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.

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.

Crownʼs new CTs series of power amplifiers are remarkable for their loud, punchy sound; sustained, tight bass; and superior protection against overheating and overload. This paper explains the design features behind those advantages. After reading this information, youʼll know why Crown CTs amps sound better than the competition. CTs amplifiers can provide large amounts of power into various loads, such as 2, 4, 8 ohms and 70V. With most power amps, the maximum output power tends to drop as the load impedance increases. But with the CTs series, the power stays the same at almost any impedance. 2-ohm Dual (per Ch.) 250W 4-ohm Dual (per Ch.) 600W 8-ohm Dual (per Ch.) 600W 16-ohm Dual (per Ch.) 300W 70V Dual (per Ch.) 600W 4-ohm Bridge 500W 8-ohm Bridge 1200W 16-ohm Bridge 1200W 140V Bridge 1200W Crown switching power supply for less weight Sustained Power on long-duration signals due to regulated, "stiff” power supplies with incredible energy storage (huge filter capacitors). Extra Hidden Power during high-level transients and during incomplete use of all the channels. Overheating and overload protection thanks to the sophisticated TLC circuitry which compresses the signal only when needed. Compression is controlled not by temperature, but by signal voltage. This keeps the loudness up during compression more than with competitive amps. |
