4. POWER INDICATOR

     This indicator lights up when the internal switching power supply is activated
     and the unit is operational.

5. LEFT/RIGHT HIGH IMPEDANCE INPUT

     To be connected to output of source unit.

6. LEFT/RIGHIT LOW IMPEDANCE INPUT

     If RCA output is not available, connect speaker outputs of signal source to this
     input.

7. HIGH-PASS FREQUENCY SELECTOR

     For selection of high-pass crossover frequency between All Pass, 80Hz, 100Hz  
     and 125Hz.

8. HIGH-PASS FILTER SLOPE SELECTOR

     

6 dB: 

When the high pass crossover frequency is set close to the speaker's

     resonant frequency, where the response rolls off at a rate of 12 dB per octave,  
     switching the selector to the “

6 dB

” position would produce the ideal 18 dB    

     odd order type phase response.

     

18 dB: 

When the crossover frequency is set away from the speaker's resonant

     frequency, switch the selector to the “

18 dB

” position for ideal 18 dB odd order  

     type phase response.

9. HIGH-PASS OUTPUT LEVEL CONTROL

     For adjusting the high-pass output signal level.

10. LEFT/RIGHT HIGH-PASS OUTPUT TERMINALS

        To be connected to the mid/tweeter amplifier left/right inputs.

11. LOW-PASS FREQUENCY SELECTOR

        For selection of the low-pass crossover frequency between 50 Hz, 63 Hz,    
        80Hz and 100 Hz.

12. LOW-PASS OUTPUT LEVEL CONTROL

        For adjusting the low-pass output signal level.

13. LEFT/RIGHT LOW-PASS OUTPUT TERMINALS

        To be connected to the woofer/subwoofer amplifier left/right inputs.
