The D80 amplifier


More refined than anything before, the new four channel D80 amplifier sits right at the very heart of any d&b audiotechnik system.

The high power density 2 RU D80 amplifier incorporates configurations for the entire d&b loudspeaker range. Each of the four channels feature a signal delay of up to ten seconds and two 16-band equalizers, providing parametric, notch, shelving and asymmetric filters. Additionally, specific functions for d&b loudspeakers are included as well as selectable output configurations. Both analog and digital inputs and links are provided. All four outputs can deliver up to 4000 Watts.

The LoadMatch function electronically compensates for loudspeaker cable properties. This results in increased accuracy of audio reproduction over a bandwidth of up to 20 kHz, preserving the tonal balance. The Class D amplifier utilizes a switch mode power supply with active Power Factor Correction (PFC). The output capability of the D80 is largely independent from voltage variations; optimum system performance will be maintained when running from heavily loaded mains supplies.

All features and functions can be easily 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. 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.
