5. hear distortion or clipping If you hear distortion before you reach the 3 4 volume setting of your head unit reduce the gain setting on the amplifier and start to raise the head unit volume again When you can listen to the music at or slightly above 3 4 on your head unit without audible distortion slowly raise the gain of the amplifier until distortion is heard then back off the gain until the distortion is not audible This setting will allow you to reach full output with all but the quietest of source mate rial while avoiding excessive noise in the system m For systems using the Remote Sub Level Adjustment increase the subwoofer gain on the amplifier by 25 and set the Remote Sub Level knob to the center position after making all system gain and filter adjustments This will give the Remote Sub Level Control a wider range of adjustment to the subwoofer output m You should take into consideration the effect that gain adjustment has on system frequency response and staging Again plan on spending some time with music that you know getting the gain and crossover settings the way you like Test discs and analyzers may help with this process but in the end it s your ears that count listen to the music 2005 Directed Electronics Inc all rights reserved LED TUBE INSTALLATION OPTIONAL This Directed Audio amplifier has been designed with a custom heat sink that can accommodate two optional not supplied VARAD LED tubes 1 Bef
