Buy this combo package and save nearly $20 off the cost of purchasing and shipping these three items separately... All of our other MM phono preamp models provide the industry standard 38-40 dB of gain, more than enough if your moving magnet cartridge is typical. But what if your cartridge is NOT typical? A number of high-end MM cartridge models feature lower output as part of their quest for better sound. Until now, you had to either endure cranking your receiver or amp main volume waaay up, or face replacing your favorite cartridge (and maybe the turntable too) with something less desirable. Our TC-770LC changes the rules by providing up to 60dB total phono gain, more than enough to raise that soft-spoken cartridge up to the level needed to drive your amp or receiver properly. Our optional 1 amp regulated premium AC adaptor (twice the current of the standard adaptor) is also included... Looking for a simple and quick way to connect your turntable and preamp to your computer for recording or listening? It doesn't get easier than this. Simply plug the TC-770LC into our TC-ADUSB, connect its USB cable into your Mac or Windows computer, and go to it! Either analog port (one RCA, one 1/8" mini-plug) can be used for input; the second port provides a pass-thru signal to feed to your stereo receiver or amp, so you can listen thru your stereo and computer simultaneously. Unlike many other USB audio adaptors, the record level controls and meters in your audio editing software WILL work with ours. Our TC-ADUSB FAQ page has everything you need to get started digitizing your records to MP3 or CD-Rs.
