With some careful experimentation I was eventually able to find a setting that worked decently for the hard-to-control bass with a minimum of artifacts, but it took some time. The A delivers “intelligent” compressor action, leveling and peak limiting simultaneously. So it’s ideally suited to broadcast work.

All potentiometers are detented for accurate resetting of controls. Reviews 0 Write a review. Extensive compressor reviews and FAQ. So right at the outset, this unit is capable of far more advanced dynamics control than most other comps, but it can also be harder to use since the controls are unfamiliar and non-concrete.

The A is then aphxe to provide complete dynamic control – smooth, inaudible compression, increased system gain, desired program density and the freedom from constant “gain riding” – all performed automatically. The front panel metering system displays input level, output level or gain reduction levels.

When you aphe a Compellor, you know it will do its job flawlessly and give you peace of mind. This is a two-channel rackmount unit, and it’s quite different from the other comps I’ve reviewed. No other product can match the performance of the D. 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.

See any errors on this page? Playing irregularly–a few notes, then a rest, then compeloor few more notes–also caused the automatic sensors to work overtime, which resulted in audible artifacts. Write a review fvzqbyxqudwyaxxu.

In mono mode, unit provides two completely independent channels of processing. No Longer Available Update Location close.


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 aphez in live sound applications. So overall my impression is that this comp is a fantastic tool, which really does offer some valuable processing power and a super clean sound; but it is not well suited for use in any rig where the dynamics and signal peaks can vary wildly.

You don’t hear pumping or other audio artifacts, just natural sound that is evenly consistent in loudness.

Aphex Compellor 320a Dual Compressor Limiter Expander

Overview Tech Specs Gallery Downloads. Some Compellors have literally been in hour use in the same rack for a 32a0 or longer! 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 aphx the mix, this is a good tool for that purpose.

I think the A version is discontinued, only available used. 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 in program background noise. By going beyond conventional design ideas, the D provides audio processing with unprecedented sound transparency, yet is exceedingly effective at controlling levels. The patented technologies within the D are totally unique.

With the active, the automatic levelling functions were trying so hard to regulate the signal that the noise level would jump up and down, and playing that B string hard caused a lot of distortion. When the analog input is used, the digital output contains the D’s processing. I also noted that the limiter was not so useful, it only kicked in on the most extreme peaks.

Its unique circuit design actually enhances transient qualities, thus making even heavy processing undetectable.

Aphex builds products that last and last without need for repairs or calibration. It can also take a sloppy instrumental or vocal track and regulate it all to the same level. It combines compression, limiting, leveling, and gating, and those functions are all controlled in an interconnected way by an automatic “program adaptive” system.


The D’s limiter acts on peaks that shoot beyond average program levels so they are easy to handle by any analog or digital recording system.

It will try very hard to normalize an unruly signal, resulting in the noise level raising and dropping constantly.

I used it with two basses: 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.

The Silence Gate immediately releases when the program material resumes. You might say a steady, level signal doesn’t need any compression, but the processed signal is much more “present” and “energetic” sounding than the dry signal. Be the first to review cokpellor item. When you listen, aphexx know the levels are made more even, but you don’t perceive the levels are shifting. Extremely easy to operate, the user only needs to set the Drive level to generate the desired aphexx of processing, set the Process Balance control 3220a Leveling and Compression and adjust the Output level for unity gain.

The D can act as two independent mono processors or one linked stereo processor, which is selectable on the front panel.

The A provides the option of Dual Mono or Stereo operation.

Update Unrecognized Zip Code. The stated purpose of this processor is to normalize match the output levels of low-level and high-level incoming signals. In Stereo mode, the user can choose between linking only the leveling control signals or linking both the compression and leveling signals. 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.
