INPUT/OUTPUT JACK PANEL
IN Terminal
Input terminal for each loop. Connect your guitar, etc. to
this jack.
SEND (N.C) Terminal
Send terminal of effect loop. Used to send signals to an
effects unit, amplifier, etc. The signal fed to the IN terminal
appears here when this loop is turned on and the signal is
muted when this loop is turned off.
This terminal can be used as a control terminal (normally
closed) to switch amplifier channels, etc. The tip and ground
in the jack are connected when the loop is turned off.
RETURN Terminal
Return terminal of effect loop. Used to receive signals
from an effects unit, guitar, etc.
OUT (N.O) Terminal
Output terminal to supply the signal after passing through
the effect loop. The signal fed to the RETURN terminal
is output from this terminal when the loop is turned on.
The signal fed to the IN terminal is output when the loop
is turned off.
This terminal can be used as control terminal (normally
open) to switch amplifier channels, etc. The tip and ground
in the jack are connected when the loop is turned on.
C1/C2 Terminal
Connect a latch type switch to this terminal to control
turning on/off of the respective loop. Since it is a stereo
phone jack, LOOP1 is turned on when the tip is connected
to the ground and LOOP2 is turned on when the ring is
connected to the ground.
NOTE: Inserting a standard mono plug in this terminal
automatically turns on the LOOP2 terminal but this will
cause no problem in actual usage. On/off control of the
LOOP2 becomes available by inserting a plug in the
LOOP2 control terminal (C2).
C2 Terminal
Connect a latch type switch to this terminal to control
turning on/off of the loop. Since this is a mono phone
jack, LOOP2 is turned on when the tip is connected to
the ground.
ON/RMT Selection Switch
When this switch is set to the RMT side, the switch
connected to the control terminal can be used to turn on/
off the respective loop.
When this switch is set to the ON side, the respective loop
is forcibly turned on irrespective of the status of the switch
connected to the control terminal.
POWER DC 9V IN Terminal
Power Indicator
This LED illuminates when the LB-2 is properly powered.
 Loop On Indicator
This LED illuminates when the corresponding loop is
turned on.

Main Features of LB-2
Any AC adapter that has regulated 9V DC output, center
negative polarity, and more than 75mA power supply
capability can be used. A standard 5.5 x φ2.1mm plug
is acceptable.

HOW TO USE LOOPS
2-1 As Effect Loop
Feed signals to the IN terminal and connect from the SEND
terminal to effects unit’s input.
Connect from the effects unit’s output to the RETURN
terminal, then from the OUT terminal to a device that is
placed downstream.

2-2 As Output Selector
The LB-2 can be use as an output selector to choose one
of two outputs.
Feed signals to the IN terminal and connect from the SEND
terminal to the input of an amplifier, etc. The RETURN
terminal should be left unplugged. Connect from the OUT
terminal to the input of another amplifier, etc.
When the loop is turned on and the output 1 is selected, the
output 2 is muted to prevent crosstalk or noise. Conversely,
by turning off the loop and selecting the output 2, the output
1 is muted.
2-3 As Input Selector
The LB-2 can be used as an input selector to choose one
of two inputs.
Input 2 signal fed to the RETURN terminal is supplied from
the OUT terminal when the loop is turned on. By turning
off the loop, input 1 signal fed to the IN terminal is supplied
from the OUT terminal. The SEND terminal should be left
unplugged.
2-4 As Amplifier’s Send/Return Effect Loop
Connect from an amplifier’s send to the LB-2’s IN terminal
and then from the LB-2’s SEND terminal to an effects unit’s
input.
Connect from the effects unit’s output to the LB-2’s
RETURN terminal and from the LB-2’s OUT terminal to the
amplifier’s return input.
Since the grounds of LOOP1 and LOOP2 are isolated,
LOOP1 can be used as an effect loop between your guitar
and amplifier, and LOOP2 as an amplifier’s send/return
effect loop.
2-5 As Stereo Effect Loop
The LB-2 can be used as a single loop box for a device
supporting stereo operation, assuming LOOP1 is for Left
channel and LOOP2 for Right channel. Note that the IN/
OUT terminal of each loop does not support a standard TRS
plug, you need to use a standard mono plug.
2-6 As Mute Box
The LB-2 can be used as a mute box that cut the signal fed
to the IN terminal from the OUT terminal. The output from
the OUT terminal is muted when the loop is turned on. The
SEND and RETURN terminals should be left unplugged.
