Description:
American FET | A 500-series FET compressor that helped define the sound of American records.
Overview:
* Every original hardware unit was measured at the factory before shipping—documented with specific readings, noting whether or not they met the standard. American FET is calibrated according to these same specifications, matching all six settings in both Compress and Limit modes.
* Listen before you buy. Try it out: compare the hardware to the plug-in—with levels matched so that neither sounds louder than the other—and decide for yourself.
* One knob does it all. The CEILING control compresses the signal while automatically compensating for the gain, ensuring your output level remains consistent with your input.
* Add character, even when the compressor is bypassed. In OFF mode, the discrete amplifier and transformer remain in the signal path, lending a “console-like” weight to tracks that don’t require compression.
* The circuitry remains active as long as audio is passing through it—featuring a JFET (junction field-effect transistor), discrete op-amps acting as transistor stages, and a custom-designed transformer.
It’s fast. A JFET handles the gain reduction, capturing transients before they fully develop, while the discrete op-amps in the signal path add their own unique color during operation. Place it on a room mic, and distance transforms into weight; it finds the perfect “stick” in the snare sound. On vocals, it holds the line—without ever sounding like it’s actually holding anything back.
There’s a reason this design remains a staple in racks that are already packed with three other compressors. It’s not about subtlety here. Drums sound like a finished record rather than a raw session take—they command presence from across the room, rather than fading into the background after a few bars.
Down to the individual components:
* The CEILING steps are derived from a resistive ladder network—2 dB per step, measured based on the actual components rather than a theoretical curve.
* The D-S (de-essing) sidechain filter is modeled separately from the switching network, including a detail often overlooked: it boosts both low and high frequencies.
* The output transformer is identical to the original, modeled using the same core material. It introduces genuine saturation, not just a simple increase in volume.
* The detector reconstructs inter-sample peaks at approximately 380 kHz—independent of your system’s sample rate—ensuring that fast transients are captured even where a standard digital detector would show a low level.
Every aspect is accounted for, including the nuances where the model still differs from the specific hardware unit measured.
Color without compression
Switch the mode to OFF, and while the gain-reduction cell is bypassed, the discrete output amplifier and transformer remain in the signal path. In this state, the OUT control functions as a tone control rather than a simple volume knob; push it, then adjust the TRIM control to set your desired output level.
When working with a quiet source, this signal path remains clean. Feed a “hot” track into it and engage the OUT setting; the compressor kicks in, with the third harmonic significantly outpacing the second—much like the saturation behavior of a push-pull output stage. It adds the “weight” of a mixing console to a track that might not even need compression. Most compressors force you to choose between two extremes; this one doesn’t.
What you get:
* Four modes: C (2:1 compression that stays unobtrusive), L (20:1 limiting that clamps the signal down), OFF (amplifier and transformer coloration without dynamics processing), and BYP (true bypass).
* CEILING: the only control you need for compression. A single turn takes you from gentle, two-decibel compression all the way to full-on limiting.
* Four selectable attack/release timing options on the front panel, ranging from 0.1s to 2.5s.
* D-S: shifts the detector toward the high-frequency range, effectively turning the unit into a de-esser for vocals—no extra plugin required.
* External sidechain, Dual/Stereo-link/Mono modes, a Dry/Wet mix for parallel processing, and a post-transformer TRIM control, allowing you to drive the amplifier while keeping your output levels in check.
* A peak-reduction display beneath the meter, showing you exactly how much gain reduction is being applied.
What sets it apart: PCCN™
Traditional DSP models simulate the *result*—a fixed saturation curve, an impulse response, or a “snapshot” of behavior captured at a single point in time. PCCN simulates the *cause*: the circuit itself dynamically adjusts as the audio signal passes through it. You hear nuances that a static curve simply cannot replicate. The “knee” emerges from the rectifier stage within the detector; the slope increases as the available headroom in the amplifier cell runs out, while the output transformer responds to an incoming signal sooner than the amplifier does.
