MEAN MACHINE SERIES AMPLIFIERS Congratulations on your purchase and thank you for supporting AUTOTEK! The MM Series products have been designed to a very high level of performance, with features unavailable in similarly priced amplifiers. These amplifiers have variable crossovers built in, with added touches such as subsonic filter, bass equalization and a remote Level control module (some models) that allows subwoofer Level control from the drivers seat.
GENERAL INSTALLATION PROCEDURE System Design The success of any car stereo system relies on several factors, such as the system design, execution of the installation, and system setup. Please remember that any system is only as good as its weakest link. Please remember that higher power systems are not necessarily useful purely for high sound pressure levels, but also to establish a headroom capability, to reproduce musical peaks cleanly without distortion.
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. A POWER LED indicates the powered up and turned on condition.
MM1150.2 / MM1650.2 TWO CHANNEL AMPLIFIER APPLICATIONS FULL RANGE STEREO This is the most basic application for the 2 channel amplifiers. 1. Interconnect cable checklist: Connect the LINE INPUTS to the Radio/CD with good quality RCAcables. 2. Crossover Switch: The X-OVER switch must be in the FULL position. 3. Crossover frequency control checklist: N/Afor full range operation.
MM1150.4 / MM1550.4 / MM2050.4 FOUR-CHANNEL AMPLIFIER APPLICATIONS 4 CHANNEL FULL RANGE SYSTEM Here we show how to use the 4 channel amplifiers as straight forward discrete 4 channel full range units. The MODE switch should be in 4CH. - HI PASS: N/A - LOW PASS: N/A Interconnect cable checklist: - Connect the four inputs of the amplifier to a Radio/CD with quality RCAcables. Channels 3/4: - HI PASS: N/A - LOW PASS: N/A Minimum final loudspeaker impedances: - 2 ohm per channel.
MM1150.4 / MM1550.4 / MM2050.4 FOUR-CHANNEL AMPLIFIER APPLICATIONS Front/Rear high pass, using a 2 channel amplifier for mono sub bass The combination of a 2 and a 4 channel amplifier, utilizing their built in crossovers, makes it a snap to put together a full system with front and rear highs, with mono sub bass.
MM2050.1 / MM4050.1 MONO AMPLIFIER APPLICATION Basic application These sub bass amplifiers can be used in any of the bi-amplification systems described in this manual, replacing the 2 channel amplifiers as per the illustrations. Crossover frequency control checklist: LOW PASS: 40Hz to 150Hz SUBSONIC:15 Hz to 55 Hz BASS EQ: 0 to +12dB Interconnect cable checklist: Connect the inputs to a suitable source, e.g. a head unit with good quality RCA cables.

SETTING UP SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE 2 & 4 Channel Amplifiers General: At this point you are ready to get more specific on the settings for your amplifier. High Pass: -When in HPF operation, this setting acts as a low frequency cut off for your system reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this point. The 12 o’clock position is a great starting point.
TROUBLESHOOTING A SYSTEM The key to finding the problem in a misbehaving sound system is to isolate parts of that system in a logical fashion to track down the fault. Description of the PROTECT system built into all Autotek amplifiers The diagnostic system will shut down the amplifier, until reset by turning the head unit off, and back on. This state of affairs will be indicated by the front panel PROTECT LED lighting up under the following conditions: 1 -Asort circuit on the loudspeaker leads.
Maxxsonics Limited Warranty As the manufacturer of Maxxsonics, MB Quart, Autotek, Crunch and Hifonics car audio products, Maxxsonics USA Inc. Warrants to the original consumer purchaser the amplifier to be free from defects in material and workmanship for one (1) Year from date of purchase. All other parts and accessories of the system are warrantied to be free from defects in material and workmanship for one (1) year from date of purchase.
