TOA B-21S – 900 Series Bridging Transformer Line Module
Overview
The TOA B-21S is a plug-in bridging transformer line input module for the TOA 900 Series modular mixer/amplifier platform. Its high-impedance input with built-in isolation transformer allows connection of balanced or unbalanced line-level sources—CD players, satellite receivers, streaming devices, and building automation audio outputs—while eliminating ground loops and hum in professional installed systems.
Key Features
- Bridging transformer isolates line-level source from amplifier ground
- Accepts balanced and unbalanced line-level inputs
- High input impedance minimizes signal loading
- Variable input level and output trim controls
- Bass and treble EQ adjustment
- Plug-in module for all TOA 900 Series mainframes
