FSR ASA-4 overview

  • 1Description

The ASA-4 from FSR is a device that sums the audio from its 4 line-level inputs to its single line-level output. Each input features a 3 conductor terminal for both balanced and unbalanced signals and a trim pot to adjusting the level. The output features a 3 conductor terminal, and it also has an integrated transformer coupling that eliminates ground loop issues and makes longer cable runs possible.

Several different sound sources can be inputted into the ASA-4. It accepts both professional and consumer line-level audio. You can attach the outputs of a professional mixer, and the outputs of a consumer CD or MP3 player, and the ASA-4 is equipped to pass their audio to its output. It's a great way to have several different components of your sound system share the input of a power amplifier/speaker system. The ASA-4 is ideal for permanent installations in bars, restaurants, hospitals, schools, and businesses.
