Dual-Channel Spectral Compressor Enhance your sound while you commpress. With a DL Series compressor in your studio you'll enjoy seamless compression - with no loss of sound in the high frequencies. The DL Series incorporates Drawmer's original "Auto-Compressor" circuitry, which gives you optimal results in minimal setup time, but doesn't compromise your skill with limited controls. The DL251 eliminates the "high frequency cutting" problems of full-band compressors by use of "Dynamic Spectral Enhancement" feature. It restores your high frequencies and adds additional "Spectral Energy" for that extra sonic spark. The DL241 Auto-Compressor uses many automatic functions, letting you concentrate on the overall performance and feel rather than the equipment. The result is smooth, warm and transparent audio. *2 channel, 1 rack unit Spectral Auto/Manual Compressor *Spectral enhance to restore high frequency under heavier compression. *Proprietary auto compressor with slope based attack and envelope following release *Manual attack and release control *Zero overshoot limiter (+20dB) *Dual VCA stages one for compression, one for enhance *Integrated circuit VCA for compression *Proprietary FET based discrete VCA for enhance *Proprietary log level detector (not RMS) *Side chain input *+4/-10 operation, individually selectable each channel *XLR inputs and outputs *1/4in sidechain insert jacks on each channel *Hard or Soft knee selectable *Attack and Release auto switch *Sidechain insert listen function *Bypass switch *10 segment LED metering on output lvl & gain reduction *Dynamic Spectral Enhancement feature *Peak limiter control *Stereo linkable *1 unit rack space
