MDA Series Digital Amplifiers
The new MDA4000 Series of FBT power amplifiers combines a full matrix 4x4 DSP and features a flexible class-D power platform. Its compact and lightweight design makes it suitable to be used as a multi-zone application in small to medium-scale installations either in a stand-alone mode or in complex centralized audio systems. This series offers three 4-channels models (MDA4125, MDA4500 and MDA4800), with a total power from 500W to 3000W in either Hi-Z or Low-Z output configuration.
The MDA Series can meet the requirements of every speaker system, giving a dynamic listening experience and a more satisfying environment to be in. Also, FBT custom speaker libraries help the installer make the configuration workflow easy and quick. All models offer multiple analog and digital input options, built in wireless access point, wired LAN connection and programmable control inputs that can be used for remote control.
The Onboard Browser-Based Interface, built with the FBT intuitive user interface, makes it easier to control, configure and monitor the amplifier from a smartphone, tablet, or PC directly via web browser. There is no need to download a dedicated app since the user can easily communicate with the device via Ethernet port or built-in WiFi. The WiFi connection allows secure ID and password protection from unauthorized access. Moreover, advanced users will appreciate the custom IP settings allowed by the Ethernet connection, useful for a more complex wired LAN. The browser-based network interface also makes remote service and troubleshooting easier since a technician can simply log in with remote access from their PC or mobile device.
