At InfoComm 2015 d&b audiotechnik introduced the 10D and 30D amplifiers, which are specifically designed to drive permanent solutions. Offering a new price to performance ratio, the amplifiers are set to become keystones in the future of fixed pro audio installations, according to the company. They combine the predictable results and rider friendliness of d&b with features and costs tailored for installation applications.
Amnon Harman, CEO d&b audiotechnik (pictured), said: “For d&b, 2015 is the Year of Installation: we are delivering on our installation product promises, engaging even more closely with our customers and addressing the market on its own terms, particularly with our pricing.”
The 10D and 30D 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. 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 10s delay for each of the four channels. Between them they cover almost all install applications, differing only in output voltage and loudspeaker set-ups. The extensive DSP capabilities will be expanded further via future firmware updates.
The 10D amplifier is intended for small applications with lower SPL requirements, such as bars, lounges and conference facilities with flexible room configurations. It features set-ups for many d&b loudspeakers.
The 30D amplifier contains configurations for all d&b loudspeakers and is designed for medium to large applications with demanding SPL requirements, including medium-sized venues, stadiums, nightclubs, musical theatres, houses of worship and town halls.
To ensure seamless integration into existing permanent installations, the10D and 30D amplifiers offer five programmable GPI/O pins, meaning external devices can be used for control or detection functions. They provide both 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.
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 feedback we have received about the new installation amplifiers has been overwhelmingly positive,” said Harman. “That’s great news as we renew our focus on providing permanent d&b solutions, with a product portfolio that meets the integrator’s every need. With competitive cost to performance, the four-channel 10D and 30D amplifiers will benefit users wherever high-quality sound, reliability, usability and flexibility is expected.”
