Re: on jvc tdw11
The line out of a tape deck is about 1 volt peak, the output of a turntable is about 3-5mV on average.
Not sure what issue you are having but the turntable cannot be directly plugged into the cassette deck for recording LP to cassette. it would have to go through the receiver.

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
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.)
1) the JX-S900 needs to be a proper matrix switcher. It has to have the ability to route 1 input to more than one output.
2) the sub signals need to be low level RCA/phono, and not high level speaker wire connections. That's not just about the type of connector. It's about the signal going through those wires. A low level RCA/phono sub connection conducts a maximum 0.7 Volt. A speaker wire connection can transmit 30 Volts! If you put 30 Volts in to a line level switching device such as the JX0S900 you'll fry it.
Provided that the above two criteriia are both met, then yes it will work.
Connect the AV receiver's sub out to Source 1 - white RCA phono.
Connect the two subs mono LFE Left input (white RCA) or the single black RCA/phono inputs to the JVC's outputs 1 and 2 - white RCA/phono.
Set the source routing: input 1 goes to output 1 and 2
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.
if there is no phono input,you need a pre amp to drive it.the record player puts out 5 mv from the cartridge.
a cd player is 800 mv to one volt output.
the turntable can not drive the cd input.
a phono pre amp also has a 60db gain from 20hz to 1khz to offset the -60 db curve when records are made to reduce the groove modulation.
without the bass attenuation,record grooves would have to swing 4" for bass notes.
google RIAA equalization curve for a description.
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.
Yes, this output on this receiver is at line level, (.775 MV) Or better known as 0 db level. You will need a powered subwoofer to get the bass to work. If you need an owners manual, you can get one here: http://books.jvcservice.com/download/256239653/17839.pdf Good Luck
