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!

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.
