al space be left above and below the amplifier to prevent hum from being intro-
duced into adjacent equipment (such as preamplifiers), to provide additional
ventilation,
and to allow easier access for servicing. Adding an inch of space
behind the amplifier for connections,
the rack should have a total depth of
seven inches. A cooling fan is recommended when the rack is enclosed and any
of the following conditions obtains:
(a) The combined rated output power of all the equipment exceeds 250 watts
RMS; OR
(b) The input from the AC power line exceeds 500 watts; OR
(c) Restricted air flow in the rack may create extreme heat.
CAUTION
FAILURE TO OBSERVE THE PRECEDING PRECAUTIONS COULD RESULT IN OVERHEATING
THAT COULD DAMAGE THE EQUIPMENT OR CREATE A FIRE HAZARD.
Rack-Mounting
The DAK Series amplifiers are designed to be mounted into a standard 19-
inch rack. #lO "U" nuts (AB1889) and two kinds of mounting screws are supplied
with each amplifier.
A. If the rack's holes are untapped,
select the # 1 0 thread-forming screws
(WA102).
Push the #l0 "U" nuts,

B. If the rack's holes are tapped, select the # 1 0 machine screws (WA202).
Turret-Mounting (DAX60 only)
The rack-mounting procedures can be used to install the
Control Turret. However,
if the turret's internal rails are
DAX60 in a Rauland
used and the am-
plifier is oriented with its front panel facing the rear of the turret, an
optional MKlO Mounting Kit will be needed. This special-order kit must be
installed by the factory.
WARNING
DO NOT CONNECT AC POWER TO THE AMPLIFIER UNTIL ALL OF THE NECESSARY INPUT
AND OUTPUT CONNECTIONS HAVE BEEN COMPLETED.
