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 PA series amplifiers in order to introduce great
sound to the consumer at an affordable price. 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.
Audio amplifiers take power from the car battery and convert it to audio power. Although much of
the energy output is sound, a considerable amount of power is lost as heat. Such heat loss must
typically be dissipated via large heat sinks, thus creating heavy metal amps with a large footprint.
In the audio world, Class ‘D’ amps have recently
helped reduce this wasted heat, allowing them to use
a smaller enclosure, but their poor fidelity limits them
to bass reproduction only. In contrast, conventional
Class ‘AB’ amps march on with their high fidelity, but
poor efficiencies. Therefore, the need still exists for
an amp with high fidelity, but with low heat and a
small chassis.
Class ‘T’, invented and patented by Tripath
®
Technologies, provides the best of both worlds with
high quality sound, yet low heat dissipation. Due to
the remarkably low heat generated we can design
very small, hide-away boxes but also creatively shape
the external housings from plastics or other materials.
With heat losses of only 1⁄3 to 1⁄4 of an ‘AB’ design,
Tripath opens up a whole new application world for
compact, small design, attractive amps. Looks cool,
runs cool!
Your new Blaupunkt Amplifier offers some important features:
■
“Break-away” design allowing the internal amplifier to be
removed from the housing and mounted in a “hide-away”
location
■
REM1, Remote gain control (operates in bass mode only)
■
HLA1, High Level Adapter allowing for speaker level voltage to
drive the amplifier
■
Plugs that allow for wiring the vehicle first then connect the amp
■
Continuously variable high-pass and low-pass crossover filters
■
Bass boost control (fixed gain)
■
Interchangeable colored plastic control lenses (optional)
■
2 ohm (non-bridged) capability
■
0.3-6.0Vrms input capability allowing for wide range drive voltage
capability from a receiver or other media device
