    Fanstel ST50

    The ST50 is a sophisticated amplified speakerphone that can digitally adjust frequency-specific volume levels so that any user, especially those working in extremely noisy environments, can comfortably and clearly hear a caller’s voice. It boasts highly flexible sound settings: incoming voices may be amplified by up to 52 dB with extra amplification for high frequencies. This level of amplification has been tuned to more effectively restore the perception of many phonemic distinctions common in speech than competing models.

    As a convenience, personal volume amplification settings are automatically saved for later recall. Additionally, caller names and numbers are easily visible on the large 7.4 square inch backlit LCD display.
