BUX Series ? BUX 1.0
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.

BASIC Series - Intelligent Power

BASIC - that's meeting the tightest budgets and professional requirements
in reliability, flexibility and sound. Alone or in combination with the other
products of the Bittner portfolio.
The consequent realisation of the Bittner quality standards indicates once
more our understanding of the contracting business. It underlines our philosophy
that cost consciousness has nothing to do with giving up standards. Compromise
is a word unknown to Bittner Audio!
The incorporation of detent potentiometers, clip limiter, protection circuits for
any imaginable situation, as well as a first-class production process using only
highest-quality components made the BASIC series the choice of most contractors.

Certainly more than basic!

High Tech SMT design
Excellent sound and superior impulse response
Protection Circuits: DC, LF, HF, Thermal, Short Circuit, Current Limiter, 3 ms Muting Delay
XLR Inputs
Speakon and Binding Posts
Clip Limiter
Toroidal transformers
LED Indicators for SIGNAL, CLIP, PROTECT, POWER
Temperature controlled, variable speed, low noise fans
Detent potentiometers

The LD Systems DP600 Power Amplifier offers an amplifiying level of 2 x 300 W  2 Ohm

The new DEEP2 amp series features four class-H power amplifiers with toroidal core offering amplifying levels from 2 x 400 W till 2 x 810 W at 4 Ohm. During the development of this series we attached a great importance to the reliability and the durability of the amps in continuous operation, this is why we used exclusively high end and selected components for the construction of these products. The DEEP2 series features a Clip Limiter as well as every common protection circuits. These amps are 2 Ohm and 4 Ohm (bridge) stable in continuous operation. On the rear panel you will find all the common In- and Outputs. The DEEP2 series will convince every user thanks to a dynamic and very clear sound which is perfectly adapted for Subbass applications as well as for multifunctional speakers. All models are lightweight and feature a robust steel plate housing and a very user friendly and compact design. The DEEP2 series will prove to be a profitable and reliable choice for bands, renting companies and professional users thanks to its excellent price/performance ratio.
