SONANCE CABINET SUBWOOFERS
Voltage Selector
Sonance Cabinet Subwoofers are equipped with a Voltage Selector switch that is
factory-set to the proper position for the country where the subwoofer is sold.
Subwoofers sold in the United States are set for 115V operation; subwoofers sold in
other countries are set for 230V operation. The subwoofer’s proper operating volt-
age is shown on the switch itself (see
Figure 5 ).
The Voltage Selector switch is not user-selectable, and has a plastic cover to
prevent it from being accidentally changed. If you need to operate your
subwoofer on an AC voltage that is different from the one showing on the switch,
contact your Authorized Sonance Dealer or Service Center.
Replacing the AC Fuse
Your subwoofer is factory-equipped with the following AC fuse:
115V Version:
Sub 12-250 — 5A, 250V slo -blo ; Sub 10-150 and Sub 8-100 — 2A, 250V slo -blo
230V Version:
Sub 12-250 — 2.5A, 250V slo -blo ; Sub 10-150 and Sub 8-100 — 1A, 250V slo -blo
To replace the fuse, unplug the power cord from the Power Cord Connector and use a
screwdriver to remove the fuse holder (see
Figure 6 ).
CAUTION: FOR CONTINUED PROTECTION AGAINST FIRE, REPLACE THE FUSE WITH ONLY
THE SAME TYPE AND RATING.
Subwoofer Connections
Power Connection
Your Sonance Cabinet Subwoofer features a removable IEC power connector (see Figure 6 ).
(A power cord is included only with 115V versions of the subwoofers.) Plug the female end of the power cord into the Power Cord
Connector on the subwoofer’s rear panel and plug the male end into a grounded wall socket. Do NOT plug the subwoofer’s power
cord into a convenience outlet on any other audio or video component.
IMPORTANT: D
O NOT PLUG THE POWER CORD INTO THE WALL OUTLET UNTIL ALL SYSTEM CONNECTIONS HAVE BEEN MADE AND VERIFIED

Audio Connections
Your Sonance Cabinet Subwoofer has flexible connections that let you use it in a wide variety of audio system configurations. You can
connect the subwoofer’s Line Inputs to a surround processor or receiver’s line-level dedicated subwoofer output or a stereo
preamp/integrated amplifier’s left and right main outputs. The subwoofer’s Speaker Inputs can be connected to the speaker outputs
of a receiver or integrated amp that does not have left and right line-level outputs or a dedicated subwoofer output.
The subwoofer has a pair of Line Outputs that feed the signal to a main speaker power amplifier when the subwoofer is being fed by
a stereo preamp’s main outputs. The subwoofer’s Speaker Outputs feed a pair of main speakers when the subwoofer is being fed by
a receiver or power amp’s speaker outputs. The subwoofer’s Line Outputs and Speaker Outputs are both high-pass filtered at 100Hz,
6dB/octave. This high-pass filter is not defeatable.
To minimize noise interference on line-level cable runs longer than 20 feet we recommend converting the audio signal to balanced
configuration with the Sonance LS2 Balanced Line Sender at the source component, and back to unbalanced configuration with the
Sonance LR2 Balanced Line Receiver at the subwoofer.
When using the subwoofer’s Speaker Inputs and Speaker Outputs we recommend the following minimum speaker wire sizes:
• 14 gauge for a total wire length up to 30 feet
• 12 gauge for a total wire length from 30 feet to 75 feet
• 10 gauge for a total wire length longer than 75 feet
To determine the total wire length, add the lengths of wire between the amplifier and subwoofer and between the
subwoofer and the main speakers.
