FEATURES
The PA2X amplifier series from PulseAudio are an ideal solution for residential
and commercial audio installations that require a simple setup and great
sound output. With a small footprint, but high output, these Class D amplifiers
can sit on a desktop, or can easily be mounted on a wall or within a rack using
the included mounting brackets. The amps can be used in a stereo system,
but can also be switched for use in bridged or mono applications. The inputs
consist of two stereo audio inputs, two RCA inputs, and a single 3.5mm input
for versatility. Also includes an auto-ON feature so the units do not need to
