The following illustrations will help you to properly connect your Hundred Duo Twelve to other amps, ex-
tension speaker cabinets, and recording and P.A. gear. Make sure the amp and all other gear are turned off
whenever you make or change any connections.
Using a heavy-gauge speaker cord, connect the output jack labeled Speaker 2 to the speaker input on an
extension cabinet with a 4- or 8-ohm impedance and power-handling capacity of at least 100 watts. A
16-ohm extension cabinet can also be used, but it will reduce the amp’s output. Don’t use a 2-ohm
extension speaker. Note: Make sure that the Speaker 1 output is connected to the Hundred Duo
Twelve’s internal speaker.
