SOTR Accessory
Ops-Core SOTR Voice Projection Unit (VPU)
The Voice Projection Unit (VPU) is an optional add-on for the Ops-Core SOTR with Microphone, built to make sure your voice is heard when it matters most. It delivers clear, powerful voice projection in loud, fast-moving environments, helping teams stay coordinated and aware even without comms.
The VPU attaches quickly to the SOTR with a simple, tool-free design, making it easy to add or remove as mission needs shift. It connects directly to standard push-to-talk (PTT) devices using the SOTR's existing microphone port and integrates seamlessly with tactical headsets. This allows operators to move instantly between projecting their voice locally and switching to secure wired communications, all while maintaining respiratory protection.
Installation & Comms Routing
Prior to first use, the SOTR lock nut and filter gasket must be swapped with the provided VPU-compatible hardware. Once installed, simply align the VPU pins with the SOTR microphone receivers and engage the slide lock. To use a radio without local voice projection, simply rotate the VPU dial to the "OFF" position; your secure radio comms will continue to pass through seamlessly.
