The Extron ASA 131 Audio Summing Adapter is a convenient, single-cable solution for combining two-channel stereo audio into a mono audio signal. It is ideal for summing stereo signals for use in mono PA systems in churches, halls, arenas, stadiums, and other environments where stereo signals would result in cancellation. Because it is a small and passive device, the ASA 131 is especially useful in systems where power and space are limited.

The ASA 131 includes a captive screw plug for balanced stereo input signals and a captive screw connector for balanced mono audio output. It is designed as a 2 foot long adapter with a resistor network to properly sum stereo signals without signal loss or damage to source equipment.
