ASA Audio Summing Adapters
(ASA 111, ASA 121, ASA 131, ASA 141)
The Extron ASA audio summing adapters sum left and right stereo audio signals into
mono signals for distributed sound and other applications that require mono sound.
The ASA 111 and ASA 121 output an unbalanced audio signal only. The ASA 131
outputs a balanced audio signal. The ASA 141 outputs a balanced or unbalanced audio
signal.
