STREET MACHINE AMPLIFIERS Autotek is proud to introduce the finest high end car audio products available and would like to thank you for your continued support. The Street Machine Series has been designed to a very high level of performance, with features unavailable in any other products.
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 STREET 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 volt to 5 volt. ! All crossovers are fully variable in their respective ranges.
SM2-400 / SM2-1000 / SM2-1200 / 2 CHANNEL AMPLIFIER APPLICATIONS FULL RANGE STEREO This is the most basic application for the Street Machine Series 2 channel amplifiers. 1. Interconnect cable checklist: Connect the LINE INPUTS to the Radio/CD with good quality RCA cables. 2. Crossover Switch: The X-OVER switch must be in the FULL position. 3. Crossover frequency control checklist: N/A for full range operation. 4. Line Level: Refer to the section “Setting up systems after installation for best performance”.
SM2-400 / SM2-1000 / SM2-1200 / 2-CHANNEL AMPLIFIER APPLICATIONS Stereo high pass with mono low-pass in a 2 way active, or bi-amplified system In this application we will use a 2 channel amplifier for the high frequencies, and a second one for the low frequencies, or mono sub bass. Please consult the speaker specifications to determine maximum amplifier power requirements. Interconnect cable checklist: Connect the inputs of the HIGHS amplifier to a Radio/CD with good quality RCA cables.
SM2-3500 / 2 CHANNEL AMPLIFIER APPLICATIONS FULL RANGE STEREO This is the most basic application for the Street Machine Series 2 channel amplifiers. 1. Interconnect cable checklist: Connect the LINE INPUTS to the Radio/CD with good quality RCA cables. 2. Crossover Switch: The X-OVER switch must be in the FULL position. 3. Crossover frequency control checklist: N/A for full range operation.
SM2-3500 / 2-CHANNEL AMPLIFIER APPLICATIONS Stereo high pass with mono low-pass in a 2 way active, or bi-amplified system In this application we will use a 2 channel amplifier for the high frequencies, and a second one for the low frequencies, or mono sub bass. Please consult the speaker specifications to determine maximum amplifier power requirements. Interconnect cable checklist: Connect the inputs of the HIGHS amplifier to a Radio/CD with good quality RCA cables.
SM4-800 / SM4-1000 / 4 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. Channels 3/4: - HI PASS: N/A - LOW PASS: N/A Interconnect cable checklist: - Connect the four inputs of the amplifier to a Radio/CD with quality RCA cables.
SM4-800 / SM4-1000 / 4 CHANNEL AMPLIFIER APPLICATIONS 2 way active, or bi-amplified system with mono bass This application shows how easily a 2 way active system can be implemented using a 4 channel amplifier. Channels 1 and 2 will be used for highs, and channels 3 and 4 for mono bass.
SM1-1000 / SM1-1500 / A/B MONO AMPLIFIER APPLICATIONS Basic application These sub bass amplifiers can be used 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 PHASE: 0 to 180 degrees 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 SM2-400 / SM2-1000 / SM2-1200 / SM2-3500 / SM4-800 / SM4-1000 General: At this point you are ready to get more specific on the settings for your amplifier. High Pass: -When in Hi Pass 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 Crunch 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 - A sort circuit on the loudspeaker leads.
