The d&b D40 amplifier is a mobile specific four channel amplifier with maximum output power of 4 x 2400/2000 W into 4/8 Ω. This four channel Class D mobile amplifier provides the power density required for high-efficiency d&b systems including the KSL System, V-Series, Y-Series and T-Series.

Features
Maximum output power – 4 x 2400/2000 W into 4/8 Ω
Maximum output voltage/current – 180 Vpeak / 35 Apeak
Operating and Monitoring display, Colour TFT touchscreen, 4.3″ / 480 x 272 pixel
Drives all current d&b loudspeaker setups except GSL, SL-SUB, J-Series, M2

The D40 incorporates comprehensive loudspeaker management, switchable filtering functions as well as user definable equalization and delay capabilities.

Onboard enhanced energy saving features, power efficiency and Automatic Wake up enable you to save on resources and meet environmental responsibility requirements.

The D40 incorporates up to eight input channels with four analogue inputs and four AES3 channels with corresponding link outputs. Each input channel can be routed to any of the output channels.

The D40 utilises a switch mode power supply with automatic mains range selection and active Power Factor Correction (PFC) to produce a clean current draw and ensure stable and efficient performance under adverse mains conditions.

Access to the d&b Remote network is via Ethernet using the Open Control Architecture protocol (AES70 / OCA). The D40 is controlled using the integrated web interface, which enables access via a browser, or using the d&b R1 Remote control software.

For applicable d&b loudspeakers, d&b LoadMatch enables the D40 amplifier to preserve tonal balance when cable lengths of up to 70 m (230 ft) are used.
