  • Page 3 INTRODUCTION Congratulations on your purchase of the world’s finest brand of car audio amplifiers. We have invested tremendous effort in the design process of the new VELOC/TT”series amplifiers in order to achieve superior musical performance. Leading edge technologies such as Distortion Limiting and HUSHTM noise reduction and gating, previously found only in the professional audio sound reproduction and enhancement market, have been implemented into your amplifier...
  • Page 4 UNDERSTANDING YOUR AMPLIFIER’S FEATURES WHAT IS AN AMPLIFIER?... An amplifier, by definition, is a device that receives a small audio signal on its input and reproduces it with larger voltages (or current) on its output. Ideally there should be no internal modifications of the signal other than voltage or current level.
  • Page 5 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 ELECTRICAL PIN-OUTS Controlled Amplifiers) & Used in Professional Audio for some years, but totally new to the car audio world, is a remote control gain devices called a “VCA”. This is a small integrated circuit that can control the feed- through gain of a circuit from a remote location.

    INSTALLATION AND SAFETY PRECAUTIONS !! WARNING !! VEHICLE BEFORE DOING ANY INSTALLATION WORK! !! SAFETY PRECAUTIONS !! draulic lines. Every effort should be made to provide adequate ventilation, protection from engine heat, direct sunlight, rain, and dirt. This unit is designed for use only with 12 volt DC negative ground vehiclt systems. This unit is NOT designed for use with common ground speakers.
  • Page 8: Amplifier Controls And Operation

    AMPLIFIER CONTROLS AND OPERATION 1. TONE CONTROLS - The tonal quality of the signal passed through the amplifier can be modified in the bass and treble regions using the internal tone controls. Although somewhat redunda to those on the radio, these controls help correct for small equalization problems in the car without changing the controls on the radio.
  • Page 9: Amplifier Connections And Interface

    AMPLIFIER CONNECTIONS AND INTERFACE 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. It should remain less than 3 feet in length (1 meter).
  • Page 10: Speaker Configurations

    SPEAKER CONFIGURATIONS Many audio systems can be generated from the three basic speaker output configurations of this amplifier. They are: 2 channel stereo; 1 channel mono; and 3 channel mixed stereo/mono. Possible in-car configurations will be covered elsewhere in this manual. 2 CHANNEL-STEREO MODE 1 CHANNEL-MONO/BRIDGE MODE SUBWWFER...
  • Page 11 SYSTEM CONFIGURATIONS OF 4 RECOMMENDATIONS) STEP-UP POWER CONFIGURATION One of the most difficult decisions in amplifier usage is an optimized power amplifier configuration. The Blaupunkt series of amplifiers has the versatility to offer multiple installations but the most easily understood is the “step-up power” configuration. You simply run RCA cables from the radio back to the amp, wire up a good set of coaxial 6x9”...
  • Page 12 SYSTEM CONFIGURATIONS SATELLITE/SUBWOOFER CONFIGURATION Another common configuration is that of a “satellite/subwoofer” speaker system. By breaking the audio spectrum (20 - 20,000 Hz) into two parts (e.g., above and below 100 Hz) amplifier power and associated loudspeakers can be better proportioned to the needs of most music. Bass information usually requires a lot more power than mid and high frequencies for proper reproduction.
  • Page 13 SYSTEM CONFIGURATIONS MULTI-MODE CONFIGURATION Somewhat new to the car audio world is the “multi-mode” configuration which permits three speakers to operate from a 2 channel amplifier. The benefit is a “quasi-satellite/subwoofer” system that can be constructed using passive components (i.e., capacitors and inductors) but we highly recommend the optional “Blaupunkt Bass Bridge”...
  • Page 14 SYSTEM CONFIGURATIONS MULTIPLE AMPLIFIER CONFIGURATION For the audiophile, there is the possibility to install three stereo (2 channel) amplifiers and achieve unparalleled sound quality. Using the optional remote control, you can also run the gains of all three amps up and down together from one remote. Performance is tremendous since you are dedicating individual amplifiers to parts of the music spectrum thus gains and tone controls can be adjusted independently to achieve a truly balanced sounding system.
  • 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. Wire diameter size (gauge) is an important factor for high power audio systems.
  • Page 18 TROUBLE-SHOOTING GUIDE PROBABLE CAUSE & SOLUTIONS No power (blue remote turn-on Check connections to the amplifier’s + 12 volt, Ground, and remote lines light is off) Verify the appropriate voltages are at their terminals (1 l-1 5 VDC). Check the main power connection at the battery. Check fuse in power line.
