manual abstract
Normal source units can only keep a constant 12 volts to 2 or possibly 3 amps. This wire should also be run on the away from RCA cables. • CAP+: This 8 gauge terminal is internally wired in parallel with the +12V on the StreetWires Power connector. It is the ideal connection point for the positive side of a capacitor to increase the amplifier’s performance. • CAP-: This 8 gauge terminal is internally wired in parallel with the GND on the StreetWires Power connector. It is the ideal connection point for the negative side of the capacitor to increase the amplifier’s performance. Double check all the previous connection installation steps, in particular, the speaker and power wiring. Securely mount the amplifier. If everything is in order, reconnect the vehicle’s negative battery connection and begin following the feature setup and adjustment steps. Feature Setup and Adjustments 1. Selecting the Input Sensitivity Range – Before you turn on your system, you must select the proper input sensitivity range on your amp using the button labeled INPUT SENS located in the GAIN CONTROL section of the control panel. • Setting for Aftermarket Source Units: Refer to your aftermarket owner’s manual for line level output specification. If the specification is not available, please follow the instructions listed below. X1 POSITION: 100mV–1V (Typically for RCA Input) • Setting for Factory (OEM) Source Units: To check the amount of voltage that is present from the source unit, take a multi meter, or a volt/ohm meter, on the AC setting, (range from 100mV up to 10 volts) attach the positive and negative leads directly to any exposed speaker. It will not matter if the polarity is correct, it will read the same amount of voltage. X10 POSITION: 1V–10V (Typically for Speaker Level Input) Note: It is important not to have the amp set up to receive a low voltage signal and give it a high voltage signal. Doing this can cause damage to the amp. 2. Adjusting The Gain Control(s) – Before you start setting your amp gains, be sure to defeat all EQs (“off” position). You want to set the gain levels properly BEFORE applying any equalization. Start with the source unit’s volume around . of the way up, and the gain on the amp all the way down (counter-clockwise). Slowly increase the gain clockwise until the speaker starts to distort. Immediately decrease gain until the distortion goes away. This will be a good reference point on the volume control to where the signal starts to distort. Remember every CD will be different; use common sense and constantly listen for obvious distortion and adjust volume accordingly. The gain on the amp has nothing to do with how much power the amp can produce, just how fast the amp puts out max power. Just like in an automobile, full throttle is very rarely needed. 3. Adjusting the Hi, 12dB / Low, 24dB Mono @ 85Hz Switchable X-over Frequency Controls– • Setting for Subwoofers: First enable the electronic crossover by selecting the “ON” position of the X- OVER switch, and then select the “L-PASS” (Low pass) position on the L-PASS/H-Pass switch. By selecting this setting, the amp crosses the signal over at 85Hz with a 24dB/Oct roll off. Meaning the signal tapers off fairly quickly at frequencies over 85Hz. • Setting for Components and Separates: First enable the electronic crossover by selecting the “ON” position of the X-OVER switch, and then select the “H-PASS” (High pass) position on the L-PASS/H-Pass switch. By selecting this you are giving the speakers the frequencies from 85Hz to 20kHz. The 12dB/oct roll off means that the frequencies under (lower than) the set 85Hz, will taper off at moderate slope. • Setting for Full Range (No Crossover): To disable the electronic crossover, select the “OFF” position of the X-OVER switch. This setting will allow the amplifier to play all frequencies. 4. Adjusting The Variable ThunderEQ – Adjust the dial clockwise to add the desired amount of bass boost. Keep in mind that there is a lot of boost available, 18dB of 40Hz, so begin with a low boost setting (around 3dB) and try to stay below 6dB whenever possible. Remember that for every 3dB of additional boost you dial in, you are asking the amplifier to double its power output for this boost region. 5. Remote Subwoofer Level Control (Remote Gain) – Let’s say the amplifier’s gain is set at halfway, when the remote subwoofer level control is plugged in, you now have external control of the gain from zero to halfway. The installation of this level control is NOT necessary to get full power from the amplifier. 6. Prizm EFX – Now that you have completed adjusting all your amplifier settings, you can set the lighting effects to your personal taste. • Selecting Colors: You can change the backlit colors simply by turning the dial labeled PRIZM COLOR, located in the MTX PRIZM EFX section of the control panel, left or right. Starting at the left most position, the colors range from RED to GREEN, BLUE, and then RED again. You can choose a...
