Have an RX_V371 that I use for cd's. Just bought Audio Technica turntable with phono preamp, thought I had it set up but almost no sound coming through?

If I put my ear close I can just hear music. Tried playing around with different placements, have tried RCA cable in both audio 1 & 2. Tried various input levels.

There is no phono input on unit. If you wish to use turntable you willl need to buy a quality preamp, and appropriate cables.

Testimonial: "Turntable has built in preamp."

No sound ? Make sure the audio input cable is connected to the music center FIXED outputs, the black connector is fully seated in the music center SYSTEM CONTROL 1 jack, and the multi-pin connector is firmly seated in the Acoustimass module jack. ? Turn the music center off for ten seconds, then on again, to reestablish communication between the music center and the speakers. ? Check the connections for any external components. Make sure to select the correct source for the desired input. ? Check the speaker connections. ? Be sure the CD is placed correctly, label-side up, in the music center, and the cover is closed. ? Increase the volume. ? Check to see if MUTE is lit in the display. Press the MUTE button on the remote to unmute the sound. ? Disconnect any headphones. ? Connect the FM and AM antennas , and last but not least. Make sure there is power going to the remote speakers or the unit will not communicate with them. Good Luck

SOURCE: Receiver shut down only when using phono preamp

Since the protection circuit trips after 4-5 songs at high volume from LPs, it may be that the infra-sonic rumble common to phonographic recordings is driving your amp stages much harder than it sounds like they are driving. You can check this with watt meters for your speaker outputs, or by filtering such extremely low frequencies on the input. If you have an equalizer--especially an old one--it may have an infrasonic filter, or just cut the very lowest frequency available on the equalizer after running your phono pre-amp into the EQ and the EQ into your VCR2 input. This setup will verify if your problem is the infrasonic rumble, but I wouldn't use it as the solution. There are very quiet infrasonic filters available that would work better for the long term. And if you just cut the lowest EQ frequency out, you'll miss some good bass.

SOURCE: TURNTABLE PROBLEM

You have a VERY nice turntable! TWO quick questions: 1) How do you define "minimal" volume? It is not NECESSARILY unusual that your turntable / receiver combination will have lower volume than your tuner, CD or DVD player. What happens when you CRANK IT UP?! Don't worry about the position of the volume control! 2)Are you changing the turntables output settings via the switch under the platter? Please post a reply and we'll go to the next step! Note: Ceramic cartridges are pretty much extinct. They were strictly low-end, low-cost, low-fidelity devices used in cheap audio systems of "yesteryear". Have you ever seen a BSR or Garrard turntable? Or your grandad's Magnavox Console Stereo? THAT'S where you'd find a ceramic cartridge!

Ditto. Double check the ground cable. If it is connected, then try a different set of RCA cables. Also check the connections on your headshell/cartridge. Make sure all 4 wires are properly secure.

is the wire loose on either end? sometimes the electrical plugs can cause noise due to resistance, so trying different outlets might help too

No sounds coming from my Sony PS-LX250H

you will an amp . this unit is supposed to a preamp., making it line level.
The Sony PS-LX250H's built-in phono preamp allows you to use the turntable with any receiver, HTIB, or computer sound card by plugging the turntable's cables into any line-level input, such as auxiliary or VCR. If your receiver does have a dedicated phono input, we recommend using it instead of the turntable's internal phono preamp (which can be turned off). Chances are, the turntable will sound better that way.

Can i connect a turntable to a JVC RX-5020VBK receiver?

With a bit of effort: This receiver has a variety of auxiliary or "line" level audio inputs (CD, VCR, etc.) but none designed for a phono cartridge input. You would need an external phono preamplifier in between the turntable output and one of the JVC inputs to have sufficient audio level. (Some newer turntables come equipped with such a preamp, but most do not.) They cost from $20 to $50 from a variety of suppliers (MCM, Parts-Express, etc.)

Onkyo TX 8020 Receiver sounds muffled. I have the Onkyo TX 80202 receiver and just bought the Audio Technica AT-LP120 turntable to connect to it. I have the turntable switch to "Phono" (so as to make use...

This sounds like a wiring problem. Perhaps a faulty earth connection inside the lead or the plugs to and from the turntable. Also check the connections to the cartridge, they can become loose or be connected wrong. Say a channel to the earth connection.

The sound is really low if i press the aux tape cd phono or vcr the sound is there but really low

Instructions:
Evaluate your current receiver. Take a look at the back-panel connections to make sure you don't have a phono input. In most cases, the phono input will be clearly marked. If the connections are not marked, look for a set of RCA-style inputs with a grounding screw next to them; this is a phono input. If there isn't a phono input on your receiver, see if you have an open set of RCA inputs. If they are all occupied by other equipment, you can disconnect one piece of equipment, buy an A/V switcher or get a new receiver--preferably one with a phono input.
2 Purchase a phono preamp. The voltage output of a turntable is much lower than those of other peripheral devices, including CD players, tape decks and game systems. Although the inputs look the same, connecting a turntable to a standard RCA audio input will result in very faint sound output, if you hear anything at all. The output of your turntable must be amplified to a level of about 150 millivolts (mVs) before it reaches the receiver, so a turntable "pre-amplifier" or phono preamp is necessary.
3. Purchase patch cables. You'll need a set to run from the preamp to your receiver. Measure how long your cables need to be, and purchase accordingly. Resist the temptation to "go cheap," because better-quality cables will provide better sound.
4. Connect the preamp into the system. First plug the preamp into an AC power outlet. Most models have a small AC-to-DC adapter built into the plug. Then connect the cables from the turntable to the preamp, and connect your new patch cables from the preamp to the receiver.
5. Adjust the gain of the phono preamp. Most models have a gain control for fine-tuning. Follow the instructions provided by the manufacturer and adjust your system accordingly.

How do I connect a technics turntable to an RX-V463 AV reciever? Thank you in advance

Modern AV receivers rarely contain PHONO preamps.

A traditional turntable requires a preamp inline with it to PRE amplify and frequency-balance the minute signal produced by it's cartridge. Most stereo receivers and preamps have Phono connections and internal preamplification strictly for that purpose. Yours does NOT.

A standard turntable will require you to acquire an external PHONO preamp to place between the TT and an Aux connction on the receiver.

Some of the newer turntables come with selectable internal preamplification to solve the lack of it in modern equipment. If your turntable is that type you can select its internal preamp output and run that to an AUX input.

I have an RX-V663 audio sounds flat

Let's deal with the turntable sound first - unless it's a self-preamplified model you would have to get an external phono-specific preamp to use with this receiver. Without one you'll get microscopically weak, tinny sound from the turntable. Google "RIAA curve" to see why.

As far as the CD sound through the Blu Ray player... for one thing it is flat, as in two-dimensional stereo. Compared to genuine surround from a movie it would be a letdown.

Can you better define 'flat'?

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.

Dave

Distorted sounds

The AT-PL120 uses a magnetic cartridge to extract a music signal from the record. Magnetic cartridges all put out a very weak electric signal, and so their output must be strengthened, or amplified, to where it is as strong as the input from, say, a CD player. This amplification is provided by a pre-amp. If your receiver has dedicated "phono" inputs the pre-amp circuits are already in the receiver. If you do not have dedicated phono inputs you must either buy a pre-amp, or buy a magnetic cartridge turntable with a pre-amp built into itself. The AT-PL120 has a built in pre-amp. You can switch the AT-PL120's preamp on or off. The switch is located under the platter at the back side of the turntable. Take the platter mat off and turn one of the platter's holes to the back and you should see the switch through the hole. If you push the switch to LINE OUT the preamp is turned on and the turntable sends an amplified cartridge signal out the cables which MUST be connected to a receiver inout suitable for a CD player (a "high level" input). If you push the pre-amp selector switch to PHONO OUT the turntable sends the weak unstrengthened cartridge signal out the cables which MUST be connected to the receiver's dedicated PHONO inputs so the signal can be amplified with the receiver's own pre-amp circuits.

If everything is set wrong (i.e. LINE OUT (pre-amp on), and connected to phono inputs) you are applying two steps of strengthening to the turntable's signal which is too much. The resultant sound will be garbled. Try not to do this!

The other way to do everything wrong is set the pre-amp switch to PHONO OUT (pre-amp off) and connect the turntable's cables to a high level input. If this happens the turntable signal receives no amplification and the resultant sound will be thin and weak.

No sound from my record turntable into my computer.

If you're certain there is no sound going out of the TT...

Setting the Pre-amp Switch
For increased flexibility of use, this turntable has an internal
stereo phono pre-amplifier. The Pre-amp Selector Switch
is located under the turntable platter, in the rear-center
(Fig. 1). If the system amplifier you are using has a PHONO
input, set the Pre-amp Selector Switch to the “OFF”
position. If your amplifier does not have a PHONO input,
set the Pre-amp Selector Switch to the “ON” position and
connect the turntable’s output cables to the AUX or other
high-level input on the amplifier (described later).

Turntable operates, but no sound at all
1. The stylus guard is still in place.
2. The tone arm Lift button is pressed in.
3. Amplifier controls set incorrectly: wrong input selected,
tape monitor on, speakers switched off, etc.
4. Check the stylus on phono cartridge for correct placement.
Refer to the instructions for replacing the stylus
on page 5.
Turntable operates, but no sound, or sound not loud
enough
1. If the turntable is connected to an AUX (high-level)
input: The Pre-amp Selector Switch may be set to the
“OFF” position (phono-input level).
2. The input gain of the amplified speaker or similar
device may be too low.
3. The stylus assembly may not be fully seated in the
cartridge body.

You could also isolate the problem to either the TT or the PC by trying the TT on some other sound device like a receiver. Make sure the PreAmp Selector switch is ON and plug the TT into any AUX, CD or TAPE input.
