P . FUSE—Protects the amplifier from electrical
faults. Replace a blown fuse ONLY with a fuse
of the type/rating specified on the rear panel
of your amplifier to protect your amplifier and
maintain warranty coverage.
Q. IEC POWER CORD SOCKET—Connect the
included power cord to a grounded AC elec-
trical outlet in accordance with the voltage and
frequency ratings specified above the input
power socket on your amplifier.
R. (WORKINGPRO 2X10C ONLY) EXTENSION SPEAKER
OUTPUTS—Connect
speakers here using Speakon® type
or 1/4-inch speaker cables. Use the
Speakon jack whenever possible to
take advantage of its superior power
transfer efficiency and locking connectors. Both jacks are
full range and wired in parallel.
(WORKINGPRO 15 ONLY) SPEAKER OUTPUT—Internal
speaker is connected here. Unplug and con-
nect an external speaker here if desired.
WORKINGPRO SPEAKER CONNECTIONS
• DO NOT connect a speaker impedance load below the
minimum rating of your amplifier to prevent damage to
your equipment. Read the Impedance Guidelines section
on page 10.
• ONLY connect speakers with a total power handling
capacity equal or greater than the power output rating
of your amplifier to prevent damage to your equip-
ment.
• ALWAYS switch your system power OFF before connect-
ing or disconnecting speakers.
• ONLY use unshielded speaker cable of 18 gauge or
heavier (such as 16 or 14 gauge) for speaker connec-
tions. Shielded instrument cable WILL NOT work and
may damage your equipment.
S. HEADPHONES—Plug in your stereo or mono headphones
here. Use MASTER Volume {N} to control your headphone
listening level. Use MUTE {C} to disable speaker audio
output if desired. NOTE: 75-ohm headphones are ideal
for use with your WorkingPro.

T. EFFECTS SEND / RETURN—Multi-purpose jacks:
EFFECTS SEND provides a preamp output that includes
the onboard tone circuits; output level is controlled by
MASTER Volume {N}. EFFECTS RETURN provides a power
amp input that can be blended in any ratio with onboard
preamp signal using EFX BLEND {J}.
• EFFECTS LOOP—Connect EFFECTS SEND to your effects
device input, then connect the effects device output
to EFFECTS RETURN. NOTE: Set the wet/dry control
on external effects units to the fully WET position to
prevent signal phasing problems. Set the input level on
external effects as close to 0dB as possible.
• MULTIPLE AMPS—Connect EFFECTS SEND on the first
amplifier to EFFECTS RETURN on the second amp. Use
only the controls on the first amplifier—except Master
Volume which will still be active on the second amp, as
well as EFX BLEND, which should be set fully to WET.
• RECORDING OR REINFORCEMENT—Connect EFFECTS
SEND to sound equipment input.
• ACCOMPANIMENT—Connect a CD player or drum
machine to EFFECTS RETURN. Control the input level
at its source and by using the EFX BLEND control {J}.
Use only standard 1/4" mono phone plugs with these
jacks. Use a stereo–to–mono adapter if your source has
a stereo plug.
The Effects Loop circuit is on a "side chain" of the main
circuit (as in studio recording consoles) to provide the
full sound of your instrument AND the diversity of your
effects units. This also reduces noise from effects units
being located after gain in the signal path.
U. FOOTSWITCH—Plug in the optional footswitch here.
Use the footswitch to remotely select MUTE and BASS
INTENSIFIER™.
