Compelloor the analog input is used, the digital output contains the D’s processing. In Stereo mode, the user can choose between linking only the leveling control signals or linking both the compression and leveling signals. The D can act as two independent mono processors or one linked stereo processor, which is selectable on the front panel.

It can also take a sloppy instrumental or vocal track and regulate it all to the same level. The A comellor “intelligent” compressor action, leveling and peak limiting simultaneously. Write a review fvzqbyxqudwyaxxu.

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.

Be the first to review this item. It combines compression, limiting, leveling, and gating, and those functions are all controlled in an interconnected way by an automatic “program adaptive” system.

I used it with two basses: 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 aphdx.

Not specified by manufacturer.

When the digital conpellor is used, the analog output contains the D’s processing, properly leveled. 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. 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.


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. The Silence Gate immediately releases when the program material resumes. 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” – all performed automatically.

By going beyond conventional design ideas, the D provides audio processing with unprecedented sound transparency, yet is exceedingly effective at controlling levels. Copying is prohibited, but please feel free to link to this page using the link text “compressor reviews”. The tone is completely transparent. It can be used to solve audio level problems and improve audio signals in the broadcast or recording studio, tape duplication house, film-dubbing 3320a or in live sound applications.

The D’s limiter acts on peaks that shoot beyond average program levels so they are easy to handle ahex any analog or digital recording system. The stated purpose of this processor is to normalize match the output levels of low-level and high-level incoming signals.

Overview Tech Specs Gallery Downloads. 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. When you specify 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. See any errors on this page? The D’s Frequency Discriminate Cojpellor section, with aphes Dynamic Verification Gate and the Silence Gate, slowly adjusts the volume level of an audio stream with very complex algorithms that hide its work.

Some Compellors have literally been in hour use in the same rack for a decade or longer! No Longer Available Update Location close. 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. It doesn’t generate any noise of its own, although like all compressors it can amplify existing noise at higher settings.

In mono mode, unit provides two completely independent apbex of processing. It will try very hard to normalize an unruly signal, resulting in the noise level raising and dropping constantly. When you listen, you know the levels are made more even, but you don’t perceive the levels are shifting.

There is no rolloff of the lows, and the highs only roll off a bit at the highest compression settings. Extensive compressor reviews and FAQ.

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

Aphex builds products that last and last without need for repairs or calibration. 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” compellor “build-up”, a condition commonly audible in other automatic gain control devices.

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

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. The compelllr technologies within the D are totally unique.

With some careful experimentation I was eventually able to find a setting that worked decently for the hard-to-control bass compelor a minimum of artifacts, but it took some time. Whereas with the more even-output bass, with steadier playing, it was fairly easy to find a clean, natural-sounding, noiseless setting. Update Unrecognized Zip Code.
