3. INSTALLATION AND CONFIGURATION
3.1.
Starting the equipment
DO NOT PLUG IN THE UNIT.
1. Install the dust filter if the unit’s environmental quality requires it (see diagram next page).
2.
With the FM Mod Amplifier option:
connect the transmitter RF output to a 50 ohm
charge with a wattmeter (see connection diagram next page).
The 50 ohm charge power to use depends on the transmitter power:
¾
Greater than 2 W for a 0.5 W transmitter.
¾
Greater than 30 W for a 20 W transmitter.
¾
Greater than 150 W for a 100 W transmitter.
When you acquired your Digiplexer 246, the RF amplifier is deactivated and power is set to 0.
These settings will then be adjusted using the front panel application.
For safety reasons, always deactivate the amplifier and the power if the Digiplexer 246 is
not in use.
3. Connect the inputs. The AES input is the default main source, but if the analog input is the only
connected input it will become the main source. Please read the Sound4 manual for input
management.
4. Connect to power using provided cable (or cables with “Redundant power supply” option). Press
the reset button using an adjustment screwdriver.
3.2.
Installing the dust filter
1. Using a phillips screwdriver, unscrew the 5 screws from the front panel so as to be able to
remove it.
2. Set de dust filter in front of the fan, with the grid towards the fan.
3. Screw the front panel back in place with the 5 screws.
Note
: make sure the fan works properly after starting the unit. If not, the front panel might not be
properly screwed.
