Chepman 2254B is a classic (Class A) compressor. Assembled manually on discrete elements (without microchips and surface mounting) and tested with high quality standards.
Symmetrical transformer input, input impedance 10kOm. An interstage transformer separates the VCA and the amplifier unit. The output amplifier operates in Class A and is loaded onto a full-size transformer providing a balanced output.
Honest ByPass. The relay directs the signal from the input to the output bypassing the compressor circuit. When turned off, the device switches to ByPass mode.
Based on the circuitry of classic studio compressors of the 60 - 70s, which can be heard in countless hit recordings, the 2254B will add analog warmth to your signal, so necessary in modern digital studios. Efficiently and delicately works with any signal from drums and bass to vocals. Works great in master sections.

Historically, 2254 has been limited in settings. Fixed attack time (5ms), recovery time from 400ms. Therefore, when choosing a tire compressor, people tended to his brother – 33609, which had more flexibility of settings, but already worked in the AB class. The compression control scheme, in fact, was a natural development of the 2254 control. The changes were small and concerned only the addition of additional missing modes and the possibility of more precise factory settings. Our 2254B combines the best of these two legendary devices. Sound path in Class A and more functional control 33609. In addition, without changing the historical scheme, we added an adjustment of the attack time, which is not present in any of the progenitors. When the power is turned off, the device switches to True Bypass mode.
Chepman 2254B is a classic compressor with a diode level control unit. He started his life as a module in the legendary mixing consoles of the early 70s. Has its own signature colored sound, which is described as rich thick and round.
The advantages of Class A are manifested with any instruments and voices where warmth and a filled lower middle are required. Does a great job with vocals, skinny or too bright recordings. As a tire compressor, it stitches the mix well, glues together separately sounding instruments. When writing in conjunction with 1073, it gives a complete source code, perfectly amenable to further revision (if necessary to solve artistic problems).
