Connections for video include Component (Y/Y, CP/PB, CR/PR), Composite video, SVHS and VGA connections.
Multiple PPA units can be connected together to create a larger system by connecting a 6.3mm mono jack lead from the
ACTIVE BUS OUT of one PPA unit to the ACTIVE BUS IN of a second PPA unit. This connection can be repeated from the
second PPA unit to a further unit and so on until a chain of PPA units is created.
If the unit is to be run from mains power, connect the supplied IEC lead, checking the supply voltage is correct.
Switch on the POWER switch on the front panel and turn up the MASTER volume gradually.
If a CD, DVD or karaoke disc is to be used for playback, press OPEN/CLOSE button on either front panel or remote
control to open the drawer unit, carefully position the disc in place and press OPEN/CLOSE again.
If a USB pen drive or SD/MMC card with compressed digital audio is to be used for playback, insert this media into the
correct slot on the front panel.
