STACKING SETUP (GC-405X)
* This unit is equipped with a protection circuit. A brief inter-
val (a few seconds) after power up is required before the
unit will operate normally.
* Always make sure to have the volume level turned down
before switching on power. Even with the volume all the
way down, you may still hear some sound when the power
is switched on, but this is normal, and does not indicate a
malfunction.
11. Headphone Jack
Connect headphones to this jack. When headphones are con-
nected, no sound will be output through the internal speakers.
12. External Speaker Jacks
Connect external speakers to these jacks.
You can connect the Speaker Box to the GC-405X through
these jacks. (Refer to the figure for “STACKING SETUP.”)
Sound will be output from the internal speakers even when
external speakers are connected (parallel connection).
* When you connect speakers other than the supplied Speaker
Box, be sure to use ones that are over 8 ohms.
13. Effect Return/Main In Jack
Connect this to the output jack on the external effect unit. This
can also be used as a main-in jack.

Connect from here to the input jack on an external effect unit.
This can also be used as a pre-out jack.
