6.0 Setup
6.1 Determining Source Priorities
Determining the hierarchy of your sources is easier than it sounds. Generally, it follows this order:
1. Emergency/Alarm (Direct Input with MUSIC MUTE engaged)
2. Pages (Paging Mic)
3. Prerecorded announcements (or another source into SOURCE 1 with Priority engaged).
4. Background music (SOURCE 2 and SOURCE 3)
In this example, your alarms would connect to the Direct Input, your page microphone connects to the
MIC Input, prerecorded announcements connect to SOURCE 1, and background music connects to
SOURCE 2 and 3.
NOTE:
MUSIC MUTE DOES NOT MUTE THE PAGING MIC. IN AN EMERGENCY SITUATION IT IS
USUALLY BEST TO KEEP ALL MICROPHONES ACTIVE FOR EMERGENCY ANNOUNCEMENTS.
6.2 Connecting Sources
Connecting your sources is also very simple. Just connect the left and right outputs of your source to the
left and right input of the mixer.
6.3 Adjusting Source Gain
Check the input level LEDs, they should light green for continuous signal. Red will flash if the input is too
strong. Occasional flashes into the red are not harmful if no distortion is apparent.
6.4 Using EQ
The best determination for needed equalization is to trust your ears. Does the output sound boomy?
Reduce the bass setting or engage the high pass filter, this will reduce the bass frequencies. Does it
sound dark or muffled? Turn up the treble. Or if it sounds thin or harsh, decrease the treble. Just like the
tone controls on a car or home stereo.
