Playback only; Auto-reverse, Dolby NR system, 16 Ω headphone jack, external power supply connection. StudioLine was a high-end line of audio portables from Grundig. The devices were high-priced and rounded the program upwards - StudioLine represented virtually the counterpart to FineArts Classic. These were so-called OEM products, which Grundig ordered from foreign manufacturers and offered in the period 1989-1993. Partially, the devices were available as identical counterparts from the actual manufacturer and were offered under the corresponding private brands. Mainly the devices were supplied by Matsushita (Panasonic, Technics) and Sanyo.
