The Extron DMP 128 Plus is a next-generation 12×8 digital audio matrix processor featuring Extron’s ProDSP™ 64-bit floating point engine. It offers advanced audio routing and signal processing in a compact 1U, full-rack chassis.

Core analog I/O includes 12 balanced/unbalanced mic/line inputs (phantom-power on channels 1–8) and 8 line-level outputs, backed by full DSP processing per channel. USB-enabled models support up to four channels of digital audio I/O, recognized as a USB sound card. Optional variants provide VoIP support (up to eight SIP channels) and Dante audio networking with up to 48 Dante inputs and 24 outputs, plus Dante/AEC/VoIP integration as needed.

The architecture supports a large internal matrix: up to 84 inputs by 48 outputs, enabling flexible routing from analog, USB, virtual returns, Dante, or expansion ports and ACP panels.
