Infinity TSS-450 System Questions & Answers
Red light and thumping sound,
If your talking about the thump thump sound thru the sub when in standby mode, here's a fix if your good with a small soldering iron. Remove the amp from the sub. Locate U301 on the limit curcuit. (the small circuit card standing up right)
Replace U301 with a TL074IN (www.alliedelec.com part #248-0012) .35cents +S/H also remove R263 from the preamp board,add a new 1N4148 diode(#935-0242) .05 cents to the pre amp board. Connect the Anode of the new diode to the Anode of D101 and the Cathode of the new diode to the Cathode of D108. Replace amp and test. Thump thump should be gone.
I have the tss450 series. My subwoofer pulses when plugged into the wall. What might cause this?
Just apply the excellent solution of "dskum" that I am reproducing here:

I had the same sub and I started hunting down the problem by disabling \'sectional\' parts of the circuit to find out whats causing the problem. The problem was narrowed down to the small \'limiter\' circuit which is soldered vertically on the Pre-Amp. (The wire from power amp connects to it) As far me, the limiter circuit doesn\'t add much value, if you are careful enough not to push the subwoofer to its peak limits. There is a 7 wire bus which connects the Pre-Amp (top board) to the power amplifier (bottom board). In that 6 wires are just direct connection from pre-to- power amp board. The pre-amp output goes through the limiter. (1st black wire). To remove the limiter from circuit just physically remove the limiter board by de-soldering the 7 pins through which its connected to pre-amp. Also you may\'ve to clean up the glue around to easily remove it. Disconnect the 7 wire connector from the limiter and solder it directly to the pre-amp board. (Only 6 black wires need to be connected.) Check the picture. Also as part of experiment I replaced the power filter capacitors with slightly bigger capacity. (But its not necessary - the glue on the old capacitors made it look like it was bulged - but its not). The white wire (limiter feedback) is not necessary and that can be disconnected or cut off for good. All the popup/crackling/thumping it was making is gone and the sub is working great again. (Yes it was doing so even without any inputs). While de-soldering make sure don\'t apply too much heat. The boards are pretty weak and you might easily damage the solder pads. WhiWh Whil Also don\'t use any kind of diode or mess with it the limiter circuit. Just removing the limiter circuit makes it good. If you use diode to directly connect the pre-amp line to power line as suggested earlier you might be damaging it more than its currently since you are almost connecting to the 42 v rails to it. Also if you google you would come across the service manual if you are interested in the circuit diagram.

Subwoofer pulses every two seconds,
Suggestions:
to rule out a receiver problem
Have you tried connecting the subwoofer to another product, other than the one you usually use ? A computer, I-pod, portable CD player, etc...any music source with the proper cable.
If sub still has problem:
One year factory warranty on the electronics. (with proof of purchase)

The problem is with the
Try turning the gain down on the sub (I would assume you have already done that) and see if that makes a difference, too much gain will also cause the thumping.. When you say they check ok what do you mean? Did you get voltage and resistance values, are they within tolerence? Chances are its a power supply problem as most common problem, the secondary cause is a bad/failing circuit causing intefference in the system.
My Infinity SSW-210 Servo Subwoofer quit working yesterday. The light is on and the fuse is okay but there is no sound coming out. Does the sub have another fuse inside?
Unlikely, but open it up and take a look. Some help here.
