MDA series professional power amplifier as the tour equipment and it designed for large-scale concerts, tours, theaters, concert halls, nightclubs, DISCO and other professional venues, Not only have superior stability but also with the high-fidelity sound quality. The entire series use switching power supply and TD class circuit design with high efficiency, stable and reliable, and perfect sound quality.

MDA series amplifier to overcome the problems like: Power not strong for Class AB and Overheat of Class H. It has implements the proofread of class D amplifier and did not effects the sound quality. Also the MDA series amplifier solved the problems as : weight, dimensions, overheat of High-power amplifier. MDA series amplifier uses the smallest performance to output the large signal, which greatly improves the efficiency of power amplifier.

TD class means "Tracking Class D", That is, the power source tracks the audio signal at all frequencies. Although the final output stage is still of class AB, the principle of the class D power amplifier high-speed switch is added. The entire audio path remains under analog and the signal is not converted to digital pulses and filtered like a Class D amplifier not change into digital impulse the same as Class D amplifier. Class D technology can work well with all load, The output frequency response still have flat curve,output can be bridged and high reliability even when the load as low as 2 ohms.

The MDA series Amplifier earned a well-known reputation for many years!

  

Features:

1. Using Class-TD circuit topology and high-efficiency switch power designed for the power supply. With high-efficiency, power conversion, powerful output, low power consumption and environment protection.

2. 2. VPL technology allows the amplifier to work within the safe range of its hardware. It still can make sure with a well-controlled output even in the case of clipping. One amplifier can work under different occasions by VPL power management. For example: Use 1 or 2 output (isolated or bridge) to drive the bass cabinet. 1 or 2 output working for the main extend speaker, and then the Fourth output work to the distribution PA system.

3. VHF technology from the VHF detection circuit with intelligent resolute music signal and abnormal signal, Normal signals can full power through. When the dangerous VHF signals happen and the output will be muted, If the dangerous signals did not continuous, the output will automatically unmute. Meanwhile, the VHF error indicator at the front panel of amplifier turns on.

4. Perfect protection system: The entire device with a full-function protection which includes the power soft-start, current overload and short circuit, overheating, UHF, clipping limiter functions. Especially the no-relay output function, its fast response and accurate is much better than the relays.

5. Perfect designed cooling system: The amplifier can minimize the heat dissipation requirements while outputting high power. The radiator use a short duct of copper strip fin in order to make sure the output transistor keep in the same temperature. Also its thermal performance much better than aluminum radiator.

6. All input and output used in all Neutrik genuine original, The full range power output transistors from Onsemi, Improved the reliability of the devices for a long time demanding environments.
