ISP in Idaho

We just finished doing an install of a pair of ISP HDM 115 speakers in the All Saints Presbyterian Church in Boise, Idaho. We had to create special brackets for the beams in the sanctuary. As you can see from the pictures, the beams have different angles from one side to the other. Here is a picture with the old speakers (Mackie SRM 450) and what it looks like now.

Well here we are all finished with the install. We moved some of the equipment we replaced (with the new equipment) downstairs to a multifunction room. Put it all in a rack (see above pics) We also brought a feed down from the sanctuary so they could use this room as an overflow. Read More...

Microphones Response to Sound
In contrast to the human hearing system, a microphone is a crude and simple device used to pick up sound vibrations. Actually a microphone only contains one faction of the human hearing mechanism, just a diaphragm which converts sound vibrations to electrical energy. Read More...
