When connecting a tube amp to the WAZA Tube Amp Expander, set the INPUT LEVEL switch to match your amp’s output wattage.
- For a 150-watt amp: set the switch to 100 W.
- For amps 100 W or less: use the lowest setting where the INPUT SIG/PEAK indicator does not turn red while playing. (For example, if the indicator stays off at both 10 W and 50 W, choose 10 W.)
