OUTPUT PTT 24V DC COM 8Ω 70V 100V The OSD PA90 output module, including PTT ( Push To Talk ), 24V DC back up power supply, 8 ohm output, 70V output and 100V output, is using the screw terminal connectors. Limited Warranty If you will use 8 ohm output, connect the speaker’s positive terminal to the amplifier’s “8Ω” terminal and connect the speaker’s negative terminal to the amplifier’s “COM” terminal.
APPLICATIONS USING DC 24V POWER SUPPLY CONNECTING 8 OHM SPEAKERS In this configuration, a DC 24V power supply is connected to PA90 to help it to be used in mobile applications or in applications that must continue to operate in case of a AC power failure. In this configuration, the 8 ohm speakers are connected to the “8Ω” and “COM” terminals. The output of PA90 will then deliver the rated output power into an 8 ohm load.
