Cooling
WARNING: AN AMPLIFIER’S PERFORMANCE MAY DETERIORATE IF IT OVERHEATS. TEMPERATURE AND
VENTILATION ARE KEY FACTORS IN PROPER OPERATION. NOT ONLY SHOULD YOU PROVIDE ENOUGH
SPACE AROUND THE UNIT, BUT ALSO ENSURE THAT AIR CAN FLOW FREELY AND ESCAPE FROM THE
AMPLIFIER’S SURROUNDINGS.
Placement
During normal home operation, the heatsinks of the AT6012 will become warm. However, there are instances during
high-level playback into low impedance speakers when the heatsinks will become much warmer than usual. To ensure
the amplifier’s trouble-free operation, it is necessary to provide adequate ventilation for the heatsinks. The AT6012
should be kept away from external sources of heat such as radiators and hot-air ducts. The AT6012 should never be
placed with other heat-producing components in a cabinet or enclosure lacking free air flow.
If you must mount the AT6012 in an enclosed cabinet, it is recommended that the rear panel of the cabinet be provided
with ventilation openings at the top and bottom to allow air to circulate freely in the cabinet. The top and bottom
panels of the amplifier’s chassis have been engineered with vents to allow the necessary cooling of the internal
components. Do not obstruct these openings in any way.
Do not stack other components on top of the AT6012. This is critical if you are using low impedance loudspeakers
which are difficult to drive, or if you constantly play your system at high levels.
Rack Mounting
Your amplifier may be mounted in a standard 19-inch rack by using the optional Rack Mount Panel.
CAUTION: THE RACK MOUNT PANEL CANNOT SUPPORT THE WEIGHT OF YOUR AMPLIFIER.
BE SURE TO MOUNT THE UNIT ON A STRONG, WELL-SUPPORTED SHELF.
