NA-3600/NA-5600/NA-8600 FRONT PANEL

1. Rack Mounting Ears - Two front panel mounting holes are provided on each

mounting ear.

2. Fan Inlet Grills and Filter - NA Series amplifiers are cooled by two rear-

mounted fans. Cool air from front grills is filtered and flows over the heatsinks
and exhausts to back side. Make sure these outlets remain clear to allow
unrestricted air flow.

3. UNiKA Logo and Model No - NA series have 3 types of 2U models NA-3600

/ NA-5600 / NA-8600.

4. Signal Indicators - These green and yellow LED’s will glow according to the

average signal output.

5. Clip LED - Illuminates at the clipping threshold. Continuous illumination also

indicates that ACL (Active Clip Limiting) protection circuitry is engaged.

6. Protect Indicator - The red Protect LED will begin to glow when the channel

goes into protect mode. When the channel goes into protect mode all output
for that channel will turn off. This is to protect any speakers connected to the
channel.

7. Power Indicator - This blue LED will glow when mains power is applied to

the unit. This light may continue to glow briefly after mains power has been
turned off, this is normal.

8. Input Attenuators - Two input attenuators adjust level for their respective

amplifier channels.

9. Limiter Switch - You can select limiter "ON" for limiter working, or turn “OFF”

the limiter.

10. AC Power Switch - MP Series amplifiers have a front-panel AC mains

power switch.

11. Fan Outlet Ports - Cooling air enters the amplifier through the front grills

and exhausts through the fans. Be sure not to block these ports when
installing the amplifier or other associated equipment. Air must flow
unimpeded through these ports.

12. Channel 2 Frequency Adj. (NA-8600 only) - This pot adjust the frequency

level sent to your speaker on channel 2 when using your amplifier in
subwoofer mode.

13. Channel 2 Subwoofer Mode On/Off Switch (NA-8600 only)- Turns the

subwoofer mode for channel two on and off.

14. Channel 2 Balanced 1/4" TRS & XLR Input Connectors - These

connectors accept input signals on balanced TRS and XLR input plugs. See
the figure 3 for information on polarity. Connectors for each channel are in
parallel; the unused connectors may be used for "loop through" connection
to other amplifiers.
XLR pin setting: Pin-3/signal Negative, Pin-2/signal Positive, Pin-1/Ground.

15. Low Cut Filter Mode Switches (NA-5600 & NA-8600 only) - These DIP

switches are used to activate and adjust the built-in Low Cut Filter, see ”Low
Cut Filter” on Page 13.

16. Channel 1 Balanced 1/4" TRS & XLR Input Connectors - These

connectors accept input signals on balanced TRS and XLR input plugs. See
the figure 3 for information on polarity. Connectors for each channel are in
parallel; the unused connectors may be used for "loop through" connection
to other amplifiers.
XLR pin setting: Pin-3/signal Negative, Pin-2/signal Positive, Pin-1/Ground.

17. Channel 1 Subwoofer Mode On/Off Switch (NA-8600 only)- Turns the

subwoofer mode for channel one on and off.

NA-3600 REAR PANEL

NOTE : Unbalanced "Tip / Sleeve" plugs
may be used with the balanced TRS " Tip /
Ring / Sleeve " connectors. The "ring"
terminal or negative input will be connected
to ground internally. When using three-pole
(stereo) TRS connectors, make sure that
the ring connection is made either to the
cold (-) output of the source equipment, or
to ground. Incorrect connections may
cause a 6dB loss in level.
