INTRODUCTIONINTRODUCTION
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 VELOCITYTM series amplifiers in order to achieve
superior musical performance. Leading edge technologies such as Distortion Limiting and high Signal-
to-Noise Voltage Controlled Amplifier input stages, previously found only in the professional audio sound
reproduction and enhancement market, have been implemented into your VELOCITYTM amplifier.
For maximum performance and reliability we highly recommend that your new VELOCITYTM series
amplifier be installed by an authorized 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.
Finally, we remind you to practice safe listening habits using common sense. Continuous exposure to
listening levels over 100 decibels may cause permanent hearing loss. Many high power, multi-speaker
systems today are capable of Sound Pressure Levels exceeding 130 dB.

KEY FEATURES
#Distortion Limiting (THDL) is entirely new to the car audio aftermarket and is used to reduce the
annoying acoustical pops and cracks present during high signal levels. It is acoustically transparent
until high signal levels drive the amplifier into distortion.
#2 ohm stability allows for paralleling of multiple speakers for increased power output and/or
additional speakers for additional sound pressure levels due to increased cone area.
#Switchable 100 Hz high-pass filters limit the lower bass signals from entering small 3.5 or 4 inch
speakers thus better distributing the low frequency power to additional power amps for dedicated low
frequency speakers.
#Wide range input gain controls (0.3 - 6.0 V rms) allow for a variety of radio interface voltages, even
directly from the high level outputs of many factory radios.
#Independent front/rear gain controls allow for separate loudness level settings of the front and rear
speakers in the vehicle without adjusting the fader control in the radio.
#High impedance differential inputs sense noise riding on the RCA input cable center conductor and
shields and effectively subtracts the noise out of the input stage.
