With some careful experimentation I was eventually able to coompellor a setting that worked decently for the hard-to-control bass with a minimum of artifacts, but it took some time.

It doesn’t generate any noise of its own, although like all compressors it can amplify existing noise xompellor higher settings. With the active, the automatic levelling functions were trying so hard to regulate the signal that the noise level would jump up comlellor down, and playing that B string hard caused a lot of distortion. The A provides the option of Dual Mono or Stereo operation.

When the digital input is used, the analog output contains the D’s processing, properly leveled. On the other hand if your technique and signal are already fairly even, and you just want to enhance the punch and harmonics, and set your place in the mix, this is a good tool for that purpose.

The D can act as two independent mono processors or one linked stereo processor, which is selectable on the front panel. I think the A version is discontinued, compellof available used.

320D Compellor

Extremely easy to operate, the user only needs to set the Drive level to generate the desired amount of processing, set the Process Balance control between Leveling and Compression and adjust the Output level for unity gain.


I also noted that the limiter was not so useful, compellpr only kicked in on the most extreme peaks. The tone is completely transparent. Update Unrecognized Zip Code. Its unique circuit design actually enhances transient qualities, thus making even heavy processing undetectable. This is a two-channel rackmount unit, and it’s quite different from the other comps I’ve reviewed.

Some Compellors have literally been in hour use in the same rack for a decade or longer! The front panel metering system displays input level, output level or gain reduction levels. Playing irregularly–a few notes, then a rest, then a few more notes–also caused the automatic sensors to work overtime, which resulted in compwllor artifacts.

No Longer Available Update Location close. With the passive, this comp really brought out the sound in a punchy, articulate way, with nice clear harmonics, and no noticeable noise or artifacts.

Aphex A COMPELLOR – Dual Channel Compressor/Limiter A B&H

RJ connector on the rear panel facilitates remote relay bypass of the unit A Silence Gate feature detects significant gaps in the program material and freezes the processing, thus preventing noise “swell” or “build-up”, a condition commonly audible in other automatic gain control devices. Whereas with the more even-output bass, with steadier playing, it was fairly easy to find a clean, natural-sounding, noiseless setting.

dompellor The patented technologies within the D are totally unique. Patented control circuits include analog computers that continuously analyze the input signal, and vary the control characteristics to provide for virtually undetectable operation, regardless of the dynamics of the program. All compellog are detented for accurate resetting of controls. There is no rolloff of the lows, and the highs only roll off a bit at the highest compression settings.

It can be used to solve audio level problems and improve audio signals in the broadcast or recording studio, tape duplication house, film-dubbing studio or in live sound applications.


The stated purpose of this processor is to normalize match the output levels of low-level and high-level incoming signals. No other product can match the performance of the D.

It combines compression, limiting, leveling, and gating, and those functions are all controlled in an interconnected way 32a0 an automatic “program adaptive” system. Aphex builds products that last and last without need for repairs or calibration. The A delivers “intelligent” compressor action, leveling and peak limiting simultaneously. Extensive compressor reviews and FAQ. It works differently at different frequencies and stops processing when the sound stops, then resumes instantly when the sound reappears, so there’s no distracting increases compelllr program background noise.

Enter new zip code to refresh estimated delivery time. It will try very hard to normalize an unruly signal, resulting in the noise level raising and dropping constantly. When the analog input is used, the digital output contains the D’s processing.

So right at the outset, this unit is capable of far more advanced dynamics control than most other comps, but aphed can also be harder to use since the controls are unfamiliar and non-concrete. In Stereo mode, the user can choose between linking only the leveling control signals or linking both the compression and leveling signals. The A is then ready to provide complete dynamic control – smooth, inaudible compression, increased system gain, desired program density and the freedom from constant “gain riding” comlellor all performed automatically.

So it’s ideally suited to broadcast work.
