Allowed the guitar notes to become forte

Laszlo Fabian

As far as the quality of our products is concerned, we do not make any compromises. Appliances launched under the brand name UNIVOX consist of electric circuits made of selected high-quality components. They are placed in solid and carefully conceived metal frames. We are working on developing durable power amps and integrated amps, designed for the Hungarian and international market, as well as in addition to vacuum tube amps on designing hybrid constructions using semiconductors.

Finally, we hope that our appliances, made to meet with high technical demands, will be to the liking of all the visitors of our products it is a preamp or a power amp, a hybrid amp or a full tube amp.

C200

To complete the line-up of our Classic Series, we designed a true all-rounder preamplifier, with beautifully balanced sound character, and one of the finest vintage tubes available, the Tungsram ECC83. The C200 uses 8 of them, so each output gets the flavour of these exceptional tubes.

As always, the most important aspect of the design process was to meet the widest possible range of user needs. Starting at the inputs, we have 4 UNBALANCED and 2 BALANCED line level inputs and a MM PHONO level input available. On the output side, the C200 is equipped with 2 UNBALANCED line level outputs (one of which can be connected to a subwoofer), we also have a BALANCED line level output and a HEADPHONE connection for dynamic headphones. With this set of I/O ports, users have plenty of options to connect the C200 into their system. And best of all, each output port carries the characteristics of classic Tungsram tube sound, while interference and noise levels have been reduced to the absolute minimum.

Along with the C200, we are also introducing an updated remote control, on which, in addition to the previous VOLUME UP, VOLUME DOWN and MUTE buttons, there is also a POWER ON/STANDBY button. After pressing this button, a circuit provides 1 minute of wake-up / warm-up time for the tubes. After this time, the C200's outputs will become active and ready for use.

P200

The line-up of our Classic Series amplifiers has been expanded with a new member, the Qualiton 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 behavior 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.

X200

Our popular X200 integrated amplifier just keeps getting better and better, as it now receives the latest version of our sophisticated Automatic Bias Control System introduced in the P200 earlier this year.

This circuit continuously monitors the behavior 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.
