The Extron ASA 141 Audio Summing Adapter is a convenient, single-cable solution for combining two-channel stereo audio into a balanced or unbalanced 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 141 is especially useful in systems where power and space are limited.

The ASA 141 includes two 6 inch leads with male RCA connectors for stereo input signals and captive screw connectors for balanced/unbalanced 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.
