The amplifier enables up to four input channels, which may be four

analog inputs, two analog and two AES channels or four AES

channels. Each input channel can be routed to any of the output

channels A to D. XLR connectors 2 and 4 of the D80 can be used

as either digital or analog inputs, connectors 1 and 3 are analog

inputs. Link outputs are supplied for all inputs. This 1:1 ratio of

inputs to amplifier output channels increases flexibility of

application, particularly for use as monitor, frontfill or effect

channels.

The D80 amplifier outputs are optionally NL4 or EP5 connectors

plus one centered NL8 connector with all pins driven. The latter

serves as an interface to a rack panel or to loudspeaker multicores

and breakout adapters. To simplify configuration, the output mode

of the amplifier can be configured like a set of two dual channel

amplifiers providing Dual Channel, Mix TOP/SUB or 2-Way Active

modes for the left and the right channels A/B and C/D,

respectively.

For applicable loudspeakers, d&b LoadMatch enables the D80

amplifier to electrically compensate for the properties of the cable

used to connect the loudspeakers to the amplifier output. This

function which covers a bandwidth of up to 20 kHz preserves the

tonal balance when cable lengths of up to 70 m (230 ft) are used.

Due to its design LoadMatch does not require additional wires and

is therefore applicable with any connector type used.

To provide optimum compensation, cable length and cross-

sectional data as well as the number of loudspeakers connected to

the amplifier channel can be entered on the amplifier.

The D80 utilizes a switch mode power supply with active Power

Factor Correction (PFC) to produce a clean current draw and

ensure stable and efficient performance under adverse mains

conditions. The high power capabilities provide increased power

to fully drive all applicable d&b loudspeaker cabinets and

sufficient headroom for any future systems.

Remote control and full system integration are realized using the

d&b ArrayCalc simulation software and R1 Remote control

software V2. The D80 amplifier includes two Ethernet ports on

etherCON connectors to enable daisy chaining. Both Ethernet and

dbCAN protocols are incorporated. The Ethernet protocol

implemented in the d&b R1 Remote control software V2 and the

D80 amplifier is a protocol developed by the OCA Alliance (Open

Control Architecture Alliance), of which d&b is a founding member.
