Q: I'm looking at a new A/B receiver and would like to know what is the best way to handle a second pair of speakers, which we have in our kitchen. I will be setting up a surround system for the main speakers. Some receivers have an A/B speaker switch, but it seems like many mid- and higher-end receivers don't have this but have the pre-amp outputs. I don't want to add an amplifier for the second set of speakers. Should I just pick a receiver with the A/B switch? Get a separate A/B switch box (which seem kind of expensive, $100)?

A: A/B speaker switches were common on older stereo receivers, but are less common today. Modern surround receivers are designed to drive at least five speakers, which is quite a drain on a receiver's power supply.

You can purchase an inexpensive speaker selector (around $20) at Radio Shack and use it to switch between the main speakers and the speakers in your kitchen. You will not be able to listen in both rooms simultaneously, but you can switch the speakers to play in whatever room you are in.

If you spend a bit more for a higher-end receiver, you can get one with dual-zone controls. This will allow you to not only have speakers in the kitchen, but you will be able to listen to different sources in each room. For example, you can simultaneously listen to the radio in the living room and the CD player in the kitchen.

Q: My question is about a scratch in the protective cover on a 51-inch rear projection TV. Other than shell out about $200 for a new cover, are there an products I could try first, such as a polish or one of those gimmicks you see on TV that take out the scratches on your car?

-- GREG SAMIDE,

A: I do not know of any such scratch removers, but you could certainly try since you have to replace it anyway. If you are not concerned about the screen itself, you can remove the protective cover and you will probably have less glare and reflections.

I also would advise you to shop around. Parts prices are not always fixed, and a dealer may be willing to give you a discount.
