Description

d&b audiotechnik 40D Amplifier Installation Specific Four Channel Amplifier

The d&b audiotechnik 40D is a 2RU installation amplifier features integrated DSP with comprehensive loudspeaker management, switchable filters, and parametric EQ capabilities.

The amps has a 4.3" colour touchscreen, which allows for intuitive configuration and real-time system diagnostics.

The 40D includes flexible input routing, supporting 8 Milan network, 4 analogue, and 4 AES3 inputs, plus GPIO integration for building control systems. LoadMatch technology compensates for cable losses of up to 70 m while maintaining tonal accuracy. Remote configuration via AES70/OCA and R1 software also streamlines deployment and ongoing management.
