Not that way, lol

Re: Increasing headphone jack signal level

RCAs are grounded, right? when I soldered the RCAs to the wall plates it was one straight wire, no ground. I have a feeling I'll just end up trying to find a wall plate that's not solder-type but instead has female RCAs on each side of the plate, and running shielded, grounded RCAs through the roof. any comments? would love to fix without running any more wires through the ceiling, but am not sure I can ground the 8ga wire that I already ran?

Re: Increasing headphone jack signal level

They are grounded, but i just don't know how can you use them without it. I mean if you use an rca there are 2 cables lets say red and black, these are the most common i think. So red plug has two wires inside a ground and another one, and same for the black one, so thats four wires, and they don't even work without any of these are not soldered. So if you have 8gauges than you have 2 RCA cables. Is that right? By the way, did you tried the solution that i mentioned before? And i also think the problem is that they aren't shielded.
its a bit home-made solution, but you can try to put some aluminium sheet (i dont know the exact name, we usually use it to put food in it its like a tissue or something, really thin) On the cables they can shield really nice, and i think they use this way to shiled cables, but they are inside...Hope you understand :-)

Trends TA-10 USA $149.00



Before carrying these I bought one to try myself. I dont want to sell something I do not think is going to be a winner. Safe to say I was impressed. I drove my Martin Logan Vantage Electrostatic speakers with this little guy and they sounded glorious. For $149 you cant go wrong.

Trends Audio introduces the mini-size Class-T stereo amplifier TA-10 providing up to 2x15W output with the bundled AC power supply unit. Thanks to the Tripath's proprietary Class-T Digital Power Processing (TM) technology and our special techniques in circuit design and component selection, TA-10 achieves the sound quality of high-end HiFi but in a very affordable price.

TA-10 performs very like Class-AB amplifiers with high fidelity and warm sound. Yet, its power efficiency and physical size is just like Class-D amplifiers. Even it's maximum output power is only 2x15W, TA-10 is actually powerful to push even the floor-stand speakers with sufficient and good control of bass sound. It has no problem for normal home use purpose.

Re: Increasing headphone jack signal level

ok, so I have new shielded cables which have absolutely zero noise over the 50 feet that they span. I plug it in to my mp3 player with no noise, or my laptop (not docked) and zero noise. just perfect sound quality.

problem is, when I plug it in to my laptop while it's docked, or plug it in to my desktop, i still get some noise... definitly not as bad as it was when I had the unshielded cables, but it seems the AC power is fucking with the signal. went out and bought a new sound card and put it in the PC as a test, but the same issue on that card too. have read stuff on the internet about "poorly-designed" power supplies which cause noise... am wondering if anybody else has heard of this, and if anybody knows of any proven-to-work suggestions? what can I do to prevent the AC noise from traveling to the speakers, besides buying some new futuristic power supply?

Re: Increasing headphone jack signal level

depending on your sound card setup/drivers, does your Windows Volume options have any PC (internal) sound inputs?

I had noise like that forever (when I'd jack my volume up in my headphones and nothing was playing you could still hear some static); drove me nuts and I always thought it was the soundcard...found this option called "PC Beep" when I was muting and playing with everything and that was the culprit (turned up too loud).

Re: Increasing headphone jack signal level

it doesn't happen on the laptop when it's unplugged... couldn't be a sound card issue. also note in the post I said I went out and bought a brand new sound card and got the same noise on it once I installed the drivers

it's a tough one.
