Model ST250 is a sophisticated 2-line amplified business speakerphone that can digitally adjust frequency-specific volume levels so that any user, especially those exposed to harsh 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 50 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.
The internal acoustic chamber also restores low-frequency components in the incoming voice signal, allowing the speakerphone to deliver a crisp acoustic experience one would have only expected from a high-end conference speakerphone.
The huge 7.4 square inch display allows a user to read the screen comfortably even from a distance. This phone also features a quick and easy way for busy user to stay in touch - even out of the office. With a touch of a button, incoming calls can be set to be forwarded to a mobile phone.
