Rear Panel
L. POWER— Turns the amp ON-OFF. You can extend the
life of the amplifier tubes by keeping the STANDBY {M}
switch down for the first 60 seconds that the power
is ON.
M. STANDBY — In standby, the amplifier outputs are dis-
abled while power is supplied to the tube filaments
only, keeping them warm. *Tip: Use STANDBY instead of
switching the power off during short breaks to extend
tube life and avoid the warm-up delay upon returning to
play.
N. IEC POWER INPUT SOCKET— Connect to a grounded
outlet using the supplied power cord, in accordance with
the voltage and frequency specified on the rear panel of
your amplifier.
O. FUSE— Protects the amplifier from electrical faults. Only
replace a blown fuse with the type and rating specified
on the rear panel of your amplifier.
P. SEND LEVEL— Adjusts the output level of the SEND {Q}
jack. Use to accommodate the input sensitivity of your
external effects device.
Q. SEND / RETURN— Effects loop jacks. Connect SEND to
your effects device input and RETURN to the effects out-
put. TIP: The FX button on the footswitch can function as
a volume boost switch even without effects in the loop.
Simply connect SEND to RETURN with a guitar cable then
adjust SEND LEVEL {P} and RETURN LEVEL {R} for the
desired level of volume boost.
R. RETURN LEVEL— Adjusts the RETURN {Q} jack input
level going into the power amp. Use to match the vol-
ume level of the amp when effects are off, or to set an
alternate volume level selectable from the footswitch.
S. PRE AMP OUT — An unbalanced, line-level output
(includes Reverb on the 112 Combo amps) suitable for
connection to recording equipment and sound systems.
NOTE: You can connect this jack to the POWER AMP IN
jack on a second Super-Sonic amp for a double amplifier
setup. in which you can control both units from the con-
trol panel of the primary amplifier.
T. POWER AMP IN — A direct input to the power amplifier.
The preamp circuit is automatically disconnected when
a plug is inserted into this jack. Useful when adding a
second Super-Sonic as an extension power amplifier.
Connect this jack to PRE AMP OUT from another amp.
U. FOOTSWITCH— Connect the included 3-button
footswitch to enable remote selection of: Amp Voicing {C},
Channel {E} and FX Loop Bypass. These buttons {C & E} are
disabled on the front panel when the footswitch is con-
nected.
V. MAIN SPEAKER / EXTENSION SPEAKER—
����������������������� A speaker must ALWAYS be plugged into the MAIN
SPKR jack when the Super–Sonic amplifier is ON or
damage may occur. Switch the amplifier OFF or to
STANDBY while changing speaker connections or imped-
ance settings.
• (112 COMBO AMPS) — Keep the internal speaker con-
nected to the MAIN SPKR jack for normal operation. Plug
an 8Ω extension speaker into the EXT SPKR jack and the
Super–Sonic amplifier will automatically switch to handle
a 4Ω load.
MAIN EXT IMPEDANCE

8Ω + None = 8Ω
8Ω + 8Ω = 4Ω
• (HEAD AMPS) — Connect speaker enclosures and set the
IMPEDANCE SELECTOR {W} according to the table below.
MAIN EXT IMPEDANCE
SPKR SPKR SETTING
16Ω + None = 16Ω
16Ω + 16Ω = 8Ω
8Ω + None = 8Ω
8Ω + 8Ω = 4Ω
4Ω + None = 4Ω
W. IMPEDANCE SELECTOR — (Head Amps)
Select the speaker output impedance that
matches the total impedance load of the
speaker configuration you have chosen from the table
above.
