BUX Series ? BUX 2.8
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.

  • High-current toroidal transformers, for greater 2-ohm power and low noise
  • Independent user-defeatable clip limiters reduce distortion
  • Selectable low-frequency filters (30 Hz or 50 Hz) protect speakers and increase headroom
  • The 4000-watt RMX4050a operates on a standard 15 amp plug (120V) 
  • Both the RMX4050a and the RMX5050a feature a dual mono, high-current power supply for increased reliability and performance
  • The RMX4050a's particularly exceptional combination of cooling capacity and electrical efficiency provides robust thermal performance suitable for high continuous power in 2-ohm stereo or 4-ohm bridged applications.
  • Balanced 1/4” (6.3 mm) TRS, XLR, and barrier strip inputs
  • Touch-proof binding post and Neutrik Speakon® outputs
  • Front mounted gain controls for easy access
