The Aphex Model 661 is a totally new type of compressor incorporating vacuum tube technology with the latest innovations in audio compression. This single-channel compressor/limiter is loaded with features, consolidating for the first time in one rack space, three patented Aphex circuits: Tubessence�, Easyrider�, and High Frequency Expander�.The UNIQUE 661 CIRCUITRYTubessence is a true tube circuitwhich provides that vintage tube sound without high the heat, bulk, short life, fragility, and sonic variability found in traditional tube designs.Easyrider is an Automatic mode that actually works, consisting of the Wave dependent Compressor� (WDC) circuit which takes the guesswork out of compressing individual instruments and vocals especially in live mixes. WDC automatically adjusts attack and release times according to the complexity of the program material. Its No-Knee� compression curve makes the transition into compression virtually invisible.In the Manual mode, the Model 661 provides the full complement of compressor adjustments such as Ratio, Attack, and Release, for maximum flexibility. Express yourself and get those punch, slap, fat, pump, and squeeze sounds fast and clean.The 661 includes the patented High Frequency Expander� (HFX) which decompresses high frequencies, with user-adjustable ratio and corner frequency. Add life and air to your compressed signals without fear of background noise pumping.The Spectral Phase Refractor� restores clarity and punch to your tracks. Bass frequencies are more defined with more apparent power. Higher frequencies also seem to gain more detail and presence.Use the Model 661 to control dynamics for mixdowns, protect your sound system's loudspeakers from transients and distortion or shape the sound of individual instruments and vocals. Compress dynamic levels without fear of reducing frequency response. Whatever type of dynamics control you're looking for, it can be done with the Model 661 Tube Compressor / Limiter Expressor�.
