Electro-Voice CO9 - Cardioid Dynamic Vocal Microphone with Midrange Boost and Slight Bass Cut

The Electro-Voice CO9 ( Cobalt Series) is a cardioid dynamic handheld microphone designed for live vocals, rehearsals, houses of worship, and rentals. Its response is fine-tuned with a slight low-end roll-off and midrange boost for clarity and intelligibility without harsh EQ. The neodymium magnet dynamic driver delivers healthy output and defined transients, while the cardioid pattern helps improve gain-before-feedback and isolates your vocals from ambient sound. The zamak (die-cast zinc) body and Cobalt finish are built to withstand heavy use. It connects via a 3-pin XLR and does not require phantom power.
