Audio-Technica ES8766RC 5-Pin Desk Stand Microphone Power Module

The Audio-Technica ES8766RC is a specialized 5-pin desk stand power module designed for use with ES925 goosenecks and microphone elements. This module provides a stable, high-performance base for professional audio environments, including boardrooms and conference centers.

Customizable User Controls

The unit features a touch-sensitive capacitive-type user switch that offers local and remote switching options. For local operation, the switch supports three distinct modes: touch-on/touch-off, touch-to-talk, and touch-to-mute. A highly visible, two-state RGB LED status indicator provides immediate visual feedback regarding the microphone state.

Logic I/O and Remote Integration

The ES8766RC includes logic I/O capability, allowing the touch-sensitive switch to control remote devices. The external contact closure permits the triggering of external equipment, such as cameras or lighting systems, directly from the desk stand. The LED control is active high (+5V DC) and TTL compatible, supporting seamless integration into automated systems.

Audio Performance and Filter Technology

To ensure clear vocal reproduction, the module incorporates an integral UniSteep filter. This filter provides steep low-frequency attenuation at 80 Hz with an 18 dB/octave slope, which improves sound pickup by removing unwanted ambient noise without compromising voice quality. The module operates with a 130-ohm impedance and requires 22-52V DC phantom power.

Durable Construction

The ES8766RC features heavy die-cast construction to withstand regular professional use. No-slip bottom pads minimize the coupling of surface vibrations to the microphone, ensuring stable audio capture. The unit utilizes a TB5M-type output connector for secure connectivity.
