Rear Panel
XLR Inputs
Each channel has a female XLR balanced input connector, which may also
be used with unbalanced lines. See
Input Wiring
in the section on
Installation (page 12) for more details. (Note: the XLR input is wired in
parallel with the standard 1/4” phone jack, so that either may be used as a
“through” connection to feed additional amplifiers or other equipment).
1/4” TRS Phone Inputs
Each channel has a standard female 1/4” phone input connector which may
be used to either balanced or unbalanced lines (the input automatically
adapts to either type of input signal). See
Input Wiring
in the section on
Installation
(page 12) for more details.
Circuit Breaker
A circuit breaker is provided at the rear of the amplifier. To reset simply
push the button back to it’s normal position.
Note that the re-initialization
of the World 600/World 1.2’s Power Supply will cause a delay up to one
minute after the circuit breaker is reset.
5-Way Binding Post Output Connectors
Each channel incorporates a pair of heavy-duty 5-Way Binding Post output
connectors. They will accept bare wire, spade lugs, hook lugs, and single or
dual banana plugs. Additionally the binding posts are situated so that when
the amplifier is configured for bridged operation, one dual banana plug may
be inserted across the terminals. See
Output Wiring
in the section on
Installation (page 14) for more details.
1/4” Phone Output Connectors
Each channel also utilizes a single heavy-duty 1/4” output connector. This
connector is wired in parallel with 5-Way Binding Posts, which facilitates
running multiple loads from the same amplifier channel where needed. See
Output Wiring
in the section on
Installation
(page 14) for more details.

Mono/Stereo Switch
The switch is used to “Bridge” the amplifier for mono operation. Maximum
rated power of the World 600 is 600 watts into 4 ohms and the World 1.2 is
1200 watts into 4 ohms.
IMPORTANT:
Never change the position of this switch while
Amplifier is turned on. Doing so could damage your equipment.
Note:
Amplifiers operating in bridge mode require different connections
than amplifiers operating in stereo.
See Bridged Operation
in the section on
Installation
(page 14) for more details.
Installation
Mechanical Consideration
The Stewart Audio World 600/World 1.2 occupies one standard rack space
and is only 15” deep and weighs just 10 and 11 pounds respectively,
making it easier to install and transport than almost any other comparable
amplifier. Still, some sensible precautions are in order.
Always use four screws to affix the amplifier to the rack, preferably using
flat washers as well to avoid cosmetic damage to the front panel. When rack
mounting your amplifier it may be necessary to remove the four rubber feet
from the bottom of the unit (in freestanding installations the rubber feet
must be installed). In mobile rack-mounted installations it is recommended
that the rear of the amplifier be stabilized for additional support.
Thermal Considerations
Cooling of the World 600/World 1.2 is achieved convection, through
heatsinks mounted on each side of the amplifier. In the event that the
chassis temperature reaches 87 degrees C an internal thermostat will open,
turning off the power supply until the amplifier cools down. Although the
World 600/World 1.2’s sophisticated thermal management system makes it
less susceptible to overheating than other amplifiers, it remains necessary to
provide airspace around the chassis. This may mean leaving a rack-space
