Explicação, anotação:Air conduction. For indemnification of heavy and deep losses
hearing particularly in low-frequency region, smooth, îáðàòíîíèñõîäÿùåãî and
ëåâîóãëîâîãî types.
Descrição porminorizada da marca:Characteristic properties:
- the unique combination of large telephone and strengthening of dog gives
the volume, necessary for submission of high gain level of low frequencies
with minimal distortions;
- choice of additional microphone, excluding the emergence of back
relation, apparata they is better to compensate the hearing loss on low
frequencies, at the expense of probability reduction of self-excitation in case of strong the whisker
èëåíèè allows to. This is important in case of child prosthetic appliance;
- availability of àóäèîâõîäà. |
has following adjustments:
- A-GRAM controller (low frequency timbre)
- pc (PC) ïèê-êëèïïèðîâàíèÿ controller
- AGC (antenna array) the controller
- the ÌÒ-Ì switch
- the Ì-Ò-Î switch
- the gain control
