d&b audiotechnik has introduced its newest four-channel, 2 RU amplifiers at InfoComm 2015: the 10D and 30D.
The first d&b amplifiers tailored for permanent integration, the 10D and 30D deliver 700W and 1600W per channel respectively and share the same Digital Signal Processing (DSP) platform and capabilities as the d&b D20 amplifier and the flagship D80. These amplifiers all provide ‘comprehensive’ d&b loudspeaker management and switchable filter functions. They incorporate two 16-band equalisers comprising parametric, notch, asymmetric and shelving filters along with up to ten seconds of delay for each of the four channels. Between them they promise to cover almost all install applications, differing only in output voltage and loudspeaker setups. DSP capabilities are also ready for further expansion via future d&b firmware updates.
To ensure integration into existing permanent installations, the10D and 30D amplifiers offer five programmable General Purpose Input / Output pins, meaning external devices can be used for control or detection functions. They provide both four analog 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.
These 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, suitable 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 30D amplifier contains configurations for all d&b loudspeakers and is designed for medium to large applications with demanding SPL requirements. The 30D is suitable for all medium sized venues including stadiums, nightclubs, musical theatres, houses of worship and town halls.
“These new devices answer the demands for a d&b amplifier designed specifically for installations,” said product manager Wolfgang Schulz. “The predictable results from our highly appreciated mobile systems are now available for fixed installations, with very cost effective and efficient results.They offer a new price to performance for our installation customers and the d&b sound quality, reliability and flexibility that everyone has come to expect.”
