Speaker line connection
Each amplifier has a 100V high impedance output for connecting the speaker line.
When working with 100 V lines, the following must be remembered:
-
The loudspeakers must be provided with a line transformer.
-
The total connected power shall be the sum of the powers absorbed by the loudspeakers and should be between 50% below
and 10% above the rated power of the amplifier.
The DA-4PM/0F2 constantly monitors the status of the speaker line output. If a short-circuit is detected on the speaker line, the
front LED PROTECT and the yellow LED on the rear RJ45 of the corresponding amplifier flash.
For the connection of the loudspeaker line in installations with surety paging relay, please follow section
For this type of
installation it is necessary that the DA-4PM/0F2 is equipped with the RSAP-F2 accessory module (one per amplifier). See section
