BLS-3502C/D Digital wired conference system
Function:
Controller: BLS-350M
*The panel adopts buttons to control speaking mode and the number of speakers, breaking the traditional dial control.
*LED displays working mode and allowed speaking number.
*The number of speakers: 1, 3,6 and full opening( 4 forms can be chosen)
*6 meeting work modes: chairman mode/first in first out mode/last in first out mode/LIMIT mode /FREE mode/responder mode
*The host can connect 60 microphone units, it divide into 4 parallel outputs, each channel can connect 20 units. It also able to connect expansion unit number of extended machine up to 5000 units by power extended machine BLS-350HD(under 255 units) or data extended machine BLS-350HS(above 255 units).
*Equipped with audio parallel output and a 6.3 jack output, conference recording outputs and background music inputs interface.
Chairman unit: BLS-3502C
*Latest digital design.
*With microphone ,speaking button and indicator lamp that can show and control the state of speech.
*Whole metal microphone shell .
*With a microphone unit connecting cable.
*Single projection; With Anti-gas sonic boom and wind shield.
*With Chairman priority key;could shut all the delegate unit.
*The chairman unit can be placed in any position in loop.
*The chairman unit is unrestricted by the limiting function.
*The chairman unit quantity is unrestricted in the loop.
*High sensitivity microphone.
*The power for units is supplied by the master controller at 9 safe voltage.
*Hand-in-hand connection method.
*With a microphone unit connecting cable 2.1m, 8P core line, convenient installation can increase efficiency.
