Humming from speakers when CD player running

Hi i have a Technics 200 watt receiver/amplifier and 6 disc (cartridge) CD player connected to my Sony speakers. The receiver/amplifier only had a connection for 2 speakers, and i have 4, so I wired two speakers on each connector. the prob is there is a loud humming from speakers when i have the CD player on..is there a solution for this?

Yes, The humming is always there you just can hear it better when the cd is playing. The humming is caused by the electrical system in your car. There is an inline filter you can buy and insert it between the car's power source and the head unit. I had a head unit I bought that was absolutly terrible until I installed that filter. Also if you did a do it yourself job on your amp wiring it is usually best practice to run your RCA cables on the opposite side of the car as your power cable. You can also purchase shielded spark plug wires which is a source of noise usually of a different kind tho. First make sure you have a good ground. This means that you have grounded your amp to bare metal not painted metal. If that didn't work put in the inline filter on the head deck as they are only $20 available at radioshack. If that doesn't work, go back an wire your car right this time and put the power and RCA on opposite sides of the car. If you still have that hum it may be the spark plug wires but that sounds more like static than hum. You have a text book case of alternator hum... Hack

hi,
You have to check the ohms of the speakers all spekers should be 8 Ohms or above. if not it will overload the amplifier at high level. The minium ohms impedence of the amplifier is 4 ohms. If you connect two 8 ohms speakers together then the effective ohms will be 4 OHMS then the amp will handle the speakers. If you connect two 4 ohms spekers together then the effective ohms will be 2 Ohms, this will overload the amplifier. You will be able to connect two 8 ohms speaker to left channel or right channel of the amplifier. Check the speaker spesifiction to know its ohms. Make sure all the speakers have an impedence of 8 OHMS or above
OK

If you are getting a hum from the speakers when you touch the red wire that means the amplifier is working and is connected to the cartridge. I don't think it is a short unless you get a hum if you touch the white wire as well. I think it is a dead cartridge, or damaged stylus. If you touch the stylus does it make a sound, if not it confirms it is a bad cartridge, only solution is to replace the cartridge. Kiri

Hi there i jus wanted to know if the aiwa lcx 337 k has RCA connections so i could connect my mixer to it, and also if i could run 200 watt technics speakers through it aswell? cheers


No external tape loops. This is NOT a component system in the usual sense.

Wattage is not THE major consideration, impedance is.I can't find any documentation on this product but these small units are usually spec'd for speakers with less than 8-ohms to tweak the power output figure at a dreadful distortion level. All other things being equal, 8-ohm speakers would require more power so you'd have to crank it more. Overdriving any amplifier (like this one) will create speaker-killing distortion.

Don't run anything but a TURNTABLE through Phono. That's the only labeled input that's literal. Use any other Line Level input for the CD.

If you don't have anything connected to the Tape loop, use the Tape In connectors.

Do we need an amplifier to connect home theater yamaha nsc150/e105 with TV, DVD, PC.plz explain


Yes, you need an amplifier, since the "levels" of the sound-output from each device (TV, CD-player, cassette-player, Sony mini-disk player, turntable) are not sufficient to physically move the "cones" inside your speakers, to push air around, to produce sounds.
You need "watts" of power to push air, while the devices produce milli-watts (watts/1000) of power.

Also, the amplifier is also a "decoder", electronically processing the input to produce "5-channel" (left, front, right, back-left, back-right) surround-sound output.

Can I install 4 6 ohms speakers on an 8 ohms a/v receiver? receiver Sony STD HD 800 speaker system: Jamo S413 HC S5 Home theatre system,


Best Answer - Chosen by Voters An ohm is a unit of electrical resistance. You can think of it as your speaker will impede or pull 8 ohms from the amplifier that is powering it.

8 ohms is less resistance than 4ohms. So a 4 ohm speaker would require more juice than your 8 ohm.

If this is the only speaker, then that's all the resistance you have to worry about handling. If you had two of these speakers wired in parallel, then the total impedence would be up to be 4 ohms, because each speaker actually reduces the resistance in the circuit...so 8 ohms + 8 ohms = 4 ohms.

You use this information to make sure your amplifier is powerful enough for the speakers. If the speakers have too much resistance, they'll fry your amp.

Here's a good sentence to help explain, but I recommend reading the article I linked in sources...

"An amplifier designed to put out 100 watts into 8 ohms will put out 200 watts into 4 ohms. Two 8 ohms speakers wired in parallel (4 ohms total) would cause the amplifer to produce 200 watts." Source(s): http://www.marktaw.com/recording/Electro…

This is a player only that requires a receiver or pre-amp/amp combination to drive speakers. The output from this unit is what is called "line level" and can be connected to any CD/DVD/VCR or TAPE input on a receiver.

SX-1600 + KD-491F


Appreciate the additional information.

To recap what you need is a receiver that can accommodate:
4 - Pioneer S-DF1-K (15-100W, 8 ohms)
1 - Pioneer PD-F407 25 Disc CD Player
1 - Pioneer CT-300 dual tape deck
1 - Kenwood KD-491F turntable

Possible choices are (keeping in mind that the power output should be less if not equal to 100 watts and a turntable/phono input):
i. Onkyo TX-8522 Stereo Receiver;
ii. Yamaha RX-397 100 Watt Natural Sound AM/FM Stereo Receiver;
iii. Sony STR DE695 AV receiver;
iv. Teac AG-790 200 Watt Stereo Receiver;
v. Denon AVR 888 - AV receiver - 7.1 channel.

Some of the above also includes feature(s) to hook up to your video system. Some may even require a fifth speaker (subwoofer).

Incidentally, you can also choose another brand/model even without a turntable/phono input. As initially posted, a turntable/phone to line level pre-amplifier is only required. Here are some examples:
a. XP200 Turntable Preamp - Nano Series;
b. Pyle® Pro PP999 Phono Preamplifier;
c. Pro-Ject Phono Box Turntable Preamplifier;
d. Radial J33 RIAA Turntable Preamp Direct Box

Good luck with your project.

High distortion


The head unit may be rated at 200 watts but it cannot produce more than ~20 watts of real power per channel. There's no way that it can drive the high end speakers to a level that will be needed to compete with the subs on a 1000 watt amplifier.
