The MD44 Series is designed for use at festivals, tours, clubs and all Live/Touring events.
Designed for use at festivals, concert tours, clubs, and all live/touring events, the MD4420 delivers a unique combination of massive, sustained power and advanced DSP processing, representing a significant leap forward in audio technology.
It shares the same features and size as the eight-channel MD4820 , but can deliver 5,000 watts to each of its four channels (up to 10,000 watts per pair in bridged mode). We're not talking about transient, peak, or burst power, but pure RMS power delivered by all channels simultaneously, under parallel loads, even with the densest audio material. With our amplifiers, you don't have to worry about channel power distribution or power sharing. This has been repeatedly confirmed in dozens of installations and live situations worldwide, as well as independent tests (e.g., www.Production-Partner.de).
You can use all the power you paid for, all the time.
How does it work? Our devices achieve this because our 5th generation Class D amplifiers have been redesigned for maximum efficiency, eliminating unnecessary loss- and noise-generating components. The topology and physical layout of the components enable 7% to 10% higher efficiency than competing products. This efficiency translates directly into higher power output over time, without generating heat, which is crucial. This approach, in addition to stable operation in the harshest conditions, also results in pristine sound and a noise ratio of 113 dBA from analog input to amplifier output—an achievement without peer (or at least, we don't know of any such examples).
Each channel can deliver maximum power under 2, 4 and 8 ohm loads, but also on 25V, 75V and 100V DC lines. This solution allows designers a high degree of flexibility in installations.
You don't need to use external software and file exports.
The 96kHz DSP integrated into the amplifier is essentially a series of Sharc and ARM chips programmed entirely by the Linea Research team. This resulted in the development of unique, unmatched LIR (Linear Phase IIR) crossovers. These are as easy to use as those you're used to, yet don't affect phase and have a lower inherent delay than complex FIR filters. There's no need to use external software or export files. Set up the crossover and you can instantly verify the filter's performance without group delay! The VX limiting algorithms are also unique, allowing for different limiting in different frequency ranges within a single channel, as well as RMS, Peak, and overexcursion limiters.
Convenient, transparent operation.
For communication, we use Ethernet ports, which are independent of the Dante inputs and outputs, and the System Engineer application on a PC (Mac users must use VMWare or Parallels). The front panel displays all key information, such as system stability and audio levels, but it lacks switches to prevent unskilled operators from making mistakes. The device's memory can store a range of settings and so-called "snapshot" scenes, familiar from modern mixing consoles. Snapshots can be changed via an analog output and a simple contact switch, making this task suitable for anyone, even the most inexperienced.
Dedicated, intuitive System Engineer software.
Working with System Engineer is intuitive, and the interface is graphically clear. The application offers many convenient and time-saving features for managing presets, layering mutes, gains, delays, and, of course, EQ across the entire system (not just within a single amplifier). Control via third-party devices is also possible via TCP/IP, RS232, and RS485 protocols.
