ICOM Desktop microphone for IP501M SM28

Desktop Operation for the IP501M

The SM-28 provides a desk-based speaking and listening position for the ICOM IP501M. It allows an operator to communicate without repeatedly handling the radio’s standard microphone, making it practical for dispatchers and staff who remain at a workstation for extended periods.

Common applications include:

Dispatch and coordination desks Security and facility operations Fleet management offices Remote-site communication stations Emergency and backup communication positions

Directional Microphone

The SM-28 uses a unidirectional dynamic microphone that is designed to pick up the operator’s voice primarily from the front. This helps reduce unwanted sound reaching the microphone from other directions in busy offices and control rooms.

Built-In Preamplifier and Controls

A built-in preamplifier supports the microphone’s audio output, while the large desktop controls are designed for straightforward operation. The microphone also includes a monitor button for supported radio functions.

Stable Desktop Design

The SM-28 weighs 380 g and has a broad desktop base that helps it remain stable during push-to-talk operation. Its attached 300 mm cable keeps the radio connection compact in a desk or control-station installation.
