L-1400/1800/2400

Professional Power Amplifier

The new L-Series Power Amplifiers deliver high-efficiency and powerful sonic performance for audio professionals

    Features
  • COMPACT MODERN DESIGN
  • - Compact size (2U-Rack Height) with up to 2400W 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.
  • 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.

SKU: IS-333.

Product Description

The new L-Series Power Amplifiers deliver high-efficiency and powerful sonic performance for audio professionals. Our engineers used Class-H technology to create amplifiers with high efficiency and improved reliability. Extensive protection circuitry guards against over-voltage and excessive current, temperature-related problems, shorted outputs, and DC voltages. Additionally, clip-limiting circuitry, variable-speed cooling fans, and a damping factor greater than 400, combine together to make im
