GENERAL NOTES
LOCATION & VENTILATION
The Langevin 150 Watt Solid State Amplifier must be installed in a stable location with ample
ventilation. The unit is designed as a standard 2 u rack mount unit. Be certain to allow for ample
ventilation around the unit. Do not place directly above other rack mount equipment that dissipates
a significant amound of heat. We also recommend that the amplifier if driven by a preamplifier be
placed at least 10 inches apart. Do not place amplifiers directly on high pile carpet or any other
surface that will prevent proper ventilation.
WATER & MOISTURE
As with any electrical equipment, this amplifier should not be used near water or moisture. If liquid
enters the amplifier, it must be immediately returned to your dealer for servicing.
SERVICING
The user should not attempt to service the amplifier beyond that described in the owner's manual.
Refer all servicing other than biasing and tube replacement to Manley Laboratories
