and to allow easier access for servicing. Allowing an inch of space behind the
amplifier for connections, the rack requires a total depth of seven inches. A cooling
fan is recommended when the rack is enclosed and any of the following conditions
exists:
9
The combined rated output power of all the equipment exceeds 250 watts
RMS; or
9
The input from the AC power line exceeds 500 watts; or
9
Restricted air flow in the rack may create extreme heat.
Important:
Failure to observe the preceding precautions could result in overheating that could
damage the equipment or create a fire hazard.
Rack-Mounting
The DAX Series amplifiers are designed to be mounted into a standard 19-inch
rack. #10 "U" nuts (AB1889) and two kinds of mounting screws are supplied with
each amplifier.
1.
If the rack's holes are untapped, select the #10 thread-forming screws
(WA102). Push the #10 "U" nuts, their flat side facing outward, onto the
proper holes in the rack. (you may have to leave the "U" nuts off if the holes
are extruded).
2.
If the rack's holes are tapped, select the #10 machine screws (WA202).
Turret-Mounting (DAX6O only)
The rack-mounting procedures can be used to install the DAX6O in a Rauland
Control Turret. However, if the turret’s internal rails are used and the amplifier is
oriented with its front panel facing the rear of the turret, an optional MK1O
Mounting Kit will be needed. This special-order kit must be installed by factory-
trained personnel.
Important:
9
Do not connect AC power to the amplifier until all of the necessary input and
output connections have been completed.
9
Do not disconnect the third wire on the power plug. This wire grounds the
amplifier's chassis to prevent a possible shock hazard. If an adapter is used to
connect the plug to a two-prong socket, make sure that the amplifier’s chassis
is connected to a proven earth ground.
