"Istok-Audio" is the largest manufacturer of personal rehabilitation devices for hearing impaired and deaf people, sound amplifying equipment for special facilities and rehabilitation devices for professional and everyday adaptation of hearing impaired people.

 _312Santa T — the first series of domestic digital trimmer hearing instruments (H.A.).Digital trimmers H.A. combine advantages of digital technologies and indisputable benefits in fitting traditional. Hearing instruments Santa T-112 and T-122 are designed for fitting 2d and 3rd degrees of hearing loss, Santa T-212 and T-222 are designed for fitting 3rd and 4th degrees of hearing loss with adults and children including a pronounced recruitment.Possessing great flexibility, the instruments can be quickly and precisely fitted to meet requirements of the users with the help of 4 controlstrimmers without application of any special equipment.Method of fitting and adjustment is acceptable both for professionals, who are familiar with the computer aided selection and fitting of programmable and digital hearing instruments and for those, who has only experience in application with analogue instruments.

Santa T 312 super power digital hearing instrument with trimmer controls. It is designed for electroacoustic correction by air conduction for severe and profound hearing loss, including recruitment.

Functions and advantages (Santa T-112, T-212, T-312):

  • 1-channel digital compression of full dynamic range (FDRC) with adjustmentof the threshold attack and release for low level input signals (AGC for input);
  • Broad band agc-0 with adjustment of the threshold, attack a relies time for compression;
  • Double compression noise and low level environmental noise reduction (expansion);
  • Active L.F and H.F filters with deep control;
  • Sound (beep) low battery indicator and microphone-telephone (M-T) switch;
  • O-T-M switch;
  • Input agc1 (yellow);
  • Output agc0 (red);
  • Low frequency tone control (blue);
  • High frequency tone control (green).

Functions and advantages (Santa T-122, T-222):

  • Two (2) channel compression of the full dynamic range (FDRC) with a separate adjustment of the knee point, attack and release time for low level input signalsin the low frequency (L.F) and high frequency (H.F) channel. The control in the L.F channel allows to bring the patient’s own voice perception up toa comfortable level;
  • Broad band output AGC–0 with adjustment of the knee point (threshold), attack and release time;
  • Double compression (fast & slow);
  • System of microphone noise and low level environmental noise (expansion) reduction;
  • Active L.F filter;
  • Acoustic (beep) indicator of low battery and switching over microphone/telephone modes.
  • O-T-M switch;
  • AGC1 in the first channel input (yellow)
  • AGC2 in the second channel input (orange);
  • AGC0 output (red);
  • Low frequency tone (blue).
