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. L.E.D FUNCTION DISPLAYS Power, Clip limiter, Signal, Protection, Mode (Parallel/Stereo/Bridged) LEDs on the front panel indicate the status of the unit in operation.

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.

InterM V-2000 Power amplifier 2Χ550W/4ohm, 2Χ300W/8ohm, 2Χ900W/2ohm bridge 1900W/4ohm

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.
