Smart Amp Technology:
Both models incorporate a SAT
(U.S. Amps’ exclusive Smart Amp
Technology) that precisely monitors
and tracks vital amplifier information,
including the type and frequency of
fault conditions , battery voltage,
and amplifier temperature. A
built-in computer stores data that
can be read by the Dealer with a
U.S. Amps data port interface to
aid in system problem-solving.
In addition, SAT keeps permanent
record of the amplifiers’ serial
number and time of operation.
Smart Amp Technology:
Amplifier Input:
The USA-300 and 300x 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. Sensitivity150mv - 3 Volts.
Amplifier Input:
Active 24db Low Pass Crossover:
The low-pass crossover can be infinitely
adjusted to “roll off” at 24db per octave at
frequencies between 50Hz and 500Hz. The
crossover can be defeated for full-range
operation.

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.

WARNING:
U.S. Amps require a grounded
input connection. DO NOT use
ground-loop isolation devices
on the input of your U.S. Amp!
WARNING:
Subsonic Filter:
To optimize amplifier power in the
audible frequencies, a defeatable
36 Hz subsonic filter provides a 12db
per octave roll-off.

Gain Control:
The gain control is water and dust
proof for long life and high fidelity.
The input sensitivity can be infinitely
adjusted from 150mv to 3Volts.

Remote
Bass Gain:
The amplifier
volume can
be adjusted
remotely from the passenger compartment,
independent of the system volume. The RBG
works within the input volume range set by the
GAIN control, and is about 75% effective. The
RGB comes with a knob and 15’ of cable.
