Get Optimum Performance from Your Phono Stage

Music Direct has commissioned a special phono-stage burn-in and enhancement CD from Granite Audio. This new CD has specially recorded tracks to help you burn-in your new phono preamp and enhance the phono stage you have been listening to for years! Tracks on this disc were recorded with the RIAA Frequency Curve at 4mV for MM and .7mV for MC stages. Just plug your CD player's interconnect into you phono preamp, set the MM or MC break-in/enhancement tracks on repeat and save yourself many hours of tedious burn-in time. Greatly improves the sound of older phono stages as well. You must hear the improvement to believe the difference!

Using this CD to burn-in your phono section will save needless wear on your record stylus and turntable. Standard music CDs cannot be used for this purpose because their signal level at 240mv to as much as 4 volts would overload your phono inputs, which are designed to handle only about 4mv of input signal. Also, conventional CD's would have their low frequencies boosted by 20dB more than a phonograph record that was encoded with the RIAA bass rolloff. So, playing a standard music CD through your phono input could also damage your speakers with excessive bass tones. DO NOT attempt to play any standard music CD's through your phono inputs. You can only do this with the Granite Audio Model #CD-101 Phono Burn-In CD. Our CD is the only one that has been engineered for this purpose.

Test CD produced by Don Hoglund of Granite Audio using Hewlett-Packard random noise generator, HP decibel meters, Tektronix ultra-low distortion audio signal generator, Tek digital frequency counter, Tek digital decibel meters, and Tascam Pro-Studio CDRW. This test CD is not engineered for human consumption. Don't actually listen to it. It is meant to burn-in the phono section while you're not listening to it. Some of the RIAA test tones are recorded more than 70dB below reference and therefor the SN ratio is also very low. Do not play this CD through other inputs because the RIAA high frequencies are 20 dB louder than the reference frequencies when not played through the RIAA equalization circuit of the phono input and can damage your tweeters or hearing.

Use Track 33 to burn in your moving coil phono stage. Put your CD player on Track 33, single track repeat, and only play Track 33 repeatedly. Tracks 1 through 32 will also burn in your MC phono stage, but will do so at a higher voltage level that is equivalent to the output of a Moving Magnet cartridge.
