The IA-250 is a two channel mic/line audio mixer, and 20W Class D amplifier mounted in a 3-gang
in-wall box. It was designed to be compact and easy to operate, while providing high quality sound
reinforcement for a small room. Powered by it’s own 24Vdc plug-in power supply, the IA-250
means that your requirement for sound reinforcement is no longer dependent on the presence of an
19” rack.
Installation Overview
Setting up the IA-250 is quite easy. Please refer to the back of the IA-250, where terminal and
switch positions are etched in the copper, or to figure 1 below.
