MDA88F is a highly Fexible and intelligent digital audio matrix mixer with 8-Channel Class D power amplifier delivering up to a total of 2000W@4O. To guarantee maximum reliability, it includes 2 highly efficient Switch Mode Power Supplies with PFC, each independently powering a set of 4 channels. The 8 output stages use the well-known Class D - full bandwith PWM modulator obtaining ultra low distortion, high efficiency and also equipped with a full set of circuit protections. Designed to meet the most demanding multizone application sound systems, it provides a full set of value added features such as 8 independently switchable Line/Mic inputs with Phantom power supply, 8 Line outputs, supporting a full matrix mixing mode where inputs may be routed/mixed in any ratio to any output. MDA88F also provides a variety of Eqs, Noise Gate function, Gain control, X-over, RMS compressor, Peak Limiter and Delay. In addition Mic inputs include a Feedback Eliminator, 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 Mics in order that high-priority inputs attenuate lower-priority inputs. For remote configuration and control the MDA88F 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 MDA88F can be connected via RS485 to the optional CP4 Wall Panel control that allows selection of 4 assigned presets and master volume control. Collapse text
