The versatility of the C 1000 S makes this an extremely popular model, and one ideally suited for all kinds of recording and live sound applications. If no phantom power is available, the mic can be powered by a standard 9 V battery, making it perfect for mobile use. With its new battery monitoring electronics, the C 1000 S now features a reliable LED warning light. The red LED above the the microphone switch lights up when the remaining battery life falls below 45 minutes. The polar pattern can quickly be switched from cardioid to hypercardioid simply by attaching the PPC 1000 Polar Pattern Converter provided to the microphone capsule. The PB 1000 Presence Boost Adapter also supplied with the C 1000 S adds 3 to 5 dB of high-end enhancement between 5 and 9 kHz, improving clarity of speech and adding definition to instrument sounds.
