D80 Amplifier
The two (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 user-defined audio-signal delay capabilities enable up to ten (10) seconds (equivalent to 440m/11286ft) to be applied independently to each channel. The same applies to the two (2) 16-band equalizers, 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 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 20kHz, preserving the tonal balance when cable lengths of up to 70m (230ft) are used.

The equal ratio of signal input to amplifier output channels in the D80 increases application flexibility particularly for monitor, frontfill or effect channel use.
The D80 incorporates Class D amplifiers utilizing a power supply with active Power Factor Correction (PFC) suitable for mains voltages 100V, 120V, 200V, 230V, 50Hz - 60Hz and maintains a stable output when used with weak or unstable mains supplies.
An NL8 provides all outputs on a single connector, while individual outputs are optionally NL4 or EP5 connectors. RJ 45 and etherCON connectors enable access to the d&b Remote network via CAN-Bus and OCA via Ethernet respectively.
