Inter-M Announce the New D-3000 Power Amplifier

High-Power Professional Amplifier

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 synchronisation, I/O scalability, and 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 synchronisation, 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 synchronised, 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 protocol.

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 Equalisers (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.

Parametric equalisers are multi-band variable equalisers, which allow the user to control the three primary parameters: amplitude (GAIN), centre frequency (Freq) and bandwidth (Q). The amplitude of each band can be controlled, the centre frequency can be shifted, and bandwidth (“Q”) can be widened or narrowed. Parametric equalisers are capable of making much more precise adjustments to sound than other equalisers 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.

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.

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 minimise 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.

The amplifier input level or volume control can is remotely controlled or pre-set via the web-browser control panel. This feature can be bypassed for full volume or muted.

Input Mapping
The mapping control allows the matrixing of 8 digital inputs with the 2 local analogue inputs

Web-Browser Control Panel
The Web-Browser control panel is a web-based interface (control panel) that is used to interact directly with the Amplifier for making configuration changes and for requesting information from the player.

The Web-Browser control panel runs directly on port 80 of the amplifiers internal web server and can be accessed from any browser including web-enabled devices like tablets and smart phones.

Class D audio amplifiers offer greater power efficiency over traditional amplifiers. Among their advantages includes their reduced physical size and lower heat dissipation. They offer less than 1% THD (Total Harmonic Distortion), with an increased signal to noise ratio to 90db, and a widened frequency response from 30Hz ~ 20 KHz. Class D audio amplifiers offer greater than 90% power efficiency over traditional amplifiers and SMPS provides high efficiency and low weight. The DPA series is fully equipped with a protection circuit against short circuit, overload, power, and DC output.

Same Powerful Output from a More Compact Amplifier
The superior efficiency of a Class-D amplifier means higher power output that is also more compact than an analogue amplifier. Only 2 rack units in size, the DPA Class D audio amplifier with ECO Digital design offers greater than 90% power efficiency and lower heat dissipation over traditional analogue amplifiers with lower efficiency and greater noise.

LED Display
Amplifier status monitoring is easy with a LED display (Power on, Standby, Signal/-30dB, -10dB, Clip, fault, AC, DC).
