REAR PANEL
1. REAR RCA INPUTS -for rear left and rear right channel
2. LOW PASS FREQUENCY RANGE SWITCH (REAR) -switches the rear low pass
frequency range from 50-500Hz to 500-5000Hz.
3. HIGH PASS FREQUENCY RANGE SWITCH (REAR) -switches the rear high
pass frequency range from 50-500Hz to 500-5000Hz.
4. PROTECT LED -the LED will turn red if the amplifier is in safety mode.
5. POWER LED -the LED will turn green if the amplifier is in use.
6. HIGH PASS FREQUENCY RANGE SWITCH (FRONT) -switches the front high
pass frequency range from 50-500Hz to 500-5000Hz.
7. LOW PASS FREQUENCY RANGE SWITCH (FRONT) -switches the front low
pass frequency range from 50-500Hz to 500-5000Hz.
8. FRONT RCA INPUTS -for front left and front right channel
9. LEVEL CONTROLLER (REAR) —allows adjustment of amplifier to match the
incoming audio level so it can be adjusted for either low level or high level
input.
10. HPF FREQUENCY CONTROLLER (REAR) -controls the high pass frequency
of the rear channels between 20Hz and 4000Hz. Applicable only if the
Crossover switch is in LPF position.

11. LPF FREQUENCY CONTROLLER (REAR) -controls the low pass frequency of
the rear channels between 50Hz and 5000Hz. Applicable only if the
Crossover switch is in LPF position.
12. CROSSOVER SWITCH (REAR) -switches the rear channels in full range, low
pass or high pass mode.
13. INPUT SELECTOR:
4CH :4-channel input (FL/FR/RL/RR)
Bridged :2-channel input for dual mono mode (FL/RL)
ST :2-channel input for 4-channel or 3-channel mode (FL/FR)
14. CROSSOVER SWITCH (FRONT) -switches the front channels in full range,
low pass or high pass mode.
15. LPF FREQUENCY CONTROLLER (FRONT) -controls the low pass frequency
of the front channels between 50Hz and 5000Hz. Applicable only if the
Crossover switch is in LPF position.
16. HPF FREQUENCY CONTROLLER (FRONT) -controls the high pass frequency
of the front channels between 20Hz and 4000Hz. Applicable only if the
Crossover switch is in LPF position.
17. LEVEL CONTROLLER (FRONT) - allows adjustment of amplifier to match
the incoming audio level so it can be adjusted for either low level or high
level input.
This amplifier can operate in two, three or four channel mode. The minimum
impedance for stereo operation is 2 ohms per channel. The minimum
impedance for bridged operation is 4 ohms.
Connect right and left speaker wire to corresponding speaker output
terminals of the amplifier.
Be sure to have the positive wire from the speaker connected to the positive
speaker terminal of the amplifier.
Reversing any of these connections will result the speaker cones moving out
of phase which causes bass cancellation.
