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.
Benchmark power density – The FP 7000 delivers a total of 7000 W (2 x 3500 W @ 2 ohms) in only 2U. Lab.gruppen sound quality – impeccable sonic performance standards with durability and greater efficiency. NomadLink® network ready – Monitoring and control of key functions accessible via the intuitive DeviceControl software. Patented Class TD amplifier topology – Road-proven output stage delivers Class B audio quality with Class D efficiency. Regulated Switch Mode Power Supply (R.SMPS) – Output power remains constant even with significant drops in the mains voltage. Efficient cooling system - Unique, lightweight Intercoller copper cooling system dissipates more heat to allow extended peak output. Adjustable parameters - Selectable Gain, scalable Voltage Peak Limiter (VPL), and bridge-mode operation allow custom configuration for any application. Comprehensive protection and warning – Excessive output current, DC, high temperature, very high frequency (VHF), short circuit, open load, mains fuse protection, and soft start. XLR input connectors. Heavy-duty binding post or Speakon output connectors
The T Series is a very flexible and cost-effective amplifier platform with loudspeaker processor. All models deliver the same high peak voltage allowing high SPL with single 8/16 ohm cabinets on all models. The high voltage is also good for sharing power between the channels for applications such as bi-amped loudspeakers or subwoofers with passive tops. The amplifiers feature input via Dante, AES3 and analog. The Dante and AES3 solutions are optimized for daisy-chained distribution of 2-channel audio for distribution to many amplifiers without the need for external switches/repeaters/ splitters. A simple Dante system has a daisy chain with the mixing console at one end, a WiFi access point at the other end and the amplifiers in-between.

COMPACT MODERN DESIGN
Compact size (2U-Rack Height) with up to 1200W per channel@2ohms
these amps save valuable rack space without compromising power output.
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.
