through RCA jacks can be used to
send the input signal to a second
amplifier.
3. RRCCAA IInnppuutt JJaacckkss -- Accepts line level
outputs from head units or signal
processors at voltages between
150mV and 8 volts.
4. IInnppuutt GGaaiinn AAddjjuussttm meenntt -- Controls
amplifier sensitivity and is used to
match the input level of the ampli-
fier to the output level of the signal
source.
5. CCrroossssoovveerr SSeelleeccttiioonn SSw wiittcchh --

not attenuate any frequencies and
is for full-range speaker systems.
HPF attenuates low frequencies and
is used for mid-range speakers and
tweeters. LPF attenuates high
frequencies and is used for
subwoofers speakers.
6. BBaassss EEQQ SSw wiittcchh - Adds an additional
8 db of boost to the speaker output
