Minimal volume for my turntable

Try plugging in headphones and see if it works that way. Sometimes there are contacts in the headphone jack that get shorted and make the receiver think there are headphones plugged in even when there isn't. Plugging and unplugging them will sometimes clear up the fault.

If your receiver ain't has a phono input and the tt has only a phono output, you'll need a phono to line line riaa amp , between the units.

A turntable can NOT be connected direct via a tape input on any amp. Magnetic Cartridges require a special socket often called a "phono" input. If your receiver doesn't have a dedicated socket, by the sound of it doesn't, then you need to get a magnetic cartridge pre-amp. The turntable will plug into this and that will plug into the tape input on your receiver.

Assign the input. Page 22.

Depends on the record player (turntable). If it's old-school it will need a PHONO preamplifier to raise the level and frequency-balance the output according to the RIAA curve. Otherwise it will be uselessly low in volume and tinny sounding.

Phono preamps are available at a lot of electronics stores online. Google it. If you have an old school receiver with a PHONO function you could use IT for the TT and send its output to the Denon.

If it's a newer TT it may have its own internal (selectable) preamp. Then it would drive any standard Line Level audio input.

hi you need a Phono Input Attenuator Line Adapter
the above link is for one on ebay but they are also available through radio shack

You may have two possibilities depending on the configuration of the turntable.
Your Denon should have inputs marked for 'Aux,' 'Line' and possibly, if it is built with the expectation of use with a turntable, 'Mag' or 'Magnetic.'
Your turntable may have a 'Line' output or only a shielded cable carrying a very small voltage from the magnetic head. I assume the pickup is magnetic and not crystal which has a much higher output level but also a higher impedance that requires a matching input.
You should have any of the above outputs in pairs and if the color coding conforms to current standards, there should be in- and outputs marked with red (right channel) and white (left channel).
I would first try connecting the turntable's leads to the 'Line' input since most later turntables have a small amplifier circuit built in that will take the signal from the pickup, amplify it, and match it to the levels and impedance of the line input on the Denon.
There isn't any danger of making a fatal mistake and you should hear right away if there is excessive distortion or a loudness even when the level is set to a low setting; this implies that the output from the turntable is higher than that input wants to see.

You may need a phono preamp to increase your input voltage coming from the turntable. More information from you would be helpful like what kind of turntable are you using. Whate is your receiver/amp are you plugging into a phone input or a line input? Here's the science part: Typically a line level input is expecting a 2V signal. A Moving Magnet (MM) phono input would expect something in the mV range (e.g. 2 - 4 mV) and a Moving Coil input would expect 1/10th that of the MM input (so 0.2 - 0.4mV or thereabouts). If your receiver has a phonostage then you may have a different problem but this sounds like the phono is not putting out a voltage that the receiver/amp is able to amplify. Search for phono preamps (some are very inexpensive) but find out what type of cartrige your record player uses (MM,MC or crystal) all types have large differences in output signal voltage. Good-luck.

Dear,

I donot think AVR588 is capable of down-converting from HDMI to component, so if you input is only HDMI and output is component, it will not work. ( see page 53 in trouble shooting as also page10 of the manual).
Therefore, you will need to match your input with your output.

If you are not too fussy, the component video signal is probably as good..You will hardly see a difference unless your AVR is capable of up-conversion, still the real difference can really be seen only on HD.
Best is to connect all the analog connections as well and enjoy.
