APHEX SYSTEMS 661 TUBE COMPRESSOR-LIMITER

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 CIRCUITRY 
Tubessence 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?.

 Reverbs & Delays

Because it is one of the most desired effects, the FX2000 provides 12 different reverb programs, so you always have the ideal reverb for your live performance or studio needs.

Reverbs include:

    CATHEDRAL
    GOLD PLATE
    SMALL HALL
    ROOM
    STUDIO
    CONCERT
    STUDIO
    STAGE
    SPRING REVERB
    AMBIENCE
    EARLY REFLECTIONS

Specialty reverbs include:

    REVERB – reverb is synthetically turned off after a predetermined amount of time
    REVERSE REVERB – reverb envelope is reversed—it slowly gets louder

Delays include:

    STEREO DELAY – delay is processed across the entire stereo image
    TAPE ECHO – simulates classic tape echo devices, pre-dating the advent of digital delays
    PING PONG – delay signal is "bounced” from left to right at an adjustable tempo

Much More than Just Reverb and Delay

The FX2000 has some of the best-sounding reverb and delay programs, but thatʼs not all. It also provides excellent modulation effects (such as chorus, flanger and phaser), including special variations like musical pitch shifter, tremolo and even a rotary speaker simulation.

Modulation and Pitch Shifter FX:

    STEREO FLANGER (originally generated by playing back two synchronized "reel to reel” tape recorders with a finger rubbing on the flange of one of the take-up reels)
    VINTAGE FLANGER simulates a guitar fl anger stomp box
    JET STREAM FLANGER sounds like a classic analog flanger
    STEREO CHORUS (combines a slightly detuned signal with the original)
    ANALOG CHORUS simulates a guitar chorus stomp box
    VINTAGE CHORUS imitates a classic analog studio chorus
    ULTRA CHORUS creates the sound of an eight person chorus
    STEREO PHASER (combines a second, phaseshifted signal to the original)
    VINTAGE PHASER represents a guitar phaser stomp box
    DUAL PHASER processes the left and right channels separately
    ROTARY (simulation of the rotating speakers typically used on an organ) – Slow or Fast
    PITCH SHIFTER (changes the pitch of the original signal) – can be used to create harmonies with the original signal or replace it entirely with the altered pitch. Choices include stereo, two and three vocal pitch shifter
    VIBRATO – the peak frequency of the tone is periodically and uniformly changed (quickly or slowly)
    TREMOLO (common vintage guitar amplifier effect) – a fast or slow periodic variation in volume
    AUTO PANNING – signal is automatically sent from one side of the stereo image to the other, either once or multiple times

Dynamic FX:

    COMPRESSOR – reduces the dynamic range of the signal, maintains consistent signal level and thus avoids distortion associated with excessive input levels
    EXPANDER – effectively broadens the dynamic range of source signals while reducing background noise
    GATED REVERB – helps reduce background clutter by turning reverb off below a predetermined threshold level. Particularly effective on drum mics and vocals
    ANA. KOMPR/LIM. — similar to COMPRESSOR but with Limiting functionality
    ULTRAMIZER – analyses incoming signal and automatically applies compression across two independent frequency bands
    DENOISER – eliminates or reduces noise and other interference
    DE-ESSER – reduces or removes sibilance (Ssss sound) from signal
    WAVE DESIGNER – allows you to influence the envelope by adjusting Attack and Release of the signal

Psychoacoustic FX:

    EXCITER – adds artificially generated overtones to the original signal, increasing presence and perceived loudness without significant increase in signal level
    ENHANCER – functions much like a dynamic pitch equalizer
    ULTRA BASS – sub-harmonic processor combined with bass exciter and limiter
    STEREO IMAGER – divides the signal into middle and side signals, allowing individual signals to be amplif ed when desired and placed on the stereo image
    ULTRA WIDE – creates a broader stereo image
    BINAURALIZER – also creates a broader stereo image and compensates for crosstalk between both speakers

Filter/EQ FX:

    AUTO FILTER – influences the frequency response of a signal. Two filters are included: low pass allows low frequencies to pass and suppresses high frequency content; high pass does the exact opposite
    LFO FILTER - Controls the rate of oscillation effects
    PARAMETRIC EQ – allows you to control the bandwidth, frequency and amplitude of a signal
    GRAPHIC EQ – the sound spectrum is divided into eight (8) adjacent frequency bands, which can be cut or boosted, bandwidth is predetermined

Distortion FX and Amp Simulations

The FX2000 is also equipped with distortion, amplifier and speaker simulation including VOCAL DISTORTION, TUBE DISTORTION, GUITAR AMP, TRI FUZZ, SPEAKER SIMULATION, RING MODULATOR and LO-FI.

Special FX:

    VINYLIZER – adds clicks and/or noise to the signal, reminiscent of old vinyl records and tape machines
    SAMPLER – allows you to record and playback up to five (5) seconds of program material
    VOCODER – allows the input signal to modulate another signal (usually a synthesizer sound), creating the familiar "talking synthesizer” effect
    VOICE CANCELER – removes mono vocal parts from stereo recordings for "instant Karaoke”
    RESONATOR – simulates and oscillating system that amplifies a specific frequency

Our FX Combinations Go to 11

Sometimes you want to add a little (or a lot) of color to your reverb and delay patches. The FX2000 allows you to layer modulation effects like chorus, flanger, pitch or tremolo with your reverb or delay selections.

FX Combinations include:

    Chorus & Reverb
    Flanger & Reverb
    Leslie & Reverb
    Pitch & Reverb
    Delay & Reverb
    Tremolo & Reverb
    Phaser & Reverb
    Chorus & Delay
    Flanger & Delay
    Pitch & Delay
    Tremolo & Delay

Enhanced User Editability
Logical grouping of parameters, along with the combination of encoders, buttons, LEDs and an easily readable LED display, make operating the FX2000 a breeze. You are free to edit up to seven parameters per preset, and then save them for future use in the 100 provided memory locations.
Value
With its extremely powerful processing capability and versatile array of features, the FX2000 will become the busiest tool in your audio arsenal. Stop by your BEHRINGER dealer today and find out why more professional sound engineers are turning to the FX2000 as their primary FX processor— both in the studio and on the road.
