SETTING UP A STANDARD-PA SYSTEM
• Place the CMS and all connected appliances 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 main PA 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 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 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 positioning the main loudspeakers behind the imaginary line of microphones. Otherwise, if you have to drive the
system at higher sound pressure 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. However, 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 between woofers, monitor speaker systems and all other appliances as shown in the set-up examples.
Make sure to observe all notes provided in the owner’s manuals of
all appliances in use. Make sure not to confuse channels by
accident.
• Connect all microphones preferably to the monaural inputs of the CMS and keyboards and other comparable sound sources to
the rest of the available inputs.
• Pull all faders down and engage the STANDBY button on the CMS to prevent unwanted feedback noise.
• First, switch on all external devices, then the CMS and at last power amplifi ers and active speaker systems.
• In case you have condenser microphones connected to the CMS and turn on phantom power by pressing the corresponding
PHANTOM POWER switch.
• Activate the CMS’ operational mode through pressing the STANDBY button again.
Sound Check
•
First, adjust the input levels of the microphones that are connected to the monaural and/or stereophonic inputs on the CMS.
Please proceed as follows:
1. Set gain controls and channel faders to their lowest position.
2. Speak or sing as loud as possible into the microphone.
3. Use the gain control to adjust the level, so that even at loud passages the red PEAK LED does not light but the green
SIGNAL LED lights constantly.
• Adjust the tone controls of the monaural input channels:
1. Slide the channel fader and the master faders up a bit, so that the sound coming from the main speakers is heard.
2. Turn the MID control carefully all the way clockwise (+15dB). You should not hear any feedback.
3. Play the sound source or speak into the connected microphone
4. Turn the frequency control (kHz) slowly from left to right.
5. Surely and within no time, you will detect the frequency range that is not to your liking or causing feedback noise.
6. Leave the frequency control in this position and turn the MID control in the counterclockwise direction until the sound is
natural or to your liking.
7. If necessary, adjust the Hi and LOW controls, starting from their center position, until the sound matches your personal
taste.
8. Repeat steps 1 - 7 for all monaural input channels in use.
• In case you are also using the stereo input channels, adjust their levels in a similar way:
1. Set LINE TRIM controls, MIC gain controls, and channel fader to their lowest setting.
2. Play the corresponding sound source at the highest volume that is to be expected during the performance.
3. Use the LINE TRIM control to adjust the level, so that even at loud passages the red PEAK LED is not lit but the green
SIGNAL present LED lights constantly.
• Adjust the tone controls of the stereophonic channels:
1. Slide the channel fader and the master faders a bit up, so that you can hear the sound through the main speakers.
2. Set the EQ controls to their center position.
3. Play the corresponding sound source.
4. Starting from the center position, you can adjust the controls until the sound is to your liking. Please, keep in mind that
major alteration of the EQ-setting does not necessarily result in the improvement of the overall sound. Especially when
sound shaping is concerned, less can be more.
5. Repeat steps 1 - 4 for all stereo input channels in use.
• If musical instruments are connected at the monaural inputs, follow the descriptions above for adjusting the microphones.
• Make sure, that all channel faders, gain and LINE TRIM controls of unused input channels are at their minimum setting. In this
way you avoid unnecessary noise at the outputs.
