Thermionic Culture The Phoenix Stereo Mastering Plus Compressor

The Master Phoenix compressor is the latest iteration of the renowned Phoenix series, first introduced in 1998. The Master Phoenix, designed for mastering applications, offers a slightly gentler compression curve and 6dB lower gain compared to the standard version. It has gained popularity in studios and mastering suites worldwide, with notable users such as Ray Staff of AIR London Studios. The new Mastering Plus model features upgraded components, including precision switches and indented pots, for enhanced control and performance. It also incorporates Side Chain Bass Cut switches and a Standby mode for extended valve and component life. The unit utilizes high-quality Mullard and Siemens NOS valves for reduced noise and increased stability. With its improved features and accessibility, the Mastering Plus delivers exceptional sound quality and flexibility for mastering professionals.

Thermionic Culture The Phoenix Features:
