In addition to compression, the U23M also includes a built-in limiter. This allows you to ensure that your audio stays within safe levels, preventing clipping and distortion. The limiter can be engaged or disengaged independently of the compressor, giving you even more control over your audio.
The U23M is housed in a solid, aluminum chassis, with high-quality, gold-plated input and output connectors. It is a high-end, professional-grade compressor/limiter that is suitable for use in both studio and live applications.
In summary, the Vacuvox U23M Mastering Vari-Mu Compressor/Limiter is a versatile and powerful audio processing tool that delivers a unique and musical sound.
