AMPLIFIER FEATURE DESCRIPTIONS
Each model is capable of 4 & 2-Ohms stereo per channel, or 4-Ohms mono bridged operation except the mono amps
which are capable of 4, 2 and 1-Ohm loads.
The input sensitivities for rated output powers are variable from 0.2V to 6V.
All crossovers are fully variable in their respective ranges.
Crossover filters are 12dB/Octave.

The 4 channel amps have the same features as the 2 channel models accept that there are 2 sets of controls. 1 set for channels 1 & 2 and 1 set for channels 3 & 4.

the unit will automatically supply signal to channels 3/4. Select 3 channel when you only have RCA's in CH 1/2 but plan to run channels 3/4 bridged. Select 4 channel if you
are providing RCA's to channels 1/2 and 3/4.

The ATA1200.1 is capable of 4 & 2-Ohm loads (not 1-Ohm). The ATA2000.1 is capable of 4, 2 & 1-Ohm loads.
Operating the amp below the capable impedance can cause damage to the amp not covered in the warranty.

Adjustable 45Hz bass boost from 0dB to 12dB.
: The mode switch allows you to choose Stereo for full range 2 channel operation or MONO for bridging operation
: If your radio/CD player does not have unbalanced (RCA) outputs, you can use the HIGH level (wire) inputs.
: The line input accepts unbalanced (RCA) inputs from 0.2V to 6V.
: The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal.

CAUTION: DO NOT OPERATE ANY AMPLIFIER BELOW THE INTENDED IMPEDANCE. YOU WILL CAUSE
DAMAGE TO THE AMPLIFIER THAT WILL NOT BE COVERED UNDER THE WARRANTY PRINTED IN THE BACK
OF THE MANUAL. 2 & 4 Channel amps are capable of 4 and 2-Ohms wired stereo and 4-Ohms wired mono
bridged. Certain mono amps are capable of 4, 2 and 1-Ohm and others are only capable of 4 & 2-Ohms.
Be sure to check the specifications matrix for specific model impedance capabilities.
