Sony HT IV 300

[SELVARAJ]

Hi,
I'm new to this music world.
I'm having SAMSUNG EH6030, SONY HT IV 300 & SAMSUNG BD F5500.
I would like to protect these from power fluctuations.
Can answer me the following questions?
1. Which stabilizer would be best?
2. Can I use single stabilizer for all above simultaneously?

Thanks in advance.
