II. Introduction
The PSB CustomSound series CWA-1 subwoofer amplifier is a complete solution
for powering and equalizing any in-wall or in-cabinet passive subwoofer. It is an
ideal companion for the PSB CWS8 in-wall subwoofer and any other custom
installed sub. When paired with the CWS8 the CWA-1 will deliver solid dynamic
bass for music and movie sound tracks.
The amplifier has a built-in variable crossover that makes it easy to achieve a
seamless blend with the main speakers, while 24dB/octave lowpass filters
prevent the subwoofer from being easily localized by the ear, increasing
placement flexibility. A crossover bypass position is provided for use with home
theater electronics that perform their own bass management functions.
Equalization is provided with two extension frequencies to suit large and small
subwoofers. A special feature is a parametric equalizer to help eradicate any of
the typical room related problems.
The CWA-1 is attractively housed in a standard 17 inch wide chassis that can be
adapted to a compact 2 space x 19-inch rack enclosure. Auto on/off and 12 volt
amplifier switching and easily accessible controls make the CWA-1 subwoofer
amplifier as convenient to use as it is exciting to listen to. It also utilizes a high
power discrete class AB output stage. The high current design allows continuous
operation into 2 ohm loads.

with glass cleaner to remove heavy soil.
