1.5 Rear Panel
IN Jack
This is the main input jack where your guitar plugs in.
SND 1-4, RTN 1-4 Jacks
These jacks provide mono-send mono-return effect loops. SND 1 4 send signals to effect pedals. RTN 1 4
receive signals from effect pedals. Connect the SND 1 4 jacks to the INPUT jack of each effect pedal, and
connect the OUTPUT jack of each effect pedal to the RTN 1 4 jacks.
SND 5, RTN 5S Jacks
These jacks provide a mono-send stereo-return effect loop. RTN 5S jack is stereo capable using TRS
connectors. If the last stage of the chain is the stereo-send effect loop or the output, the signal is output
in stereo. If the last effect loop in the chain is the mono-send effect loop, only the signal received at the
tip conductor of the RTN 5S jack is output.
SND 6S, RTN 6S Jacks
These jacks provide a stereo-send stereo-return effect loop. These jacks are stereo capable using TRS
connectors. If the last stage of the chain is the stereo-send effect loop or the output, the signal is output
in stereo. If the last effect loop in the chain is the mono-send effect loop, only the signal received at the
tip conductor of the RTN 6S jack is output.
SND VL, RTN VL Jacks
These jacks are for connecting a volume pedal. You can also use these jacks as send/return for a preamp.
OUT L, OUT R Jacks
These are the output jacks. OUT-L and OUT-R can be turned on/off independently. If the last stage of the
chain is the mono output, the OUT-L signal is split up in to the OUT-R.
TUNER Jack
This jack is for connecting an external tuner.
F1/F2 Jack
Latch or momentary function switch jack for amplifier channel switching or on/off controlling of reverb.
TRS plug's Tip : F1
TRS plug's Ring : F2
TRS plug's Sleeve : Common ground for F1/F2
ISO OUT Jack and ISO PHASE Switch
There is an isolation transformer before the ISO OUT jack. The isolation transformer may help reduce hum
that can occur when using two amps or 4CM. If the ISO OUT are used, ISO OUT can also be inverted the
ISO-OUT SOURCE
phase by pressing the ISO OUT PHASE switch. Refer to the
on the page 29 of the
manual.
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-LE without any changes.
DC12V Power Connector
This is the main power input for the EFX-LE. The EFX-LE requires a DC12V supply. The current draw is
approximately 250mA at DC12V (Center Negative).
