Electro-Voice STEREO POWERED MIXER PSX2200 - Manual (Page 20)

In this chapter we would like to explain how to install a typical sound reinforcement system in passive configuration and incorporating stage
monitor speakers. The necessary equipment is:
1 PSX
1 Power amplifier for the monitor signal
2 Speaker Systems
2 Woofer cabinets
2 Speaker stands or 2 pole mounts
2 Stage monitor speakers
4 SPEAKON cables (8m), and 2 SPEAKON cables (2m)
1 Balanced LF-cable with a stereo phone plug on one side and an XLR-type connector on the other side
Setting up
•
Place the PSX and the external power amplifier in a way that allows their unobstructed operation during the sound check and performance.
•
Try to locate the best position to place the loudspeaker systems. If possible, the woofers should be placed on the floor while the cabinets’
most favorable position is above the woofer systems, on the same vertical axis. It is important that the lower edge of the is approximately
at the same height level as the heads of the audience. Either use the pole mounts for the top of the woofers or, in case this kind of
installation is not possible in your application, use separate speaker 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 impact to the sound.
•
Try to avoid positioning the main loudspeakers behind the line of microphones. If you have to run the system at higher sound levels, the
risk of feedback is very high.
•
When the microphones are placed and all musicians ready, place the monitor speakers facing the musicians. Make sure no microphone
is pointing directly into a monitor. 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 PSX’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
output of the external amplifier. The amplifier should be run in a parallel mono configuration so that the amplifier’s volume controls provide
the capability to adjust the output levels separately.
•
Connect the PSX’s AUX3 SEND with the external amplifier’s input, using a balanced NF-cable with the stereo phone plug on one end
and the XLR-type connector on the other.
•
Connect all microphones to the monaural inputs of the PSX and the keyboards and other comparable sound sources to the rest of the
available inputs
