Easyrider Aphex Model 106 Operation not confirmed due to the absence of a power cord. Product Description Translation This is a compressor with a reduced control set. The panel space saved by omitting some of the standard features allows for an additional channel pair in a 1U rack space—yes, this is a 4‑channel compressor! Using two of these units, the entire output of a Fostex R8, Alesis ADAT, or Tascam DA‑88 can be compressed, and with the right amount of taste and common sense applied, your mixes can sound more professional. But wait a minute, you say, you said that some of the controls normally found on a compressor are missing. Doesn't that mean you won't be able to properly control the compression effect? Not really. While you can't have precise control like a Drawmer DL221 compressor, Aphex has condensed the essential functions of a compressor into a very small control set. A full‑spec compressor has five rotary controls and at least one switch per channel (threshold, ratio, attack, release, gain, bypass switch), but the Aphex Model 106 has drive, output, fast/slow, and on/off controls—only two rotary controls per channel in total, but as we'll explain, they do the job.
