Power amplification at its best means absolutely linear handling of any complex audio signal.
Our BUX 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 Series Power Modules, share component topology and maintain technical coherence by increasing heat sink size according to power output.
BUX 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.

This professional stereo power amplifier, working in class-H mode, provides 2x1600W, at an efficiency of around 85%.
A massive 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.
