DMA8X8 is an audio matrix with 8 inputs/8 outputs, with remote control and monitoring through PC software, from remote panels or from configurable and customizable APPs, available for iOS or Android devices.
The DMA8X8 interface enables customers to perform centralized control of multiple devices. It also allows third-party equipment to be controlled through RS232, RS485 ports; The digital signal processor (DSP) includes multiple functions such as expander, compressor, limiter, automatic gain control (AGC), equalization, feedback suppression, echo cancellation (AEC), noise suppression (ANS), automix, etc.
DMA8X8
The DMA8X8 processor uses an ADI DSP SHARC 21489 chip, clocked at 450M Hz, 48kHz sampling rate, and 24bits.
DSP input and output modules can be customized according to the site conditions and needs.
With the DMA8X8 the audio processing needs in different spaces, such as conference rooms, multifunction rooms, conference centers, auditoriums, administrative centers, etc., will be fully satisfied.
In addition, it has a USB port that, connected to a computer, behaves like a sound card to play a music channel.
It also has two remote control panels (via Ethernet) configurable from software.
