Rear Panel (Connecting Your Equipment)

To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.

A. INPUT (A/MONO, B) jacks
Connect your guitar, bass, or effect unit here.
Use the A and B jacks if connecting an effect unit that has stereo output. Use only the A jack if using this unit in mono.

The INPUT A jack also operates as the power switch.
The power turns on when you insert a plug into the INPUT A jack.

When powering up
Power-up equipment such as your guitar amp last.

When powering down
Power-down equipment such as your guitar amp first.

Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.

B. OUTPUT (A/MONO, B) jacks
Connect this jack to your amp or monitor speakers.
Use only the OUTPUT A jack if using this unit in mono.
Even sound that is input in stereo is output in mono.

Installing Batteries

Insert the batteries as shown below, being careful to orient the batteries correctly.

Batteries should always be installed or replaced before connecting any other devices. This way, you can prevent malfunction and damage.
If operating this unit on batteries, please use alkaline batteries.
Even if batteries are installed, the unit will turn off if you connect or disconnect the power cord from the AC outlet while the unit is turned on, or if you connect or disconnect the AC adaptor from the unit. When this occurs, unsaved data may be lost. You must turn off the power before you connect or disconnect the power cord or AC adaptor.
When turning the unit over, be careful so as to protect the buttons and knobs from damage. Also, handle the unit carefully; do not drop it.
If you handle batteries improperly, you risk explosion and fluid leakage.
Make sure that you carefully observe all of the items related to batteries that are listed in “USING THE UNIT SAFELY” and “IMPORTANT NOTES” (leaflet “USING THE UNIT SAFELY” and Owner’s manual).
“BATTERY LOW” will appear on the display if the batteries are low.
Replace them with new ones.
