Turntable volume very low

[Runnerbean]

Hi All,
Wondering if you can help.

Apologies if this help request is in the wrong section of the forum.

When I use the turntable, the volume is very low compared to the cd player. I understand it could be the cartridge or the amp but both seem adequate so I'm not sure what the problem could be.

The kit is:
Pioneer A300R precision amplifier. Received today - very nice
Thorens TD166 MKII turntable with a Goldring Elektra cartridge. Output is 5mv
JR 149 speakers
A cheap/nasty sony cd player

Any help much appreciated

Apologies if this is too obvious, but:

Turntable connections into "phono input" (not a line input!)?
Amplifier switching all in the correct places / line up?
Can you try an alternative TT / cartridge?
Possible fault with phono stage (How old is the amp; where / when did you obtain it)?
Do you have the amplifier manual to 'troubleshoot'?

Hello Christopher, I looked up the spec of your amplifier, and is is as below

Input Sensitivity Impedance
PHONO(MM) 2.8mV/50kOhm
CD, Tuner, Line, Tape 1/DAT, Tape 2 Monitor 200mV/50kOhm

Phono Overload Level
1kHz THD0.1% (MM) 150mV

Have you checked you have the turntable lead plugged into the phono RCA sockets on the amp? You should not have a volume issue IMO.

Can you check if the turntable and cartridge work with another amp OK? If it does and you have the turntable connected to the phono sockets on the Pioneer A300R then it sounds as if you might have a phon stage problem. To check this connect another turntable with a MM cartridge and see if it works or not.

I hope that helps.

This is a typical problem in that you are putting 10x the necessary signal level into the CD input.

Input Sensitivity Impedance
CD, 200mV/50kOhm

Typical CD player output 2V, or to put another way 2000mV.
The only way to equalise the levels is to cut down the CD output signal, a few players have adjustable output, or you could use attenuators.

The problem is attenuators often rob the dynamics of the signal.

Hi Gordon, Thanks for your reply. Using the phono input and the amplifier switches are all in the right places. I brought the amplifier a couple days ago from a fellow forum member who only used it for CDs. So it could be the phono

I think I need to check the amp with another turntable and the turntable with another amp. I can't do this at home but I might take it to the shop I brought he speakers from.

Hi Alan, Thank you for replying. I'm not very technical (!) but the volume on the CD seems about right, volume turned a quarter up is a nice healthy volume, whilst the same volume on the turntable and I can barely hear. Sorry for the non technical reply

Good plan.... Should present you with an answer I suspect.

the amp may have been modded i guess.. ive heard of some that the phono stage is removed and its just a line..

Exactly what I thought, it's a fairly common issue.
