Connect a microphone directly to Valcom one-way amplified speakers with the V-9939C, a microphone adapter that opens mic-level input access on speaker models that do not include it natively. The Telecom Spot Expert Review Valcom's one-way amplified speakers are designed for paging system input, but the V-9939C adds a path for a direct microphone connection — useful in spaces where a live presenter or announcer needs to speak through the local speaker without routing audio through the main paging system. A simple, targeted solution for conference rooms, break areas, and small venue installations.
