Startup
Connecting the Power Cable:
Make sure the power switch (see page 7) 10is set to OFF before you connect the power cable at the X4 V.
Plug the power cable into a grounded outlet only.
The X4 V runs on AC power: 100, 120, 230, or 240 volts at 50–60 Hz.
Audio Connections
Make sure your sound system is at a safe volume level. Also make sure that the X3’s
VOLUME knob (on the far left side of the front panel) is all the way down.
Plug in a pair of stereo headphones or run two standard 1/4‐inch instrument cables from the
MAIN outputs of the X4 V to your amplifier or mixer for stereo included Rotary Sim Vent II.
11-Pin Rotary Output:
The X4 V is designed to connect with a 11-pin rotary speaker cabinet. When a physical rotary speaker is
connected via the 11-pin plug, the [RUN] and [SLOW/FAST] control buttons perform the same functions as with
the internal rotary simulation. The rotary speed can also be controlled with a foot switch like e.g. a BOSS FS-5L
(latch mode switch with stereo TS ¼ inch plug only! See page 6).
Volume/Expression-Pedal Input
Connect an expression Pedal like the Yamaha FC7 or similar (10k to 47k) here to control organ volume while
you are playing (see page 6).
Foot Switch Input - Slow/Fast Vent II
(Slow/Fast Vent Jack)
Note: Momentary Foot-Switch !! e.g. BOSS FS-5U!!
The contact must be open and close only briefly when the button is pressed, then immediately opens again
when you let go (see Page 6)
