Overview

As the name suggests, Reactive Load I�R� adds impulse response technology to the original Reactive Load, allowing you to quickly and
easily access an array of expertly mic’d speaker cabinets. It comes
preloaded with 16 Suhr speaker cabinet impulse responses captured by Celestion� Reactive Load I�R� is an open system, so you can load 3rd party impulse responses via the USB port�

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 unltered (dry) signal
with NO impulse response affecting the tone
USB
Connect to computer to manage impulse responses saved on device

How to connect to a DAW (Digital Audio Workstation)

This guide will show the ways you can connect your Reactive Load I�R� to a digital audio workstation�
Steps:
1� Plug in the provided 9Vdc power adapter�
2� Connect your amplier'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
NOT affected by the I.R. lter, meaning it is just your amp’s tone (with no
speaker ltration), for later processing in your DAW. If you'd still like to run
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 amplier
to the connected speaker cabinet�
NEVER CONNECT THIS OUTPUT TO INSTRUMENT, MIC OR LINE LEVEL INPUTS.
