-3 band graphic equalizer (100 Hz/1 kHz/10 kHz)
-2 cassette decks
-4 speaker system ( woofer and tweeter)
-high speed dubbing and beat cancel
-AM/FM radio
-headphone and mic jacks

The M W717F is quite similar to the M W717L, except the M W717F does not have the CD/Line In jack or fine tuning knob.

.so the "L" version of this box actually has shortwave.Given the similarity in the two model,I have to wonder if it would be easy to retro-fit a line-in on your "F" version.
