Skip to contentIridium has a single input that will work with MONO or STEREO TRS input signals depending on the setting of the Input Selector switch on the back of the pedal. The input impedance is 1 Meg Ohm.
Iridium can accept Instrument (-10dB) or Line Level (+4dB) signals up to +8dBu. If using Line Level signals, please make sure to set the INPUT LEVEL to LINE.
***NOTE: Never connect the speaker output from an amplifier into Iridium!!!***
Iridium is an amp modeler and IR cab processor that can be used in a variety of ways. With both the amp and IR cab processing active, it is designed for:
It is not really recommended to be placed in front of an amplifier, but if you disable the IR Cab in Cab Bypass mode, you can connect Iridium’s output(s) into the Power Amp Input/Effects Return of an amplifier to use as the preamp for your amplifier.
Iridium’s LEFT and RIGHT audio outputs are 1/4″ unbalanced buffered outputs. The buffered signal when both engaged or bypassed can handle sending signals over long cable runs. However, in some setups, using a DI may help if you encounter any noise or ground loops when connecting Iridium’s outputs directly to a PA/mixer or require balanced connections.
Iridium gives you the option to bypass either the amp modeling or the IR cab processing for different use cases. The ROOM processing is always active in any of these output modes.
To bypass either the amp or IR cabinet:
