The patented technologies within the D are totally unique. The Silence Gate immediately releases when the program material resumes. I also noted cmpellor the limiter was not so useful, it only kicked in on the most extreme peaks.
You don’t hear pumping or other audio artifacts, just natural sound that is evenly consistent 32a loudness. The D can act as two independent mono processors or one linked stereo processor, which is selectable on the front panel.
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. Some Compellors have literally been in hour use in the same rack for a decade apgex longer! When the digital input is used, the analog output contains the D’s processing, properly leveled.
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. 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 think the A version is 320s, only available used. The A provides the option of Dual Mono cmpellor Stereo operation.
It will try very hard to normalize an unruly signal, resulting in the noise level raising and dropping constantly. 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. I used it with two basses: See any errors on this page?
All potentiometers are detented for accurate resetting of controls. By going beyond conventional design ideas, the D provides audio processing with unprecedented sound transparency, yet is exceedingly effective at controlling levels.

In Stereo mode, the user can choose between linking only the leveling control signals or linking both the compression and leveling signals. No other product can match the performance of the Apphex. Not specified by manufacturer. Its unique circuit design actually enhances transient qualities, thus making even heavy processing undetectable. On the other hand if your technique and signal are already fairly even, and compelloe 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’s Frequency Discriminate Leveler section, with the Dynamic Verification Gate and the Silence Gate, slowly adjusts the volume level of an audio stream with compelloor complex copellor that hide its work. It can also take a sloppy instrumental or vocal track and regulate it all to the same level. 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.
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 apphex signal. In mono mode, unit provides two completely independent channels of processing.
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; 3200a it is not well suited for use in any rig where the dynamics and signal peaks can vary wildly. When you specify a Compellor, you know it will do its job flawlessly and give you peace of mind.
Update Unrecognized Zip Code. 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.
It works differently at different frequencies and stops processing when the sound stops, then resumes instantly when the sound reappears, so there’s conpellor distracting increases in program background noise.
RJ connector on the rear panel facilitates remote relay bypass of the unit Co,pellor 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 tone is completely transparent.
Overview Tech Specs Gallery Downloads. There is no rolloff of the lows, and the highs only roll off a bit at the highest compression settings.

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. When the compelor input is used, the digital output contains the D’s processing.

Extensive compressor reviews and FAQ. This is a two-channel rackmount unit, and it’s quite different from the other comps I’ve reviewed. Whereas with the more even-output bass, with steadier playing, it was fairly easy to find a clean, natural-sounding, noiseless setting. The A is then ready to provide complete dynamic control – smooth, inaudible compression, increased system gain, desired program apgex and the freedom from constant “gain riding” – all performed automatically.
Compel,or builds products that last and last without need for repairs or calibration. The front panel metering system displays input level, output level or gain reduction levels. 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.
It combines compression, limiting, leveling, and gating, and those functions are all controlled in an interconnected way by an automatic “program adaptive” system. The stated purpose of this processor is to normalize match the output levels of low-level and high-level incoming signals. It doesn’t generate any noise of its own, although like all compressors it can amplify existing noise at higher settings.
