!!CAUTION!

Hot! Risk of injury! During use, the valves will get very hot and high surface temperatures may be reached at the rear of this unit. To avoid burning yourself, make all connections while the unit is still cold.

ATTENTION! TO AVOID DAMAGE TO YOUR !!AMP, NEVER USE THE BUGERA VALVE AM-

PLIFIER WITHOUT A LOUDSPEAKER CON- NECTED!

The BUGERA amplifier has two paralleled LOUDSPEAKER outputs which are used to connect one or two speaker cabinets.

If you only connect one speaker cabinet, be sure that the

IMPEDANCE switch is set to match the impedance of theBUGERA head with a speaker cabinet connected cabinet.

If you want to connect two speaker cabinets, both cabinets should have to the same impedance. Be sure to have set the IMPEDANCE switch correctly. In this case, set it to half the value of one of the cabinets. When using two

16-Ohm cabinets, the switch therefore needs to be set to 8 Ohms; and with two 8-Ohm cabinets, set it to the minimum impedance of 4 Ohms.

CAUTION: The loudspeakers in the combos are connected in series. This results in an impedance of 16 Ohms.
