signal strength indicator on the multi-path reception display switchable
scan sensitivity switchable
Schotz noise reduction can be activated
Two switchable VHF antenna inputs
- The ST-70 (Japan Version) only has an antenna input. In addition, a switchable bandwidth switching wide / narrow (intermediate frequency filter)
- ST-7 (Australia) only one antenna input and a parallel 300 ohm connection
Remote control via preamplifier CA-7E is possible

Only one antenna input for the ST-70 (Japan version). For this, in addition, a switchable bandwidth switching wide/ narrow (intermediate frequency filter)
ST-7 (Australia) only one antenna input and a 300 ohm connection in parallel

The ST-7E allows you to use the great sound potential of even more FM stations within a stereo reception range that is about 8x larger as usual. This was achieved by installing the revolutionary SCHOTZ noise reduction. Many FM stations where you used to have to switch to mono are now listening in the highest sound quality.
