3. LOW INPUT (RCA) Jacks
These RCA style input jacks are for use with source units that have RCA line level outputs. A source unit
with a minimum output of 500mV is required for proper operation. However, this input can accept levels up
to 4Vrms.
4. GAIN Control
This control is used to match the sensitivity of the amplifier to the particular source unit (radio) that you are
using up to 4 volts. Please note the GAIN control is not a volume control, it is a level match.
5. LPF (Low Pass Filter) Control
This filter allows low pass of frequency and is adjustable from 40Hz to 250Hz. A setting of 40Hz will produce
only low frequencies (deep bass). A setting of 250Hz will allow the amplifier to produce a more punchy
(higher) bass response.
6. BASS EQ Control
This equalization circuit is used to enhance the low frequency response of the vehicles interior. With up to
18dB of boost centered at 45Hz the Bass EQ can be adjusted to meet your own personal taste. Please note
– by boosting the Bass EQ to its full +18dB you are asking the amplifier to work 10 times harder!
7. STATUS Indicator
This RED L.E.D. glows only when the built-in protection circuitry is activated. This indicates a problem with
the system in relation to the amplifier and/or wiring (see Troubleshooting Tips).
8. POWER Indicator
This GREEN L.E.D. lights up when the power is on and the system is wired correctly.
9. POWER PLUG-IN Connector
This 6-pin Molex style connector is where the wiring harness plugs in for the
power
(+12V),
ground
(GND)
and
remote turn-on
(REM) wires.
10. FUSE 20A
For convenience the amplifier uses a common automotive ATC type fuse. For continued protection in the
event a fuse blows, replace only with 20 Amp (Yellow ATC) fuse. Substitution or deletion of the fuse will void
the product warranty and may cause damage to your car or the amplifier.
CAUTION:
The power fuse on the amplifier chassis is to protect the amp against overdrive. To protect the
vehicles electrical system, an additional fuse must be used within 18-inches of the battery on the +12V
cable.
