Dante™ Network Class D Professional Audio Amplifier
D-3000
SUMMARY
❖
OVERVIEW
❖
The D-3000 is a high power professional amplifier specially designed for the sound re-enforcement
market also referred to as SR, which incorporates a DSP, Digital Signal Processor and Audinates’s
Dante™ digital audio network. Dante delivers low latency, robust synchronization, I/O scalability, and
installation simplicity via standard IT technology. The superior efficiency of a Class-D amplifier means a
higher power output that is also more compact than an analog amplifier.

installation simplicity via standard IT technology. The D-3000 will deliver up to 3000 watts of power per
channel down to 2 ohm loads. Housed in two RU compact frameworks, the D-3000 Class D amplifier offers high power with reduced size and weight. The combination Class D topology amplification
circuitry combined with SMPS (Switch Mode Power Supplies) creates a high efficiency amplifier that offers reduced power consumption and low heat dissipation. The D-3000 is ideal for applications where
high power and efficiency is required. This may include House of warship, arenas, stadiums, concert
venues, touring or any other large-scale facilities.

DANTE Digital Network Audio Technology
Audinate’s Dante™ is a modern high performance digital media transport system that runs over standard IP networks.
Dante exceeds all other systems in speed, channel count, ease of use, flexibility, and scalability.
Dante offers a no hassle, self-configuring, true plug, and play digital audio networking experience. It is the solution for
transporting low latency uncompressed audio over standard IP ethernet networks with sample accurate synchronization,
automatic device and channel discovery, and easy to use signal routing.
Dante™ is built on IT standards, and is a complete media networking solution. Dante delivers a low-latency, tightly
synchronized, sample-accurate playback, which also simplifies installation and configuration of A/V networks. It is ideal
for applications where high power and large quantity of long-line speaker installation is required. As a result, Dante has
become the leading solution for a variety of professional applications as it demystifies audio networking.

DANTE Audio Network
Audinate’s Dante is an uncompressed, multi-channel digital media networking technology, with near-zero latency
(maximum delay time: under 1ms) and synchronization. Dante is currently the most advanced and most widely used
network audio technology. It transmits 48kHz, 24bit high quality digital audio in real time through standard TCP/IP
network protocol.
Brand Interoperability
Based on industry standards, Audinate’s Dante is an uncompressed, multi-channel digital media networking
technology, with near-zero latency and synchronization. Dante is the preferred audio networking solution that has been
adopted by more pro-audio AV manufacturers than any other networking technology. Interoperability is a reality today,
therefore, the Inter-M D-3000 series is compatible with hundreds of other Dante-enabled products available from the
world’s leading manufacturers. This enables consumers to mix devices from multiple manufacturers.
DSP Digital Signal Processing
The D-3000 series comes with a real-time digital signal processor and signal processing functions that include EQ,
dynamics, and delay. Most importantly, there is no need for separate external processors. Some of the available DSP
features include: 5 band Parametric, variable Q Equalizers (P-EQ), High Pass and Low Pass Filters, Limiter and Delay,
and Input and Gain Control. DSP and channel mapping functions for D-3000 series amplifier are configurable by an
HTML 5 web-browser interface.
Shelving EQ
Shelving filters are used to reduce or increase signals above or below a set frequency. Shelving filters are used as
common tone controls (bass and treble) found in most audio equipment. These implement a first order response and
provide an adjustable boost or cut to frequencies above or lower than a certain point.
P-EQ (PARAMETRIC EQ)
Parametric equalizers are multi-band variable equalizers, which allow the user to control the three primary parameters:
amplitude (GAIN), center frequency (Freq) and bandwidth (Q). The amplitude of each band can be controlled, the center
frequency can be shifted, and bandwidth (“Q”) can be widened or narrowed. Parametric equalizers are capable of
making much more precise adjustments to sound than other equalizers commonly used.
HPF (High Pass Filter)
A high-pass filter is a filter that passes higher frequencies well but attenuates lower frequency components. The adjustable range is from 20Hz ~ 20kHz, with a fixed slope of -18db/octave. High pass filters are useful for removing
unwanted signal below a set frequency.
LPF (Low Pass Filter)
A low-pass filter passes low-frequency components of signals while attenuating higher frequencies. The adjustable
range is from 20Hz ~ 20kHz, with a fixed slope of -18db/octave. Low pass filters are useful for removing unwanted
signal above a set frequency.
Limiter
A limiter allows signals below a specified input signal level (Threshold) to pass unaffected while attenuating the peaks
of stronger signals that exceed this threshold. The. Limiting is a form of dynamic range compression.
Delay
The delay circuit digitally records an input signal to an audio storage medium, and then plays it back after a period.
This is used to synchronise in time multiple speakers in a room with respect to a listening point such as to minimize
multipath reverberant sound. This technique distribute the sound evenly and ensure high quality sound for the entire
audience giving the listener the impression of a single sound source. The delay in the D-3000 can compensate for
distances of up to 17.0meters or 50ms.
