Compressor/Limiters

Analogue Compressors and limiters are dynamic processing tools used in recording studios to control the dynamic range of audio signals. A compressor works by reducing the level of the loudest parts of a signal, while leaving the quieter parts unaffected. This can help to even out the overall volume of a recording and make it sound more consistent. Limiters work similarly to compressors, but they have a more aggressive ratio and a fixed threshold that won’t allow the signal to go above a certain level. This can be useful for preventing clipping or distortion when recording signals with a high dynamic range. In addition to controlling dynamic range, compressors and limiters can also be used creatively to add character and colour to a recording. For example, some compressors have a “vintage” or “analogue” sound that can add warmth or saturation to a recording, while others can provide a more transparent or clean sound. Some compressors even have specific settings for different instruments or types of signals, such as vocals or drums. Choosing the right compressor or limiter for a particular recording can be a crucial part of the mixing process, as it can greatly affect the final sound of the track.

dbx 160 Compressor/Limiter

The dbx 160 and 161 are single-channel compressor/limiters combining sophisticated technology and user-oriented features in a compact package. Unique circuit designs, such as true rms level-detection and feed-forward gain reduction, place the 160 and 161 in a completely different class from conventional compressor/limiters.

Urei LA-5 Audio Leveler

Urei introduced the Urei LA-5 Audio Leveler with the specific needs of sound reinforcement professionals in mind.
Released in 1977

Urei LA-4 Compressor/Limiter

The Urei LA-4 Compressor/Limiter can reduce the dynamic range of an audio signal, making it more consistent and balanced. The Urei LA-4 Compressor/Limiter can also limit the maximum level of the signal, preventing distortion and clipping.
Released in 1978

dbx 162 Compressor/Limiter

The dbx 162 compressor/limiter is one of the most iconic studio compressor/limiters to have ever graced a studio. The dbx 162 compressor/limiter is a stereo device using true rms level detection circuitry tor signal sensing and sophisticated voltage-controlled amplifiers as the gain control elements.
Released in 1979

Urei 1178 Stereo Compressor

The Urei 1178 compressor was introduced in 1979 by Universal Audio. It became a popular choice in recording studios during the late 1970s and throughout the 1980s, and it remains a sought-after vintage piece of audio equipment today.
Released in 1979

DBX 163 Compressor/Limiter

The dbx 163 and dbx 164 compressor/ limiters feature dbx’s Over Easy compression. Over Easy refers to a “soft knee” compression characteristic that provides virtually inaudible gain control at ratios up to infinite compression.
Released in 1980

dbx 165 Compressor/Limiter

The dbx 165 is a professional single channel compressor/limiter that features the new dbx Over Easy compression curve. The dbx Over Easy compression curve permits extremely smooth, almost inaudible compression due to the gradual change of compression ratio around the threshold, instead of the customary sharp threshold.
Released in 1982

Valley People 610 Dual Compressor/Expander

The Valley People 610 Dual Compressor/Expander is a versatile, high-quality dynamics processor offering dual-channel compression, expansion, and various advanced features for professional audio applications.
Released in 1982

dbx 165A Compressor/Limiter

The dbx 165A is a professional single channel compressor/limiter that features the new dbx Over Easy compression curve. The dbx Over Easy compression curve permits extremely smooth, almost inaudible compression due to the gradual change of compression ratio around the threshold, instead of the customary sharp threshold.
Released in 1982

dbx 160X Compressor

The dbx 160X replaced the now legendary dbx 160 (VU) and added the over easy compression of the dbx 165 and changed the form factor from the half rack size with wood side panels, to a single rack chassis.
Released in 1985

Boss RCL-10 Compressor Limiter

The Boss RCL-10 Compressor Limiter from 1985 provides four different high-performance functions integrated into a single unit.
Released in 1987
