Soundfield ‒ Reference & Installation Guide B45IRCINS4 V4.0
An overview of the installation steps are:
1)
Charge transmitter batteries for testing purposes.
2)
Decide where the speakers are to be fitted.
3)
Decide where to fit the Infra Red sensors.
4)
Decide where to mount the IR Classmate amplifier
5)
Decide the easiest cable run for the speakers and sensors.
6)
Install the system.
7)
Setting up and testing the system.
8)
Demonstrate and set the volume level for the user.
1. Charge batteries now
The rechargeable batteries inside your transmitter require charging before use. In order
to be able to test the system once it is installed, we recommend you use the external
charger, if you have one, to start charging the transmitter. Alternatively, you could plug
the unmounted amplifier into an available socket and start charging the transmitter
before carrying on with the installation.
Even an hour or so will give enough charge to test the system ‒ 1 hour charge gives
40mins use.
2. Deciding where to fit the speakers
Firstly please do not think home hi-fi and put the
speakers in the corners, at waist level and point them to
the centre of the room ‒ this is the worst possible thing
to do!
Placing loudspeakers for a classroom soundfield is more
like deciding how best to light a room using 4 small
lamps. If you think ‘light’ you will not go far wrong, i.e.
fitted above head height (2 to 2.5 metre high) each over
a 1/4 of the room pointing down on the area to be
covered.
The positioning of speakers is often dictated by physical
objects such as windows. You have to fit 4 (or 6) speakers
so adapt your ‘lighting’ plan to give the best pattern for
the students ‒ perhaps avoiding the window, an unused
end of a classroom or a teachers desk.
