D&b D20: Four-channel amplifier with DSP power and remote control functions

The four-channel amplifier d&b D20 offers the power of DSP and is an ideal solution for small speakers or systems and applications that do not require very high sound pressure levels.

d&b Audiotechnik has unveiled its new two-rack unit amplifier (2RU) and four D20 channels. Includes proven, intuitive user interfaces and offers fast, responsive remote control and monitoring capabilities over Ethernet using the Open Control Architecture protocol (OCA).

The D20 amplifier, that&b Audiotechnik presented in the last edition of Prolight+Sound held in Frankfurt, It has four independent channels of 1600 watts, each with two equalizers 16 bands offering parametric filters, notch, shelving and asymmetrical, and even 10 seconds delay. Digital signal processing power (DSP) of the D20 amplifier means no processors are needed for the external system, which reduces equipment in the signal chain.

The amplifier's intuitive user interface includes a color touch screen along with a rotary encoder. They are activated with an integrated web interface for use with a browser and can be controlled using d's R1 remote control software.&b v2, running on Windows or Mac. R1 software provides enhanced equalization capabilities that allow you to freely set and operate the EQ using the touch screen or mouse and keyboard..

With four amplifier channels in a lightweight 2RU unit, the rack space required is minimized, both in installations and in mobile applications, and transportation costs are also reduced.

The D20 offers all the power and processing that D series speakers need.&b smaller, such as E Series and T Series. The Y Series and V Series can be powered by the D20, but to get the full SPL potential of the speakers, must be powered by d's flagship amplifier&b D80. A D80 amplifier is required to drive the J Series and M2 monitors..

Thanks to the class D amplifier and switching power supply with active power factor correction (PFC), The D20 requires lower input power to offer greater energy efficiency. The output capacity of the D20 is independent of voltage variations caused by electrical sources of irregular performance, so the amplifier can maintain optimal system performance when operating on high load power supply.
