TOA L-01ST – Balanced Line Matching Input Module, 9000 Series

Product Overview

The TOA L-01ST is a transformer-balanced line matching input module for the TOA 9000M2 Series and 9000 Series matrix mixer/amplifier platforms, providing a high-impedance balanced line input suited for long-run distributed audio signal routing in commercial environments. The 600-ohm matching transformer delivers consistent impedance matching and common-mode noise rejection, essential when accepting signals from broadcast interfaces, DSP outputs, or background music sources over extended cable distances. AV integrators building out TOA 9000 Series systems in large commercial AV installations—such as corporate campuses, multi-zone retail spaces, or government facilities—rely on the L-01ST to expand the system's line input count without external mixing equipment. The removable terminal block simplifies installation and future service access.

Product Description

The L-01ST slots directly into any available module position in a compatible TOA 9000M2 or 9000 Series matrix mixer/amplifier chassis, adding a single transformer-balanced line matching input to the system's signal routing matrix. The 600-ohm impedance of the L-01ST's transformer input stage is consistent with professional audio bridging standards, enabling direct connection from balanced outputs on DSP units, audio matrix processors, and media playback equipment. Removable terminal block wiring allows pre-termination of input cables before the module is seated, a practical advantage in rack-dense commercial AV installations where headroom is limited during final assembly. For integrators specifying TOA 9000 Series systems in conference centers, multi-room facilities, or mixed-use commercial buildings, the L-01ST is the correct module when the system design calls for a standard 600-ohm balanced line input on a transformer-isolated path. The module's compact plug-in form factor keeps all signal conditioning inside the amplifier chassis, reducing external equipment count and simplifying system maintenance.

Key Features

• Transformer-Balanced 600-Ohm Line Matching Input — Provides proper impedance matching and common-mode noise rejection for professional balanced line signals from DSPs and source equipment.
• 9000M2 and 9000 Series Compatible — Designed as a plug-in module for TOA 9000 Series and 9000M2 matrix mixer/amplifier chassis, expanding system input capacity without external hardware.
• Removable Terminal Block — Detachable screw-terminal block enables pre-wiring of input connections before module installation for faster, cleaner system commissioning.
• Transformer Isolation — Breaks ground loops and rejects interference from shared AC infrastructure common in large commercial buildings with multiple AV zones.
• Compact Plug-In Design — Fits entirely within the TOA 9000 Series chassis module slot, keeping signal conditioning inside the amplifier rack frame and minimizing external cabling.
