In this chapter we would like to explain to you how to install a typical sound reinforcement system in passive
configuration and incorporating stage monitor speakers. The necessary equipment is:
1PowerMate 1000
1Power amplifier for the monitor signal – for i. e. 2x250 watts
2HI cabinets – i. e. 3-way 12" speakers
2LO cabinets – i. e. 15" woofer
2Speaker pole-stands or 2 connection rods
2Stage monitor speakers
4SPEAKON cables (8m), and 2 SPEAKON cables (2m)
1Balanced LF-cable with a stereo phone plug on one side and an XLR-type connector on the other side
Setting up
•Place the PowerMate and the external power amplifier in a way that allows their unobstructed operation during
the sound check and the later performance.
•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 as the heads
of the audience. Either you use the interconnection rods to mount the Hi cabinets on top of the woofers or, in
case this kind of installation is not possible in your application, you have to use the separate speaker pole-stands.
•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 artist found a seat on the stage, the best place to install
the monitor speakers is up front facing the musicians. 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 used microphones.
•Make all connections according to the diagram above. Use the different SPEAKON cables to connect the speaker
systems to the PowerMate’s power outputs, respectively to the power outputs of the external amplifier. Make
sure not to confuse the channels by accident. using the short SPEAKON cables, you can connect the Hi cabinets
at the woofers’ outputs. The two monitor speakers are connected to either one output of the additional external
amplifier. The amplifier should be set to coupled operation, so that the inputs are configured to accept a monaural
audio signal. The amplifier’s volume controls provide the possibility to adjust the output levels separately.
