    Blaupunkt dealer. We also recommend Blaupunkt cd or cassette units, speaker systems, and accessories to expand the listening experience which might be limited by lesser quality components.
  • Page 4 Here is where your new Blaupunkt VELOCIWTMamplifier is uniquely impressive. The Blaupunkt VELOCITYTM series of amplifiers have a very unique feature called Distortion Limiting (THD,) which tolerates high input voltage levels but prevents ugly sounding distortion products common to nearly all other amplifiers.
  • Page 5 HUSHm NOISE REDUCTION AND DOWNWARD EXPANSION GATING High quality compact discs provide very wide range volume levels with low background hiss levels. Unfortunately, the car is a very noisy electrical environment so vehicle noises (pops and alternator whine) often creep into the audio signal somewhere in the installation. Although mid and high level music tends to mask background noises, vehicle noises become quite audible, and annoying, during quiet music passages.
  • Page 6 DC voltages (O-1 5 volts) that are insensitive to noise (noise is an AC voltage). Using the optional Blaupunkt remote control (RM-1) you simply plug the remote into the amp to control the overall gain. For people wanting to interface with highly custom installations, you can use an RJ-11 telephone jack and variable resistor to achieve similar results using the circuit below, This is &...

    INSTALLATION AND SAFETY PRECAUTIONS !! WARNING !! 8 ALWAYS DISCONNECT THE (+I LEAD FROM THE BATTERY OF THE VEHICLE BEFORE DOING ANY INSTALLATION WORK! 8 DO NOT INSTALL THIS UNIT IN THE ENGINE COMPARTMENT! 8 DO NOT RUN WIRES UNDERNEATH OR OUTSIDE THE VEHICLE! !! SAFETY PRECAUTIONS !! nalyze the mounting location carefully to avoid damaging gas tanks, electrical wires, and/or draulic lines.

  • Page 8: Amplifier Controls And Operation

    AMPLIFIER CONTROLS AND OPERATION CROSSOVER FREQUENCY CONFIGURATIONS - In the full-range mode (5-50,000 Hz) the amp reproduces all frequencies heard by humans. In the (low-pass) position, only low frequency (bass) comes out of the speakers. In the (high-pass) position, only information above the crossover frequency setting is sent to the speakers.

  • Page 9: Amplifier Connections And Interface

    AMPLIFIER CONNECTIONS AND INTERFACE 1. GROUND LINE - 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. Do not run a wire up to the car battery ground for this line.

  • Page 10: Speaker Configurations

    SPEAKER CONFIGURATIONS Many audio systems can be generated from the flexible input and output configurations of this amplifier. The three most common include the following: 716 MULTI-CHANNEL SYSTEM MODE- 615 CHANNEL HIGH SUBWOOFER POWER MODE; 413 CHANNEL HIGH SYSTEM POWER MbDE. Possible in-car configurations will be covered elsewhere in this manual.
  • Page 11 One of the most difficult decisions in amplifier usage is an optimized power amplifier configuration. The Blaupunkt VEf_OC/rV”” V7000 amplifier has the versatility to offer multiple installations but the most easily understood is the SatellitelSubwoofer configuration. By breaking the audio spectrum (20 - 20,000 Hz) into two parts (e.g., above and below 100 Hz) amplifier power and associated loudspeakers...

  • Page 12: System Configurations

    SYSTEM CONFIGURATIONS H#2 OF 4 RECOMMENDATIONS) SATELLlTElSUBWOOFER USING EXTERNAL INPUTS (7 channel high-pass/low-pass) For those people wanting greater flexibility in frequency or signal level tailoring, you can insert active crossover networks between the radio and amplifier. Although the internal crossovers in the V7000 amplifier offer tremendous flexibility, the user may wish to add dedicated crossovers for tweeters, for example, that fall outside the crossover frequency limits inside the amp.
  • Page 13 SYSTEM CONFIGURATIONS (#I3 OF 4 RECOMMENDATIONS) amplifiers in channel mode) HIGH POWER “COMPETITION” CONFIGURATION (2 Although the standard configuration power of this amplifier is adequate for nearly any listener (4x4OW satellite + 2x8OW subwoofer), some people may wish for increased sound pressure levels. By installing two V7000 amplifiers in 413 channel bridge mode, a high power system can be achieved (4xlOOW satellite + 2x2OOW subwoofer + 2x2OW center channel).
  • Page 14 SYSTEM CONFIGURATIONS (#4 OF 4 RECOMMENDATIONS) “FRONT STAGE/REAR FILL” HIGH POWER CONFIGURATION (4/3 channel mode) For many listeners, they are looking for a simple “Front Sound Stage” with “Rear Sound Fill” and a dedicated subwoofer. Live music dictates that the main speakers providing a “Sound Stage” for listening be in front of you and this normally requires the most power be in front as well.
  • Page 15 FINAL INSTALLATION Proper installation of your amplifier should also address several areas; adequate mounting and ventilation, proper signal input interface, correct use of internal crossover networks, “clean” power/ground wiring, proper fusing, and power/speaker wiring. ADEQUATE MOUNTING AND VENTILATION Inevitably this amplifier will be mounted in locations with limited space. If possible, try mounting the amplifier on a vertical surface with the fins up/down for best vertical air movement.
  • Page 16 “CLEAN” POWER AND GROUND Unfortunately, the number of electronic devices in the car has grown such that care must be taken to properly install the power and ground connections of the amplifier in order to prevent overloading the charging system of the vehicle or interjecting noise. Currents are high enough that a dedicated power line should be run directly to the battery of the car, but not to the vehicle’s alternator output.
  • Page 17 POWER WIRING Most automobiles built in the last 10 years have adequate current capability for your Blaupunkt amplifier. Except for systems above 500-700 watts, the factory charging system and battery should comfortably power your audio system. Care should be taken in the choice of wire to ensure adequate current delivery to the amplifier.
  • Page 18 Check the main power connection at the battery. Check fuse in power line. If fuse is blown, replace it. If it continues to blow, see your Blaupunkt dealer. Disconnect all speakers and try to power up unit. If it now turns on, a speaker short is probable.

    ACCESSORIES / ACCESSOIRES / ACCESORIOS There are four accessories available for your Velocity amplifier which increase its flexibility and guarantees high performance for years to come. RM-1, REMOTE CONTROL: This control offers the consumer the capability of remotely controlling the gain of a subwoofer amplifier, or multiple amplifiers, from the front seat of the car.
