The PA-402 is a Professional Audio Power Amplifier designed with the System Integrator in mind. It is specifically designed for Background Music, and Paging Applications and may be used with other Tech Works products to augment a variety of system designs. The PA-402 has Program Audio Inputs, Paging Audio Inputs, and Control signals that select which Audio inputs are directed to the Speaker. These inputs are transformer balanced allowing several PA-402’s to be connected in tandem, for large distributed systems. There is also an unbalanced Stereo Input for “Local” Music insertion.
The logic allows for a wide range of control requirements including; Enabling, Muting, Program, or Page selection. Logic options are selected from a set of dipswitches located on the rear of the amplifier. The PA-402 comes ready to use for most applications, and there are Application Templates for other common uses.
The audio quality of the PA-402 is superb. The undistorted output is 40-Watts. The PA-402 is fully protected against overloads. The unit automatically recovers when any overload is removed.
Modular Construction makes the PA-402 ideal for integrated designs. The unit is small; mounting is flexible, and easy, so it is ideal for space conscious requirements. Mounting options include Desk Mount (DM), Rack Mount (RM), and Wall Mount (WM). All signals are connectorized for ease of installation.
Power is from a Universal Plug-in DC power adapter or screw terminals for connection of any regulated 24VDC-3.5 Amp Power Supply (Sold Separately).
