While gobo isolation panels can be effective in isolating performers 
from each other, they introduce their own set of problems - including 
reflections close to the performers and/or microphones that result in 
comb-filter distortions. Because gobos usually are bulky and occupy 
valuable floor space, they also inhibit the ability of the musicians to 
hear and see each other easily. Such a setup requires complex and 
often cumbersome headphone monitor mixes for the musicians. 

Since the R84 is bidirectional, it exhibits nulls at right angles to the 
principal axis. These nulls produce a “plane of rejection” around the 
sides, top and bottom of the mic that can be used effectively to 
reduce leakage. Simply arrange the musicians so that nearby 
instruments are placed in the “null” of their neighbor’s microphone, 
and vice versa. Although this does not entirely eliminate the need for 
gobos, it can significantly reduce their number.

Keep in mind that a certain degree of bleed is not necessarily bad. 
For some styles and genres, it can, in fact, be beneficial to embrace a 
little bit of bleed in order to create cohesive and natural sounding 
recordings. The important thing to listen for is whether or not other 
instruments that bleed into a specific instrument microphone still 
sound natural. You will generally find that well-designed ribbon 
microphones like the R84 capture a natural off-axis sound, which 
means that bleed from other instruments can contribute to the 
overall sound in a pleasing way.

PROXIMITY EFFECT

Proximity effect, a 
characteristic of all 
directional 
microphones, is a rise 
in low-frequency 
response at closer 
working distances.
This can be used to 
superb effect, 
particularly with 
deeper vocals to 

to enhance richness and depth. A potential trade-off is reduced 
articulation resulting from the masking effect on the treble due to 
“excessive” bass boost.
