IA-250 2 Ch. Mixer/20W Class D Amp 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.

IA-250 2 Ch. Mixer/20W Class D Amp Setting up the IA-250 requires selecting between microphone or line input for each mixer channel, and selecting between phantom power or no phantom power for each mixer channel. After making those selections, wiring the inputs, speaker output and applying power is all that is required to complete the installation. Installation The IA-250 Mixer/Amplifier should be mounted into a standard 3-gang in-wall box.

IA-250 2 Ch. Mixer/20W Class D Amp IA-250 Switches Step Two: Locate the phantom power selector switches on the back of the IA-250. The phantom power switches are the two top switches on the printed circuit board (see figure 2 above). Select phantom power for mixer channels by choosing between on or off. Note: Phantom power is supplied on microphone inputs to provide power to a microphone, so a channel being set-up for line input should have phantom power turned off.
