TOA BS-680FC 94dB sound pressure
|Sound pressure level [dB] at rated power (1kHz, 1m)||80..100|
The BS-680FC speakers have a strong, all-metal body, and are ideally suited for emergency broadcasting (voice alarm system) applications. The 6" (16cm) double cone speaker unit ensures high-quality sound. They can be quickly and easily installed in either a horizontal or a vertical orientation. Either concealed in-wall wiring or exposed wiring can be used for speaker cable connection. The BS-680FC provides two ceramic screw terminal blocks (1 cable to 1 connection type) allow bridge connection. The selectable input impedance can be easily adjusted by changing the top position of the unit’s transformer. Both wall and in-wall mounting are possible. The innovative structural design permits direct wall stud installation with screws.
