INTRODUCTION Thank you for purchasing a DD Audio amplifier. DD Audio amplifiers are painstakingly designed to provide years of high-performance listening pleasure. To achieve optimum performance we suggest you have your amplifier installed by an Authorized DD Audio Dealer. it is also highly recommended that you read this Owner's Manual to familiarize yourself with the many features of your amplifier.
WARNING BD Audio amps are built to push speakers fo extremely high volumes beyond what your ears can safely handle for extended periods of time. Prolonged exposure io excessively high volume can cause permanent damage to your hearing. In addition, operation of a motor vehicle while listening to audio equipment at high volume levels may impair your ability to hear external sounds such as: ohms, waning signals, or emergency vehicles; thus, constituting a potential traffic hazard.
CONTROL AND CONNECTION FOR M SERIES AMPLIFIERS Lie O37 CGO AL DID MBa INPUT: the masker cupfuls. Sad for connecting RCA preamble REMOTE: signal cables from the sources unit the amplifier. PWR LED: Indicates the amplifier ie grounded, and receiving +12V and REM power. PRO LED: indicates a general malfunction dus to speaker short, thermal limits, power amp overload, out of operating voltage range, or DC offset. BANI: Matches the output voltage of the sources signal fo the amplifier's input section SUBSONIC.
CONTROL AND CONNECTION FOR M SERIES AMPLIFIERS [STEER [7 +H2V: BND: Connect to a fused cable from the Connect fo a ground wire going positive terminal of your battery. directly to the chassis of your Minimum power cable size is 0 gauge. vehicle. Minimum cable size is 0 gauge. REM: Connect to a switched +12V cable.
REMOTE CONTROL VOLTAGE BUGLE Connect the remote control to the REMOTE port on the amplifier with the supplied tads cabs. VOLTAGE: Displays the charging system voltage at the amp. The voltage display will ends fo be calibrated after installation. 1. Test the resting voltage at the amplifier's power terminals with a multi meter 2.
MOUNTING YOUR AMPLIFIER = Mount your amplifier in a dry, well-ventilated environment. = Before mounting the amplifier be sure the mounting location and screw placement will not present a hazard to any cables, wiring, fuel lines, fuel tanks, hydraulic lines or other vehicle systems or components. + Securely mount the amplifier using appropriate hardware so that it does not come [loose in the event of a collision or 3 sudden jolt to the vehicle.
INSTALLATION 1. Disconnect the negative cable from the car battery. 2. Due to the power requirements of the Amplifier, the +12V connection should be made directly to the positive terminal of the battery. For safety measures, install an in-line fuse holder {nol included) as close to the battery's positive terminal as possible. The fuss ampere rating should net excess the total value of the amplifier's rated maximum cement draw.
INSTALLATION (continued) 8. Tum the amp off and connect the speaker wire fo the amp. Pay intentional to the polarity {+ and-). If hooked up incorrectly it can cause poor sound dus to phasing issues. 10. Connect the RCA cables or high-level shames to the amp 11. Douala check the amplifier controls to verify they are sat comely for your system. 12. Now you can tun on the system and begin the fine tuning process. Tum the amp gain all the way down. Tum the head unit volume to somewhere around 75%. 13.
TROUBLESHOOTING: MO POWER + Check GND connection. = Check voltage at the amplifiers +12V and REM terminals. = Hack fuses. NO SOUND {NO OUTPUT + Check all cable routing for shorts or faulty connections. « Check speakers to verify they are in props repeating condition. PROTECTION (Mos! Common Causes) = SPEAKER SHORT: A connected speaker has a shorted or damaged speaker lead or voice coil. * THERMAL: The amplifier overheated.
TROUBLESHOOTING (continued): POOR BASS RESPONSE » Check speaker cables for revers polarity of one channel. BUZZING SOUND » Check the amplifier and source unit ground connections. = Check RCA cable connections and possibly replace RCA cables with a better shielded cable or reroute RCA cables away from power cables. WHINING NOISE « Engine noise can be caused by poor grounding of amplifiers, source units, signal processors, batteries or alternators.
