*Notes:
1. Gain and output depend on the earphone that is used. These specifications apply when
the Companion Mics system is used with the supplied 6i Isolator
™
earphones.
2. Maximum output is measured into a 2cc coupler with 90 dB SPL input.
3. Technical note for audiologists: When a hearing aid microphone is moved from the ear of
the listener to a position a few inches below the talker’s mouth, an increase of 16-20 dB SPL
is obtained. Insertion gain refers to the increase in ear canal SPL provided by the
Companion Mics system compared to listening directly to a talker one meter in front
of the listener.
