Rackmount Installation
1. Remove the amplifie’s four feet from the bottom of the chassis.
2. Attach the included rack-mount ears to the front sides of the amplifier chassis.
3. Securely mount the amplifier into the 19” equipment rack. The amplifier will
occupy 1U of rack space.
4. For best results leave 1U of room for ventilation between amplifiers.
Ventilation
Be sure that the amplifier is in a well-ventilated area that provides adequate cooling.
If your installation lacks good air flow, such as cabinets or wall-mounted racks, it may
be necessary to create some ventilation to air outside the cabinet or rack.
Do not block ventilation holes, or impede air flow by placing objects on or around
the amplifier. Do not place the amplifier on carpeting or any similar material.
Do not install the amplifier near a source of heat, or in an extremely humid or wet location.
Positioning
If your D-501 is not rack mounted, position it with all feet resting on a solid level surface.
Make sure that there is a minimum of 2” of free air space above the amplifier and 2”
on each side for proper ventilation. Allow a minimum of 3” of depth behind unit to
accommodate cables and connectors.
CAUTION: All connections and switching must be done with the amplifie’s power switch
positioned to ‘Off’. Connect the power cord last to be sure that the amplifier is off during
all of your connections and set up.
Interconnect Cables
When connecting the D-501 amplifier to your Actuators using the speaker level connections,
use a high quality speaker cable. It is recommended that you keep the length of cable as short
as possible to avoid any potential external interference problems. When connecting the D-500
amplifier to your actuators, use speaker cable that is at least 18-gauge. Be very careful
to avoid any loose or frayed strands that could result in a short, causing a dangerous condition
and possible damage to your unit. Cables of extremely large size are typically not required.
Extremely large wire may not properly fit in thebinding posts, resulting in a poor connection and
possible short circuits.
Caution! The power cord should be routed in such a way that it will not be walked on, pinched
or compressed in any way that could result in damaging the insulation or wire.
