Analog DAC Users Manual Unique Product - a Preamp or a DAC? This product has the option to be a unique combination of a very high performance DAC and the ultimate passive preamp. It is intended to be used as both for the best possible sound in your CD, DVD-A system. Our preamp philosophy is based on the belief that from the moment analog audio is Phono Transport created, every transition that is made degrades the quality. That means that an active preamp with Preamp many stages if perfec

Loading New Firmware Loading custom Digital Filter Firmware will permanently change the operation of your DAC. MSB Technology can configure custom software for your DAC to meet virtually any requirement. Playing an audio file containing the new firmware will erase the current software in your DAC and replace it with the contents of the update file. This is safe if one precaution is faithfully observed. The firmware update process takes about 20-30 seconds and you MUST NOT INTERRUPT THE POWER

USB Input Module The USB Input is the most advanced MSB produces. The hardware is able to handle audio data and DSD up to 32 bit, 384 kHz. Apple MAC OS On the MAC the USB is plug and play. The MAC will recognize the USB DAC and its capabilities and will allow the output to be set to any sample rate desired. The bad news is, with certain programs such as iTunes, the output sample rate has to be set manually when the file sample rate changes. So if you set the output for 192kHz, and

Using the Analog DAC to test your source The Analog DAC is unique in that gives you a precise test for bit perfect playback. If you are playing a CD, a copy of a CD or a ripped CD file on your computer the DAC should be receiving the file bit-perfect and it it is not, your sound quality will be compromised. This corruption could be accidental. You may have ripped a CD with a program that does a conversion. This is very bad and you should not do this. You may have an upsampling transport

To install a new module, slide the new module into the track and push firmly into place. Now put the screws back into the base, put the screw back into the jackpanel of the module, and return the installation tool to its place on the base. Finished! 12
