The TOA B-41S Balanced Line Input Module is a professional-grade solution for integrating both balanced and unbalanced line-level audio sources, including AM/FM tuners, tape decks, and CD players. Its transformer isolation effectively prevents ground loop interference, ensuring clear, stable, and noise-free audio signals in any commercial or professional environment.
The B-41S features a mute-send function, which activates the system mute bus when a signal is detected at the input terminals. This allows seamless integration with paging systems, background music, and other audio control applications, enhancing operational flexibility and system responsiveness.
Additional features include adjustable mute-send sensitivity, a 10 kΩ input impedance, input sensitivity ranging from -16 dBu to -34 dBu, and a removable terminal block for easy installation.
