Yes, it is possible to connect both a PC and a Mac to the Edifier R1700BT speakers. Here are the details: - The R1700BT speakers have two stereo RCA inputs, allowing you to connect two different source devices simultaneously. - You can connect your PC and Mac using these RCA inputs, and switch between the two sources using the wireless remote control or the control buttons on the speakers. What's more, the R1700BT speakers also support Bluetooth connection, meaning you can also connect a device via Bluetooth while having devices connected via the RCA inputs.

If your PC is equipped with Bluetooth, yes.

After receiving it, I can confirm that it is the remote control WITH standby button :)

Thank you for the answer, Jarekfracek. :) Since I would like to use the Bluetooth function, the question for me is whether the Bluetooth pairing is still permanently open once you are in Bluetooth mode (i.e. anyone can connect to the speakers without having to activate the pairing first). Since I live in a multi-party building, it could happen that someone simply connects to the Bluetooth, thereby interrupting my connection or playing something else. That would be a killer criterion for me. Thank you very much.
