TEST PROCEDURE 9. AmpLink Output Level and Frequency Response Test 9.1 Connect a 32 ohm load to the amplifier output channels. Set the rear panel 70V/100V dip switch to 100V. All other dip switches should be set to the LEFT. On the UUT rear panel, set the Input Select rotary switch to position 3, AmpLink inputs 1-4.

TEST PROCEDURE 13. Input Priority Test 13.1 Using a CAT-5 cable, connect a Bose CC-1 ControlCenter Zone Controller to the ControlCenter ® RJ-45 jack on the rear panel. Refer to the table on page 12 for part numbers for the CC-1 controller.
TEST PROCEDURE Hi-Pot Test THIS IS A MANDATORY TEST Note: If the unit under test requires disassembly as part of the repair, it MUST be Hi-Pot tested before being returned to the customer to ensure that there is no potential shock hazard. This test requires a Hi-Pot tester with a ground bond attachment to perform this test.
FIRMWARE UPDATE PROCEDURE Download and install the PowerShare Editor software from the http://pro.bose.com web site. This software is located on the PowerShare product page. Note: The PowerShare Editor software is compatible with Windows PC’s only. Connect the Amplifier The PowerShare Editor software communicates with the amplifier using a standard USB connection and a standard USB-controlled human interface device (HID).
