d&b audiotechnik has introduced its first amplifiers designed for permanent installation. The four channel, 2RU 10D and 30D amplifiers deliver 700W and 1600W per channel respectively, and share the same DSP platform and capabilities as the d&b D20 amplifier and the flagship D80.

Both models provide comprehensive d&b loudspeaker management and switchable filter functions, and incorporate two 16-band equalisers comprising parametric, notch, asymmetric and shelving filters along with up to 10 seconds of delay for each of the four channels. Between them they cover almost all install applications, differing only in output voltage and loudspeaker setups. The extensive DSP capabilities are also ready for further expansion via future d&b firmware updates.

To aid seamless integration into existing installations, the new models offer five programmable general purpose input /output pins, so external devices can be used for control or detection functions. They provide four analogue and four digital AES/EBU inputs, all of which can be summed and routed to any of the four outputs. This extended input matrix allows all eight inputs to be used simultaneously. In addition, each input features an independent input gain, which means various input sources with different levels, can be used without requiring an external mixing device. System status monitoring ensures suitability for sound reinforcement systems for emergency situations.

The devices can be accessed using either CAN-Bus, or via Ethernet using the Open Control Architecture (OCA) protocols. They are controlled using the d&b R1 Remote control software, which presents an entire system graphically, enabling the central control and management of a complete system. Password protection functions restrict access, and AmpPresets enable users to change predefined levels or configuration settings of devices. Alternatively, the 10D and 30D can be controlled using the integrated web interface, allowing individual amplifiers to be controlled using a browser window.

The 10D amplifier is intended for small applications with lower SPL requirements, making it ideal for bars, lounges and conference facilities with flexible room configurations. It features setups for all d&b loudspeakers except the large format flagship J-Series line array, the V-Series and the M2 monitor. The powerful 30D amplifier contains configurations for all d&b loudspeakers and is designed for medium to large applications with demanding SPL requirements.
