Every microphone has a characteristic polar pattern that determines how well it
accepts or rejects signal coming from various areas around the microphone. For
example, omnidirectional mics accept all signals regardless of wherever those
signals originate (in front of the mic, behind it, to the side, etc.).
The R21S can be connected to any mixer, mixer/amplifier, or mic preamp using a
standard microphone cable. As shown in the wiring diagrams below, connect the
female XLR end directly to the R21S’s gold-plated connector and the other end
(normally a male XLR end, although some mixers use 1/4" connectors) to the
mixer, mixer/amplifier, or mic preamp.

The R21S can be mounted to any standard microphone stand (using the included
mic clip) or can be handheld; due to its unique mic element shock mounting, it
generates significantly less handling noise than most other microphones. If handheld,
take care not to cover the any part of the head grille with your hand. Be aware of a
phenomenon called the proximity effect which causes a noticeable increase in low
frequencies (bass response) when a microphone is close to the audio source. This
can have positive impact—for example, it will cause your voice to sound much fuller
when you sing close to the mic than when you sing at a distance. The R21S is spe-
cially designed to be used up close, since it provides a built-in windscreen for
removal of pops, sibilance and onstage noise. The key to developing the best mic
technique is experimentation, along with awareness of the general principle that,
the closer your R21S is to a signal source, the greater the bass response.
