The TG I51 is a perfect combination of powerful and balanced sound with the capability to perform in live situations. This makes the well designed microphone the first choice for a wide range of applications. Snare Drums, Low Toms, Guitar Amplifiers or Brass Instruments. The dynamic TG I51instrument microphone shows extraordinary feedback suppression even on the loudest rock and roll stages. The cardioid pattern ensures high attenuation of ambient noise and high gain before feedback. This makes the microphone especially suited for close-miking in loud environments.
