ORBC AV installation continues

Over the last two weeks we made some minor modifications to our design and equipment list to reduce the number of power points the church would need. We originally incorporated some Extron compact amplifiers for each room’s speakers, but we reduced the number of amps in order to not need so many plugs throughout the building. We designed the placement of the amps strategically for easiest access and lowest intrusion. We’re utilizing Audiosource AMP 100 models throughout the building. These amps have a great feature that automatically powers them off when there is no signal, saving energy and maximizing the life of the amps.

Along with some re-design, we installed lots of speakers and wall plates, ran lots of CAT5 and speaker cable, and tested out our nifty Network Sound audio distributor. This device converts multiple audio signals to digital and transports them via twisted pair cable. The transmitter is a standard-sized wall plate that has RCA inputs. Shown here...
The receiving unit is a small box with a digital display and remote control, allowing you to choose which of six outputs you want to send the sound to.
With up to six inputs available on this model, any audio source can be sent to any zone. Thanks to Barani at Network Sound for providing us with this great solution.

We got the four speakers installed in the fellowship hall and tested the acoustics of the room. We’ve decided to modify our design again slightly to correct for some of the echo in the room making the audio more intelligible. Instead of having two speakers in each overflow room, we’ll have one in each in different locations from the original plan. They’ll be ceiling mounted near the corners of the rooms as opposed to wall mounted on one side.

The Draper motorized screen and projector mount for the fellowship hall arrived this week, so we’ll be installing those next week.
