In the event you receive an Intermezzo 2.6 loudspeaker with the complaint: “There is no output, and
the LED on the volume control does not light, red or green”, check the items listed below:
Check the 3A line fuse to make sure it’s not open. If open, replace with a 3A MDL (.25 x 1.25) slo-blo fuse,
Infinity part# 80126.
Locate R22 in the power supply section, as shown below.
If value of R22 is not 100k ohms
±
5%, then replace R22 with a 1/2 Watt 100k ohm
±
5%, resistor.
1) Remove the grille and side panel.
2) Extract (7) of the rubber grille retainers shown in the illustration; this can be accomplished by carefully pulling
them out of their cavities with long-nosed pliers or similar tool.
3) Remove the (7) Phillips screws that are now exposed.

Remove the black plastic guard from
the area of concern (loosen (2) Phillips screws). R22 can be checked in-circuit and should be:
