INSTALLATION
STEP 3: BENCH TEST and OPTIONS
Place each unit on a workspace and connect power to the unit. Check to see if LED

default). Connect an audio source to stereo input one and a monitoring device to the
output. Verify that audio is present. Repeat the process until each channel’s opera-
tion has been verified.
Jumper JP2
To enable the front panel “ENABLE” switch, remove and stow the jumper over
the “Enable Bypass” jumper JP2.
Note: The “Enable” switch is disabled at the factory.
