Power amplification at its best means absolutely linear handling of any complex audio signal.
Our BUX II Series are unique, powerful amplifiers built to meet the highest professional requirements, thanks to new circuit philosophy that guarantees outstanding performance with field proven reliability.
With these qualities, RAM Audio units outperform most modern amplifiers in terms of technical specs and pure sonic performance.
To achieve industrial economy and efficiency, the BUX II Series Power Modules, share component topology and maintain technical coherence by increasing heat sink size according to power output.
BUX II Series have been designed giving extreme attention to all production steps from the engineering stand point. All boards are naturally double sided plate-through fibre glass. Most advanced SMT circuits are used for overall reliability, ease of assembly and full field servicing.

L.E.D FUNCTION DISPLAYS
Power, Clip limiter, Signal, Protection, Mode (Parallel/Stereo/Bridged)
LEDs on the front panel indicate the status of the unit in operation.
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.

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

A full model revision takes Yamaha's high-end PC-N power amplifiers to the next level - the PC-1N
Series. The new PC-1N Series amplifiers feature an extraordinarily solid low end, rich midrange,
and superbly defined highs. They also deliver fast response and exceptional stability even in the face
of serious power supply limitations. Refinements throughout this expanded five-model lineup make
these amplifiers the new benchmarks for quality, reliability, and versatility in professional applications.
Frequency Response: 10 Hz – 40 KHz. Output Power: 2 x 400 Watt / 8Ω RMS, 2 x 700 Watt / 4Ω RMS,
1400 Watt / 8Ω bridge RMS. Weight: 13 Kg.
