Do a check, but I do not think that this system has a low level Turntable input. The typical turntable has an output of about 5 mV at peak. The typical sound level of a CD player or whatever is more like 600 mV. So you need a pre-amp t boost the level. The recent resurgence in popularity of vinyl has caused this and modern amplifiers forgot about phono inputs. More on the second link. bvelow. Sony DAV HDX279W SpecsWhat is Phono Preamp Audio Advice
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.
Have a look on the back input panel of the sc-dv290. Check for a "PHONO" input. If there is no phono input it will not play turntable. If there is: then plug it the turntable in and switch the SC-DV290 to PHONO mode.
Another way would be to purchase a "phono preamplifier" from ebay: Hook the turntable into the phono preamplifier, and the preamplifer into the SC-DV290 AUX input.
A turntable use a magnetic cartridge and its output is only 5 to 10 millivolts.A moving coil cartridge is even lower,.2 to .5 millivolts(thats 1/2000 of a volt)in contrast, a mp3 puts out a 300 to 900 mv signal..so does a CD player. Your turntable does not have enough signal.You need to get an amplifier that has a phono input. Years ago,radio shack used to sell phono preamps that could plug into a tape or cd input.The other option is to buy a used mixer that has a phono input.The mixer output can drive the cd input easily,as the max output from a mixer is 1.5 volts to 2 volts.
is your surround system has a phono input? because most of the turntable can only work with the unit that has a phono input, phono input has a a built-in pre-amp. so if you're only hooking your turntable to an ordinary input then this might be the case, you won't hear any sound or sometimes weak sound.
Most if not all turntables would need to be connected to a PHONO INput which is high impedance with a high gain pre-amplifier stage. It will not work when connected to an AUX, CD or any line level inputs. Alternately, if your amp does not have any Phono Inputs, you can feed the turntable output to a preamp which can then be connected to any any line level inputs. An example may be found here or here. Additionally, there are some turntables with a built-in preamp.
Hope this be of help/idea. Pls post back how things turned up or should you need additional information.
