What’s more:
- Please do not use the BACKUP tube(with a letter “B”) when you start the device for the first time.
- 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 T7.
- Please keep T7 away from devices that can transfer signal like cellphones and routers.
- Do not connect T7 to any inferior Bluetooth digital amplifiers except Class T digital amplifiers, since all Class D amplifiers have very loud background noise.
