AMPLIFIER FEATURE DESCRIPTIONS

MEAN MACHINE AMPLIFIERS:
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.
Tri-Mode operation with any stereo pair of amplifier channels is possible, as with all
bridgeable amplifiers.
The input sensitivities for rated output powers are variable from 0.2 volts to 6 volts.
All crossovers are fully variable in their respective ranges.
Crossover filters are 12dB/Octave.
A POWER LED indicates the powered up and turned on condition.
The X-OVER slide switch selects the internal crossover functions:
X-OVER Channels 1&2:
-DUPE 3&4: Will bypass the crossover settings for CH1&2 and duplicate CH3&4 settings.
-HP: Selects the built in HIGH PASS filter, variable from 10 Hz to 1.2kHz.
-FULL: Bypasses all crossovers for full frequency range operation.
X-OVER Channels 3&4:
-LP: Selects the built in LOW PASS , variable from 30 Hz to 150Hz
-HP: Selects the built in HIGH PASS filter, variable from 10 Hz to 1.2kHz.
-FULL: Bypasses all crossovers for full frequency range operation.
BASS EQ: 45Hz bass boost variable from 0-9dB. (When CH1&2 X-OVER is in the DUPE
position, the BASS EQ function becomes available for CH1&2 as well.
INPUT MODE: The input mode switch allows you to choose 4CH for full range 4 channel
operation or 2CH for bridging operation.
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. This signal is FULL RANGE
regardless of the X-OVER settings.
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 LINE INPUT signal is routed directly to the LINE OUT RCA jacks, regardless of the X-
OVER setting simplifying daisy chaining of amplifiers.
BALANCED INPUT: Accepts balanced line inputs from 0.2 volts to 18 volts.
LEVEL: Adjusts the input sensitivity from 0.2 volts to 6 volts.
PHASE: Fully variable time alignment from 0 to 180 degrees.
BASS EQ: Fully variable 45Hz bass boost from 0db to 9dB.
SUBSONIC: Allows you to adjust the crossover filter from 15Hz to 35Hz.
LOW PASS: Allows yo to adjust the LOW PASS crossover filter from 35Hz to 250Hz.
Each model is capable of 1ohm minimum.
Both models have MASTER / SLAVE capabilities for linking 2 models together.
BRIDGED PROTECT: When 2 amplifiers are used in the "Master / Slave" configuration,
you should use a standard RCA cable. With the RCA cable installed, if one amplifier goes
into the Protect Mode, it will automatically shut down the second amp to reduce the risk of
damage to the second amplifier.

All Autotek amplifiers feature a comprehensive diagnostic system, with speaker lead
short circuit, and amplifier DC faults indicated by the red "PROTECT" LED.
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. 4
Channel amps are capable of 4 and 2-Ohms wired stereo and 4-Ohms wired mono
bridged. The mono amps are capable of 4, 2 and 1-Ohm.
MM404 4-CHANNEL AMPLIFIER
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.
MM1000.1D / MM1500.1D 1-CHANNEL MONO AMPLIFIERS
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.
