DESCRIPTION

The 9441A Anniversary Series power Am-
plifier delivers 75 watts continuous average
power into 8 ohms or 100 watts into 4 ohms
over the full audio bandwidth.

Convection cooling and associated control
systems are optimized together for maximum
performance and protection. In typical fixed
installations, this provides increased long term
reliability.

The universal power transformer is as large
as those often used in amplifiers with twice the
power rating.

Each channel is protected against over-tem-
perature conditions, radio frequency interference
and shorted outputs.

The load is protected against startup/shut-
down transients, subsonic signals, low ac line
voltage, and DC faults. When a problem is de-
tected, the output relay automatically disconnects
the load from both channels and illuminates the
Protect LED on the front panel. The 9441A
has electronically balanced inputs and powered
octal accessory sockets for plug-in transformers
and electronic modules.
