Wall mounting option
INSTALLATION OPTIONS
Rack Mounting
The rack mounting ears support either one or two amps in a single rack space.
.
To install one amplifier in a rack space, use the long ear and one of the wall-
mount brackets. The unit can be mounted either to the left or right side of the
rack space.
Single unit rack mounting option
For two units in one rack space, use the flat plate to support and connect them,
and use one wall-mount bracket on each outer side of the units.
When using the two-unit mounting option, the small side ventilation slots on
the amps will be next to one another in the middle of the rack space. To avoid
overheating situations, make sure the copious top panel ventilation holes are
not blocked.
Dual unit rack mounting option
