Public Address System

There is no need of very hi-fi sound system for public address. some time people select stereo/surround sound/5.1 for small auditorium which is of no advantage and expensive.
I select following sound system for 50 feet x 50 feet x 15 feet height Hall ( Gypsum celling for acoustic purpose). 120 students sitting Capacity.
1. 120W Amplifier (Ahuja Make) 5 + 2 Aux in.
2. 32W x 4 Nos of speakers.
3. Wireless Microphone.

Speaker should face opposite Microphone direction otherwise echo effect.

Debain 4.0 boot problem with XP dual boot

Debain 4.o with Xp dual boot: Sometime after shutdown Xp and than boot with linux give ACPI exception errors like AE_NOT_FOUND or Searching for Mountpoint without activity.

Mostly Linux with DHCP enable trying for IP Address and Latest Motherboard onboard Lan Card can not initialize in Linux. It easily up under Xp. You can see link disconnection in your Lan Switch or onboard Lan LED.Your linux has to take IP from mostly with your ADSL Modem/Router so it fails to get IP and ends with error/loop.

To come out from this problem do not think in a big way just Power off (computer,ADSL Router and switch) from Main and restart everything will work fine.Check lan connectivity on switch before boot.
