RC-1: FS-5U External FS Control Polarity Setting
If using an FS-5U connected to the RC-1 make sure to set the POLARITY switch direction toward the cable jack for proper FS functionality.
If set improperly (away from cable jack), upon pressing FS to STOP, the LOOPER will STOP but the LOOP will be ERASED!
The POLARITY will also be important when controlling the RC-1 from CTL/CONTROL OUTPUT of a BOSS EFFECTS SWITCHER like the ES-5, ES-8 and MS-3 or a MULTI EFFECT like the GT-1, GT-100, GT-1000, etc.
