A Input Mode The MODE switch will sum or combine the right and left channel signals in the 2CH position to improve bass performance when bridging the amplifier to mono. Use the 4CH mode when driving four full range speakers. Mono Mode Stereo Mode 4 B Xover Mode The XOVER Mode switch sets the type of crossover that will be active. 4 channel models will have two switches, one for each set of channels. XOVER FULL LPF HPF C Full Range Adjustment This setting is for large speakers (6x9 ) or speakers when a subwoofer is not included in the system. The amplifier audio signal is not filtered so the full range audio signal is sent to the speakers. XOVER FULL LPF HPF D Low pass Adjustment Set the crossover switch to LP, ensure the crossover frequency is set at 100Hz or below. This feature must be used with a subwoofer to filter out all mid to high frequencies that only full range speakers should produce. Low pass Filter 30Hz 250Hz E High pass Adjustment Set the crossover switch to HP and turn this control to 65Hz or above when using speaker s smaller than 6 x 9. When a subwoofer is used in the system, this feature is designed to filter out all low bass frequencies that only subwoofers should produce. High pass Filter 60Hz 1.2KHz F Bass Boost This control adjusts the bass boost at 45Hz, from 0 to +12dB. Start from 0 and slowly increase to the desired level. Use this control with extreme care as failure to do so may result in damage to the subwoofers. BASS Boost 7
G Level Setting This is a critical step to insure your amplifier is properly adjusted to match the signal output level of your source unit. THIS IS NOT A VOLUME CONTROL Gain This control is used to match the input level of the amplifier to the output level of your head unit. We recommend the method below, as failure to follow these steps may damage the audio system. 1. Turn the amplifier Gain to zero 2. Turn the volume of the head unit to ¾ and the bass and treble to zero 3. Adjust the amplifier Gain/Level control until the desired maximum volume is achieved without distortion. 4. Make fine adjustments to tune your install. 4ch - Systems 2Sch - 8

PROBLEM POSSIBLE REASON SOLUTION Amplifier not switching on. LED = OFF (not Red or Green ) Amplifier not working, status LED = Red No sound LED = Green No +12V to power wire No power to remote wire Fuse broken No Ground connection Amplifier too hot Speaker wires shorted RCA Signal Gain control not set up Head Unit Amplifier Speakers Check fuses and connections to battery Check Remote Turn ON connection(s) to head unit Replace fuse with correct type and amperage Check ground cable is correctly connected to the amplifier and vehicle / body chassis Move amplifier to vented area Turn head unit down Check that there are no speaker wires shorted to another wire or to the vehicle chassis Check RCA connection to head unit Ensure you have set up the amplifier gain level control Check head unit volume level Check all power, remote on and ground connections Check speakers are correctly connected. Check speakers for wire shorts 11
