Input (From Amp)
DI/Line Out (I.R.)
Connect 1/4” to DAW or mixer (FOH)
Plug in 1/4” speaker cable from 8 ohms
Speaker Out of amp (Generally 4 ohms is ok,
but consult your amp manufacturer)
Thru (To Speaker)
(optional)Connect to external speaker cabinet
Using this option disables the internal load. If a 1/4” cable is plugged in to this jack
MAKE SURE the other end is plugged in to a load or damage may occur
This signal is ltered through the impulse response,
meaning you will hear the tone with your selected I.R.
DI/Line Out (Un-ltered)
Connect 1/4” to DAW or mixer (FOH)
This is an unltered (dry) signal
with NO impulse responseaffecting the tone
USB
Connect to computer to manage impulse responses saved on device

2� Connect your amplier's 8Ω speaker out via 1/4" speaker cable to
Reactive Load I.R.'s INPUT – FROM AMP jack�
3� Connect the DI / LINE OUT – IR to record a signal that is affected by the
I.R. lter.
4� Adjust DI LEVEL (D�I� Section in detail, page 12)
5� Turn the IR SELECT knob to pick an I�R�
–Optional connections–
(dotted lines on diagram)
6� Connect the DI / LINE OUT – UN-FILTERED to record a signal that is

a speaker cabinet, connect the THRU – TO SPEAKERS jack using a 1/4"
(Speaker Cable)
(Optional)
(Speaker Cable)
(Optional)
speaker cable to a speaker cabinet�
!!
IMPORTANT NOTE: Using the THRU – TO SPEAKERS output
disconnects the internal load of the Reactive Load I�R� To optimize
performance and avoid damage, match the impedance of your amplier
to the connected speaker cabinet�
NEVER CONNECT THIS OUTPUT TO INSTRUMENT,
MIC OR LINE LEVEL INPUTS.
