Unless you are using a condenser microphone for MIC 2 or MIC 3, ensure that the 
MIC 2 and MIC 3 +48V PHANTOM POWER switches are not depressed. If either 
microphone is a condenser type, depress the appropriate PHANTOM POWER 
switch. 
Warning! Applying phantom power to a non-condenser microphone can damage 
or destroy the mic. 

8.

 

Connect the output of your alarm trigger source to the EMC INPUT terminals on 
the amplifier. 

9.

 

Connect a two-conductor speaker wire (not included) to the input terminals of 
your speaker array. 
Note: The speaker array can be one or more low impedance speakers connected 
in such a way as to present a load between 4 and 16 ohms to the amplifier. 
Alternatively, the array can be one or more 70V or 100V constant voltage 
speakers connected in parallel with a total wattage rating of 48 (18803), 96 
(14886), or 192 (18805) watts or less. 

10.

 

Connect the negative speaker wire lead to the COM terminal on the amplifier. 

11.

 

If using a low impedance speaker array, connect the positive speaker wire lead 
to the 4-16Ω terminal on the amplifier. If using a 70V constant voltage speaker 
array, connect the positive speaker wire lead to the 70V terminal on the 
amplifier. If using a 100V constant voltage speaker array, connect the positive 
speaker wire lead to the 100V terminal on the amplifier. Use only one of these 
options. 

12.

 

Flip the terminal cover back over the speaker output terminals to protect from 
electric shock due to accidental contact. 

13.

 

(Optional) If you want to send the mixed signal to another amplifier or other 
device, plug one end of a stereo RCA cable (not included) into the stereo input 
on your other device, then plug the other end into the MIX OUT RCA jacks on 
the amplifier. 

14.

 

Ensure that the ON / OFF power switch on the front panel is in the OFF position. 

15.

 

Plug the included AC power cable into the C14 AC INPUT on the amplifier, then 
plug the other end into a nearby AC power outlet.
