Directed Electronics Inc CROSSOVER SETTINGS AND GAIN ADJUSTMENT Your Directed Audio power amplifier needs to be adjusted carefully to achieve maximum performance These are some guidelines to follow when fine tuning the amplifier For ful range and simultaneous stereo mono bass applications the crossover selec tion switch should be set to FLAT If the amplifier is driving your subwoofers set the switch to LPF and for mid bass midrange output set to HPF The crossover frequency control needs to be adjusted to suit your particular system For subwoofer applications try and keep the setting low enough to prevent image smearing you should not be able to hear male voices from the subwoofer but not so low as to create a gap between the subwoofer and the mid bass midrange speakers For mid bass midrange settings try to keep the setting low enough to keep your sound stage in front of you without overdriving the speaker It will be to your advan tage to spend some extra time with this adjustment listening to familiar music or system set up discs to achieve the kind of musical reproduction that you prefer The gain adjustment allows you to set proper signal match for clean quiet amplifier operation For full range and simultaneous stereo mono bass applications start by playing some music you are familiar with With the gain adjustment on the amplifier in the middle of its rotation bring up the volume on your head unit to the 3 4 volume
