FORMULA SOUND
Formula Sound AVC-2D Digital Noise Limiter
The Formula Sound AVC2D analogue signal processing digital control noise limiter gives full control of music levels without compromising the audio quality. Installation is very straightforward with just a couple of cables to plug in and is usually a DIY task.
TheAVC2D automatically adjusts the volume once a preset threshold has been reached to keep the audio level within that required. When attenuating the audio signal the distortion from the AVC2-D is less than 0.01% so the quality of the audio is not compromised.
PLEASE NOTE: This product is usually only suitable when the sound system is permanently installed in the venue. For venues where DJs or bands use their own equipment, the Sentry Noise Limiter (click here for details) is required.
