High quality and high performance are no longer in conflict! Digital dynamic drive and MOSFET linear drive make it possible. The l1000qx 4 channel end stage is located where high quality is required for high performance: for demanding noise makers and musicians. Through its flexible concept, it can be multi-functional, from monitoring pumps to adult PA.

Digital dynamic drive is a technology to improve the dynamic and efficiency of amplifier. A special processor and a high-speed buck converter produce very high efficiency in the range of more than 80%, that is, at the level of class D amplifiers. There is no fault caused by the switching process and the resulting distortion in the output signal.

MOSFET linear drive is a technology to improve sound quality under high performance dynamics. The l1000qx end stage uses power MOSFET and has the best SOA limit value. The MOSFET is driven linearly through a special circuit to approximate the "ideal MOSFET" and significantly reduce the adhesion coefficient, which is why the final stage has a clear, high resolution high fidelity sound.

The switching network part of PFC switch includes a two-stage energy storage unit with source power factor correction (PFC) and a full bridge converter with very high performance reserve. The switching network part is specially designed for audio amplifier. It does not produce any interference when the grid voltage is from 170V to 270V.

The audio processing l1000qx terminal has a digitally controlled audio processor, which is used to create different operating modes, thus providing a high degree of flexibility and versatility when using the end level. L1000qx has the following internal main functions: 4-channel, 2-channel, stereo 2-way, 3-way, 2-way bridge, combination and stereo (with mono subwoofer). The amplifier is controlled by three buttons on the front panel and can also be locked. The last stage is equipped with limiter and also supports protection circuit. The limiter has a flexible time constant, depending on the mode of operation and frequency range. The minimum time constant gives the limit in the channel, increasing the altitude from 900 Hz (the separation frequency of internal frequency cross). At the same time, the output power of these channels is as high as 300 watts, which is automatically limited to 8 ohm. If connected directly, the treble can be saved.

L1000qx has many protective circuits to prevent deformation and damage and ensure safe operation.
