d&b audiotechnik has announced the D20 power amplifier, offering an intuitive user interface, and remote control and monitoring via Ethernet through the Open Control Architecture (OCA) protocol.

The D20 has four independent 1.6kW channels, each with two 16-band equalisers featuring parametric, notch, shelving and asymmetric filters and up to 10s of delay. The dDSP power of the D20 means that external system processors are not required, reducing the equipment required in any given signal chain.

The amplifier’s user interface has a colour touchscreen along with a rotary encoder, and has an integrated web interface for use with a browser that provides control from d&b R1 Remote control software V2, which runs on Windows or Mac computers. R1 provides enhanced EQ functionalitiy, enabling users to freely define and manipulate EQ using a touchscreen or mouse and keyboard.

Four amplifier channels in a lightweight 2U-high package minimises the rack space required in installations as well as mobile applications and reduces transport costs. The D20 has the power and processing necessary for smaller d&b loudspeaker Series, such as the E-Series and T-Series. The Y-Series and V-Series can be driven by the D20, but to realise the loudspeakers’ full SPL potential they need to be powered by the d&b flagship amplifier the D80. A D80 amplifier is required to power the J-Series and the M2 monitors.

Thanks to the class D amplifier and a Switch Mode Power Supply with active Power Factor Correction (PFC) the D20 requires reduced input power and offers exceptional energy efficiency. The output capability of the D20 is largely independent from voltage variations caused by substandard electrical sources so the amplifier is able to maintain optimum system performance when running from heavily loaded mains supplies.

‘The D20 gives users the DSP power and field proven user interfaces of our flagship amplifier the D80,’ says d&b Product Manger, Marc Weber. ‘It is an ideal solution for smaller loudspeakers or systems and applications that don’t require the highest sound pressure levels. As such it is a versatile tool suitable for a wide range of applications.’
