Connect INPUT/OUTPUT 1 on the JX-S555 to VCR 1 and
INPUT/OUTPUT 2 to VCR 2 to enable both to be used as
recording or playback decks in multi-dubbing.
The video/audio signals from VCR1 are output to VCR2 but
they are also output to VCR1 (because the OUTPUT
the JX-S555 is connected to the input of VCR1).
