PA Power Amplifier
These instructions are intended for installers
with specific knowledge in sound reproduc-
tion using 100 V technology . Please read the
instructions carefully prior to installation and
keep them for later reference .
1 Applications
The amplifier PA-1500D with a rated output
power of 500 W is specially designed for
applications in PA systems . It is equipped with
a line level input for background music and
standard announcements . A second line level
input is provided for emergency announce-
ments or other important announcements .
A separate switch or an external relay can be
used for switching over to the second input .
2 Overview
Note:
To make handling easier, all green terminal
strips can be disconnected from their plug-in con-
nections .
