CB Series ? CB 1902
Rugged Power Amplifier

Presentation

The CB Series is a medium cost ensemble of amplifiers covering the most used power specifications. The four offered models share the well proven RAM Audio topology for ease of servicing.

The latest breakthrough in component assembly and manufacturing processes are present in this new Series.

All the models are equipped with high efficiency toroidal transformers and long life capacitors in a common, sturdy two U steel chassis.

The sum of these specs put them on the front row of cost/effectiveness for all fixed and mobile uses.

Features
* 2U heavy duty steel chassis
* Modular construction for easy servicing
* Symmetrical layout for even weight distribution
* High efficiency toroidal main transformer
* Oversized, high energy, linear power supply
* Dual, parallel or bridged operation
* Twin balanced inputs (Neutrik XLR connectors)
* Three dedicated Speakon outputs
* High quality components used throughout
* Efficient back to front cooling
* Dual, continuously variable speed axial fans
* Fault, signal, and clip indicators
* Functional integrated front panel design
* Heavy duty alloy carrying handles
Protections

*

Calibrated mains fuse
* Independent channel supply fuses
* Input signal muting at turn on
* Continuous short-circuit protection (CSP)
* Thermal overload protection
* Intelligent clip-limiter (ICL)
* Progressive Ramp input signal
* Currentless relay operation (CRO)

This professional stereo power amplifier, working in class-H mode, provides 2x800W, at an efficiency of around 85%.

A passive transformer based power supply and hand selected components makes this power rating possible with exceptional audio quality and absolute reliability, even in the 2 Ohm mode. The output stage is fully protected against over-temperature, short circuit, RFI and equipped with soft start circuit and temperature-controlled fan cooling.  The integral soft clip limiter protects against damage to the connected loudspeakers.  The activity of a protective circuit, signal and limiter is shown for each channel by LEDʼs.
