No sound from switching modes as an pre-amplifier

When using the Pro iCAN/Pro iCAN Signature in pre-amplifier mode and go from Tube to Tube+ there is no sound but there are red LEDs flashing. In addition to this is started whilst in Tube+ mode it is find, the solid-state mode is fine too.

Answer: Red means the DC protection has engaged, possibly one tube is bad but the tube determines the DC operating condition. If they’re outside the “safe” zone the system will assert DC protection. There are four tube sections (2 channels X 2) and if one is “borderline” it could cause the behaviour (pre-amplifier mode from Tube to Tube+ doesn’t switch correctly).

If you seem to have these symptoms please open a support ticket.
