12. AC INPUT: Grounded AC power input and fuse holder.
13. OUTPUT: Speaker output terminals for 70V, 100V, and low impedance 4~16 ohm
speaker loads.
14. EMC INPUT: When a signal is detected on this input, all inputs except MIC 1 are
muted, allowing for clear broadcast of important messages.
15. MUTE: This knob controls the amount of automatic volume reduction that is
applied to all inputs except MIC 1 whenever a signal is detected on the MIC 1.
Unlike the total muting when an EMC trigger is detected, this only reduces the
volume of the other inputs, allowing you to talk over the other audio content.
The amount of signal reduction is from 0dB to 30dB.
16. MIC 2 / MIC 3: Unbalanced stereo 1/4" TRS microphone inputs.
17. MIC 2 / MIC 3 LINE INPUT: Unbalanced stereo RCA microphone/line level inputs.
18. AUX 1 INPUT / AUX 2 INPUT: Stereo line level RCA auxiliary inputs.
19. MIX OUT: Stereo line level RCA output of the final mix.
20. FAN: The cooling fan automatically turns on when the temperature reaches
+131°F (+55°C).
21. MIC 2 XLR GAIN / MIC 3 XLR GAIN: Use these knobs to control the amount of
gain applied to each of the two XLR microphone inputs.
22. MIC 2 +48V PHANTOM POWER / MIC 3 +48V PHANTOM POWER: Depress these
buttons to apply +48V phantom power to the respective XLR microphone input.
23. MIC 2 / MIC 3: Balanced mono XLR microphone inputs.
