I recently sold my Avia Guide To Home Theater DVD but I still have a virtually brand new Radio Shack Sound Level Meter that is used for calibrating your receiver and speakers. I am PayPal verified and have made several trades on DVDTAlK and a few here on the HTF. The cost to purchase this item is not set in stone and if a deal can be made via paypal, it will be shipped out tomorrow free of charge. **Sound Level Meter from Radio Shack is necessary when you want to configure your sound when using the Avia Guide To Home Theater.** $35.00 (Original Cost (40.00) SOLD!!
