BASIC Series - Intelligent Power
BASIC - that's meeting the tightest budgets and professional requirements in reliability, flexibility and sound. Alone or in combination with the other products of the Bittner portfolio. The consequent realisation of the Bittner quality standards indicates once more our understanding of the contracting business. It underlines our philosophy that cost consciousness has nothing to do with giving up standards. Compromise is a word unknown to Bittner Audio! The incorporation of detent potentiometers, clip limiter, protection circuits for any imaginable situation, as well as a first-class production process using only highest-quality components made the BASIC series the choice of most contractors.
Certainly more than basic!
High Tech SMT design Excellent sound and superior impulse response Protection Circuits: DC, LF, HF, Thermal, Short Circuit, Current Limiter, 3 ms Muting Delay XLR Inputs Speakon and Binding Posts Clip Limiter Toroidal transformers LED Indicators for SIGNAL, CLIP, PROTECT, POWER Temperature controlled, variable speed, low noise fans Detent potentiometers Stereo / Bridged / Parallel Mode Ground Lift Robust Steel Chassis 3 Year Warranty

This professional stereo power amplifier, working in class-H mode, provides 2x800W, at an efficiency of around 85%.
A passive transformer based power supply and hand selected components makes this power rating possible with exceptional audio quality and absolute reliability, even in the 2 Ohm mode. The output stage is fully protected against over-temperature, short circuit, RFI and equipped with soft start circuit and temperature-controlled fan cooling. The integral soft clip limiter protects against damage to the connected loudspeakers. The activity of a protective circuit, signal and limiter is shown for each channel by LEDʼs.
