Example 3: Two Trouper loudspeaker systems with remote mixer, DJ controller, etc.: 
 
 
 
 
Connect a dynamic microphone to the Ch. 1 
Input using an XLR or 1/4" (6.35 mm) TRS 
cable. Connect a guitar with an active pickup 
to the Ch. 2 Input using a 1/4" (6.35 mm) TS 
cable. 
Note: When using the Trouper loudspeaker 
system with a guitar, we recommend using 
one with active pickups rather than passive 
pickups. If you use a guitar with passive 
pickups, connect it to an external preamp or 
direct input (DI) box, and connect the line-
level output to the loudspeaker. 
We recommend using dynamic microphones 
with the Trouper loudspeaker rather than 
condenser microphones. If you use a 
microphone that requires +48V of phantom 
power, you must connect it to an external 
phantom power supply. Trouper does not 
supply any phantom power.

Connect the left and right output of your DJ 
mixer, controller, etc. to Ch. 1 Input of each 
loudspeaker system using XLR or 1/4" (6.35 
mm) TRS cables. 
Tip: To send the same mix to both Trouper 
loudspeakers, connect both channels of your 
DJ mixer, controller, etc. to the Ch. 1 and Ch. 
2 Inputs of one loudspeaker, and then connect 
that loudspeaker's Link Output to the Ch. 1 
Input of the other loudspeaker. Both Trouper 
loudspeaker systems will then play identical 
summed mono mixes.
