Power requirements

oA quartz-locked digital synthesizer system with a
sophisticated Phase-Locked Loop (PLL) circuit allows
extremely precise tuning of FM, MW and LW stations
with an electronic digital readout on the frequency
display. A total of 10 stations can be preset.

oWith the single touch of a key, the desired function
can be initiated or a preset station can be immediately
tuned in and shown in the fluorescent display.
oAmplifier section provides 30W + 30W power output
(DIN 45500) for your home audio-video system.

oTwo separate speaker systems can be connected.
