5. Inställning

5.1 Anslutning av strömförsörjning

Connect a DC power adapter (18V-36V, above 10A recommended) to the DC socket. Ensure the polarity is correct if wiring directly. The amplifier requires a minimum of 18V to function.

Image: A warning graphic emphasizing that the amplifier requires an input voltage of ABOVE 18V to operate correctly. This is a critical setup requirement.

5.2 Högtalaranslutning

Connect your speakers to the appropriate terminals:

• Left and Right Channel Speakers: Connect 3-8Ω full-range speakers with a power rating of 20W-300W.
• subwoofer: Connect a 2-8Ω subwoofer with a power rating of 50W-350W. For optimal performance, a subwoofer with a frequency range of 20Hz-200Hz is recommended.

Note on Impedance: If connecting multiple speakers in parallel, ensure the combined impedance for the left and right channels remains above 3Ω, and for the subwoofer, above 2Ω. Incorrect impedance can trigger overcurrent protection.

5.3 Ljudingångsanslutning
