Yamaha P-2200/2201 - Manual (Page 22)

INSTALLATION AND DETAILED
OPERATION
PHYSICAL MOUNTING
Shelf Mounting
The P-2200 can be used on any surface, so long as
there is adequate ventilation. Do not remove the
P-2200's feet, since this would prevent air flow below
the amplifier.
Permanent Installation Rack Mounting
Mount the P-2200 in any standard 19" electronic
equipment rack as shown to the right. Leave adequate
space between the P-2200 and other devices in the rack
for ventilation, and for expected cabling. Cooling fans
may be required when the P-2200 must produce
extremely high average power output, or when it is
located in a high temperature environment, such as a
closed outdoor building in direct sunlight.
Rack Mounting for Portable Usage
Road cases must be durable enough to survive heavy
cartage, and airline travel. Brace the rear of the P-2200,
and if the road case is small and ventilation is con-
stricted, install cooling fans. One possible design is
shown in Figure 35.
