Le R30 n'a qu'une sortie HP, semble-t-il.
Donc tu ne peux utiliser qu'une baffle à la fois.
Je cite le manuel:
:"Speaker output R30-112
A speaker must always be connected to your Thirty Twelve, whether it's the internal 12" speaker or an extension speaker cabinet. The amp is designed to deliver at least 30 watts to an 8-ohm speaker load. If it has to drive speaker loads lower than 4 ohms, its output transformer or other components could be damaged. You can use an 8- or 16-ohm extension cabinet, with the internal speaker unplugged). Never use a 2-ohm speaker cabinet. The only time you may run the amp without a speaker connected is if you have a proper "dummy" impedance load box plugged into the speaker output. Using a dummy load protects the output transformer, but prolonged use shortens the life of the amp's output tubes. If you use your Thirty Twelve to drive an extension cabinet, use a heavy-gauge speaker cord. A shielded guitar cord can't handle the power that your amp provides, and therefore won't sound right--plus it may actually harm your amp. Refer to the connection diagrams for more information.
