The Qualiton X200 is designed to serve analogue enthusiasts who need a combination of a high-performance vacuum tube power amplifier and a versatile preamplifier, along with sophisticated technical details, built into a single chassis. In this way, perfect matching is achieved - both sonically and technically - between the main signal processing sections.

The most important aspect of the design process was to meet the widest possible range of user needs in a compact footprint. All internal circuits were designed from scratch, avoiding the usual clichés throughout, to create a complete all-rounder. The X200 can be used as a separate preamplifier, as an integrated power amplifier, as a stand-alone power amplifier with direct inputs, or as a headphone amplifier, but other configurations are possible.

The low noise analogue front-end built around a wideband and transparent circuit and features a phono preamp with enhanced precision too. Line level and subwoofer outputs are absolute necessary in this category, these ports are included on the back. Audio Hungary have added a real specialty too: a built-in, studio grade Parallel Equalizer. This kind of tools is primarily used as a master channel effect in recording studios, to bring fresh air into the mix, as a finishing touch. Audio Hungary found that this effect can also be a huge help at home as well, as it can breath new life into certain, not so vivid records.

The balanced power amp is based on KT120 (optionally KT150) beam tetrodes and our latest, fully symmetrical output transformer design. Due to the symmetrical circuitry, we were able to further reduce the output noise of the output stage. In addition, our new BIAS section on the front panel makes it really easy to check and fine-tune the bias levels of the output tubes.

Audio Hungary’s popular X200 integrated amplifier has the latest version of our sophisticated Automatic Bias Control System introduced in the P200 earlier this year.

This circuit continuously monitors the behaviour of each tube and regulates the bias voltages accordingly, ensuring the smallest possible output voltage noise while guaranteeing the highest degree of linearity of the output stage. It also prevents the sensitive, high permeability transformer cores from saturating by precisely equalizing the quiescent currents of the power tubes. Finally, the bias system has a built-in soft-start function too, which prevents the tubes from drawing excessive current during start-up and eliminates pops and noises during power-up. The above means that no further adjustment is required once the electron tubes supplied with the unit have been installed, the circuit automatically takes care of everything.
