. 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 mode, the bass frequency will be filtered. About the protector indicator The amplifier has a built-in protection circuit to protect the transistors and speakers in following conditions: • The amplifier is overheated. • A DC current is generated in speakers. • The battery voltage is too low or too high. Or • The speaker terminals are short circuited. When the PROTECTED indicator lights up in red, the amplifier shuts down automatically. In this case please: 4 Use your power amplifier Select filter mode Select Filter Mode according to the connected speaker type. 1 Slide FILTER MODE to the selected position. • HPF (high-pass-filter): Select this mode when mid-range speakers and tweeters are connected for high frequency output. • LPF (low-pass-filter): Select this mode when woofer and subwoofer are connected for low frequency output. • OFF (flat): Select this mode when both tweeters and woofers are connected. Select LPF frequency When FILTER MODE is set at LPF position, you can select the range of frequency that is to be filtered. Note ••When FILTER MODE is set at OFF or HPF position, LPF FREQUENCY does not work. 1 Slide LPF FREQUENCY to the selected position. • 80Hz: More high frequency signal is filtered. Select 80Hz if you prefer stronger bass effect. • 180Hz: Less high frequency signal is filtered.

Replace fuse If there is no power, the fuse might be damaged and need to be replaced. 1 Pull out the damaged fuse. 2 Replace the fuse with the supplied fuse or buy a new fuse that matches the rating of the damaged fuse (30A x 1). If the fuse gets damaged immediately after it has been replaced, the amplifier might have internal malfunction. Consult qualified personal for repair. EN 11 6 Troubleshooting To keep the warranty valid, never try to repair the system yourself. If you encounter problems when using this apparatus, check the following points before requesting service. If the problem remains unsolved, go to the Philips web site (When you contact Philips, ensure that the apparatus is nearby and the model number and serial number are available. Power indicator does not light up The connected car audio •• is not turned on. •• The fuse is blown. Replace the fuse with a new one. •• The input level is not set correctly (see “Adjust input level”). The protector indicator lights up in red. •• The speaker terminals are short circuited. Check the speaker connections. The sound is too low. •• The input level is not set correctly (see “Adjust input level”). The sound is interrupted or stopped suddenly. •• The thermal protector is activated. Reduce the volume. •• The ventilation outlet is blocked. Remove any obstructions from the outlet. Alternate noise is heard. •• The power connecting wires are installed too close to the RCA pin cords. •• The ground wire is not securely connected to a metal point of the car. •• Negative speaker wires touch the car chassis. The unit becomes abnormally hot. •• Place the amplifier in a well ventilated location. •• Use speakers with suitable impedance: 2-8 ohm (stereo), 4-8 ohm (bridged).
