Product Description

Infuse your recordings with the lush, classic sound of a rare, vintage mic using the extraordinary Sputnik vacuum tube microphone from M-Audio.

Equipped with a military-grade vacuum tube, Sputnik delivers an open, ultra-clean, and uncolored sound. This 6205M pentode tube is wired as a triode and features an inverted, socket less mount for improved audio integrity. Inside, the evaporated-gold diaphragm captures every detail. The head amp offers superior transient response and can be pushed to exhibit graceful overload characteristics.

Three selectable polar patterns and a tuned brass back plate allow Sputnik to provide outstanding performance in any application. Tailor the response to match your needs using the switchable 10 dB pad and 80 Hz high-pass filter.

This premium package comes complete with a dedicated power supply and seven-pin cable, shock mount, soft bag, and custom flight case.
