Signal Chain For Auditioning
Audition can be placed anywhere in your signal chain. The first thing you need to decide is which types of pedals you will audition the most. If you are going to audition a lot of overdrive pedals, put Audition closer to the beginning of your signal chain. If you are going to audition modulation, delays and reverbs, put Audition closer to the end of your signal chain. If you are unsure, put Audition after your last overdrive and before your modulation effects.

Signal Chain For Using An Amp FX Loop
If you are going to be using an amp’s FX loop, place

Audition after your last overdrive/dry effect and route signal to the ‘In’ jack on Audition. Now the ‘Send’ jack goes to the input of your amp, the ‘Return’ jack connects to FX send on your amp, the ‘Out’ jack goes to your modulation effects and the output of your last modulation effect goes to the FX return on your amp. If you don’t want to use the FX loop, simply unplug the send and return jacks and plug the last pedal on your board to the amp input.

In this configuration you can still audition pedals as normal.

Push Button
The push button is on Audition for musicians running Audition underneath their angled pedal board. Since a lot of angled pedal boards come with side panel jacks, you can now patch Audition into the side panel jacks and turn Audition ON to try a new pedal, or turn Audition OFF to bypass the side panel jacks and pass signal un-interrupted.

Power
The power jacks on Audition are used to power the LED and more importantly to the pedal being auditioned. Plug in 9-18v on the In/Out side of Audition and use the included DC cable to power the pedal you want to try.
NOTE: make sure that the power supply you use to power Audition has enough amperage (mA) to power the pedal you are wanting to audition.
