INTRODUCTION
Congratulations on your recent purchase of the Russound
DPA-4.8 8-channel amplifier. The DPA-4.8 high-current, high-
quality amplifier is the heart of the home theater or multi-
zone system. The DPA-4.8 8-channel amplifier is capable of
amplifying four stereo line level sources (CD players, tape
decks, preamplifiers, tuners, etc.) simultaneously in multi-zone,
multi-source installations. The eight amplifiers are arranged in
pairs to provide four stereo amplifiers. With separate gain
controls for each channel, sound levels can be preset to
accommodate most rooms. The Main Bus Input allows for two
or more stereo amplifiers to share the same audio source.
With the stereo/mono selector in the mono position, two
amplifiers can serve as mono outputs. In the mono position
the four stereo pairs can be bridged to two stereo pairs for
higher output power. The DPA-4.8 power output is 50 watts
per channel into 8 ohms, and 75 watts into 4-ohms. Bridged
adjacent outputs provide 100 watts of power into 8-ohms
and 150 watts of power into 4-ohms. All this power is backed
by two high output toroidal transformers. Each amplifier out-
put channel incorporates thermal, short circuit protection and
Russound’s unique Dynamic Clipping Sensor that allows for
better headroom and volume without clipping or distortion
that is normally heard in most amplifiers.
The Russound DPA-4.8 amplifier is built with pride. Fidelity,
reliability and quality are the primary objective. Russound
products are guaranteed to provide years of enjoyment.
