Broadcast FM/AM Tuner

While inheriting the sound quality and outlook of the former model S304 "nostalgia", it finished to a compact size. We thoroughly pursued high sensitivity and internal noise reduction, further improved the clear and high fidelity reception performance and fine stereophonic expression. In addition to the current-mode output, you can connect directly with the conventional voltage-mode amplifier with this single model.


Smart Size ― Easy to wiring from rear panel.

Incorporated all the functions necessary for reception of FM/AM into a compact dictionary size. Since the depth is narrow, it does not disturb the wiring routing from the rear panel. Because the power transformer is built in, you do not need an AC adapter to occupy the wall outlet.
