5. INSTALLATION AND CONNECTION

Ok, you have got to this point you are now in the position to successfully operate your PM-8 DRAGONFLY. However,
we advise you to read carefully the following section to be the real Master of your own Mixer. Not paying attention enough
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 this procedure for every single channel:
Turn down all Input and Output Gain Controls.
Connect phantom powered microphones before switching on the +18Volt Phantom Power switch.
If you have a power amplifier connected to your PM-8 DRAGONFLY set the Level of the amplifier at no more than 75%.
Now, set the CONTROL ROOM / PHONES level at no more than 50%. In this way you will be able to hear later
you are doing connecting a pair of phones or a pair of powered studio monitor speakers.
Position HI, MID and LOW EQ controls on the middle.
Position panoramic (PAN) control on the center.
With a phone or studio monitor speaker connected apply a Line Level input signal so that the PEAK Led
light up.
At this point increase the input gain so that the PEAK led will blink occasionally. In this way you will maintain good
headroom and ideal dynamic range.
Now connect a microphone and ask the singer to sing loud into the microphone. Turn slowly the Gain Control clockwise
and have the PEAK Led blink only occasionally.
Now repeat the same sequence for all input channels. The Main Led Meter could move up into the red section.
this case you can adjust the overall output level through the MAIN MIX control.
