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.

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.

| Solid DYNACORD amplifier technology at highly competitive prices.
These amplifiers offer high, stable power output and a high efficiency factor on the high performance level and are therefore the ideal choice for driving a multitude of mobile and club systems. SL series power amplifiers are equipped with a comprehensive protection package and dynamic limiters.
The integrated, switchable Low-Pass Notch filter (a typical DYNACORD special feature) corrects the frequency response and optimizes the transient behaviour of loudspeakers.
