Harmony G-XT: Sound is distorted when the pedal is connected to a Bose L1 MK11

Question

When I connect the Harmony G-XT to my Bose L1 MK11 I get a loud distorted, whirling sound from the speakers. What is wrong?

Answer

This happens because the ToneMatch feature in the Bose L1 MK11 is turned on. If you turn this off the problem should disappear.
