TEKVOX now offers a small affordable multifunction room amplifier with many features including RS-232 control. The
TEK-PA2B has all of the features you need without breaking your budget. This compact-size digital amplifier (Class-D)
has 3 inputs (2 selectable line inputs and 1 balanced MIC with selectable phantom power). It is integrated with powerful
features including speaker bridging, stereo or mono selection, EQ control, microphone mixer and simple to program
RS-232 control.
This simple to use amplifier is great for classroom and training room amplification including speech reinforcement. With
separate volume controls for the line inputs and the Mic input, controlling the room level without feedback is easy.

Application
In this application there are two different selectable music inputs and a microphone input all controlled by the
TekTouchPad. A second TEK-PA2B is added to connect a second group of speakers. Since the Loop output is after the
volume control, adding another amplifier is easy. Any change of the volume level will also control the level of the second
amplifier.
