Transducer Troubles!

post #1 of 15
Thread Starter 
Recently I purchased a Clark Synthesis TST209, along with a Pyle Home PAMP1000 amplifier. I have a Denon AVR-1513 receiver with Boston Acoustics 5.1 speakers. Before installing the transducer to my couch I hooked up everything to ensure it worked properly. Let me say that when it comes to audio electronics, I'm a complete noob! Good with all other electronics, except audio, so please bare with me if I slaughter certain terms or seem confused.

I wired up everything as per the Clark Synthesis manual, "Y" adapter from the receiver feeding the sub woofer and to another "Y" adapter. The second adapter has 2 composite RCA cables hooked into it(red&white), which are then hooked into the back of the amp. The TST209 is then hooked into the output speaker posts accordingly.

Initially I thought either the amp was busted, or the TST was. I spent a few hours trying different wiring configurations. On the front of the amp there are only two knobs, left/right balance and volume. With my receiver on, using the test tone for the subwoofer, nothing was happening even with the amp volume maxed out. So I increased the volume on my receiver. It wasn't until my receiver volume passed 61-63 that I heard the amp click and the TST209 began vibrating, albeit incredibly low. Going up to 80 it began to slowly vibrate on my hard wood floor. At 90(max) it was distorted and sounded horrible, yet wasn't very loud.

Not impressed, I decided to try hooking the RCA cables to my TV output to the amp to see if the TST209 performance improved. I was shocked that it actually worked(functioned, not because audio out works from a TV), even though it played all ranges of audio, including bass.

My question is: Why can't I have this sucker hooked up to my receiver? Is the amp not powerful enough coming from the receiver? I'm at a loss. Using the amp with audio out from the TV is very loud, and it gets my whole couch vibrating...but all I want is bass coming through, not everything at once.

I hope some of the forum members can point me in the right direction!!!

Im no pro by far and I'm fairly new to all this myself but to me it seems it may have something to do with your receivers settings. The point were your sub takes over the bass for your main speakers. Where is it currently set 80hz?

Tried that. From 80 to 250 HZ no change

Did u try hooking up the amp to a speaker to see if it works? Because there's no way the tv outputs are gonna have more power than the amp.

When hooking both the receiver and tv output, both were going through the amp. I'll hook up a speaker to it later today and test it.

It sounds like you have a level issue somewhere.
Try only hooking up the shaker to the receiver sub output to see if it's a cabling/splitter issue.
Also, make sure you don't run the amp bridged into that shaker, Pyle amp power ratings are likely shaky at best and it's only 8 ohm stable when bridged.

Ran it directly from the SW output to the amp, still doesn't kick in until the receiver volume is almost maxed out. 63/90 volume.

I don't have any wiring that would allow me to hook it directly to the sub output on the receiver. A speaker wire to composite connector?

I've unplugged all speakers on my receiver, with only the amp and shaker hooked up so I can run movies/games to test it out.
Maybe I've misunderstood the whole shaker subject, but on most movies the shaker isn't felt until about -30.0dB, it feels pretty effective around -20.0 to -15.0dB. Now if I had the rest of my surround speakers hooked up at those dB, my ears would be bleeding. Would a "good" amp allow me to adjust the gain so I can feel the shaker without waking up the neighbors?

Your sub and pyle amplifier should both be wired to the subwoofer out on your receiver, via an rca splitter.
Unplug the subwoofer and try it with only the amp (powering the shaker) connected to the receiver sub out via rca.

That's how it's hooked up right now. The volume knob on the amp is on the max setting

Anyone think I should buy a amp with a higher watt output, since the Pyle PA1000 is only outputting 80 watts @ 4Ohms

Yes, but you also have a level issue of some sort.

I believe people operate the above outside an enclosure safely, but I can't say for sure.

Edit: 80 watts actually isn't too bad for a 100 watt shaker.

Well I think I've found a reasonable compromise. I've gone into the speaker setting on my receiver and lowered the levels by 12dB on all the speakers. So I can now have the whole system on at -20 to -10dB with a good level of shake and overall sound. So with that amp you posted, mik James, would definitely give the shaker more oomph?

PS - I really appreciate your input thusfar

Would likely give the shaker a little to much oomph tongue.gif
Glad you found a compromise smile.gif
