2.2 Description
The Transfer Unit has 8 internal transformers to convert the 8
Ω
loudspeaker outputs of the Digital Amplifier unit into
constant voltage lines (100 or 70V) for loudspeakers having transformers. The default output voltage is 100 V; contact
your authorized service center to change the output voltage to 70V if necessary. If the required power for a loudspeaker
line is higher than 80W, it will be necessary to combine more outputs to make a Locked Group (controlled as a single
output).
‘OVERRIDE’ 24 V dc outputs are available for override relays. If AAC 200 Amplifier Change Modules are used to have
faulty amplifier change-over feature, override voltage is not available.
2.3 Front Panel
1. ‘PRIORITY’ LED ( x 8, 1 per each output) indicating the activation of the ‘OVERRIDE’ 24 V dc command when paging
or faulty amplifier change-over is activated.
2. ‘ON’ LED (note: this LED indicates that the unit is 24 V dc supplied for all internal LED's and ‘OVERRIDE commands
on its rear panel; the internal transformers do not need this power supply).
