  • ISG123-P features Gain Control, while ISG23-P offers other trimmer combinations.
Technical Specifications:
  • Fitting range covers frequencies from 250 to 8000 Hz.
  • Acoustic Gain at 1600 Hz ranges from 35 dB to 52 dB.
  • Saturation Sound Pressure Level (SSPL) at 1600 Hz ranges from 110 dB SPL to 125 dB SPL.
  • Harmonic Distortion (THD) at various frequencies is minimal, with values like 1.4% at 500 Hz.
  • Equivalent Input Noise is 17 dB SPL, with a power consumption of 0.9 mA and a battery life of 100 hours using size 10 batteries.
Performance Measurements:
  • Full-on Gain and Reference Test Gain are specified, with maximum output (OSPL90) reaching up to 130 dB SPL.
  • Measurements are conducted according to IEC standards, with specific conditions outlined for accuracy.
Trimmer Controls:
  • Low Frequency Cut: Adjustable up to -30 dB at 500 Hz, affecting frequencies between 100 Hz and 3000 Hz.
  • High Frequency Cut: Adjustable up to -20 dB at 4000 Hz, used for feedback control.
