You don’t hear pumping or other audio artifacts, just natural sound that is evenly consistent in loudness. The Silence Gate immediately releases when the program material resumes. Reviews 0 Write a review. No Longer Available Update Location close. Be the first to review this item.

320D Compellor

The patented technologies within the D are totally unique. The stated purpose of this processor is to normalize match the output levels of low-level and high-level incoming signals. Extremely easy to operate, the user only needs to set the Drive level to generate the desired amount of processing, set the Cmopellor Balance control between Leveling and Compression and adjust the Output level for unity gain.

Playing irregularly–a few notes, then a rest, then a few more notes–also caused the automatic sensors to ccompellor overtime, which resulted in audible artifacts. Some Compellors have literally been in hour use in the same rack for a decade or longer!

Patented control circuits include analog computers that continuously analyze the input signal, and vary the control apehx to provide for virtually undetectable operation, regardless of the dynamics of the program.

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.

I also noted that the limiter was not so useful, it only kicked in on the most extreme peaks. The Compellot is then ready to provide complete dynamic control – smooth, inaudible compression, increased system gain, desired program density and the freedom from constant comellor riding” – all performed automatically. When the analog input is used, the digital output contains the D’s processing. The tone is completely transparent. When you listen, you know the levels are made more even, but you don’t perceive the levels are shifting.


The front panel metering system displays input level, output level 320z gain reduction levels. 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 delivers “intelligent” compressor action, leveling and peak limiting simultaneously.

It will try very hard to normalize an unruly signal, resulting 32a0 the noise level raising and dropping constantly. 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.

Not specified by manufacturer. The D can act as two independent mono processors or one linked stereo processor, which is selectable on the front panel.

comepllor In Stereo mode, the user can choose between linking only the leveling control signals or linking both the compression and leveling signals. Write a review fvzqbyxqudwyaxxu. I think the A version is discontinued, only available used. 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. Whereas with the more even-output bass, with 3320a playing, it was fairly easy to find a clean, natural-sounding, noiseless setting.

When you specify a Compellor, you know it will do its job flawlessly and give you peace of mind. With the active, the automatic levelling functions were trying so hard to regulate the signal that the vompellor level would jump up and down, and playing that B string hard caused a lot of distortion.

The D’s Frequency Discriminate Leveler section, ckmpellor 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. Update Unrecognized Zip Code. It works differently at different frequencies and stops processing when the sound stops, then resumes instantly when the sound reappears, so there’s apyex distracting increases in program background noise.


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.

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 complelor, this is a good tool for that purpose. With some careful experimentation I was eventually able to find a setting that worked decently compellor the hard-to-control bass with a minimum of artifacts, but it took some time.

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.

Aphex builds products that last and last without need for repairs or calibration. 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. I used it with two basses: 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 channels of processing. So it’s ideally suited to broadcast work.
