User manual BOSS RIPPER RIP695

[. . . ] The 4 Channel (RlP796/896) amplifiers feature a pair of individually adjustable low pass crossovers and high pass crossovers, as well as +18dB variable Bass Boost. All RIPPER amplifiers have been designed with 100% MOSFET power supplies, ensuring extremely quick switching response for cleaner power. - Protection Circuitry 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 LED indicator will be illuminated, indicating the amplifier has gone into a self-preservation mode. If you observe that the Protection LED is illuminated, please check the system carefully to determine what has caused the protection circuit t o engage. [. . . ] If the amplifier has shut down due to a thermal overload condition, please allow it to cool down before restarting. If the amplifier shut down because of an input overload or short circuit, be sure to correct these conditions before attem~tina Your RIPPER amplifier was designed t o operate efficiently into 2 Ohm loads in the stereo mode. This means r8 per'channd when using parallel wiring. Increasing the number that you can install four s e at low frequencies (up to 100 Hz) produces an acoustic coupling effect. This of woofer & c c e e s your power output by 3 dB per speaker. r When operating at 2 ohms, the amplifiers will increase their output power by approximately 50%. The current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2 ohm load. If you lack adequate current, your music-repduction will be distorted. / P l e ~ ~ o t The gain control of any car audio amplifier should not be mistaken for volume control. It is e: a sophisticated device, designed to match the output level of your audio source unit to the input level of the amplifier. Do not adjust this input level to maximum unless your input level requires it. Ignoring these instructions will result in a n input overload to the amplifier, and excessive audio distortion. Do not operate the amplifier when it is unmounted. Attach all audio system components securely within the automobile to prevent damage. Do not mount this amplifier so that the wire connections are unprotected or in a pinched condition, or likely to be damaged by nearby objects. Before making or breaking power connections in your system, disconnect the negative terminal of the vehicle battery. Confirm that your head unit and any other equipment is turned off while connecting the input jacks and speaker terminals. If you need to repla e-it-with a fuse identical to that supplied a fuse of a different type or ratiirg may result in damage to your with the s f l s i n g systA i c h i s not covered by the manufacturer's warranty. Troubleshooting Before removing your amplifier, refer to the list below and follow the suggested procedures. Always test the speakers and their wires first. No Output Confirm that all terminal strip connections are secure and tight. Both the "+I 2v" and the "~EM0TE"terminalsmust have +12v referenced to chassis ground. Confirm that the audio signal source (car radio, equalizer, etc. ) is connected and is supplying output signal. To check if the amplifier is supplying signal, unplug the RCA cables from the signal source (but leave them plugged into the amp). [. . . ] To check if the amplifier is supplying signal, unplug the RCA cables from the signal source (but leave them plugged into the amp). Briefly tap the center pin of each of the disconnected RCA plugs with your finger. This should produce a noise (feedback)in your speakers. Only one channel works Confirm that all speaker strip connections are secure and tight. Check the "BALANC~control on the head unit (or other source) to verify that it is set to its midpoint. [. . . ]
