Aphex is constantly As a result of these modification made from time products without Specifications from those This product by U.S. patents 5450034, Tube Compressor/Limiter Expressor® /Easyrider® withTubessence ® Model 661 The 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 Aphex patented circuits; Tubessence ® , Easyrider ® and High Frequency Expander ® . Tubessence is a true tube circuit which provides that “vintage” tube sound without, high heat, bulk, short life, fragility and sonic variability found in traditional tube designs. Easyrider is an Auto mode that actually works, consisting of the Wave Dependent Compressor™ (WDC) circuit which takes the guess work 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. It’s No-Knee™ compression curve makes the transition into compression virtually invisible. In the Manual mode, the Model 661 provides the full compliment 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™ (SPR) 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. What ever type of dynamics control you’re looking for, it can be done with the Model 661 Tube Compressor/Limiter Expressor ® . FEATURES • Auto or full Manual operation. In Auto mode, compression parameters constantly change for • A true tube circuit (Tubessence) in the output stage for a “warm”, “live” and • HFX allows the use of high compression ratios without • SPR increases apparent bass energy level, • Use Sidechain Access jacks for creative processing (de-• Stereo, dual mono or master/slave APPLICATIONS Music Production - Improve Sound Reinforcement A roadable tube compressor/Broadcast & Post Production A great vocal processor Project Studios - Musicians - The ultimate compressor bass, keyboard Tube Compressor/Limiter Expressor® /Easyrider® withTubessence ® Model 661 BACK PANEL RETURN SEND OUTPUT INPUT MODEL 661 EXPRESSOR MADE IN USA APHEX SYSTEMS LTD.
