The 2 RU four channel D80 amplifier is a high power density amplifier, ideally suited for use in both mobile and installation environments. It contains configurations for all d&b loudspeakers and a linear mode. The signal delay capability enables user definable settings of up to 10 s (= 3440 m/11286 ft) to be applied independently to each channel.
The same applies to the two 16-band equalisers, providing optional parametric, asymmetric, shelving or notch filtering.

The D80 incorporates a colour TFT touchscreen, offering quick access to the menu structure, while the rotary encoder can be used for fine adjustment. The front panel and the integrated touchscreen of the D80 amplifier is tilted up for ease of operation when the amplifier is below eye level. The equal ratio of signal input to amplifier output channels increases the application flexibility particularly for monitor, frontfill or effect channel use.

The LoadMatch function integrated within the D80 amplifier enables the electrical compensation of loudspeaker cable properties, without the need for an extra conductor. This results in an increased accuracy of audio reproduction over a bandwidth of up to 20 kHz, preserving the tonal balance when cable lengths of up to 70 m (230 ft) are used.

The D80 incorporates Class D amplifiers utilising a power supply with active Power Factor Correction (PFC) suitable for mains voltages 100 V/120 V/200 V/230 V, 50 – 60 Hz and maintains a stable output when used with weak or unstable mains supplies. The D80 amplifier outputs are NL4 connectors plus one entered NL8 connector with all pins driven. RJ 45 and etherCON connectors enable access to the d&b Remote network via CAN-Bus and OCA/AES70 via Ethernet respectively.
