Sound and Speaker System

01/25/2017 10:26 PM

Hi,

(1) "Multizone selector with PA / sound mixer2 mic and 1 Auxiliary input cut type tone control" is used in sound and speaker system.

What is multi-zone selector and sound mixer2?

(2) What is a 16 channel power amplifier?

(3) What is "PA announce and music sound selector auto mode for pair to audio cable interconnection to fire alarming 4 loop panel".

(4) Why we need "CD, MP4, DVD, USB, cassette player/recorder of PA player 500 watts suitable for 230 volts AC and 12 VDC operation?"

(5) Why we need sheet metal enclosures and 6 way terminal connectors with sound and speaker system?

Regards,

Quit while you are only a little bit behind.

Consult a Design Engineer locally, as it is obvious that one is required.

This sounds like details from your customers commercial building sound system specification document put out for tender or order placement.

Rather than answering the individual questions I would suggest contacting a sound system supplier and get them to quote you directly.
