1. POWER OUTPUT Jacks
COMBOS
This is where you can hook up an extension or external speaker cabinet(s) if
desired.
EXTENSION SP:
This speaker jack runs parallel with the internal speakers which
are wired for 16 Ohms. The extension cabinet must be 16 Ohms.
EXTERNAL SP:
This speaker jack will mute (disconnect) the internal speakers and
you can hook up either a 16 Ohm or 8 Ohm cabinet. Be sure to set the Output
Select switch accordingly.
NOTE!
Hooking up a cabinet through the External jack will mute (disconnect) the internal
speakers!
HEAD
LOUDSPEAKER:
The two LOUDSPEAKER Jacks are connected in parallel.
You can connect one or two 16 Ohm cabinets. You can only connect one 8 ohm
cabinet.
Be sure to set the IMPEDANCE SELECT switch accordingly.
WARNING!
To ensure that your system works correctly, you must observe the following
points.
a) Don’t use an extension cabinet whose impedance is other than 16 Ohms.
b) Don’t connect a speaker whose rated input capacity is less than 30 watts (for
AC30C2(X)/AC30CH) or 15 watts (AC15C2/AC15C1(X)/AC15CH). The speaker
may be destroyed if you ignore this caution—not recommended!
c) You must use a speaker cable to connect an external speaker. Don’t use a
shielded cable like the one you use to connect a guitar to an amp.
d) You must turn off the power before connecting the cable. Connecting the cable
while the power is turned on may damage your amp.
NOTE!
It is recommended that all audio cables, with the exception of the speaker lead,
used to connect to the AC30C2(X)/AC15C2/AC15C1(X)/AC30CH of a high qual-
ity, screened type.
These should not exceed 10 metres in length. Always use a non-screened
speaker lead with the AC30C2(X)/AC15C2/AC15C1(X)/AC15CH Amplifier and
extension cabinets.
