An Excellent Stereo Recording System

The R88 is a microphone system designed to simplify coincident stereo recording techniques. The microphone is clearly marked and easily configurable for Blumlein and M-S recording. According to AEA’s Matt Ashman, “Using two matched ribbon motors in a single convenient housing, engineers are more likely to do tracking in stereo, which makes for better mixes.”

The Large Ribbon Geometry™ bidirectional motor design unique to the R88 has an excellent off-axis frequency response. The R88 captures a faithful acoustic image of the instruments or ensemble placed in front of it, as well as a clear and convincing representation of the recording room. The microphone is shock mounted to a standard 5/8” female thread, and includes a locking angle adapter for flexible positioning.

The R88 is excellent on applications as diverse as drum overheads, brass, woodwinds, and chamber and orchestral recordings. The mic was designed to have a natural and realistic presentation, with balanced, neutral tone and precise imaging. The coincident configuration of the R88 means that postproduction techniques such as stereo rotation and width adjustment may be performed without comprimising the relative placement of instruments in the soundstage.

• Wide-band response from 20Hz to 20 KHz

How Is An R88 Different from Two R84’s in Stereo?

The R88’s LRGTM motor has been modified for improved off-axis frequency response and tonal purity. The design approach is minimalist, and the tonal quality can be described as an updated version of the “classic” ribbon sound. The R88 captures a sound that is accurate yet flattering to instruments and voice as well as free from harsh condenser diaphragm resonances and unnatural coloration. For the recording engineer who regularly records in stereo, we believe the R88 provides sonic excellence as well as a convenient alternative to multiple-mic arrangments.
