The device's signal delay feature allows users to customize settings for up to 10 seconds (equivalent to 3440 m or 11286 ft) for each channel. Similarly, the dual 16-band equalizers come with selectable parametric, asymmetric, shelving, or notch filters.
The D80 boasts a vibrant TFT touchscreen that ensures quick menu navigation. Additionally, its rotary encoder aids in precise adjustments. The D80's front panel and touchscreen are thoughtfully slanted, enhancing usability when placed below the user's line of sight.
Its balanced ratio of input to output channels augments its versatility, especially beneficial for monitors, front fills, or special audio effects.
The D80's built-in LoadMatch function compensates for the properties of loudspeaker cables, eliminating the necessity for an extra conductor. Consequently, this promises an accurate sound reproduction across a spectrum up to 20 kHz and retains the audio's tonal consistency for cable lengths up to 70 m (230 ft).
The D80 employs Class D amplifiers powered by a supply with proactive Power Factor Correction (PFC). This makes it compatible with 100 V/120 V/200 V/230 V mains voltages at 50 - 60 Hz and ensures consistent output even with fluctuating power sources.
It comes with an NL8 connector that combines all outputs. Additionally, users can opt for either the NL4 or EP5 output models. For streamlined control, the device provides RJ45 and etherCON connectors, granting access to the d&b Remote network via CAN-Bus and OCA/AES70 through Ethernet, respectively.
