When engineers at Audio-Hungary were trying to get the measurements for their amplifiers as perfect as possible, László Fábián (Executive Director) decided to train the ears of the engineers by exposing them to natural sound via live symphony concerts. That’s the kind of bold and different thinking that has led the company’s Qualiton brand of tube amplifiers and preamplifiers to quickly gain recognition in the European high-end audiophile market
Qualiton Audio's new
P200 Vacuum Tube Stereo Power Amplifier -
Qualiton Audio's new P200 Vacuum Tube Stereo Power Amplifier is at Musicraft (Derby)
The line-up of our
Classic Series amplifiers has been expanded with a new member, the Qualiton Audio
P200 power amplifier, which was presented to the public for the first time at the HIGH END Munich 2022 exhibition.
The
P200 is a versatile, high power amplifier, built on Tung-Sol KT120 (optionally KT150) beam tetrodes and our latest transformer designs. The
P200 features the latest version of our sophisticated Automatic Bias Control System for the four power tubes too. 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.
The amp has two distinct modes of operation, STEREO and BRIDGE mode. You can change the operating mode by reconfiguring the output connections, then use a STEREO INPUT /BRIDGE INPUT selector switch to select the input source for the chosen operation mode.
In STEREO mode the
P200 can be used as a conventional stereo power amplifier which has two unbalanced outputs for 4 or 8 Ohm speakers, with a maximum available output power of 2 x 100 W. In this mode you can connect an UNBALANCED or BALANCED stereo signal source to the amplifier.
In BRIDGE mode the
P200 can be used as a monoblock power amplifier with a BALANCED input. In this mode you can concentrate the total output power of the
P200 into a single channel: the two channels of
P200 are fed from a monaural, symmetrical audio signal (BRIDGE input), and a single 8 Ohm loudspeaker can be connected between the two amplifier outputs, bridging the output terminals. The maximum available bridged, monaural output power is 1 x 200 W.
