Customers and reviews are all raves. -- True Audiophile
The APR 204 offers three unbalanced RCA line level 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 four audio sources, which one of the relay-switched, volume-controlled signal should reach the output RCA 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, realised exclusively with passive elements.
Audio Hungary uses double triodes ECC83/12AX7 both in the first and in the second voltage-amplifying stage . Through an appropriate tuning circuit and volume control potentiometer, the output of the PHONO stage is connected to the LINE stage, consisting of E88CC/6922 double triodes.
The APR 204 comes with an aluminum hand-held Remote that controls volume level and input selection.
Warranty: 2 Years. Tubes 6 Months.
