Basslink works for a few seconds after i turn on the stereo, then it fades away. The servo light is always on even when i disconnect the input line and turn the knobs to the min level. What could be wrong?

Hello, check the +15v and -15v on the Switching Power Supply Control board. If one or both are missing, it is probably Q117 for +15v and Q118 for -15v. If one is missing the limit comparator will rail to one side and cause the auto variable volume control to trip the servo protection.

Basslink has no output, but Power LED and Servo LED always on.


One or more of the DC to DC outputs might be bad. Check the
/- 54v on the main PCB and the /-15v on the switching controller PCB.
Losing one side of the 15v will cause the limit comparator to rail and force the servo protection, even with no input signal.

Is the light on the infinity basslink suppose to be red or green

Hello jmw3031,

The Basslink should have both a red power LED and a green servo LED. The red LED should be on when power is applied. The green servo LED should only come on during high-level bass transients. Turn the gain down slightly if it stays on for extended periods.

Hope this helps.

Infinity Basslink killing battery

Both issues sound like they are related to a non-connected or loosely connected remote wire on the Basslink.

If you're using RCA preamp wires to connect your stereo to the Basslink, make sure the remote wire input on the Basslink is solidly connected to the stereo's remote output.

If you're using the speaker level inputs on the Basslink and not the RCA preamps, make sure the remote input is not connected, as the Basslink will automatically turn on when it senses the speaker level inputs are active.

Amp keeps blowing fuse

I have this same problem. You have blown the internal amp. I have had 2 of these do the same thing. There is nothing you can do but report it to infinity and try to get the unit replaced.
