    Amplified speaker for 712 phone

    3l3mn8r New Member

      12_phone speakerI have a customer with an Netvanta 7100 and a 712 phone that they use as a

      conference type phone.  I am trying to find out if there is some way I can

      connect an external speaker (amplified) to produce a louder conference.  The mic

      is fine but many around the table cannot hear the incoming callers over the

      speaker on the 712. Any ideas or suggestions is greatly appreciated.

          While it is certainly possible to open the phone and solder wires from the speaker to an external amplifier I would recommend against it. 


          High-quality speakerphones are a combination of electronic, acoustic, and mechanical engineering working together.  One of the key features of good performance is the reduction of coupling from the far-end caller back into the microphone(s).  An external amplifier and speaker will drastically alter the phase, direction, and level of the far-end caller as received by the microphone of the speakerphone, resulting in echo, feedback, and generally bad performance.


          Spend the bucks for a well-designed conference room phone such as the Polycom Soundstation 5000 or similar.
