d&b D80 - Manual (Page 6)

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.
