LINE LEVEL INPUTS & OUTPUTS - The most commonly used inputs & outputs 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 from speaker level leads, use the supplied “High Level Adapter” to connect to the amp.

GAIN CONTROL - 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” be it 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.)

HIGH-PASS CROSSOVER CONTROL - If the control 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 CROSSOVER CONTROL - If the control 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.

BASS BOOST - This control provides additional bass in the 45Hz area to give a stronger low end “feel” to the bass. Once switched on, this will also allow the amp to be driven into distortion sooner so the user must be aware.

PROTECTION LED - This light turns on if the amplifier senses a severe problem, such as a speaker short circuit.

POWER ON LED - This light will turn on when the amplifier receives a +12V turn on signal from the radio. If the amp is properly wired, but the light does not turn on, there may be a short circuit condition that the amp is protecting itself from.
