4.2 Povezivanje audio izvora

Connect your audio source (e.g., PC, phone, TV, CD player) to the P32 using either the RCA input or the 3.5mm AUX input on the rear panel.

• For RCA connection: Use an RCA cable to connect the audio output of your source device to the RCA IN (L/R) ports.
• For 3.5mm AUX connection: Use a 3.5mm audio cable to connect the audio output of your source device to the AUX IN port.

Važno: Only use one input at a time. Connecting both RCA and 3.5mm AUX inputs simultaneously is not recommended and may cause audio issues.

4.3 Povezivanje slušalica ili zvučnika

• Za slušalice: Plug your headphones into either the 6.35mm or 3.5mm headphone output jack on the front panel. Both outputs can be used simultaneously.
• For Active Speakers/Power Amplifier (Preamp Funkcija): Connect the 3.5mm headphone output on the front panel to the AUX/RCA input of your active speakers or power ampuređaj pomoću odgovarajućeg audio kabela.
