Projects > AC Sound PI3141 PWM PYE Compressor
Pulse width modulation (PWM) is a rarely employed gain-reduction technique by which signals above the threshold are “chopped” using a high-frequency pulse. AC Sound’s PI3141 is a reproduction of a classic PYE compressor that utilized this technology.
Notable Features:
- Decay, limit (threshold), and ratio controls
- Class A operation
- Transformer balanced
- Stereo linking capability
Price: $55 for PCB
