The Rane RE 27 Realtime Equalizer is a single-channel, one-third octave equalizer and a single channel one-third octave realtime analyzer. Housed in a two rack-space unit, the RE 27 features long throw slide controls on each filter band ensuring good resolution over its boost/cut range of +12dB to -15dB.

The built-in realtime analyzer provides a visual indication of the amplitude characteristics of each one-third octave band and is designed to be used to flatten the response of a sound system with great ease.
