TOA D901
The D-901 DIGITAL MIXER is the ideal solution for a wide variety of
installed sound applications including audio/visual, houses of worship
and many others. The D-901’s modular design supports up to twelve
mic/line inputs and eight line outputs with flexible RS-232 or contact-
closure remote control. Audio processing tools include auto-mixing,
feedback suppression, multi-band parametric filters, compressors,
limiters, noise gates, crossovers, delays and more. Full input-to-
output matrixing allows users to store and recall any input to output
combination for multi-zone or room-combining applications. The unit
can be programmed via the front panel display or configured off-site
with PC control software for later uploading.
