Microphone Input Module, Balanced, 600OHMS, Lo/Hi Cut Filters Remote Vol

The TOA M-11S T is a 900 Series microphone input module built around a clearly defined set of audio input and control functions. The module provides a balanced microphone input with a 600-ohm specification, low- and high-cut filters, and remote volume functionality. It also includes two mute response modes and uses a removable terminal block for connection. These documented capabilities make its intended role and integration requirements easy to identify when planning a compatible modular audio system.

Ideal Use Cases

This model is suited to TOA 900 Series system designs that require a balanced microphone input and a specified 600-ohm connection. Its combination of low- and high-cut filters is relevant where input filtering needs to be available directly at the module. Remote volume functionality also makes the M-11S T appropriate for installations in which the microphone input level must be controlled from another location. The two available mute response modes support systems that require either normally-on or normally-off behavior during mute control.

Why Choose This Model

The M-11S T combines several related microphone-input functions in one 900 Series module. Its balanced input addresses the core microphone connection, while the documented low- and high-cut filters provide two forms of input filtering. Remote volume functionality adds a separate control capability without changing the module’s primary role. The mute response can operate as normally on, meaning the output is off during mute activation, or normally off, meaning the output is on during mute activation. This defined behavior helps identify whether the module matches the mute logic required by a planned system.

Installation and Integration

The supplied product information identifies the M-11S as a TOA 900 Series module and specifies a removable terminal block connector. This connector format should be considered when preparing the associated wiring and installation plan. System compatibility, terminal assignments, chassis requirements, power specifications, physical dimensions, and mounting procedures are not included in the available data and should be confirmed before installation. The same applies to the exact implementation of remote volume control and the low- and high-cut filters, since control ranges and connection details are not stated.

Performance Highlights

• Balanced microphone input
• 600-ohm specification
• Low-cut and high-cut filters
• Remote volume functionality
• Normally-on and normally-off mute response modes
• Removable terminal block connector
• Listed refresh rate of 25 Hz

The available technical specifications list a 25 Hz refresh rate. No additional context is provided for that value, so it should be treated as a published module parameter rather than interpreted as an audio frequency-response figure. Likewise, no gain range, filter frequency, signal-to-noise ratio, distortion rating, maximum input level, or frequency-response range is supplied. Buyers comparing the M-11S T with another module should base the comparison on the documented functions above and obtain any additional performance data needed for the intended system.

What Makes It Different

The distinguishing feature set is the combination of balanced microphone input, 600-ohm specification, dual cut-filter functions, remote volume capability, and selectable mute behavior within a 900 Series module. The mute modes are described precisely: normally on becomes off when mute is activated, while normally off becomes on when mute is activated. That explicit definition is especially useful when evaluating control behavior. The removable terminal block is another clearly stated integration detail, allowing connector requirements to be considered before the module is selected.

Final Assessment

The TOA M-11S T is a focused microphone input module for applications requiring the specific functions documented here. It brings together a balanced 600-ohm microphone input, low- and high-cut filters, remote volume functionality, two defined mute response modes, and a removable terminal block. It is best selected when those capabilities align with the intended TOA 900 Series installation. Requirements involving dimensions, electrical ratings, detailed audio measurements, control wiring, or included accessories should be verified separately because they are not present in the supplied product data.
