Application Example (1)......Paging System
Note that the priority mute level potentiometer is adjusted to the maximum to allow the
mute feature to be fully active. This level can be adjusted mid way or so if it is to allow a paging
to be made with background music audible at lower volume.
Other equipments such as amplifier changeover, back up batteries, etc are not shown, which
may be required according to the building design requirements.

INSTALLATION AND CONNECTION
Ok, you have got this point and you are now in the position to successfully operate
. However, we advise you to read carefully the following section to be the real master
of you own mixer. Not paying enough attention to the input signal level, to the routing of the
signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no
sound at all. So you should follow these procedures for every single channel:
your mixer
preamplifier
1. Be connecting mics or instruments, make sure that the power of all your systems components
including the preamplifier is turned off. Also, make sure all of input& controls of your
preamplifier are turned down. This will avoid damage to your speakers and avoid excessive
noise.
2. Properly connect all external devices such as mics, mixers, speakers, processor.
3.Now, turn on the power of any peripheral devices, then power up the mixer.
Note: the power amplifier or powered monitors shall be turned on after
turned off before .
