descriPtio n
The Extron ASA 100 Series of Audio Summing Adapters are convenient, single-cable solutions
for combining two-channel stereo audio into a mono audio signal. They are 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 they are small and
passive devices, these Audio Summing Adapters are especially useful in systems where power
and space are limited.
The ASA 111, ASA 121, and ASA 131 feature connectivity options for popular stereo sources
such as RCA, stereo mini plug, or captive screw connectors. The ASA 141 features RCA input
connectors while an internal transformer provides a balanced output isolating the signal from
load and preventing ground loops. All ASA 100 series products are designed as 2 foot long
adapters with a resistor network to properly sum stereo signals without signal loss or damage
to source equipment.
