Stereo Ribbon Microphone 
There is no easier way to track natural stereo than by using a stereo mic. The natural sound stage and character of R88 Series' Blumlein imaging makes it a great microphone for producing an authentic representation of a performance in its environment. Known as the “set it and forget it mic,” using an R88 is an excellent way to effortlessly capture the authentic and natural sound without the hassle of a multi-mic setup. From drum overheads and live concert recordings, to horn and strings sections, the R88’s Blumlein system is convenient to use and delivers a phase-coherent, accurate transient response. With sense of depth, the R88 puts the listener right with the performers in the recording room.
