* An audio adapter (sold separately) may be required to connect the RCA audio cable to the line input jack of the PC
sound card.
When connecting via Bluetooth, using the pre-amplifier selector switch is not necessary.
Connecting the device
Align the settings for the pre-amplifier selector switch and connect the RCA audio cable to an input jack that is
compatible with the connectable equipment you are using (amplifier, receiver, active speakers, sound card, etc.).
The RCA audio cable’s red jack is for the right (R) channel, and the white jack is for the left (L) channel.
