The UREI 1176 Peak Limiter is a classic audio compressor designed by Bill Putnam, first built in 1967, making use of FETs and using them as a variable resistor to control the gain reduction in the circuit. The 1176 has been employed in countless recordings over the years and it is still used by almost every recording studio...

compressor/limiter designs. This application note describes in detail the circuitry for two basic com-pressor/limiter designs using these devices. The first design is an above-threshold, hard-knee compressor with variable ratio, thresh-old and gain controls. The second design adds a soft-knee threshold. Suggestions for alignment are
The schematic shown in Figure 1 is a basic soft-knee compressor/limiter circuit that can be used as-is or as the basis for a more sophisticated design. The circuit consists of a THAT2180C VCA, a THAT2252 RMS level detector, a few op-amps, and a handful of passive components. An alternative would be to use a single THAT4301 (which comprises the VCA,
A VCA (voltage controlled amplifier/ attenuator) is the heart of any compressor or peak limiter circuit, and there are quite a few different approaches. All available circuits have limitations, and this article looks at the various techniques used.
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.
