chassis; no special considerations for cooling are necessary as
long as the ambient temperature inside the rack area does not exceed
approximately 40°C (104°F).
AC Power
The unit's AC mains connection is via a standard IEC inlet, with safety
ground connected directly to the unit's chassis. The universal AC input
(100-240VAC, 50/60Hz) switching power supply is a self-resetting
sealed type, with automatic over-voltage and over-current shutdown.
There is no user-replaceable fuse in either the primary or secondary
circuit.
Sympathetic Vibration
Sympathetic vibration from other equipment (cables, etc.), in the rack
may be serious enough to interfere with the unit's sound quality out in
the listening area. The use of thin card stock and/or felt or foam
weather-stripping type materials between adjacent vibrating surfaces,
or tying up loose cables, etc., may be required to stop vibrations
external to the unit.
Mechanical Bracing
The chassis is securely attached to the front panel at eight points along
its surface, not just at the four corners of the chassis ears. This feature
will reduce or eliminate rear bracing requirements in many mobile/
portable applications. The weight of internal components is distributed
fairly evenly around the unit.
