2 Standard Setup/Wiring
SPEAKER
Socket for the connection of speaker cabinets. You
Stage or Recording Mixer
can connect any box or combination of boxes with
a total between 8Ω and 16Ω by means of a suitable
speaker cable.
The total impedance R of a combination of 2 cabs
with the impedances R1 and R2 can be determined
through the following formulas:
RED BOX
DI OUT
Serial Wiring: R = R1 + R2
Example: The use of two 8Ω boxes results in a total
Input
impedance of 16Ω.
However, cabs with serial connections are hardly
available today – parallel wiring is much more
common. The cab is either equipped with a parallel
output, or it features so called Y cables, distributing
the signal to 2 1/4" jack cables.
Parallel Wiring: R = (R1 x R2) / (R1 + R2)
Example, based on two 16 Ω boxes
R = (16 x 16) / (16 + 16)
R = 256 / 24
R = 8
IMPORTANT: With the Combo, this connection is
already used by the internal speaker. Of course, it is
possible to just pull the 1/4" jack connector out of the
SPEAKER socket and to connect a different guitar
cab instead.
MAINS IN
Mains socket for the included cable (MAINS
LEAD). Before starting the operation of your device,
please make sure that your local AC mains voltage
matches the voltage indicated on the device. Next to
the mains socket there is placed the bay containing
the main fuses.
Blown fuses must be replaced with identical ones (see
Specifications).
