Unbalanced Line Input Module- Lo/Hi-Cut Filters- Removable Terminal Blck

The TOA U-43S is a 900 Series unbalanced line input module featuring Lo/Hi-cut filters and a removable terminal block connector. Its focused configuration brings line-level input, filter controls, and terminal-block connectivity together in a single module. The available source specification also lists a 100 Hz refresh rate. Because no additional electrical, physical, or compatibility specifications are provided, system requirements should be verified before purchase.

Ideal Use Cases

The U-43S is suited to installations that specifically call for a TOA 900 Series unbalanced line input module. It provides a defined option for bringing an unbalanced line source into an appropriate modular system while retaining access to both low-cut and high-cut filtering. The removable terminal block makes it relevant where terminal-based wiring is required. This model should be selected by its U-43S designation when matching an existing system specification, replacement requirement, or documented equipment schedule.

Why Choose This Model

Choose the U-43S when the required feature set includes an unbalanced line input, Lo/Hi-cut filters, and a removable terminal block. These documented elements clearly establish the module’s purpose without adding unrelated connections or functions to the selection criteria. The model designation and 900 Series identification also make the product straightforward to reference in purchasing documents and system plans. Available information does not specify channel count, input sensitivity, gain range, impedance, or power requirements, so those details should not be assumed.

Installation and Integration

The module uses a removable terminal block connector. This connector format allows the terminal block to be handled separately from the module during wiring or equipment preparation. The source data does not identify terminal count, wire size, pin assignments, mounting procedure, or the systems with which the module is electrically compatible. Installers should therefore use the U-43S model number and 900 Series designation to confirm suitability with the intended host equipment and installation documentation. No dimensions, weight, voltage, operating-temperature range, accessories, or included hardware are listed in the available product data.

Performance Highlights

The core signal-related features are the unbalanced line input and the Lo/Hi-cut filters. The filter names indicate that controls for the low and high portions of the signal range are part of the module’s documented feature set. Specific cutoff frequencies, slopes, adjustment ranges, frequency response, distortion figures, noise measurements, and signal-to-noise performance are not provided. A value of 100 Hz appears in the source technical specifications under the label “refresh rate”; the available data does not further define that measurement or identify it as a filter cutoff frequency.

What Makes It Different

The U-43S combines three clearly identified characteristics: an unbalanced line input, Lo/Hi-cut filtering, and removable terminal-block connectivity. This combination distinguishes the model within the limited information supplied and provides concrete criteria for comparing it with other 900 Series modules. Rather than relying only on a broad product-family name, buyers can match the U-43S against the precise input type, filter description, and connector format required by their project. No HDMI, USB, network, wireless, video, projection, built-in speaker, or other connectivity capabilities are documented for this module.

Final Assessment

The TOA U-43S is a purpose-identified 900 Series module for applications requiring an unbalanced line input with Lo/Hi-cut filters and a removable terminal block. Its documented attributes make it possible to confirm the basic module type and connection method before ordering. The supplied information does not establish broader compatibility or detailed audio performance, so final selection should be based on the U-43S model designation and verified system documentation. For a replacement or specified installation, confirm the host equipment, wiring assignments, and required operating characteristics before installation.
