1 Frequency Adj

. 

(NA-8600 only) 

- This pot adjust the frequency 

level sent to your speaker on channel 1 when using your amplifier in 
subwoofer mode.

19. Mode Selection Switch

 - This recessed, three-position switch configures 

the amplifier for Stereo, Parallel or Bridged Mode operation. Amplifiers are 
factory-configured for Stereo Mode. See section on Mode Selection for more 
information.

20. Fuse Holder

 - This holder houses the external fuse. Always replace with the 

exact same type fuse, otherwise instructed to do so by an authorized audio 
service technician.

21. Channel 2 XLR THRU Jack (NA-5600 & NA-8600 only)

 - This Jack is used 

to send a parallel signal from the channel 2 input jack to another device or 
amplifier.

22. Channel 1 XLR THRU Jack

 

(NA-5600 & NA-8600 only) 

- This Jack is used 

to send a parallel signal from the channel 1 input jack to another device or 
amplifier.

23. Channel 2 Output Jack / 5-Way Binding Post

 - Connect to your speaker’s 

input jack. Red is positive signal and Black is negative signal.

24. Channel 1 Output Jack / 5-Way Binding Post

 - Connect to your speaker’s 

input jack. Red is positive signal and Black is negative signal.

25. Ground Lift Switch

 - This switch is used to disconnect the internal ground 

signal from the amplifier chassis ground. This may reduce the buzz that is 
caused from an electrical 50Hz/60Hz cycle. 

26. AC POWER Cord

 - Plug this cable into a standard 110V or 220V wall outlet. 

Be sure that the supplied voltage in your area matches the amplifiers 
required voltage. Never plug your amplifier into a wall outlet that does not 
match the required voltage of your amplifier, serious damage may occur to 
your unit.
