BUX Series ? BUX 3.4
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.

Crown CDi Series amplifiers are professional tools designed and built for installed sound applications. The series includes four models which are identical except for output power: CDi 1000, CDi 2000, CDi 4000, and CDi 6000. All are rugged and lightweight, and offer unmatched value in their class.

  • Extremely versatile; rated for 2-, 4-, 8-ohm loads and 70V and 140V outputs.
  • Switch-mode universal power supply.
  • Intuitive front-panel LCD screen for quick, easy configuration.
  • Onboard digital signal processing includes crossovers, EQ filters, delay, and output limiting.
  • Up to 20 user defined DSP presets are available.
