Manley Stereo Variable Mu limiter a kompresor

The Manley Stereo Variable Mu is a classic all-tube compressor/limiter that delivers the legendary warmth and musicality of Variable Mu technology. Designed for stereo bus, mastering, and tracking applications, this 2U rack unit combines four 6BA6, two 6V6, one 5670, and one 12AT7 tubes to provide rich harmonic saturation and smooth gain reduction. With variable attack (25ms to 70ms), release (0.1s to 5s), and compression ratio (1.5:1 to 10:1), it offers precise control over dynamics. The unit features both Compress and Limit modes, internal or external sidechain, and large VU meters for input, output, and gain reduction. Balanced XLR inputs and outputs ensure professional connectivity. The internal power supply is selectable for worldwide voltage.
