Question about Velodyne CHT-8 Subwoofer

Open Question

My cht-8 subwoofer stopped producing sound. I have remote signal turned on when music is playing green light comes on, but no sound. I verified the speaker is still good by directly connecting speaker wire to it and I have sound, so that means something in the circuit board area is bad, don't see anything obvious need a place to start.

Logitech Z313 Speakers stopped producing sound, I have tried playing music, the green bar showing music is moving (under the speaker button on windows 7), but the speakers are not giving off a sound.


Pretty much the same happened to me. There are two wires coming from the wired remote control. One has a green plug which plugs into your sound system (computer sound) and the other connects to the Sub Woofer assembly. Feel this later cable for a harden section. It will probably be closer to the Subwoofer, but may be anywhere along it. This cable will have been cooked by overheating (Playing sound at full volume for over long periods of time.) . You will feel probably a 6" to1' section that is a tad stiffer and the plastic will crumble. You will need to cut a few inches into the normal cable and remove the bad section. Then strip and tin, the cables and connect them individually . Connect (tin, solder and seal them individually: ground to ground, white to white, red to red, blue to blue, green to green, purple to purple). Depending on the electrical tape you use- there will be a thick bulge in the cord, but it should work fine... or you can connect the severed cable to the original source to avoid the bulge ... but I did not want to shorten my remote any more than I had to.

My amp stopped workin, when i turn the stereo on, the green light is on, then when the music starts to play it turns red and stops working,


The red light on amplifier relates to power supply while the green light is indication of sound functionality. An amplifier that allows sound to generate should display both red and green lights. Howeever, some amplifiers would display only green as long as the sound is functioning.

Solving the problem

First, a red light still on means the power connections to the amplifier is fucntional least requirng repairs.

Second, the green ligh should turn on once the stereo were tuned up to produce sound. If the stereo is still on only least produce sound on the amplifier, check on the connection wires between stereo to amplifier that may have disconnected due to woofing or dubbing sound generals with unfirm wiring.

Clicking noise from sub when in standby mode


Disconnect the input. Does it stop? If yes...

It sounds like it's sensing a signal at its turn-on threshold. Figure out why there's signal present when it shouldn't be there.

Exactly how is it connected to the source? LFE-only or full-range signal?

Has light but no sound


The first thing to always check first is the fuse. This will probably involve some disassembly but it is alwayst the cheapest fix and a constant issue.

I have the same speaker and it sounds like its behaving properly.

if you look on the back of the amp, you will find a switch that allows the speaker to automatically switch the speaker on or off based on the level of the audio coming from the tuner that it is attached to. If the switch is set to the auto mode, then it will listen for audio on the line and if the signal level coming into the subwoofer is high enough, the amplifier in the subwoofer will turn on and play. If the signal is not strong or loud enough, then the subwoofer will not turn on. There are two solutions to getting the speaker to work.

1. When you turn on the tuner or audio source that is feeding the Subwoofer speaker, you will need to turn it up loud enough to trigger the circuit in the subwoofer to switch on.

2. Alternatively, you can bypass the automatic circuit and set it to the "ON position all the time. In this position the subwoofer is always ready and waiting and should play any signal that is fed to it regardless of the loudness or volume of sound from the tuner. The switch is located on the back of the speaker cabinet just to the right of the red and black speaker wire connections. It is labeled "AUTO" and the switch positions are labeled ON and OFF.

Hope this helps!
