Most Shure unidirectional microphones are designed with a bass response
that provides control a t low frequencies yet still allows proximity effect to be
used advantageously when desired. To employ proximity effect, you need t o
hear the amplified result. Just as you practice your instrument, you w~ll want
t o practice your microphone technique t o get the precise sound you want. [A
good way t o hear the actual result of proximity effect is t o use monitor
speakers or headphones if they are available.]
Omnidirectional microphones do not exhibit proximity effect when used
closeup. Because the response does not change with angle or distance from
the performer, an omnidirectional microphone is valuable when the sound
must stay the same for several performers positioned around the
microphone, or for a performer who moves from place to place during a play
or ~nterview. But be aware of feedback problems that may occur if omnidirec-
tional microphones are used when sound amplification is present.
CHOOSING A MICROPHONE EXTENSION CABLE
Low-impedance microphones can be used with practically unlimited lengths
of cable with no added noise or high-frequency loss. Any Shure 2-conductor
balanced cables [e.g., C25B. C25E, C25F, C50F, C1 OOF, or C20H] can be
used as extension cables for Shure low-impedance microphones. These
cables can also be used in any required lengths or combinations between a
low-impedance microphone and the C25G Low-to-High-Impedance Cable-
Transformer or between the microphone and an A95UF Matching
Transformer.
High-impedance microphone cables are usually limited t o 6 . I m [ 2 0 f t ] t o
avoid high-frequency loss or possible noise pickup. If longer cables are needed
with high-impedance microphones, use such Shure cables as the C256,
C25E. C25F or C20H t o reach the required distance. Then add the C20A t o
plug into the equipment. Adjust the treble control on the equipment to com-
pensate for the high-frequency rolloff caused by the extra length of cable.
Look for the Shure Audio Connection'" for quality microphone cables.
