Monitor 8 is a 24 x 16 x 8 monitor mixer, 6-channel headphone amplifier and USB/AVB audio interface with console-style 48-channel mixing and DSP effects. Monitor 8 can mix 24 inputs, multichannel computer audio, and dozens of AVB audio network channels to eight stereo busses: Main, Aux and monitor groups A thru F.
The Monitor 8 can operate as an audio interface for a studio workstation (DAW), as a standalone mixer, or as an auxiliary monitor mixing system in the studio or on stage. The following sections provide a brief overview of its main features and characteristics. State-of-the-art A/D and D/A conversion Monitor 8’s analog section employs state-of-theart 24-bit DACs or ADCs, which deliver analog recording and playback with remarkably high dynamic range at sample rates from 44.1 to 192 kHz. Complementary I/O configurations Monitor 8 delivers an exceptional amount of analog and digital audio I/O. In addition, it is designed to complement MOTU’s other AVBequipped audio interfaces, to deliver a wide range of I/O options.
You can mix and match several interfaces and operate them as a unified I/O and mixing system. The following sections provide a bird’s-eye glance of the I/O configurations offered by each interface in the MOTU AVB family. Each interface provides a variety of analog and digital interconnects, all active simultaneously, designed to provide everything you need for a well equipped recording studio.
