4. X-OVER

    • 

Full pass x-over switch

       When the switch is in the "

Full

" position, the full range is bypassed.

    • 

Low pass x-over switch

       When the switch is in the "

LPF

" position, frequencies lower than the low pass  

       frequency setting are passed. The frequency can be adjusted between 50Hz  
       and 250Hz.

    • 

High pass x-over switch

       When the switch is in the "

HPF

" position, frequencies higher than the high   

       pass frequency setting are passed.

5. 

Low pass x-over frequency control

     This control is used to select the desired low pass x-over frequency. 
     The frequency can be adjusted between 50Hz and 250Hz.

6. 

Bass BOOST

     The boost can be selected among 0dB, 6dB and 12dB.

7. 

REMOTE

     Controls the subwoofer amplifier gain, from a remote location for ease of    
     adjustment during listening.

     

Warning: 

     Do not connect a level control knob from other manufacturers to the Remote  
     Sub Level Control of any amplifier. Even though the connectors fit properly, the  
     control knob and connector pin positions may be different and the amplifier  
     will be damaged.

8. 

LED

     Will illuminate 

GREEN

 to indicate the amplifier is on and operating normally,  

     and will be illuminate 

RED

 if the amplifier shuts down due to short circuit, DC  

     offset, or overheating detected by on board protection circuitry.

9. 

Auxiliary outputs

     The Auxiliary outputs offer LANZAR amplifiers easy, unlimited system expansion.  
     Route RCA's from the line out of the first amplifier to the line input of a second
     amplifier when using a single source output.
