Question about TechniSat Digitradio 143 V3

You can connect the device to your Yamaha RX V4A receiver by routing the output signals from the device to the receiver via RCA or optical cables. There is no direct Bluetooth connection from the device to the receiver as the device can only receive Bluetooth input signals.

To integrate your record player, you can connect it to the device via the AUX input (3.5 mm stereo jack), provided the record player has a built-in phono preamplifier or an external preamplifier. You can then forward the output signals to the receiver via the cables mentioned above.
