The D’s Frequency Discriminate Leveler section, with the Dynamic Verification Gate and the Silence Gate, slowly adjusts the volume level of an audio stream with very complex algorithms that hide its work.
The Silence Gate immediately releases when the program material resumes. I compellorr noted that the limiter was not so useful, it only cimpellor in on the most extreme peaks. The A is then ready to provide complete dynamic control – smooth, inaudible compression, increased system gain, desired program density and the freedom from com;ellor “gain riding” – all performed automatically.
Update Unrecognized Zip Code. The D can act as two independent mono processors or one linked stereo processor, which is selectable on the front panel. 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.

When the digital input is used, the analog output contains the D’s processing, properly leveled. It can be used to solve audio level problems and improve audio coompellor in the broadcast or recording studio, tape duplication house, film-dubbing studio or in live sound applications.
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.
I used it with two basses: All potentiometers are detented for accurate resetting of controls. 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. Not specified by manufacturer. 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.
The stated purpose of this processor is to normalize match the output levels of low-level and high-level incoming signals. 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. 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.
Its unique circuit design actually enhances transient qualities, thus making even heavy processing undetectable.

So it’s ideally suited to broadcast work. The A provides the option of Dual Mono or Stereo operation. Whereas with the more even-output bass, with steadier playing, it was fairly easy to find a clean, compeolor, noiseless setting. Enter new zip code to refresh estimated delivery time. By going beyond conventional design ideas, the D provides audio processing with unprecedented sound transparency, yet is exceedingly effective at controlling levels.
I think the Aphrx version is discontinued, only available used. You don’t hear pumping or other audio artifacts, just natural sound that is evenly consistent in loudness.
The A delivers “intelligent” compressor action, leveling and peak limiting simultaneously. No other product can match the performance of the D.
When you specify compello Compellor, you know it will do its job flawlessly and give you peace of mind.
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. There is no rolloff of the lows, and the highs only roll off a bit at the highest compression settings.
When you listen, you know the levels are made more even, but you don’t perceive the levels are shifting. Reviews 0 Write a review. Playing irregularly–a few notes, then a rest, then a few more notes–also caused the automatic sensors to work overtime, which resulted in audible artifacts.
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. Some Compellors have literally been in hour use in the same rack for a decade or longer! The tone is completely transparent. Overview Tech Specs Gallery Downloads.
Aphex builds products that last and last without need for repairs or calibration. Extremely aphhex 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. With the passive, this comp really brought out the sound in a punchy, articulate way, with nice clear harmonics, and no compelkor noise or artifacts.
The front panel metering system displays input level, output level or gain reduction levels. When the analog input is used, the digital output contains the D’s processing.
It doesn’t generate any noise of its own, although like all zphex it compeellor amplify existing noise at higher cokpellor.
This is a two-channel rackmount unit, and it’s quite different from the other comps I’ve reviewed. 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.
It combines compression, limiting, leveling, and gating, and those functions are all controlled in an interconnected way by an automatic “program adaptive” system.
See any errors on ocmpellor page? Be the first to review this item. It will try very hard to normalize an unruly signal, resulting in the noise level raising and dropping constantly.
It can also take a sloppy instrumental or vocal track and regulate it all to the same level.

Copying is prohibited, but please feel free to link to this page using the link text “compressor reviews”. 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. The patented technologies within the D are totally unique.
