							Thank you for purchasing this high-quality digital audio amplifier
product. This amplifier contains advanced audio amplification
technology which provides the audio quality of analog amplifiers at a
superior signal-to-noise ratio and low audio distortion while at the
same time offering extremely small size and high power efficiency.
This amplifier can be switched to drive either two speakers in stereo
configuration or a single speaker in mono configuration. In stereo
configuration, the amplifier works in half-bridge mode. In mono
configuration, the amplifier works in full bridge mode and can provide
more power to the speaker than in stereo configuration. If the output
power per speaker in stereo configuration is insufficient, it is possible
to use separate amplifiers for each speaker each of which is
configured in mono configuration.
Connect power to the amplifier BEFORE connecting the speakers to
the amplifier to avoid switch-on plop. Connect the AC adapter with the amplifier BEFORE plugging the
AC adapter into an outlet to avoid spark generation! Unpacking:Check that this package contains:
- one digital audio amplifier - Model 200
- one large AC adapter (wallwart)
