Record Player

High everyone. My fantastic wife got me my first record player as a gift, but I need a little help. I have a receiver that I am attempting to connect it to via rca, but when I use the phono input on the receiver it sounds awful, staticy, super loud and too much bass. If I use a different stereo input it sounds clean and normal, but there is absolutely no bass. I suspect that part of the issue is that it may have a built in preamp. Any help would be great. The receiver is a pioneer vsx-lx303. I posted this in receivers as well, because I'm not sure where the issue is. Thanks.

Are those two round objects on your TT built in speakers??

What you have doesn't have a line output or output for a phono input. The outputs are for connection to a PC or to external speakers, presumably using the internal amplifier that your record player has. That is why it doesn't sound right into a line level input on your receiver. If your receiver has a Bluetooth input, then you could use that method, but I haven't checked your receiver to know.

System
Spoiler!

It sounds LOUD and TOO MUCH BASS when plugged into PHONO Input because your Turntable has a CERAMIC PHONO CARTRIDGE, which provides standard "LINE LEVEL"...and doesn't NEED a Preamp or any additional RIAA Equalization....which is MOSTLY cutting the Mid and High Freqs:
http://sound.whsites.net/project06.htm

Specs confirm this....yup it's a CERAMIC PHONO CARTRIDGE with Output Voltage = 300 mV [approx. LINE LEVEL], shown in picture driving a set of POWERED Speakers (e.g. typical PC Speakers)...which is also compatible with Pioneer's 4 ea LINE LEVEL Inputs:
[PS: I think they made a typo...should read "LINE IN = 500 mV".]

https://www.google.com/imgres?imgurl...act=mrc&uact=8

Since your Turntable has a LINE LEVEL Output, you should plug the Turntable's RCA Jacks directly into one of the adjacent "AUDIO IN" RCA L/R Inputs....your choice which one.
https://www.pioneerelectronics.com/e...180418_web.pdf

If you provide the mfr and model number of your Ceramic Phono Cartridge, we can direct you to specs and where you can buy a replacement STYLUS (aka Needle)....which likely needs to be changed....

Ceramic Cartridges typically track at MUCH higher weights [typ. 4-6g] than modern MM or MC Cartridges [typ. 1-2g], which is one reason they have a bad reputation of SHREDDING pricey Vinyl Records [also shape of the Diamond]....but you'll have to investigate whether your Turntable can be adjusted down to as low as 1-2g of tracking force if you decide to "upgrade" the entire Phono Cartridge. Pioneer VSX-LX303 has a "PHONO" Input which will accept low-level signals from a MM (Moving Magnet) type Cartridge. [I did not readily find Instructions for the Japostar TT.....nor did I research as to WHICH Ceramic Replacement Cartridge MIGHT be any "better".]

And as explained on pg51 in the Manual, you would need to use some sort of "Equalizer" [e.g. MC-MM Transformer] if you are using a MC (Moving Coil) type Cartridge:

Thank you so much for the information! I really appreciate it, as I was having some trouble finding information. You are awesome!

These are the cartridges they offer as replacements. If I understand correctly, I would not be able to change it to a magnetic (which sounds better) cartridge, right?

If it is not too late to return the turntable to the dealer, I suggest obtaining a normal hi-fi unit. That is, a turntable that utilizes a magnetic (moving-magnet, also called "MM") phono cartridge and has outputs intended to be connected to a hi-fi component, such as your receiver. You can then use your Pioneer's phono inputs. You do not need to purchase a turntable that has its own built-in phono preamp because the Pioneer already includes one, as you know.
