The R84 delivers balanced a treble/bass ratio at distances greater than some might expect; from as far as 15 feet away, the R84 will still retain its characteristic low-end. This is an effective application for the R84, as it allows the mic to breathe in the massive spread of sound that fills and interacts with a large space.

Blending With a Dynamic
A popular close-mic application of the R84 involves blending its signal with a dynamic mic to gain a high-end bite in the mix. Place the R84 2 inches from the speaker’s center and align a dynamic microphone adjacent, remembering to correct phase between the two microphones before tracking.
Some engineers choose to treat the compound signals from the two mics as one by panning them together. Others opt for hard panning both mics to their own ends of the mix, a method that adds dimension and depth to an electric guitar tone.
Sample delaying one of the two microphones by roughly 20 to 50 milliseconds gives the impression of a larger room, achieving greater depth in a mix. Remember to ensure that the sample delay is short enough to avoid phase issues.
