BTE ELECTRONIC HEARING AID | RITM
RETRO A1 is an analogue BTE hearing aid with an average frequency range; it is suitable to compensate moderate and severe hearing loss with horizontal and gradually downward-sloping audiometric patterns and with recruitment (sound perception impairment caused by sensorineural hearing loss).
FUNCTIONS AND ADVANTAGES:
- Manual amplification control;
- Low frequency tone control is smoothly conducted by the trimmer “N-H”;
- AGC acts as a distortion-free means of limiting output;
- AGC compression ratio is smoothly controlled by the trimmer “CR”
- Induction coil allows making telephone calls;
- Customary M-T-O mode selector combined with an on/off switch:
M – basic mode, enables the microphone and its acoustic amplification (speech, music and other sounds);
T – enables the induction coil for telephone calls and using the induction coil as a connector;
O – switches off the device; - Compatible with cell phones, computers, etc. via Bluetooth devices with a hearing loop.
