The Critical Universal Receiver lets you connect a Critical wireless foot pedal to any power supply with a standard 1/4" foot pedal jack. It adds a maintained pedal mode and is compatible with all Critical wireless pedals.
It is powered by an external power adapter and comes with a 2 year warranty.
Press and hold the sync button on the receiver until the LED begins to blink. Press down on the Wireless Foot Pedal and the light indicator on the foot pedal and receiver will go solid and then go way to confirm that it is successfully synced.
The receiver offers a "Maintain Mode". By clicking the receiver once and when you step on the foot pedal it will maintain the power without having your foot on the pedal. To exit, click the receiver button again to switch back to "Manual Mode".
