Packs A, B, C, F & G:
Before testing the system, ensure that all the
batteries required for the transmitters are fully
charged.
After checking all the connections and wiring, set
the line and mic level controls to the half way point
then connect the unit to the mains supply.
The Power LED on the ampli
fi
er (of either a Panel
Ampli
fi
er or the IRX) will illuminate together with
the green LEDs on any Outreach plates
fi
tted. (If
the green LEDs fail to illuminate, disconnect the
supply and check the connections to the Outreach
plates are correct.)
For Packs A, B and C
only
:
Set output level switch on the IWR-220 to MIC and
switch the Receiver on; the red LED on the front
panel should illuminate together with those
fi
tted
to the external IR sensors. The
fi
xed equipment
should now be operating.
Next test the APA/APL input plate(s) by feeding in a low level signal from a music source such as a CD, MP3 or
laptop. Set the volume control on the plate to maximum then adjust the line input on the Sound Panel ampli
fi
er or
IRX to produce a reasonable level over the room.
Remember a Soundfield System is not a PA system
- the objective is to provide a comfortable listening level over
the entire room. In an empty room the system needs to be set slightly louder than would normally be required. Do
not try to adjust the tone controls at this point.
If more than one plate of the same type has been installed, all should be tested using the same method. If different
type Outreach plates have been installed, each should be tested using a suitable input source.
Now set up and test the infrared microphone transmitters using the procedures on pages 15 and 16. If the system
includes an IWH-301 hand mic as well as a IWM-302 beltpack, then set the hand mic
fi
rst.
