5. NTROL The gain control allows for a range of 0 3 6Volts input This means that if the setting is a 0 3V it only takes 0 3Volts to drive the amp to full output Such a low setting allows for the amp to be easily overdriven and more susceptible to noise so a mid position is highly recommended for most radios CROSSOVER MODE SELECTOR Depending upon the system design chosen you need to set the amplifier in the proper mode LP Flat or HP The low pass and high pass frequency settings are explained below The Flat setting simply allows for the amp to pass all audio frequencies without any kind of crossover filter application This is common with 6x9 fullrange coaxial speakers for example CROSSOVER CONTROL HIGH PASS If the Mode Selector is in the HP position the amplifier passes only mid and high frequency sound The lower limit for such sound is set via this control A common setting is just above 100Hz LOW PASS If the Mode Selector is in the LP position the amplifier passes only low frequency sound The upper limit for such sound is set via this control For bass a value just below 100Hz is usually best LINE LEVEL INPUTS The most commonly used inputs in the aftermarket are RCA type line level inputs These can handle up to about 6 Volts rms without overdriving the amplifier Such high voltages are rarely found from car audio head units so this is a very comfortable value But should the use need to drive the amp directly f
