Know before you buy
The system is designed to be scalable, allowing you to daisy-chain or connect up to six ME-33 units to ensure full coverage in larger conference rooms.
No, the ME-33 utilizes a plug-in power system. It draws the necessary power directly from your recording device or computer through the 3.5mm connection.
Yes, the ME-33 features an omni-directional pickup pattern, which is specifically designed to capture audio from all directions. This makes it highly effective for recording multiple speakers around a conference table.
It is compatible with devices that support a 3.5mm mono mini plug and provide plug-in power. Please ensure your computer's microphone input is designed to supply the required 1.5V to 5V power.
The ME-33 is a boundary microphone, meaning it performs best when placed flat on a hard, stable surface like a conference table. The surface helps reflect sound into the capsule, which improves clarity and reduces phase interference.
While the microphone is sensitive enough to capture voices from across a room, its performance is optimized for meeting environments. For the clearest results in very large spaces, we recommend using multiple units to maintain consistent audio levels.
