The DPA880T is a high performance 8 input x 8 output digital Matrix mixer. Designed for maximum versatility, it provides all the processing and control necessary for fixed installation use. Particularly suitable for conference system applications and other applications with multiple microphones and loudspeakers. It includes 8 independently switchable Line/Mic inputs with Phantom power supply, 8 Line outputs, managed by a powerful MARANI® DSP Engine, in addition to high performance 24 Bit AD/DA converters. The DPA880T supports a full matrix mixing mode where inputs may be routed/mixed in any ratio to any output. Each Mic/Line input channel provides Low/High-Pass 1st order filters, 3-band Parametric EQ, Noise Gate function and Gain control. In addition Mic inputs include a Feedback Eliminator function, based on a powerful “Pitch Shifting” algorithm, particularly suitable for voice applications. Each output offers up to 5-band of parametric equalization, in addition to the crossover filters which themselves provide slopes from 6dB/Octave upto 24dB/Octave. Each output path also features RMS compressor, Peak Limiter and configurable Delay. For remote configuration and control the DPA880T can be connected via Ethernet, USB or RS485 by using the control remote PC software. In addition, it can be managed by an Apple iPad® device, using the dedicated DPA880xT software setting all parameters For complex systems, 4 digital Input and 4 digital output ports are provided for GPIO Integration allowing connection to various devices. Furthermore the DPA880T can be connected via RS485 to the optional CP4 Wall Panel control that allows selection of 4 assigned presets and master volume control.
