THANK YOU FOR CHOOSING BLAUPUNKT! Congratulations! You are the now the owner of an exceptional car audio amplifier from the audio enthusiasts at Blaupunkt. Our engineering staff has spent considerable time refining our MPA series amplifiers in order to introduce great sound to the consumer at an affordable price. With these products we focus on sonic performance but balanced with rugged design and flexible installation. Not only do we offer you a great product but also a supportive owners manual.
SAFETY CONCERNS We always recommend you have your Blaupunkt amplifiers professionally installed but the installation process is often so easy that the average consumer can achieve success with little trouble. Regardless of the person installing, you should be sure to review the following points before proceeding with the installation: ■ READ THE MANUAL! Understanding the product and installation limitations before ■ WEAR SAFETY GLASSES AT ALL TIMES - Flying debris are always dangerous.
SYSTEM PLANNING Before wiring up an audio system that may not achieve the sound quality you want, be sure to choose a system concept that fits your listening requirements. Basic systems, a receiver with internal 4x20 watts and 4 coax speakers, are adequate for many listeners. But, when you want to really “feel” the music, you will need some kind of subwoofer amplifier/speaker combination.
VEHICLE WIRING VEHICLE FUSING For safety purposes, a high current fuse (or circuit breaker) MUST be installed in line with the amplifiers(s) immediately at the battery to prevent vehicle damage should the battery line in advertently shorted to the vehicle chassis. The chart at the right shows the recommended master fuse sizes for an average audio system with noted “rms” output power levels. POWER WIRING Most vehicles built since 1990 have adequate current capability for your amplifier.
INPUTS & CONTROLS 1 2 3 4 5 6 7 8 9 10 The inputs and controls for this amplifier are explained in the summaries below and reference the numbered call-outs above. 1.) LOW-PASS CROSSOVER CONTROL (ch 1 & 2) - Once the “crossover frequency setting” is set to “LOW-PASS”, this control adjusts the frequency for which all signals BELOW this setting are passed on to the speakers. 2.
POWER CONNECTIONS & SPEAKER OUTPUTS 1 2 3 1.) POWER CONNECTIONS GROUND - This is the high current ground connection to the chassis of the car. It should be fastened to a clean ground connection in the car, capable of handling high current loads and within 3 feet (absolutely no longer than 3 feet). TRIGGER - This allows the amp to be remotely switched on from the radio and normally uses a dedicated “trigger” line output. If one is not available, simply use the power antenna line.
SYSTEM CONFIGURATION #1 Full-Range High-Pass Subwoofer Full-Range High-Pass 3 Channel Multi-Mode (Active) + CH1 – Speakers + CH2 – + CH3 – CROSSOVER LOW FLAT HI + Bridged – SUBWOOFER OFF ON This amplifier offers a very unique installation advantage by including 3 independent amplifier channels with 2 active crossover sections. The inputs require only 2 signal leads (left and right) and derive the bass signal from these two.
SYSTEM CONFIGURATION #2 Full-Range Full-Range Full-Range Full-Range Subwoofer 2 Channel Dual Subwoofer Mode + CH1 – Speakers + CH2 – + CH3 – CROSSOVER + Bridged – LOW FLAT HI SUBWOOFER OFF ON The largest improvement in sound quality always comes when adding some kind of subwoofer via a dedicated subwoofer amplifier and electronics crossover.
