The TOA 900 Series Unbalanced Line Input Modules are plug-in input cards engineered for use within TOA 900 Series amplifier frames and compatible TOA equipment. Designed for installed AV environments such as houses of worship, retail spaces, corporate facilities, and multi-zone paging systems, these modules give integrators a modular, scalable path for connecting unbalanced line-level sources including CD players, tuners, mixers, computer sound cards, and satellite receivers. Because they are intended for adjacent sources within 15 feet of the host frame, they are best suited for rack-room or back-of-house signal routing rather than long-run infrastructure.
Across the family, modules are available with a range of connector types and functional capabilities to match specific installation requirements. Certain variants include high-cut and low-cut filters for tone shaping at the input stage, while others add mute-receive or mute-send functions that integrate with the 900 Series mute bus, enabling system-wide priority routing or paging override without external relays. Additional variants provide compressor and remote volume control functions, giving system designers precise dynamic management and zone-level volume adjustment from a remote potentiometer. Each module slots directly into the 900 Series frame, keeping the signal chain clean and the rack footprint compact.
For integrators specifying 900 Series systems, this module family removes the need for external line-matching hardware by handling gain adjustment, filtering, and control functions at the frame itself. The combination of modular form factor and varied functional options makes the range a practical choice for phased installations where input requirements may evolve over time.
