BUX Series ? BUX 1.4
Professional Power Amplifier

Presentation

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.

Solid DYNACORD amplifier technology at highly competitive prices. These amplifiers offer high, stable power output and a high efficiency factor on the high performance level and are therefore the ideal choice for driving a multitude of mobile and club systems. SL series power amplifiers are equipped with a comprehensive protection package and dynamic limiters. The integrated, switchable Low-Pass Notch filter (a typical DYNACORD special feature) corrects the frequency response and optimizes the transient behaviour of loudspeakers.

HIGH CURRENT TOROIDAL TRANSFORMER A high-current toroidal transformer saves rack space and minimizes hum and noise. EXCELLENT SOUND QUALITY The low T.H.D.(0.05%) and high damping factor (400 or higher) gives excellent sound quality. 2 STAGE POWER SUPPLY The high-power units (L1800 and L2400) have a 2-Stage Class-H design that maximizes their performance. EQUIPPED WITH 30Hz or 50Hz HPF All amplifiers are equipped with high-pass filters on each channel to help maintain sound quality, yet help protect the loudspeakers. EXTENSIVE PROTECTION CIRCUITS Extensive protection circuits monitor over voltage/current conditions, overheating, output shorts, and DC voltage to improve performance and reliability. CLIP-LIMITER CIRCUITS Clip-limiters on each channel are provided to help prevent distortion due to excessive signal levels. 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.
