Audio-Technica ES8755RC 5-Pin Flush-Mount Microphone Power Module

The Audio-Technica ES8755RC 5-Pin Flush-Mount Microphone Power Module provides a streamlined interface for ES925 gooseneck microphones and microphone elements. This module functions as a central connectivity hub, combining high-quality audio output with advanced logic control for boardroom and conference installations. The flush-mount design allows for an unobtrusive tabletop setup while maintaining full functional control over the audio environment.

Integrated Control and Automation

The ES8755RC features a touch-sensitive capacitive-type user switch that offers seamless interaction without mechanical noise. Logic I/O capability allows the module to control remote devices directly from the user switch. This external contact closure enables the triggering of external hardware, such as cameras or lighting systems, during a meeting. The contact closure operates with an input voltage range of -0.5 to 5.5V and maintains an on-resistance of 100 ohms.

Visual Status and Interface

This power module includes a highly visible, two-state RGB LED status indicator to provide immediate visual confirmation of the microphone's state. The LED control is TTL compatible with an active high (+5V DC) requirement. Users can easily identify mic on and mic off states via the distinct LED colors, ensuring clear communication status for all participants.

Installation and Mechanical Dampening

Designed for permanent tabletop integration, the ES8755RC mounts unobtrusively to maintain a clean workspace. The package includes a pair of isolators that provide essential mechanical dampening. These isolators effectively reduce the transmission of surface vibrations from the table to the microphone element, preserving audio clarity. The module features an integral 5-pin XLRM-type output connector for secure professional connections.
