Blaupunkt VA4100 manual Thank YOU for Choosing Blaupunkt, Amplifier Benefits & Features

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 Velocity series amplifiers in order to introduce great sound to the consumer. 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. This manual can be used as a teaching guide due to its brief, but informative, explanations of amplifier and system design. We are also very concerned about the end consumer using proper installation techniques for the highest performance possible from their new audio products. MOST important to us are the concerns with safety and the installation process. Since our Blaupunkt retail dealers have the tools and experience for an optimized and safe installation, we always recommend they do the final vehicle integration. But, should you choose to install these products yourself, please take the time to read this manual completely and abide by all precautions.

AMPLIFIER BENEFITS & FEATURES

“THERMAL-THROTTLE” TEMPERATURE PROTECTION

Unlike “dragster” style amplifiers that put out lots of power for a few minutes, our Velocity series amps are engineered for full throttle, everyday driving. With our incredible Blaupunkt “Thermal Throttle”, our amps keep on playing without overheating, the common shut-down mode for most amplifiers.

All amplifiers heat up some over time. Using our moving voltage rail design, once warm, the rails pull back to prevent long term overheating thus preventing full shut off or even possible damage, as most other amps do. Once initiated this temporary system gain pullback lets you know you are really pushing the system hard but it’s not letting you down going into full shut down.

UNIQUE INSTALLATION FLEXIBILITY

Included in your amplifier kit is the very cool looking side rails and end caps. The side rail system allows you to butt amps side-by-side building a multi-channel monster of a system but with everything trimming out beautifully. An added benefit of the side rails and caps is the dressing down and hiding of all cables preventing any kind of snagged wires.

REMOTE GAIN CONTROL

You will find a very nice remote gain control for the amplifier. This gain control works only in the subwoofer mode (low-pass) providing about 20dB of gain range to dial in accurate bass levels or to simply pound out the tunes if desired.

NOISE ISOLATION MODE CONTROL

Inside the amplifier are isolation circuits to help prevent the intrusion of noise into the audio path. These circuits are turned on or off via the small switches visible through the bottom plate. Noise currents may enter the system via signal cables should there be small ground voltage differences. These are sometimes heard as a varying pitch with engine speed (alternator whine). The vehicle may also have a poor antenna ground, or overly sensitive AM radio tuner front end, which can result in low level back ground tones (birdies) in some parts of the AM radio band (550kHz-1710kHz).

Should either of these conditions occur, use a small screwdriver to slide the switch to the “ON” position and they should be eliminated. If no problems are detected, leave in the “OFF” position for maximum audio system performance.
