Vanco A220SUBAMP. Subwoofer Amplifier, 220watts total

The A220 features a stereo/mono line level audio input that can receive full band audio from
any audio amplifier, receiver or preamp or an LFE input from an appropriately featured device.
The A220 also features a stereo speaker level input. Amplified stereo audio will pass through
the A220 full-band and unprocessed to a pair of connected stereo speakers. The speaker level
input will also be processed by the A220 crossover, phase and volume controls to enhance
and optimize low frequency content. This feature is an easy way to add amplified in-wall or
in-ceiling subwoofers to multi-room audio amplifiers that do not have zone-specific line level
outputs.

The adjustable crossover allows fine-tuning the A220 Sub OUT setting to properly
complement any full-range speakers or room conditions.

In addition the A220 features a phase adjustment that provides sub performance
optimization given the sub’s placement relative to the main speakers.

The A220 is audio-sensing so anytime an audio signal hits the A220 line or speaker level
inputs, the amp will instantly turn ON. The amp will also turn itself OFF after 15 minutes if
no audio signal has been detected. There is also a 12VDC Trigger that will turn the A220 ON
when 12-24VDC is applied and turn the amp OFF when the voltage is removed.

The A220 is the perfect match for many applications but makes a particularly great running
mate with the Vanco Beale Street Audio D2.1 Stereo amp with subwoofer out, (see the
system illustrations in the Connections section).
