What's more:
It will be better if its GND jack can be really connected to the ground, which can decrease the background noise to a very low level.
For MM turntables, please check whether your MM cartridge is the old version. If so. we suggest you to upgrade it as a new version one will bring much better sound.
Please make sure that your turntable has a PHONO output. A LINE OUT turntable has a built-in preamp and it won't work well with T12
Please keep T12 away from devices that can transfer signal like cellphones and routers.
Turntable GND cable must be connect to T12's GND jack.
If your MC cart is low impedance and with low voltage output. The sound may will not very loud.T12 best work with the MC cart which is impedance >=100 ohm
