MODEL SM33 SUPER CARDIOID

RIBBON MICROPHONE

U.S.

Patent

D-178,018

The ribbon element

the SM33 imparts a pleasantly warm charac-

teristic to the speaking voice, a feature which is especially desir-

able for announcing and narration applications. The same warmth

is also imparted to instrumental or vocal recordings. Because its

polar

pattern is somewhat more directional than a conventional

cardioid, the

SM33 provides superior separation in studio record-

ing

well

control of unwanted surrounding noise. Smooth,

wide range response. Unusually rugged. Two-position Selector

Switch

tailors bass frequency response. Self-adjusting lifetime

swivel-shock

mount permits tilting head 45° forward, 90°

back-

ward. The SM33 is very immune to mechanical noise, making it

ideal for desk

top

talk show applications. Cable entry from

underside keeps the cable from protruding toward the

cameras,

and protects it against bumps and jolts.
