How much power does Iridium need to operate?

The current consumption on Iridium can vary quite a bit depending on whether or not the pedal is being used with headphones.  Iridium requires 9V DC center-negative power and between 300-500mA of current depending on usage:

• If you will not be using the headphone output on Iridium, we recommend providing at least 300mA of current.
• If you are using the headphone output on Iridium, we recommend providing at least 500mA of current as Iridium requires additional current to power the internal headphone amplifier.

NOTE:  The factory power supply that is included with Iridium provides enough power to cover both use cases above.
