If you are using one speaker cabinet, you can plug into either speaker jack. Make sure your impedance selector is set to the same impedance as the speaker cabinet.

You should always return the amp to standby before turning off to allow the amp to “discharge” voltage. Doing this habitually will extend the life of your amp. SPITFIRE II OWNER’S MANUAL PAGE 5 OF 17... -
Page 9: Half Power
HALF POWER Your Spitfire II also comes equipped with a Half Power switch, which switches your output stage to triode rather than pentode operation. This cuts your 100w amp to effectively half- power allowing you to open it up without the ear splitting 100watts of power! It is preferable that you operate this switch only when the amp is off, but failing to do so will not likely damage your amp. -

Two rhythms and a boost for lead? You got it. One rhythm and one lead, forget the boost? All within your control on this amp.

“insert” cable (available at most music stores and generally used in PA’s), which is TRS at one end (connect this to the amp) and “Y’s” out to two mono jacks at the other end (connect to your switching device). SPITFIRE II OWNER’S MANUAL PAGE 13 OF 17... -

It is still good, however, to verify bias. If you feel competent to check or adjust bias, call DA for instruction. But generally, bias should average between 33 and 39 milliamps SPITFIRE II OWNER’S MANUAL PAGE 14 OF 17... -
