About the ASA Series

The Extron ASA series high-performance audio summing amplifiers convert stereo audio signals into balanced or unbalanced mono signals. The series consists of the following three models:

ASA 101 — The ASA 101 is a single, ultra-compact passive summing adapter with two male RCA pigtail connectors for one unbalanced stereo audio input. The unit has one 3-pole captive screw connector for one balanced or unbalanced mono output.

ASA 204 — The ASA 204 has four independent active summing amps with four pairs of RCA connectors for unbalanced line level stereo audio inputs. The unit has captive screw connectors for four balanced or unbalanced mono outputs. Because of its input/output configuration, the ASA 204 can also function as an unbalanced to balanced audio converter.

ASA 304 — The ASA 304 has four independent active summing amps with four 5-pole captive screw connectors for balanced or unbalanced line level stereo audio inputs. The unit has captive screw connectors for four balanced or unbalanced mono outputs.

The ASA 204 and ASA 304 include an external 12V power supply that accepts 100-240VAC input. The ASA 101 is a passive
