PROFESSIONALPOWER AMPLIFIERS ADVANTAGE SERIES
1. INTRODUCTION
Congratulations on your purchase of the ALTAIR power amplifier ADVANTAGE series. Our
dilated experience in the design and manufacture of audio power amplifiers has led us to carry out a
series of general purpose bipolar power amplifiers of great performances.
There is a lot the characteristics that make of the ALTAIR power amplifiers ADVANTAGES series,
one of the most highlighted of the audio professional market, here enumerated some:
Multiple protection
Has improved the circuits of DC output protection by relay. Guiding directly the power
transistors output to the loudspeakers binding post has improved several qualities of the signal
quality, the damping factor and the global reliability.
Equally, the conventional thermal switches (based on contacts) has been substituted of the
power modules by solid state sensors whose information completes the double condition of speed
fan control and discharge the thermal protection.
All the protection situations are displayed in the power amplifier front panel.
Clipping circuit limiter
Since most of the damage caused to loudspeakers, and even to the power amplifiers, is
normally the result of the permanence of the power unit during long periods of time in clipping,
it is necessary to have limiter mechanisms that assure their reliable operation.
For this purpose, all the ADVANTAGE series power amplifiers has a "soft-clipping" circuit that
acts on the output power by comparing the input and output signals. Once it detects a distortion or
other noticeable cut, it stabilises the integrity of the output signal thereby avoiding overloading and
saturation levels that might damage the system. This limiter effect is switchable on or off internally.
Under control
The conception of the new loudspeakers, especially the uses for low frequencies is based on
that the amplifiers that govern them behave as ideal voltage amplifiers, is say with zero output
impedance. The ADVANTAGE series approaches to this value nearly zero presenting a damping
factor better than 300 what redounds in a perfect control of the loudspeaker voice coil position along
their excursion.
Naturally, you want to use your power amplifier just now, but before beginning is important
that you read this manual. This manual will help you to install and use your new power amplifier. It is
very important that you read it carefully, mainly the paragraphs marked as NOTE, PRECAUTION and
DANGER, for your security.
Save the original packing, you can re-use it to transport the power amplifier. NEVER SHIP THE
POWER AMPLIFIER WITHOUT THE ORIGINAL PACKING.
