XTERNAL MICROPHONE SELECTION

ii3 supports high quality voiceband audio. Integrated AGC amplifiers

support a wide range of microphone inputs and low cost electret

microphones ($3usd) will have similar intelligibility as expensive

"professional" microphones ($10-$50usd). Microphones mounted

externally should be in a vibration and moisture free environment.

XTERNAL SPEAKER CONNECTIONS

A 3.5mm Audio Out jack is provided for headphones, external

speaker or an amplifier. When connecting speakers to the Audio

Out jack, user an external amplifier or powered speakers

ETWORK WIRING USING

standard Straight Through wiring, similar to PC connections and

cabling changes are needed under normal operating

environments.

CONNECTION (Server/Client) or when using a PC to single ii3

intercom WITHOUT a hub/switch interconnect.
