Varizone is a fully digital public address system technology developed and produced and by Klotz Digital. Other than traditional analogue public address systems Varizone has next to the analogue 70/100 volt speaker system solution also a fully digital solution that transmits the audio digitally to the speaker, where it is amplified by small, distributed programmable amplifier modules. This allows to combine Voice Evacuation System features with digital Public address, Intercom, and Background music functionality by adjusting the volume for each speaker individually depending on the application. == Technology == A completely digital bus structure distributes uncompressed digital audio data without any audible latency from one or many play-out stations to an unlimited number of locally amplified loudspeakers using either CAT5 or J-Y(ST)Y wires. The same bus supplies all active bus components with electrical power (e.g. powered amplifier modules (I-PAM), push button modules and noise sensing modules) and makes the need for additional external power supplies redundant. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Varizone」の詳細全文を読む スポンサード リンク
