What's not working about them? The only thing that should be hooked up to a phono input is a non-amplified phonograph. Phono inputs usually have a preamp attached to them that will cause other signals to be over-driven and become distorted if they are used.

My 1974 panosonic turntable has a low volume out of the receiver.


Are you sure you are going into a phono preamp? Turntables cannot work correctly if connected to the receiver's aux or tape input as they require much more volume boost which the phono input privides. Not many newer receivers have a phono input but an external phono preamp can be added (usually under $20)

My receiver works fine when I plug my iPod into it, but when I plug my turntable in I can't get any sound. Any idea?


The phono cartridge on your turntable puts out a much lower level signal than your iPod. Back when turntables were popular, all receivers had a special phono input to take care of that. Your modern HK receiver does not have a phono input, so you need to get an external phono preamp. Plug the turntable outputs into the phono preamp inputs, then plug the phono preamp outputs into one of the audio inputs on the HK, like where you connected the iPod.

I recently bought this turntable used. I am trying to connect it to a Sony receiver with a phono input, but no sound comes out when connected. Does this turntable require a pre-amp or something?


If the unspecified Sony has a "PHONO" input you should be good to go. What model?

"PHONO" is the only designated connection on an audio device that is literal and exclusive. Nothing but PHONO will work right on it and old-school turntables would require it to preamplify and frequency-correct the tiny current produced by a Phono cartridge. Look up RIAA equalization.

If your unit doesn't have a PHONO connection AND your TT doesn't have a self-contained preamp you will have to get a Phono Preamp to connect between the TT and any Line Level input, like Aux.

I have a T62 Stanton and I want to play it like a normal turntable. I conected it in the Behringer mixer using L/R cable. I cannot hear the bass sounds with my headphones. What is happening?


Is it connected to a "PHONO" input or something not labeled explicitly for PHONO?

Phono plays lower in volume than cd and tuner. Sounds ok i guess but is about a quarter to one third lower in volume. Is this normal ? Can I plug phono into cd jacks to check if any better ?


Hello. As per the post before me, if you have a receiver with a Phono input(many receivers don't have one anymore) the output of a phono cartridge is around 30 millivolts, vs 300 millivolts for a CD(10 times the amount) or any other line level device. A Phono preamp, also has RIAA(recording engineering standards)Equalization that provides the proper equalization for a Phono cartridge. As per the other post, yes, it will sound very low, and unnatural sounding. If the input you are plugging the turntable input into, doesn't say Phono, you can purchase an inexpensive Phono preamp made just for this very issue. You can try Radio Shack, or find something of better quality on the Internet.

Loud distortion through phono inputs


Phono inputs are designed for turntables only. Any other device will provide too high a signal for that input to handle. The phono input has an extra amplification stage built in. The distortion is because of the high suignal level being supplied to the input. The only way to get this to work properly is to purchase an antenuator which will decrease the signal level to the phono level.

Old turntable works but is too quiet to hear


It sound like you may have to hook your turntable up to a phono input. Turntables have low level outputs. The phono input is designed to amplify this low level more than the cd/dvd inputs do. If you do not have a phono input, you can buy an external "phono preamp" online. Hope this helps.

Cambridge A5 Amp, only one speaker works when phono selected


If both speakers work okay on other inputs .Then cable from pre-amp to amp and main amp are okay. If phone RCA jacks go directly to electronics board .Then its possible solder on phono jacks need to be resoldered or other connections in that section.If unit needs repair you can also purchase a phono preamp from radioshack hook up your and use it on other good inputs such as CD etc..Please note PHONO inputs are only for turntables .If a non turntable input such as CD,TAPE,TV Etc is used on PHONE .Then you will overdrive this input .

Hi ,Marantz SR7200 , i am getting an audible hiss on phono inputs and digital optical inputs . If a connect something to the front phono inputs , however there is no hiss , any ideas ? Thanks in advance .


if your hooking up a phono input lead to a digital input lead it won't work analog and digital totally different setup. when you connect the leads up it just kills the input amp so there is no noise.

Do not connect your PC output to the Phono input, it is a mismatch. Thye output from the PC will be "line level" or the same level as tape input, aux input, CD input etc. The phono input line contains an extra stage of amplification required for turntables. If you attempt to use that input, you will fry it. Any of the other inputs on the receiver will work for you.
