Controls & Functions 1.Low Level OUT RCA jacks LINE OUT LINE IN LINE OUT LINE IN R L R X3.71 L X3.60 The LINE OUT allows you to build multiple amplifier systems without having to use splitter cords to distribute the signal. Now it is simply a matter of bringing one set of RCAS into the first amplifier, then using the line out RCA jacks as the feed to the next amplifier. 2. Low Level Input RCA jacks LINE OUT LINE IN LINE OUT LINE IN R L R X3.71 X3.60 L These inputs are for signal cables from the

Controls & Functions 4.Subsonic Filter Control SUB SONIC 15Hz 40Hz Variable Subsonic Filter (15Hz - 40Hz) : The Subsonic lter will roll o all of the unwanted frequencies below 15Hz - 40Hz. This will allow the ampli er to use that wasted power on the audible bandwidth. 5. Bass Boost Control BASS BOOST 0 +18dB By using the bass boost function, bass notes at 45Hz are emphasized as much as 18dB. X3.71 X3.60 8 CONTROLS & FUNCTIONS

Controls & Functions 7. Low Level Filter Control LOW PASS 50Hz 150Hz This control is used to set the desired low pass frequency (50 ~ 150HZ). The filter acts to cut-off frequencies above the set-point. In general, the selected frequency should closely match the resonant frequency of the speaker box. 8. Phase Shift Control PHASE SHIFT 0 0 0 180 The Variable phase control allows you to adjust the relative phase relationship between your subwoofers and/or your subwoofers & other speakers

Controls & Functions 10. LED indicatior POWER PROTECTION POWER : This GREEN LED will illuminate when the amplifier is turned "ON". If it fails to illuminate, check the power connections to the Amplifier and fuses. PROTECT: The amplifier protection circuitry will disable the amplifier if input overload, short circuit or extremely high temperature conditions are detected. When the protection mode is in operation, the red LED indicator on the side panel will be illuminated, indicating the ampl

Controls & Functions 12.B-Terminal (Chassis ground) X3.60D X3.71 To avoid unwanted ignition noise caused by ground loops, it is essential that the Amplifier be grounded to a clean, bare, metal surface of the vehicles chassis. Note : GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT (1 METER). 13. Remote Power On X3.60D X3.71 To remote wire From car stereo. The amplifier is turned "ON" remotely when vehicle's stereo is turned "ON" Note : IF YOUR RADIO DOES NOT HAVE +12 VOLT OUTPUT LEAD WHEN TUR

Planning and Mounting Your System The mounting position of your Amplifier will have a great effect on its ability to dissipate the heat generated during normal operation. Under normal conditions, the heatsink will dissipate sufficient heat to avoid thermal shutdown. However please do not install the amplifier in a wooden box or similar device as this will prevent heat dissipation into the atmosphere. Temperatures in car trunks have been measured as high as (155'F) in the summer time. since

Tuning on the Amplifier The amplifier automatically turns on a few seconds after you turn your vehicle's ignition switch to ACC or ON or turn on your auto sound system, depending on how you wired the system. The POWER indicator on the top of the amplifier lights when the amplifier is on. Important : Your amplifier requires 30 amps or more of power from your vehicle's battery during operation. To protect your battery from discharging, do not operate the amp
