Please note as a phono preamp, it can only work with MM turntables. Please note your turntable should have no built-in phono preamp. If it has, please make sure there is a PHONO OUT/LINE OUT switch and you should put it on PHONO OUT position. We do not recommend using it with class D amplifiers since most class D amplifiers have much noise. Parameters: 1.

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 keep T7 away from devices that can transfer signal like cellphones and routers.
