In the following we would like to explain to you how to install a typical sound reinforcement system in passive con-
guration with incorporated stage monitors. The necessary equipment is:
1 PowerMate 600-2
1 Power ampli er for the monitor signal – for i. e. 2x250 watts
2 Hi cabinets – i. e. 12“, 3-way loudspeaker systems
2 Lo cabinets – i. e. 15“ woofers
2 Speaker pole-stands or 2 connection rods
2 Stage monitor speakers systems
4 SPEAKON cables (8m) and 2 SPEAKON cables (2m)
1 LF-cable with a stereo phone plug on one and an XLR-type connector on the other end
Setting up
Place the PowerMate and the external monitor power ampli er in a way that allows their unobstructed
operation and connect the mains cord.
Try to locate the best position for the loudspeaker systems. If possible, the woofers should be placed
on the oor while the Hi cabinets’ most favorable position is above the Lo cabinets. Please keep in mind,
that it is important to have the lower edge of the Hi cabinets approximately at the same height level as
the heads of the audience. Either use the connection rods to mount the Hi cabinets on top of the woofers
or, if this kind of installation is not possible or if your application does not employ woofers, use separate
speaker pole-stands.
Do not place the left and the right speakers further apart than necessary. The less distance there is bet
ween the two speaker “clusters” – the more compact the sound.
According to the above diagram, use the SPEAKON cables to connect the woofers and the monitor
speakers to the PowerMate and the monitor power ampli er respectively. Make sure not to confuse the
channels by accident. Use the short SPEAKON cables to connect the Hi cabinets to the woofer outputs
(parallel connection). The two monitor speakers are connected to either one output of the external power
ampli er. Set the ampli er inputs to parallel or monaural operation. The ampli er’s volume controls provi
de the possibility to adjust the output levels independently.
Try to avoid the positioning of the main loudspeaker systems behind the imaginary line of the
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 have found their seat on the stage, the best
place to install the monitor speakers is up front facing the musicians. Nevertheless, please make sure
that no microphone is directly pointing in the direction of a monitor. You should also be aware of the indi
vidual characteristics of the utilized microphones.
Using the stereo plug-to-XLR-type connector NF-cable, connect the AUX output of the PowerMate with
the external ampli er’s input.
