input the stereo high pass signal at 18db and output the summed-
mono low pass signal at 24db to another amplifier, or vice-versa. The
crossover can be defeated for full-range preamp output.

Controls and Features
Amplifier Input:
The USA-200 and 400 feature
input isolation and a built-in
voltage divider that will accept
input signals from nearly any
source.
It is necessary to
provide input to both channels
when operating the amplifier.
Input Sensitivity is variable from
250mv to 10 Volts.

Gain Control:
The gain control is water and dust proof for long life and
high fidelity. The input sensitivity can be infinitely adjusted
from 250mv to 10 Volts.
Smart Amp Technology:
Both models incorporate a non-computerized version of SAT (U.S. Amps’ exclusive Smart Amp
Technology) that precisely monitors each amplifier channel, the battery voltage, and amplifier temperature.
In the event of a fault condition, SAT will activate to protect the amplifier from damage.
Connections:
All power and speaker connections are via a heavy duty barrier
terminal with gold plated hardware. Use at least 10 gauge wire
for all power and ground connections.
Clear Plexiglas Bottom:
U.S. Amps are hand-crafted to a high standard of quality in our Gainesville, Florida factory, and are
thoroughly inspected for both cosmetic and operational perfection. A clear bottom panel displays the
attention to detail found in every U.S. Amp.
