Always set the impedance switch to match
the cabinet impedance. Here is some handy
information.
To determine the proper setting using mul-
tiple cabinets of the same impedance,
simply take the impedance of one cab divided
by the number of cabinets. For example, if you
have two 16 ohm cabs, simply divide 16 by 2
for a total load of 8 ohms.
The MAIN (USE FIRST) and the EX-
TENSION speaker outputs are in parallel.
This means if you connect one cabinet to each
speaker jack on the amp, you will use the ex-
ample above to calculate the proper setting for
the impedance switch.
For example, if you connect one 16 ohm
cabinet to each output, the load the amp see is
8 ohms … 16 ohms divided by two equals 8
ohms.
