R EVOLUTION OF POWER STREET MACHINE AMPLIFIERS SM1600.2 / SM1400.4 SM3200.1 / SM4800.1 / SM6000.
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. The input sensitivities for rated output powers are variable from 0.2V to 5V on the multi channel amplifiers and 0.2V to 6V on the mono models. All crossovers are fully variable in their respective ranges. Crossover filters are 12dB/Octave.
SM1600.2 2 CHANNEL AMPLIFIER APPLICATIONS FULL RANGE STEREO This is the most basic application for the SM Series 2 channel amplifiers. 4. MODE: Should be in the STEREO position. 5. Line Level: Refer to the section “Setting up systems after installation for best performance” 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.
SM1400.4 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. 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 RCA cables. Channels 3/4: - HI PASS: N/A - LOW PASS: N/A Minimum final loudspeaker impedances: - 2 ohm per channel.
SM1400.4 4-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. Channels 1/2: - HI PASS: 100 Hz LOW PASS: N/A Interconnect cable checklist: - Using good quality RCA cables, feed the front and rear outputs of a head unit to the inputs of the 4 channel amplifier as shown.
SM3200.1 / SM4800.1 / SM6000.1 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 SM1600.2 / SM1400.4 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 - A sort circuit on the loudspeaker leads.
OEM Integration Accessories MX-1 Premium High To Low Level Converter * Converts High Level OEM speaker wires to Ultra Clean RCA Low Level Outputs * High Level Inputs: Accepts all types of High level Inputs including floating ground and high voltages up to 30 volts. * Audio Signal Sense / Hardwire Turn-On: Audio sense detects music signals from the OEM wires and activates the MX-1. As an option, the module also offers a remote turn-on wire.
