1. Compressed Air Supply The compressed air supplied by the com-pressor (1) flows to the air dryer (3) via the unloader (2) which automatically con-trols the pressure within the system with-in a range of between 7.2 and 8.1 bar, for instance. In the air dryer, the water va-pour in the air is extracted and expelled through the air dryer’s vent.
This design demonstrates a full-blown compressor/limiter with some neat bells and whistles. With a THAT 4301 at its heart, excellent performance is coupled with reduced parts count and minimal cost. A non-linear capacitor circuit is used to provide low distortion for slow moving signals, but
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,
COMPRESSORS 2017 MEI Corporation 261 To select the correct A6 compressor it is necessary to identify which head type is being used for system protection. High Pressure Switch Type compressors have a switch socket with a small off-centered port to allow sensing of pressure from the high pressure side of the compressor.
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
This document is intended to assist the service technician in the operation, maintenance and repair of the 3630 Compressor/Limiter and the NanoCompressor. Together with the 3630 and NanoCompressor Reference Manuals, this document provides a complete description of the functionality and serviceability of these units.
With the Attack control set to minimum you can see the compressor clamping down on the signal within 3 milliseconds. For guitar this is almost instant, making notes sound more uniform and fluid.
