SETTING UP A STANDARD PA-SYSTEM
In the following we would like to explain how to install a typical sound reinforcement system in passive configuration. The necessary equipment is:
1 PowerMate 1000
1 Power amplifier, e.g. 2x250 watts
2 HI cabinets, e.g.
2 LO cabinets, e.g. 15” woofer
2 Speaker
2 Stage monitor speakers
4 SPEAKON cables 8m, 2 SPEAKON cables 2m

Place the PowerMate and the external power amplifier in a way that allows their unobstructed operation and connect the mains cord.
Try to locate the best position where you want to place the loudspeaker systems. If possible, the woofers should be placed on the floor while the Hi cabinets’ most favorable position is above the Lo cabinets, on the same vertical axis. It is important that the lower edge of the Hi cabinets is approximately at the same height level or slightly higher as the heads of the audience. Either you use the interconnection rods to mount the Hi cabinets on top of the woofer cabinets or, in case this kind of installation is not possible or you are not using woofer systems, use the separate speaker
Do not place the left and the right speakers further apart than necessary. The less distance there is between the two speaker “clusters” – the more compact the sound.
Try to avoid the positioning of the main loudspeakers behind the imaginary line of microphones. Otherwise, if you have to drive the system at higher sound levels, the risk of feedback is very likely. After you have installed all microphone stands and all artists found their place, the best spot to install the monitor speakers is up front facing the musicians and vocalists. Nevertheless, please check if a microphone is directly pointing in the direction of a monitor. In this case, change its position. You should also be aware of the individual characteristics of the employed microphones.
Establish connections according to the diagram. Use the different SPEAKON cables to connect the speaker systems to the PowerMate’s power outputs, respectively to the power outputs of an external amplifier. Make sure not to confuse the channels by accident. Using the short SPEAKON cables to connect Hi and Lo cabinets in parallel. The two monitor speakers are connected to the outputs of the monitor power amp.
