Product Overview

The DPA880AMT is a high performance 8 input x 8 output digital Matrix mixer. Designed for conference systems, it maintains the same characteristics as the DPA880T in addition to the Automixing function and Ducking process. 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 DPA880AMT 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 microphone inputs include a Feedback Eliminator function, based on a powerful “Pitch Shifting” algorithm, particularly suitable for voice applications. Automixing function automatically adjusts input level to make operating easier using either NOM (Number of Open Mics) attenuation function or Gain Sharing algorithm. In addition Ducking process enforces a “priority order” of open microphones in order that high priority inputs attenuate lower-priority inputs. Each output offers up to 5-band of parametric equalization, crossover filters, RMS compressor, Peak Limiter and configurable Delay. For remote configuration and control the DPA880AMT 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 and showing real time levels. For complex systems, 8 digital IN/OUT ports are provided for GPIO Integration. Furthermore the DPA880AMT can be connected via RS485 to the optional CP4 Wall Panel control that allows selection of 4 assigned presets and master volume control.
