Installation and Mounting

All power amplifiers are 2-rack space units that can mount in a standard 19-

inch rack. Four front panel mounting holes are provided. Rear mounting

ears give additional support, they are especially important in mobile sound

system. Because of the cables and connectors on the rear panel, a right-

angle of offset screwdriver or hex key will make it easier to fasten the rear

mounting ears to the rails.

Thermal Protection

If the heat sink temperature reaches an abnormally high

temperature, the amplifier will protect itself by disconnecting

loudspeakers and shutting down until sufficiently cooled.

Short Circuit

If an output is shorted ( i, e.. defective speakers or crossed speaker wires)

the ZSP and thermal protection circuits will automatically protect the

amplifier. The ZSP circuit senses the short circuit as an extremely stressful

load condition and attenuates the signal, protecting the channel's output

transistors from over current stress. If the short circuit remains, the load will

be disconnected by the thermal protection circuit.

DC Voltage Protection

If an amplifier channel detects DC voltage at its output terminals, the output

relay will immediately open to prevent loudspeaker damage.

Connecting Power/Circuit Size Requirements

Damage caused by connecting the amplifier to improper AC voltage is not

covered by any warranty. Note: Always turn off and disconnect the amplifier

from main voltage before making audio connections, and as an extra

precaution, have the volume controls turned down during power-up.

Cooling Requirements

The power amplifiers use a convection cooling system to maintain an even

operating temperature. Air enters through the vents on each side and the

bottom of the amplifier chassis and exits through the sides and top of the

chassis. Make sure that there is enough space around the sides of

the amp to allow the heated air to exit. If the amp is rack-mounted, do not

use doors unless you have forced air cooling. Note: Whatever type of rack

you are using, make sure that the heated air can escape freely, and that

there is no resistance to the intake of cool air through the chassis.
