4.0 Hardware Installation

4.7.9 ZONE 4 LINE OUT output

The ZONE 4 LINE OUT jack provides a line-level output that
duplicates the program material on LINE 4. This may be used to
feed another Bose® amplifier installed for a large zone. The 12V
control output is used to connect to Bose amplifier sequence
inputs.

4.8 AC power connections

The rear connection panel of the chassis provides an input volt-
age switch for 100V, 120V, 220V, 230V, or 240V use. Check the
switch settings to be sure it is appropriate for the local power
standard.
WARNING: Be sure to disconnect the unit from AC power before
changing the input voltage settings on the rear connection panel.

4.8.1 Fuse type

Be sure the proper supplied fuse is inserted in the fuse holder.
Replace the fuse as needed with the proper type. 100V and 120V
units require a T6.3(6,3)A L 250V fuse. 220V, 230V, and 240V units
require a T3.15(3,15)A L 250V fuse.

4.8.2 AC POWER connection

Insert the proper power cord for the voltage used in your region.
