TOA B-01S T 900 Series Balanced Line Input Module With Transformer

The TOA B-01S T is a line input module designed for use within TOA's 900 Series modular amplifier platform. It accepts balanced or unbalanced line-level signals from mixer outputs, signal processors, and wireless microphone receivers, making it a practical expansion option for installed audio systems that require clean, reliable source integration.

Transformer isolation at 10kΩ ensures common-mode noise rejection between source equipment and the amplifier chain, a critical requirement in installed AV environments where ground loops and long cable runs are common concerns. The removable terminal block simplifies field termination and allows modules to be swapped without disturbing the wiring harness, a workflow advantage during commissioning or maintenance of fixed installations in commercial facilities, houses of worship, schools, and similar venues.

For integrators building out TOA 900 Series systems, the B-01S T provides a purpose-engineered input stage that maintains signal integrity across the full audio bandwidth. Its compact module format fits the 900 Series architecture, preserving the scalable design intent of the platform rather than requiring external adapters or passive pads.
