Scott says that a preamp is really the brains of the system. An AV Receiver is a preamp with additional amplifiers built in. The preamp does all the work to decode the digital audio and send it out to the speakers. It can also simulate an acoustic environment. So it's pretty important.
Robert is an aspiring filmmaker and he uses a DSLR to make his films. He's planning to upgrade to a better platform, but wants to know how he can improve his audio. Leo suggests Beachtek. They make devices that will allow him to run real XLR microphones into his camera's minijack and take advantage of better preamps as well. That's the best place to start.
Scott has a few questions today. One is from a home theater fan who bought his components separately. The problem is that his Lexicon PrePro preamp doesn't have HDMI. So he's thinking of upgrading to a Marantz AV7005. Scott says it's a very good choice.
Duke wants to be able to rip his LPs and burn them to CDs. His turntable is a good one, but he doesn't know how to get it into the computer. Leo says that turntables are unbalanced. He'd need a preamp with a turntable connection. He should turn the amp on the turntable setting and then connect the amp into the computer, which has a minijack in, which would require an adapter.
