[USED] BECOS FX CompIQ TWAIN Dual Band/Stacked Compressor for Guitar and Bass

CompIQ TWAIN is a precision tool for dynamic audio processing of bass and guitar signals, which gives tremendous control over compression parameters and then some. It features adaptive auto attack & release timing presets and independent compression controls for knee, threshold, ratio, and make-up gain – on each band. It can work as a dual-band compressor/limiter with variable crossover point, or as a stacked compressor with separate controls for each analog engine – at the flick of a switch. In either mode, harmonic saturation can be injected on each of the dry line band’s, and then be mixed to taste with the wet compressed line for perfect tonal balance. Separate gain reduction displays make the compression effect visible, so you can always know how hard or soft the lows and highs are processed.

Designed around the highest performance Analog Engines® from THAT Corp., the CompIQ TWAIN provides compression controls only found in studio gear. Beside dual-band processing, the two independent analog engines can be fully stacked (in series), achieving the compression warmth particular to slower optical compressors – a feature rarely seen in a pedal, and never before available with this level of tweaking.

The CompIQ TWAIN goes beyond just compression and steps into EQ/Preamp territory by enhancing the instrument’s tone without the need for a dedicated EQ. Slightly unbalancing the level of processing on each frequency band means you can either enhance or tame Lows or Highs. And because you can do this on the Dry-line as well – by using the Cut filters or Boost levels of the Saturation section -, you can separately blend Lows and/or Highs over the compressed Wet-line. The result of this processing adds a dynamic coloring to the tone, but careful balancing can also preserve the original voicing of the instrument. This feature is especially useful in Stacked processing mode, where you may trade some frequencies for the elastic compression feel. These can be easily restored by only mixing back what is missing.

A preamp section allows the trimming of the input signal’s level. This can be used to control how hard the compressors are pushed up front. Strong signals can sometime activate compression too early, so down to -9dB of padding is available. Weaker instrument signals can be doubled in amplitude with up to +6dB of gain. The preamp affects both the Wet and Dry line, and here the saturation engines are also responding to trimming. Sometimes, the trimmer can be used as a one-knob balancer when switching from one instrument to another.

A Side-Chain Filter with three presets is available for Lows processing only. This helps to recover punchy transients that are lost during higher compression, but it can also be used as a stand-alone blooming audio effect. By slightly delaying compression on the low-frequency spectrum – which is still being touched by the make-up gain -, the audio becomes fuller-sounding and more percussive. In Low (L) mode, the side chain’s first-order filter introduces a progressive attenuation into the control signal with the lowest point of -12dB@90Hz. This is more than enough to free up the momentary strokes on a bass instrument, or for percussive playing in general. If even more of attenuation is needed in the side-chain, the Deep (D) filter dives to -12dB@200Hz, making this setting more usable for guitar or for bright basses.

Independent band-controls for Hard/Soft Knee selection, 50dB of Threshold range to accommodate not only instruments but also line-level sources, up-to-limiting continuous Ratio selection, and +20dB of Make-up Gain make the CompIQ TWAIN incredibly powerful and versatile. The Dynamic Auto Timing (Fast / Slower presets) also available for both bands reduces the setup complexity and provides a musical response, suitable for virtually any musical application.

The CompIQ series of compressors is not gonna alter the magic voice of your instrument. They preserve the original guitar or bass tone while providing unobstructed, pristine audio compression. The high dynamic range of these compressors allows for natural-sounding clean tones and low noise, artifact-free audio processing without the distortions usually introduced by optical compressors.
