TOA D-901 Modular Digital Mixer

TOA D-901 Modular Digital Mixer

For a wide range of installed sound applications, including audio/visual, houses of worship, and many more, the D-901 DIGITAL MIXER is the perfect choice. Up to twelve mic/line inputs and eight line outputs can be supported by the D-901's modular design, which allows for flexible RS-232 or contact-closure remote control. Auto-mixing, feedback suppression, multi-band parametric filters, compressors, limiters, noise gates, crossovers, delays, and other techniques are used in audio processing. For multi-zone or room-combining applications, full input-to-output matrixing enables users to save and remember any input-to-output combination. The device can be configured either on-site using PC management software or through the front panel display.
