APPLICATIONS

The versatile TG I55c helix condenser microphone really
demonstrates its strengths when used in combination with the
violin, viola, recorder, dulcimer, fretted stringed instruments or
zither, cello, double bass and many other instruments. It delivers
extremely natural, true sound reproduction without colouration due
to the missing of the proximity effect. The omni-directional polar
pattern ensures even sound – regardless of how the capsule is
positioned. A further advantage is the unique, innovate clamp that
enables quick and easy mounting – without drilling holes and
without scratching the instrument.

FEATURES

• High performance miniature condenser microphone
(omnidirectional)

• Versatile possibilities to attach the helix holder

• Natural reproduction

• Absolute studio quality

• Unobtrusive design

• Light weight, the balance of the instrument is maintained

• 4-pin female mini XLR connector
