DD-8 Power Ampliers
Operation Manual6
Installation Considerations
To ensure optimal performance, pay particular attention to the instructions below and to other
precautions that appear throughout this user guide.
DO install the DD-8 on a solid, at, level surface such as a table or shelf. The DD-8 can also be installed
in a standard 19-inch equipment rack using the rack-mount ears included with the product.
DO select a dry, well-ventilated location out of direct sunlight.
DO NOT install the DD-8 on a surface that is unstable or unable to support all four feet.
DO NOT expose the DD-8 to high temperatures, humidity, steam, smoke, dampness or excessive dust.
Avoid installing the amplier near radiators and other heat-producing appliances.
DO NOT install the DD-8 near unshielded TV or FM antennas, cable TV decoders, or other RF-emitting
devices that might cause interference.
DO NOT place the DD-8 on a thick rug or carpet, or cover the ventilation holes in the chassis, as this
might prevent proper cooling.
DO NOT place the DD-8 on a windowsill or any location exposed to direct sunlight.
Installation Options
The DD-8 is shipped without feet or rack ears installed. Both are included in the packaging and you
will need to install one or the other depending upon the type of installation/mounting required. If the
DD-8 is to be placed on a shelf or audio furniture, you will need to attach the four plastic feet to the
bottom of the amplier using a #2 Philips screwdriver and the included hardware. (See Figure 1) If the
DD-8 is be mounted into an equipment rack, you will need to attach the two metal rack ears to the left
and right sides of the amplier using the included T-10 Torx key. (See Figure 2)
NOTE: If multiple DD-8’s are to be rack mounted together, it is acceptable to “at stack”
them one atop the other in adjacent rack spaces without additional ventilation spaces
left in between them. However, in some installations or in heavy usage scenarios where
multiple channels are consistently driven at high outputs for long periods of time, it might
be necessary to leave one empty rack space between the ampliers in order to assist with
heat dissipation and prevent thermal protection due to overheating.
