The DPA880AMT is a high-performance digital audio matrix with 8 inputs and 8 outputs. Designed specifically for audio conference systems, keeps the same characteristics of the DPA880T with the addition of car mixing and ducking functions. It includes 8 individually switchable inputs such as line or mic with phantom power and 8 line outputs, all managed by a powerful DSP together with high-performance AD / 24bit converters. The DPA880AMT supports "Routing" mode in which the inputs can be routed / mixed in any output. Each MIC / LINE input channel provides pass filters-high and pass-bass 1° Order, 3-band parametric equalizer, Noise gate function and gain control. Furthermore, the microphone inputs include the Feedback Eliminator function, based on a powerful "pitch shifting" algorithm, particularly suitable for "voice" applications. Automixing function automatically adjusts the input level, to make the management easier thanks to both the nom (open microphone number) function, and to the gain sharing algorithm. In addition, the "Ducker Priority" function imposes a "priority order" to open microphones, so that the high priority inputs attenuate those inputs at low priority. Each output offers up to 5 parametric equalization bands, crossover filters, RMS compressor, peak limiter and programmable delay. The DPA880AMT can be connected via USB, Ethernet or RS485 for remote and control configuration, using the dedicated PC software that also allows setting of all parameters and viewing all levels in real time. Additionally, the matrix can also be managed by the Apple iPad® device, using DPA880XT dedicated software that allows you to intervene on all control and management parameters. For the application in complex systems, the matrix also provides 8 digital ports in / out (GPIO) for integration with other devices. Finally, the DPA880AMT can be connected through the RS485 connection to the optional CP4 remote control panel that allows the selection of 4 assigned presets and control of the master volume.
