AMPLIFIER FEATURE DESCRIPTIONS
STREET MACHINE AMPLIFIERS:
Each model is capable of 4 & 2-Ohms stereo per channel, or 4-Ohms mono bridged operation except the mono amps All Autotek amplifiers feature a comprehensive diagnostic system, with speaker lead short circuit, and amplifier DC
faults indicated by the red “
PROTECT” LED. which are capable of 4, 2 and 1-Ohm loads.
CAUTION: DO NOT OPERATE ANY AMPLIFIER BELOW THE INTENDED IMPEDANCE. YOU WILL CAUSE The input sensitivities for rated output powers are variable from 0.2V to 5V on the multi channel amplifiers and 0.2V to

All crossovers are fully variable in their respective ranges.
Crossover filters are 12dB/Octave.
bridged. The mono amps are capable of 4, 2 and 1-Ohm.
A POWER LED indicates the powered up and turned on condition.

-The LINE INPUT signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER setting simplifying daisy chaining of amplifiers.
-SUBSONIC: Allows you to adjust the crossover filter from 15Hz to 55Hz.
-LOWPASS: Allows yo to adjust the LOW PASS crossover filter from 40Hz to 150Hz.
LEVEL: Adjusts the input sensitivity from 0.2 volts to 6 volts.
BASSBOOST: 45Hz bass boost adjustable from 0db to 12dB.
REMOTE CONTROL: This is the input jack for the remote Level control.
LINE INPUT : The line input accepts unbalanced (RCA) inputs from 0.2V to 6V.
LINE OUTPUT : The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal.
The mono amps are capable of 4, 2 & 1-Ohm loads.
Operating the amp below 1-Ohm can cause damage to the amp not covered in the warranty.
SM3200.1 / SM4800.1 / SM6000.1 MONO BLOCK AMPLIFIERS
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.
In addition, the 4 channel models have a
Mode switch which allows you to select 2, 3 or 4 channel operation. Switch to 2 channel if you only have 1 set of RCA’s in CH 1/2 and
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
X-OVER slide switch selects the internal crossover functions:
-The input signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER setting simplifying daisy chaining of amplifiers.
-HPF: Selects the built in HIGH PASS filter, variable from 60 Hz to 1.2kHz.
-FULL: Bypasses all crossovers for full frequency range operation.
-LPF: Selects the built in LOW PASS , variable from 30 Hz to 250Hz.
LINE INPUT : The line input accepts unbalanced (RCA) inputs from 0.2V to 5V.
LINE OUTPUT : The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal.
-BASS EQ: Adjustable 45Hz bass boost from 0dB to 12dB.
Note that the LOW PASS signal is MONO.
-In the LPF position, the HIGH PASS filter acts as a subsonic filter.
-When the LPF mode is selected, a 0 to +12dB, at 45Hz, BASS -EQ is also switched in.
SM1400.4 4-CHANNEL AMPLIFIERS
The X-OVER slide switch selects the internal crossover functions:
-The input signal is routed directly to the LINE OUT RCA jacks, regardless of the X-OVER setting simplifying daisy chaining of amplifiers.
-HPF: Selects the built in HIGH PASS filter, variable from 60 Hz to 1.2kHz.
-FULL: Bypasses all crossovers for full frequency range operation.
-LPF: Selects the built in LOW PASS , variable from 30 Hz to 250Hz.
-BASS EQ: Adjustable 45Hz bass boost from 0dB to 12dB.
MODE : The mode switch allows you to choose Stereo for full range 2 channel operation or MONO for bridging operation
HIGH INPUT : If your radio/CD player does not have unbalanced (RCA) outputs, you can use the HIGH level (wire) inputs.
LINE INPUT : The line input accepts unbalanced (RCA) inputs from 0.2V to 5V.
LINE OUTPUT : The line output passes through signal from the line inputs which allows you to daisy chain multiple amplifiers from one signal.
Note that the LOW PASS signal is MONO.
-In the LPF position, the HIGH PASS filter acts as a subsonic filter.
-When the LPF mode is selected, a 0 to +12dB, at 45Hz, BASS -EQ is also switched in.
