2017年2月23日 · Hello. I have a Yamaha amplifier which I used to have hooked up to my stereo. It worked fine. Via a dual red n white cable. But the stereo broke. So I tried to hook my laptop, phone to it. Via a 2 in one cable. So 2 in one at one end and a red n white at the other. So I plug the 2 in 1 into my phones headphone jack and the dual end into the amp.

2018年2月26日 · for some reason i totally forgot about the mic input being in there as well. won't be the best sound but with an adapter you could get sound to come out of the phones speaker. personally i'd invest in a cheap speaker to plug the source into. for instance when i was deployed i bought a $10 set of pc speakers to take with me. we plugged in all kinds of stuff into it like laptops for movie night ...

2018年2月14日 · If the same speaker is not working then the problem is in the phone preamp of the stereo. If the other speaker is not working then the problem is in the turntable. It could be the RCA plugs. Very common for the wire to break where it enters the connector. You can replace both RCA connectors. Most require soldering but there are some that don't.

2012年10月4日 · Hi, I have a Technics SA-DX 1050 amplifier from 2001. When I hit test mode, all the speakers output noise normally. However when I connect TV/ DVD/ phone into any of the inputs, sound comes only from the left speaker. If I put the volume up to high, I can hear noise coming from the right speaker...

2016年8月27日 · My example would be the JTR Noesis 212HT which has a sensitivity rating of 101dB/2.0v, which means one watt of pink noise and that speaker will play 101dB at one meter. At 32 watts it'll be around 116dB at one meter and with two speakers at …

2013年4月12日 · - I have tried replacing the A/V cable and that did nothing. I have tried testing the speakers out on my phone instead of my laptop and the speakers still are dysfunctional (so it's not an issue of my computer hardware). Basically, it comes down to something being wrong with my receiver or something being wrong with my speakers.

2020年7月26日 · I have an old jukebox with limited speaker output (switchable 2W, 4W, 8W, 20W). I would like to connect it to a 100W bluetooth amplifier so I can connect some external speakers to give more volume (and also play music from my phone). Can I connect the old speaker output (presumably at 2W)...

2013年11月12日 · It could be a source of radio frequency inside the shop is inducing voltage onto the cable. It could be a magnetic device (electromagnet or earth maget) near the amplifier or the wire connecting the headphone jack to the amplifier. It could be an impedance mismatch between the amplifier and the headphone jack.

2013年2月5日 · My problem was due to poor shielding in a KVM switch cable. This cable bundles both the speaker cable and the monitor cable within the same wire. There was cross talk (interference) between the signal going to the monitor and the signal going to the speaker, which (mostly) didn't show up until playing certain 3D games.

2020年3月15日 · I have a Marantz amplifier with a USB (socket type B) DAC input. How can I send digital audio from a Samsung J1 Android phone out via USB? I have bought an adapter from USB-A female to USB-B male, but when I connect everything the amplifier does not see any input.
