LD Systems VIBZ 12 DC - analogue mixer with 12 channels, featuring DFX and a compressor. It offers 6 balanced microphone inputs with preamplifiers, a low-cut filter, integrated compressor, 100 digital effects with 24-bit resolution, 3-band EQ, and selectable phantom power. The 4 microphone channels can be processed separately using the built-in compressor for better dynamic management. The other two channels can alternatively be used as stereo line channels. The remaining stereo channels are equipped with 2-band EQ.
The main section provides two effect loops, balanced XLR outputs, group and monitor outputs, and a headphone output. It also includes RCA connectors for external playback and recording devices, buttons for PFL and mute functions.
