1. QUICK START - PASSIVE SPEAKER CABINET
Make all initial connections with all the equipment powered off, and ensure that all the main volume controls are turned completely
down.
-. For Passive Full-range Speakers
1). Connect one side of the speaker cable to the Output CHA/CHB or Binding Post of your stereo power amplifier
and the other side to the Input socket of your speaker cabinet.
2). Complete other connections as illustrated.
3). Turn on your mixer first, then the stereo power amplifier.
4). Turn up the volume controls of your amplifier to about 70%.
5). Use PFL function to get the proper input level for the mixer, and adjust the Main Mix Level control to manipulate the output
level.
6). After using, turn off your stereo power amplifier first, then the mixer.

4. WIRE CONNECTIONS
-. For Passive Speaker Cabinets
Please use only the power connectors to make connections with other signal source equipment for the passive speaker
cabinets. The power connector has four terminals: 1+, 1-, 2+, 2-.
1+
2-
In our cabinets, only 1+/1- are used to connect the Speaker+/Speaker-, and 2+/2- are not used.
-. For Active Speaker Cabinets
As to these circumstances, audio connections is mostly intended for the signal flow, so, determine the wire configuration
according to your real application system and its connecting facility. Normally, you have the following choices:
