Optional Accessories
(speakerphone models with
microphone and speaker jacks)
The speakerphone version of the modem is equipped with
microphone and speaker jacks for use with headset, speakers and
microphone. (See installation instructions: p.16-17.) The handset
can be used to record outbound messages. However, a
microphone is recommended for better quality recordings. You
may use a combination headphone and microphone or a separate
microphone and speaker(s).
Microphone Requirements:
The microphone element must be of the electret type also known
(incorrectly) as a condenser type. The microphone in most telephone
handsets is of this type. This modem was designed for a microphone
sensitivity of -64 dBspl. Other microphone sensitivities work equally
well, with only a subjective difference in loudness. Carbon
microphone elements will also work, but don’t offer the quality of the
electret. Another common microphone element is the dynamic type
which will NOT work with this modem.
Speaker Requirements:
You can attach the modem to a high-quality amplified external
speaker or the earpiece of a handset. The external speaker must have
an impedance rating of 8 ohms or more.
