QUALITON C 200
“ The C 200's impressive sonic shape shifting abilities elevates this preamplifier above the 'typical norm'. It is not easy to clearly stand out in the big audiophile products crowd, yet Audio Hungary pulled the rabbit out of the hat with this tube preamp. For its asking price, the C 200 offers a heck a lot of density and gain purity, and brought a big smile to my face. It always feels good when something is done properly, and in this case, is also priced more than properly"
Class A all tube Preamplifier with MM Phono Stage
The C 200 offers four unbalanced RCA line level inputs, two balanced XLR inputs, as well as one MM phono input. With the help of the audio source selector switch at the front panel, the user can determine, out of these seven audio sources, which one of the relay-switched, volume-controlled signal should reach the output RCA and XLR connectors.
If the input selector unit is in ‘P’, i.e. PHONO position, the signal to be processed gets on the grid of the first voltage-amplifying vacuum tube through RCA connectors marked PHONO - thus, through the shortest possible signal paths.
From here, in the before-mentioned classic way, the signal component gets on the grid of the second voltage-amplifying stage through a passive correction network between stages according to RIAA standard, realized exclusively with passive elements.
We use eight double triodes ECC83/12AX7 in total ... in the first and in the second voltage-amplifying stage, as well as in the phono stage. Through an appropriate tuning circuit and volume control potentiometer, the output of the PHONO stage is connected to the LINE stage.
The C 200 comes with an aluminum hand-held Remote that controls volume level and input selection.
