TOA T-01S-T – Balanced Line Output Module, 900 Series

Product Overview

The TOA T-01S-T is a transformer-balanced line output module for the TOA 900 Series modular amplifier and matrix mixer platform, adding a balanced line-level output to the system for connection to downstream signal processing equipment, recording interfaces, or additional amplification stages. Line output modules allow a TOA 900 Series amplifier to simultaneously drive its loudspeaker zones and provide a balanced analog feed to an external processor or zone controller without additional signal splitters or output transformers. Commercial AV integrators designing TOA-based distributed audio systems that require a balanced output tap—such as for a digital audio recorder, a VoIP paging interface, or a monitor feed—will find the T-01S-T provides this function directly within the 900 Series chassis. The adjustable gain control on the module allows output level trimming to match the input sensitivity of downstream equipment.

Product Description

The T-01S-T installs in any available module slot in a compatible TOA 900 Series mixer-amplifier or matrix mixer chassis, adding a transformer-balanced line output with a gain control knob and a removable screw-terminal block for output cabling. The transformer-balanced output provides common-mode noise rejection and ground-loop isolation to the downstream signal path, which is important when the output feeds equipment in a different electrical zone or enclosure from the 900 Series amplifier chassis. The onboard gain control enables output level adjustment without changes to upstream signal processing, allowing the T-01S-T output to be trimmed to the optimal input level for any connected device. For TOA 900 Series installations in conference centers, multi-room facilities, or broadcast-adjacent commercial AV systems where a parallel balanced output is part of the system design, the T-01S-T provides that function in a compact plug-in module that keeps all output conditioning within the amplifier frame. The removable terminal block follows TOA's standard module wiring practice, enabling pre-termination of the output cable before the module is seated in the chassis.

Key Features

• Transformer-Balanced Line Output — Provides a transformer-isolated balanced line-level output with strong common-mode rejection for noise-free signal delivery to downstream AV equipment.
• Gain Control — Onboard level adjustment trims the output to match the input sensitivity of connected DSPs, recorders, paging interfaces, or other professional AV devices.
• 900 Series Plug-In Compatible — Installs in available module slots in TOA 900 Series mixer-amplifiers and matrix mixers for streamlined output expansion within the existing chassis.
• Removable Screw-Terminal Block — Detachable connector enables pre-wiring of the output cable before module installation, reducing on-rack assembly labor.
• Parallel Output Architecture — Provides a line-level output tap without interrupting the amplifier's primary loudspeaker drive path, enabling simultaneous operation of distributed speakers and downstream signal processing.
