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 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 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 utilizing 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. 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.
For further information regarding the integration of additional functions into the D80, please contact your Distributor.
Touring rack assembly
The D80 Touring rack assembly is designed as a fully equipped and prewired system rack, providing mains power distribution, connector interfaces and all internal cabling for three D80 amplifiers. It is equipped with a 32 A CEE mains power connector, a mains distribution device with a 32 A link, and a loudspeaker connector panel.
All internal audio and remote connections are fully prewired. A 1 RU drawer at the top stores the Rack link, providing two colour coded 2 x AES/XLR and one CAT5/etherCON® loom.
The 10 RU Touring rack houses a 19" internal shockmount steel frame accommodating three D80 amplifiers and the requisite connection panels. It comes with two sliding doors, a perspex window at the front, four wheels, six handles and recessed stacking moulds at the top.
The Touring rack assembly does not include the three D80 amplifiers.
