The d&b audiotechnik D80 is a 2U-high, four-channel power amplifier incorporating control and management capabilities for d&b loudspeaker systems.
The amplifier’s DSP supports configurations for the full d&b loudspeaker range. Each of its four channels feature a signal delay of up to 10s and two 16-band equalisers, providing parametric, notch, shelving and asymmetric filtering. Additionally, specific functions for d&b loudspeakers, such as Cut (Cut mode), CPL (Coupling), HFC (High Frequency Compensation) and CSA (Cardioid Sub Array) are included, as well as the selectable output configurations, Dual channel, Mix Top/Sub and 2-Way Active.
Both analogue and digital inputs and links are provided. All four outputs can deliver up to 4kW into 4Ω and are distributed through the single NL8 connector, or the individual loudspeaker outputs. The LoadMatch function electronically compensates for loudspeaker cable properties, without the need for an extra conductor. This results in increased accuracy of audio reproduction over a bandwidth of up to 20kHz, preserving the tonal balance when using cable lengths of up to 70m (230ft). The class-D amplifier uses a switch mode power supply with active Power Factor Correction (PFC) suitable for mains voltages 100-127V/208-240V, 50/60Hz. The output capability of the D80 is largely independent from voltage variations caused by substandard electrical sources; optimum system performance will be maintained when running from heavily loaded mains supplies.
All features and functions can be controlled via the TFT colour touchscreen and rotary encoder on the front of the amplifier. The D80 integrates with the d&b Remote network via the established Can-Bus or Ethernet, using the OCA (Open Control Architecture) protocols. The d&b R1 Remote control software provides a flexible workspace where all features, functions and controls available on the front panel of d&b amplifiers can be remotely grouped, monitored and managed. New versions of the d&b ArrayCalc simulation software, the planning tool for d&b systems, and the d&b R1 Remote control software, support the D80 amplifier.
‘The D80 is the result of careful planning and meticulous attention to detail during research, development and production,’ explains Product Manager, Marc Weber. ‘This included a period of thorough field testing over several years, at major festivals, tours, events and performances around the world. The feedback has instilled confidence that the D80 amplifier, which is now officially available, will fulfil the expectations of a d&b product well into the future.’
