BUF IN Jack
This is the buffered input jack where your guitar plugs in.
IN Jack
This is the passive input jack where your guitar plugs in. Use this jack if you do not use the EFX-ME’s input buffer.
SND 1-5, RTN 1-5 Jacks
These jacks provide mono-send mono-return effect loops. SND 1-5send signals to effect pedals. RTN 1-5receive
signals from effect pedals. Connect the SND 1-5jacks to the INPUT jack of each effect pedal, and connect the
OUTPUT jack of each effect pedal to the RTN 1-5jacks.
OUT Jack
This is the passive output jack. This jack is directly connected to the output of loop 5, with no circuitry in between.
BUF OUT Jack
This is the buffered output jack. There is the CLICK-LESS circuitry between the output of loop 5 and this jack.
TUNER Jack
This jack is for connecting an external tuner.
F1/F2 Jack

MIDI IN, MIDI OUT/THRU Connector
MIDI IN connector receives MIDI signals from an external MIDI device. MIDI OUT/THRU connector is used to feed
MIDI signals to external MIDI devices. When the operation mode of MIDI OUT/THRU has been set to 'THRU', MIDI
signals received at MIDI IN pass through the EFX-ME without any changes.
DC9V Power Connector
This is the main power input for the EFX-ME. The EFX-ME requires a DC9V supply. The current draw is
approximately 200mA at DC9V (Center Negative).
