1. RCA Line Output Jacks
Full range output from channel L + R inputs is provided at Line Out Jacks
2. RCA Low Level Input Jacks
It allows left and right inputs to be connected to the amplifier using RCA plugs.
3. Input Level Control
It allows for the adjustment of the gain of both channels to match the output level of the source.
4. High Variable Controls
Adjust the crossover frequency of the High Pass output only, from 75Hz to 750Hz.
5. Low Variable Controls
Adjust the crossover frequency of the LOW pass output only, from 40Hz to 150Hz.
6. Bass Boost Controls
Adjust the sub boost level of the selected frequency output from 0dB to + 18dB.
7. X-over switch
a) Low position: Allows for the control of the low pass frequency range (40Hz-150Hz) by
using the Low Variable.
b) Flat position: Allows for full range pass through.
c) High position: Allows for the control of the high pass frequency range (75Hz-750Hz) by
using the High Variable.
8. Subsonic Filter
It allows to delete the frequency under 35Hz for Subwoofer protection.
9. Power & Protection indicator
It has two color indicator and the Green indicator indicates amplifier has turn on signal. The Red
indicator indicates the fault operation of the amplifier. When the fault conditions (overload,
excessive heat or short circuit of speaker) arise, the protection circuit is engaged to protect both
the speakers and amplifier against damage.
10. Fuse
It protects both the amplifier and automobile electrical system from fault conditions. Use a
standard automotive fuse, 300.S:30A, 400.S:40A, 500.S:40Ax2.
11. Power connection
Co12VDC power wire from the battery and also connects ground wire from a suitable
ground point on the chassis.
12. Remote connection
Connects the control wire which allows the amplifier to be turned on and off by the radio cassette
player.
13. Speaker Terminal
It allows the connection of speakers to the amplifier.
