Dynacord POWERMATE 1000 Owner's Manual page 51

In the following we would like to explain how to install a typical sound reinforcement system in passive
confi guration. The necessary equipment is:
1 PowerMate 1000
1 Power amplifi er, e.g. 2x250 watts
2 HI cabinets, e.g. 3-way 12" speakers
2 LO cabinets, e.g. 15" woofer
2 Speaker pole-stands or 2 connection rods
2 Stage monitor speakers
4 SPEAKON cables 8m, 2 SPEAKON cables 2m
1 LF-cable with a stereo phone plug on one side and an XLR-type connector on the other end
Setting Up
•
Place the PowerMate and the external power amplifi er 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 fl oor 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 pole-stands instead.
•
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
amplifi er. 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.
