The music on my table is real low. I replaced the phono cable to see if that was the problem, and it did not cure it. I need some suggestions.

The unit will have a pre-amp for the phono only. If you plug in a RCA cable with a phono plug on the other end if you touch the end of the plug with your finger (with the unit on) there should be a buzz on the channel. If you don't get any than the pre-amp will have gone. They are generally a small IC and some minor components. Search back from the socket and the first board you come too will be the pre-amp. Replacing the IC will often cure the problem.

You need to buy a phono preamp to add in between the LP player and the music system. Can connect the LP player output to the phono preamp input and output of the preamp to the aux input of music system.

If your turn table has a magnetic cartridge it will not work,Becuase the ner recievers are not equip with a phono preamp, They are equip to only use a crystal or ceramic cartridge in the turn table.

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.

I can't find anything about the HT4 but it should be connected to PHONO (nowhere else) if it has a moving magnet cartridge and you should set the PHONO/LINE selector to PHONO.

The bose as most all in one systems do not have an inbuilt phono stage. Phono especially MM type have a very low signal and an eq curve that gets altered in the phono stage. Without a phono stage (known as a phon pre amp) you will not get much fun from your turntable. To connect : turntable out - into phono preamp - phono pre amp out into bose line in/aux in

I would be very surprised if you have a phono input on your sound card.What you need is a phono preamp because the signal level coming from your t.table is too low for the line input,You can find it in any electronic supplier like radio shack. Have fun

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.

Hi,
You may have a bad cable. Go pick up one of those cables designed for iPods that plugs into the headphone jack on the player, that ends with two RCA plugs. If that cures it, the other cable was bad.
The BEST way to do it though, is if there is a docking station made for your player that has RCA connectors on the back, so that you can use normal RCA cables.

You will need the following to connect this to that system:

1) Phono Pre-amp
2) 3.5mm to RCA adapter or 3.5mm 'Y' cable to RCA
3) Turntable

Your turntable will connect to the Phono Pre-Amp input. This pre-amp will also have an output. This output is RCA, from here you connect to your system using the 3.5mm adapter or cable.

That's it.
