CB Series ? CB 1402
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.
