1. POWER OUTPUT Jacks
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!
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)) or 15 watts (AC15C1). 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)/AC15C1 of a high quality, screened type.
These should not exceed 10 metres in length. Always use a non-screened Vox
approved speaker lead with the AC30C2(X)/AC15C1 Amplifier and extension
cabinets.
2. IMPEDANCE Select switch
16 OHMS:
Combos allow for the following configurations:
1) Set it to this if you use the internal speakers only.
2) Set it to this if you connect an external 16 Ohm speaker cabinet through the
External jack.
8 OHMS:
Combos allow for the following configurations:
1) Set it to this if you connect an extension cabinet through the Extension jack.
You’ll be running the internal and external speakers in parallel. The impedance of
the extension cabinet must be 16 Ohms.
2) Set it to this if you connect an external 8 ohm speaker cabinet through the
External jack.
