Installation of the DA-1 Power Amplifier Module
The EMS-152 fullrange loudspeaker and EMS-215 subwoofer can accept the EM Acoustics DA-1 digital power
amplifier module. One DA-1 is used to drive one loudspeaker, in the following configurations:
EMS-152 – bridge-mono mode, with the two amplifier channels driving the internal passive circuitry.
EMS-215 - two channel mode, with each drive unit driven by one channel.
To install the DA-1, lie the enclosure on its front. Using a 4mm Allen Key, carefully undo the six M5 socket head
bolts holding the connector panel door in place on the rear of the enclosure. Remove the connector panel door
and disconnect the four-pin connector on the cable. Put the connector panel aside for future reinstatement.
Connect the four-pin connector into the chassis socket on the bottom edge of the DA-1. Carefully place the DA-1
into the amplifier module housing within the enclosure, reinstate and retighten the M5 socket head bolts.
The DA-1 must be set to the correct program before use, otherwise severe damage can occur to your loudspeaker.
Please consult your DA-1 user manual for information on recalling programs, and a program listing.
