TOA B-01S T – 900 Series Line Input Module

Product Overview

The TOA B-01S T is a transformer-balanced line input module for the TOA 900 Series mixer-amplifiers and modular electronics. It lets integrators add a balanced line-level input to a 900 Series chassis to accept mixer outputs, signal processors, or wireless microphone receivers. As a TOA 900 Series line input module, the B-01S T uses a removable terminal block for fast, secure field wiring in distributed audio systems. It is the right plug-in card when a commercial paging or background-music amplifier needs another clean line source.

The B-01S T installs into an open module slot on a compatible TOA 900 Series amplifier or mixer, expanding the system without an outboard interface. Its transformer-balanced input rejects common-mode noise on long cable runs, which is essential when a head-end rack feeds audio across a large commercial building. The removable terminal block connector lets technicians pre-wire the plug, land bare-wire feeds quickly, and service the module without disturbing adjacent cards. Because the module is part of the native 900 Series architecture, gain staging and signal routing follow the host frame rather than requiring separate power or configuration. Typical sources include the output of a house mixer, a DSP or matrix processor, or the line output of a wireless receiver in a presentation room. The balanced design keeps hum and buzz out of the program feed even in electrically noisy mechanical spaces. For contractors standardizing on TOA modular electronics, the B-01S T is a straightforward way to add an input channel.

Key Features

• Transformer-Balanced Input — Rejects common-mode noise on long balanced runs to keep program audio clean across a distributed system.
• 900 Series Plug-In Design — Installs directly into a TOA 900 Series mixer-amplifier slot, drawing power and routing from the host frame.
• Removable Terminal Block — Lets technicians pre-wire and land bare-wire feeds quickly, simplifying installation and future service.
• Flexible Source Support — Accepts balanced or unbalanced line-level signals from mixers, DSP processors, and wireless microphone receivers.
• Built for Commercial AV — Suits paging, background music, and distributed audio head-ends that need an additional clean line input.
