Did You Buy the Right U.S.Amp? There is a U.S.Amp for every purpose! From raw power to exquisite sound quality and everything in between, U.S.Amps offers state-of-the-art technology to meet your every need. INSTALLATION Amplifier Mounting: sure your choice is free from excess heat, moisture, and vibration. Under the vehicle seat or in the trunk are common mounting locations.
CARE AND FEEDING OF YOUR BATTERIES As mentioned before, most batteries are built for the relatively light chore of starting the engine. Unless you have the room and ambition to install an upgraded high-powered alternator, your system current requirements may exceed the charging capability of your car’s electrical system.
For the internal amplifier, adjustable from 50 Hz to 500 Hz @ 12dB. WARNING: All U.S.Amps require a grounded input connection. DO NOT use ground-loop isolation devices or high/low conversion devices on the input of your U.S.Amp! AX-TU600C 2-Channel Amplifiers Controls and Features Full Subsonic...
(Shown here is AX-1000, but the diagram is also applicable to AX-2000.) Amplifier Input The amplifier MUST receive input on BOTH RCA jacks for proper operation. Amplifier Output The low level output can be connected to other amplifiers. Input Gain is variable from 1 to 9 volts for full output.
The AX-4360C features a selectable two-way electronic crossover with independent front and rear mid-high frequency adjustment and 2 ohm per channel stability. Power is provided by four 75 watt channels that can be bridged as front and rear pairs into a 4 ohm load for a total of 180 watts per bridged pair.

INPUT Gain AX-600DE INPUT One Ohm Stable Design (Shown here is AX-600DE, but the diagram is also applicable to AX-3200DE.) Amplifier Input The amplifier MUST receive input on BOTH RCA jacks for proper operation. Input Gain is variable from 150 mV to 3 volts for full output. Best results are achieved by adjusting the control to the lowest setting in relation to the output of the source unit.

Why Tubes? You may know that a transistor is a modern, efficient, less expensive version of a vacuum tube, which is the device that made sound recording and reproduction possible in the first place. Now, the electronics industry has been trying for many years to equal the sound quality available from tubes.
VTCSD (continued) VTCSD “follows” the high voltage tube signal STRAIGHT INTO THE SPEAKERS, adding only current in a form of “amplifier power steering” — free from voltage gain or negative amplifier feedback! Vaccum tubes are renowned for their high dynamic range and smooth emphasis of even-order harmonics.
NEVER, NEVER, NEVER! NEVER USE A U.S.AMP WITH A GROUND LOOP ISOLATOR ON THE RCA’S OR AN ISOLATED INPUT SIGNAL. U.S.Amps are input-isolated at the factory and require an input ground for proper operation. NEVER INSTALL OR MOUNT YOUR AMPLIFIER DIRECTLY TO A SPEAKER ENCLOSURE OR ANYWHERE ELSE WHERE SEVERE VIBRATION IS PRESENT.
