The TOA 900 Series Balanced Line Input Modules are expansion cards designed for integration into TOA 900 Series mainframes and compatible TOA equipment in installed sound environments. These modules accept balanced or unbalanced line-level signals from sources such as mixer outputs, signal processors, wireless receiver outputs, tuners, CD players, and tape decks, making them a core building block for paging, background music, and distributed audio systems in commercial, institutional, and hospitality installations.
Across the family, transformer isolation provides electrical separation between source and system, protecting signal integrity and reducing noise in complex multi-zone installs. Variants are offered with input impedances of 10kΩ or 600Ω to match specific source requirements, and with mute-receive, mute-send, or remote volume control functionality to suit different system control architectures. Connector options span removable terminal block and screw terminal configurations to accommodate field wiring preferences.
For integrators building or expanding TOA 900 Series systems, these modules offer a direct, manufacturer-matched solution with consistent physical dimensions across the family. The flat frequency response and transformer isolation make them a more reliable choice than passive alternatives or third-party adapters in environments where system coherence and long-term serviceability matter.
