STEREO SIMUL-CLASS 2:90 Operating Manual 1.
Congratulations. You have just become the owner of the most "Tone Full" three and one half inches of rack guitar power available today. Don't let it’s mere two spaces fool you - This amp has a BIG voice and was bred to be a serious contender in any arena.
FRONT PANEL One look at the 2:90's front panel probably told you "easy to use" ... right? We think so... but after a closer look, you notice three small LED's labeled - "Deep, 1/2 Drive, and Modern." Since the rest of the Front Panel is virtually self explanatory.
1/2 DRIVE Like Deep, this LED indicates the 1/2 Drive mode has been selected. Again - connect the TriAxis switch jack to the 1/2 Drive jack on the rear left of the 290.
LEVEL A/B These two pots control the volume level of each side or channel of the 2:90. Since there's only one Standby Switch on this unit they may also be useful as channel muting controls. NOTE: If only one speaker is to be used on one channel and no speaker load on the other, always turn the unused channel’s Level Control to zero.
BACK PANEL Now that we've mastered the Front Panel and found its simple layout easily digested let's move aft for some jacks and tubes. Let's take the connections first and start with the jack panel. INPUTS B/A : Here in the upper left corner of the jack panel you'll find two 1/4” insulated jacks.
