To: All Infinity Service Centers

Model: Basslink (version w/o AUTO-ON switch or REMOTE GAIN)

Subject: Unit will not turn off

In the event you receive a Basslink subwoofer with the complaint: “The unit will not turn off, even when the audio signal is removed, and the Remote power connection is switched off” (indicated by the Basslink’s red LED remaining ON), perform the following modification:

1)Set the unit on a padded surface and remove all external cables.

2)On the amplifier faceplate, remove only the (14) Phillips mounting screws as shown in Figure 1.

3)Remove the amplifier assembly from the enclosure. If the amp is turned around and supported correctly, no other connectors need to be unplugged.

4)Add these two components:

1.0 Meg ohm 1/8W resistor, Infinity part# 299-1M

.01uf, 100v mylar capacitor, Infinity part# 140-PF2A103F

Solder these parts in parallel (See Figure 2); and attach to original location shown (See Figure 3), which is in a narrow cavity between main power supply caps and transformer T101. There are two empty pads on the PCB for these parts with marked designators R272 and C273.

5)New gaskets must be added to the amplifier mating surface; two pairs are required, four gaskets total: Infinity part# 723D150 and #723C150

6)Replace the amplifier assembly and tighten all mounting screws. Use caution; a hand tool is recommended to prevent stripping the threads in the enclosure.

7)Connect +12v to the unit and a signal cable, after the unit cycles ON, (red LED should be lit), remove the signal and remote connection only (or shut off the music source if using the Universal Interface). Unit should turn OFF after 3 - 10 minutes (as indicated by the red LED turning OFF).
