. See below illustration: EN 9 Adjust input level To ensure sound quality, adjust input level to match it with the car audio’s output voltage. 1 Check the line output voltage of the connected car audio. 2 Rotate INPUT LEVEL to select a matched voltage: 0.3V to 6V. Adjust bass boost To enjoy more bass sound: 1 Set FILTER MODE at OFF or LPF mode. 2 Slide BASS BOOST to 12dB position. Tip •• If BASS BOOST is set at 0dB position, no extra bass will be boosted. Note •• If FILTER MODE is set at HPF mod
