Explanation of graphical symbols
The lightning symbol within a triangle is intended to alert
the user to the presence of uninsulated "dangerous
voltages" within the unit’s chassis that may be of
sufficient magnitude to constitute a risk of electric shock
to humans.
The exclamation point within a triangle is intended to
alert the user to the presence of important operating and
service instructions in the literature accompanying the
product.
Before using this product, carefully read the
applicable items of the following safety instructions.
1. Keep these instructions for future reference.
2. Read these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Keep water or other liquids away from the unit. Do not place
liquid filled containers, for example beverages, on top of the
unit.
6. Do not operate the unit while it is wet or standing in liquid.
7. Always operate the unit with the chassis ground wire
connected to the electrical safety earth. Do not defeat the
safety purpose of a grounding-type plug. A grounding-type
plug has two blades and a third grounding prong. The third
prong is provided for your safety. If the provided plug does
not fit into your outlet, consult an electrician for replacement of
the obsolete outlet.
8. Do not use this unit if the power cord is damaged or frayed.
Protect the power cord from being walked upon or pinched,
particularly at the plugs and the point where it exits from the
apparatus.
9. The unit is intended for use in a 19" rack. Follow the mounting
instructions. When a rack on wheels is used, exercise caution
when moving the loaded rack to avoid injury from tipping
over.
10. Unplug this apparatus during lightning storms or when unused
for long periods of time.
11. Never connect an output pin to any other amplifier input or
output pin or to the earth (ground). This may damage the unit
or lead to electric shock.
12. Lay all cables connected to the unit carefully so that they
cannot be crushed by vehicles or other equipment and that no
one can either step on them or trip over them.
13. Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way
such as:
– Power-supply cord or plug is damaged.
– Liquid has been spilled into the unit.
– An object has fallen into the unit.
– The unit has been exposed to rain or moisture.
– The unit does not operate normally.
– The unit was dropped or the chassis is damaged.
– Do not remove top or bottom covers. Removal of the covers
will expose hazardous voltages. There are no user
serviceable parts inside and removal may void the warranty.
14. Use the mains plug as the disconnecting device and keep it
readily accessible. If the mains plug is not readily accessible
due to mounting in a 19" rack, then the mains plug for the
entire rack must be readily accessible.
15. An experienced user must always supervise the equipment,
especially if inexperienced adults or minors are using the
equipment.

1.1. Intended use
The d&b D80 amplifier is designed for mobile applications and
intended to be used with all current d&b loudspeakers. A LINEAR
setup is available allowing the D80 to be used as a linear power
amplifier.
NOTICE!
The device complies with the electromagnetic compatibility
requirements of EN 55103 (product family standard for audio,
video, audio-visual and entertainment lighting control apparatus for
professional use) for the environments E1 (residential), E2 (business
and commercial), E3 (outdoor use in urban areas) and E4
(outdoor use in rural areas).
Acoustic interference and malfunctions may occur if the unit is
operated in the immediate vicinity of high-frequency transmitters
(e.g. wireless microphones, mobile phones, etc.). Damage to the
device is unlikely, but cannot be excluded.
1.2. D80 Concept
The D80 amplifier represents the next generation of high power
four channel Class D amplifiers. It is developed and manufactured
by d&b using Digital Signal Processing (DSP) to incorporate
loudspeaker specific configurations and user definable setups,
equalization and delay functions. The amplifier is designed to fully
drive all d&b loudspeakers and provide comprehensive
management and protection capabilities. This high performance
amplifier provides the power density required for both touring and
installation purposes while the powerful signal processing extends
the level of functionality of the on-board features.
The user interface of the amplifier consists of two elements: a color
TFT touch screen providing visual information and quick access to
the amplifier settings and a rotary encoder on the front panel for
data input purposes. To allow ease of operation when the amplifier
is below eye level, the front panel and the integrated display are
tilted upwards. As a result, the front panels of multiple amplifiers on
top of each other within a rack integrate to form one large control
surface.
The user definable equalizer features two independent 16-band
EQ groups within each channel. These provide parametric, notch,
shelving and asymmetric filters as well as a graphic EQ (via the
d&b R1 Remote control software V2) allowing instant switching
between two EQ curves for comparison. The delay capability
covers a range of up to 10 s. All loudspeaker specific functions
such as CUT, HFA, HFC, CSA or CPL are available. The DSP unit of
the amplifier has a fixed latency of 0.3 ms.

1. Introduction
d&b D80 Manual 1.8 en6
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 current 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.
