4ch amp PB417X PB617X

dual crossover mode selectors	when used with normal, full range systems, set this switch to “FULL”. If
	you wish the internal crossover to power a driver of specific frequency
	range , use the “LOWPASS” or “HIGHPASS” settings.
dual input level controls	use this control to match the outputs of you head unit to the amplifier.
	Starting with your head unit set at about the 2 o’clock position, increase
	the amp level control until distortion begins to occur, and reduce slightly
	from this point.
CH1/2 low pass frequency control	when the crossover selector switch is in “low pass” mode, this control
	sets the upper frequency limit for audio program sent to the speakers.
dual high pass frequency controls	when the crossover selector switch is in “high pass” mode, this control
	sets the upper frequency limit for audio program sent to the speakers.
CH1/2 bass boost level control	this control permits adjustment of the bass level up to an increase of
	approximately 18 dB.
dual level inputs	this amp features gold-plate RCA input jacks for high impedance input.
	Use these with car stereo output which uses RCA-type connector cables.
	if your car stereo lacks RCA-type output jacks, you may connect speaker
	output leads to these input connectors.
