User manual MB QUART RLP254 INSTALLATION

[. . . ] This feature will then send signal to the amplifier in line automatically turning the unit on as well. Audio Signal Sense has a 60 second window from the time that signal ceases to when the MX Controller and amplifier power down. This feature is included so that your controller and amplifier do not power down in between tracks or while changing discs etc. (Both MX-1 & MX-2 feature Audio Signal Sense as well as standard Remote wire capabilities. ) MX-1 Premium High-to-Low Level Converter: Easily add an aftermarket amplifier to any OEM radio system with this deluxe line-level controller that converts factory high-level speaker wires into unbalanced low-level (RCA) outputs. [. . . ] These indicators give the user a chance to identify incorrect settings or high distortion before it is damaging to the equipment allowing them to correct the volume or settings. - GREEN: Indicates a Pre-Clip condition, which is safe and normal operation. - YELLOW: Indicates a Soft-Clip condition, which is safe and normal operation, but you are close to a hard clip. - RED: Indicates a Hard-Clip condition which is potentially damaging to the MX-1, amplifiers, speakers and subwoofers in the system. Evaluate and adjust crossovers and Levels so that this condition is not present. 4 MX-1 Main Diagram Low Level RCA Outputs + _ Right / Left SUB + _ Right / Left REAR + Right / Left FRONT Optional remote input + 12 volts Remote output REMOTE INPUT 40V 30Hz 100Hz 35Hz 250Hz 15Hz 35Hz 4V 0dB +10 dB 1V 9V BOOST BANDWIDTH FREQUENCY MX-1 CLIPPING CONTROL GREEN: PRE-CLIP YELLOW: SOFT CLIP RED: HARD CLIP LINE LEVEL CONVERTER Subwoofer 40V 4V 4 CH MONO / HIGH LEVEL 15Hz 15Hz 200Hz 4V 9V 200Hz HIGH LEVEL F & R INPUT CONTROL FRONT HIGH PASS FILTER 12 dB/OCT REAR HIGH PASS FILTER 12 dB/OCT FRONT & REAR STEREO OUTPUT LEVEL SUBWOOFER INPUT MODE SELECTOR BASS REMOTE REM BAT REM BAT OUT + IN - PRE-AMP OUTPUT BALANCED LINE OUTPUT MXR-1 MIN MAX VOLUME GREEN: PRE-CLIP YELLOW: SOFT CLIP RED: HARD CLIP POWER R FRONT L R REAR L R SUBWOOFER L R/F L/F + + + R/R MXR-1 REMOTE CONTROL R/F L/F R/R L/R SUB RADIO + - + - + - + - + - Factory Radio High Level Speaker Wire Outpus L/R + SPEAKER WIRE INPUT Ground High Level Speaker Wires + _ SUBWOOFER INPUT LEVEL PARAMETRIC BASS EQ LOW PASS FILTER 24 dB/OCT SUBSONIC FILTER 24 dB/OCT SUBWOOFER OUTPUT LEVEL Speakers _ + _ Aftermarket Amplifier 5 + _ Speakers + _ + _ + _ + _ 6 PRE-AMP OUTPUT BALANCED LINE OUTPUT REAR SUBWOOFER MX-1 Connecting Low Level RCA Cables To Amplifier REM BAT REM BAT OUT + IN - POWER FRONT Ground Optional input Low Level RCA Outputs + 12 volts W/5 amp fuse Right / Left Right / Left Right / Left Remote Input REAR SUBWOOFER FRONT Low Level RCA Connections 1. Use high quality RCA cables to connect the MX-1 to the aftermarket amplifier per the diagram on this page. Observe the Left (white) and Right (red) polarity as well as Front and Rear on both MX-1 and the aftermarket amplifier. Aftermarket Amplifier Power Connections 1. Connect the remote (REM OUT) output of the MX-1 to the remote input on the aftermarket amplifier. Connect the battery (BAT+) terminal to a constant +12 volt source with a 5 amp in-line fuse (not supplied). Note: Do not install the fuse until the entire installation is complete and you are ready to test. Connect the remote (REM IN) terminal to the radio output wire that provides a +12 volt output when the radio is on and 0 volts when the radio is off. If the radio does not have a +12 volt output, do not use this terminal. The LOW PASS FILTER allows frequencies below your selected setting to pass thru while cutting out frequencies above your selected setting. This means that the SUBSONIC FILTER has a steep cut-off and allows for very precise tuning. The SUBSONIC FILTER allows frequencies above your setting to pass thru while cutting out damaging and unwanted frequencies below your selected setting. This control is used to match the output signal level from your headunit. This control is used to adjust signal output voltage to your amplifier. Use caution when adjusting the signal output to be provided to your amplifier as you can damage your amplifier if you provide more signal than your amplifier is rated to handle. CLIPPING CONTROL: While adjusting the headunit, RLP254, or amplifiers, the CLIPPING CONTROL LED may illuminate in one of the following colors to alert you of an existing condition. These indicators give the user a chance to identify incorrect settings or high distortion before it is damaging to the equipment allowing them to correct the volume or settings. - GREEN: Indicates a Pre-Clip condition, which is a safe and normal operation. - YELLOW: Indicates a Soft-Clip condition, which is a safe and normal operation, but you are close to a hard clip. - RED: Indicates a Hard-Clip condition which is potentially damaging to the RLP254, amplifiers, speakers and subwoofers in the system. [. . . ] Low output power 1 - Check that level controls have been set up properly. 2 - Make sure that the battery voltage, as measured at the amplifier's and MX accessories +12 volt and ground terminals, is 11 volts or more. Fuses blowing 1 - Insure that the voltage to the unit does not exceed 15 volts. 2 - A short on the main +12 volt cable from the battery to the vehicle chassis will cause the main fuse to blow.
