The Avantone Cabernet (C-series) microphones are designed to offer true professional performance. They will meet or surpass the performance and specifications of much higher priced mics. The Avantone CV-28 is truly a gorgeous looking and sounding microphone. The design, character and performance is comparable to some of the fine vintage tube mics of the 1950’s & 1960’s, but at a fraction of their cost.

The rugged CV-28 microphone body and capsule assembly are precision machined of brass. Aesthetically, it features an elegant Cabernet Wine-Red finish, accented with polished nickel trim and grill. The transformer coupled tube circuitry offers a modern-day, affordable  solution to the desire to capture  the character of  famous European and American  vintage designs. Any studio can proudly offer the CV-28 as a primary acoustic instrument mic…It exudes class visually as well as sonically.

Manufactured using the finest materials yielding a very solid feel, superb structural integrity and rugged reliability. The versatile CV-28 mic is able to produce professional results with a warm, pleasing sonic character. The included Custom Retro Shockmount is superb in allowing a precise positioning of the mic while inhibiting the transfer of unwanted vibrations up into the mic. This isolation allows for superior professional results. Includes military-grade -15 dB pad & 80 Hz LF roll off switches.
