About TOA Electronics M-864D

How does the M-864D 4U Rack-Mount Digital Stereo Mixer with ARC and FBS stand out in the world of professional audio equipment This high-performance mixer, designed to be rack-mountable in a 4U space, offers a robust 22 input channels. This includes 8 monaural input channels and 7 stereo input channels, providing ample connectivity for a variety of audio sources.

The M-864D also boasts 6 output channels, comprising 4 monaural output channels and 1 stereo recording output channel, along with 4 bus channels. This ensures versatile routing and output options to meet the demands of complex audio setups.

What sets this digital stereo mixer apart is its advanced digital signal processing functions. The Automatic Resonance Control (ARC) function measures the acoustic characteristics inherent in architectural space and automatically creates a filter curve to enhance sound clarity. The Feedback Suppressor (FBS) function helps to eliminate unwanted noise, while the Automatic Stereo Input Mute function (AUTO MUTE or Ducker) and Equalizer further refine the audio output.

The M-864D is designed for intuitive operation, featuring various function setting buttons and 14 analog volume faders. This allows for hands-on control without the need for a PC. However, for those who prefer digital control, the mixer can also be operated by connecting to a PC or an optional remote control panel.
