The Bit-Perfect Test
Perhaps one of the most useful features of MSB DACs is the bit-perfect test. A series of files can be downloaded here. They are .wav test files that when played, will be identified by the MSB DAC and checked, and will be reported on the display if they are bit perfect. The message will stay on for a few seconds. If there is a problem with the test, the file will play and a loud burst of static like sound will be heard but the display will not indicate any change. The DAC IV, DAC IV Plus, DAC V, Analog DAC, and Select DAC support the Bit-Perfect test.
Warning! These files contain 0 db content. Turn your volume down before playing.

Keeping the Firmware Up to Date
Product firmware updates are free and offer both corrections of problems we found and performance improvements. We recommend keeping your Product Firmware up to date.
The first thing to do is to check your product to see if it needs an update. Go to the product below and check your version number. If it needs an update follow the instructions.
Saving the File
The first step is to download your file and save it on your computer. Each browser is a little different, but they all do the same thing. You will want to right-click on the link and select “Save link as…” or “Save target as…” or in Safari it is “Download Linked File.”
If you have a MSB Universal Media Transport, save the file on a USB memory stick like the one shown at the right. Insert the USB stick into the UMT. Select the Upgrade file and play it. You will hear a voice message with instructions. If the new firmware is installed correctly, this will be confirmed.
If you are playing the file from your computer, save the file on the computer. Select the Upgrade file and play it using iTunes, Foobar, or JRiver. You will hear a voice message with instructions. If the new firmware is installed correctly, this will be confirmed.
Instructions if you are burning an audio CD in iTunes
Once the file is saved, the second step is to create a playlist for the code files. A playlist will allow you to burn the files to a CD.
To make a playlist in iTunes, go to “File” and “New Playlist.” Name the playlist “update code” or a name of your choice.
The third step is to add your previously downloaded code file to the playlist. To do that, all you need to do is click and drag the file or files and drop them on your playlist name in iTunes. A blue box should appear around the playlist name.
After the playlist is created, insert a blank CD. In the bottom right corner, there is a button called, “Burn Disc.” After clicking that button, make sure it is set to “Audio CD” and that “Sound Check” is off. After the settings are correct, click “Burn.”
After you have burned your CD, play it in the Data CD IV, or another bit-perfect transport. You must use a S/PDIF interconnect to the CD Transport, either RCA, Balanced XLR or Optical to do the upgrade. Do not use the MSB Network or ProI2S for the upgrade. While these interfaces are bit-perfect, the update system was designed to default on updates to the S/PDIF interface. You will hear a voice message and listen to it’s instructions. If you hear “Update Failed” please try again and check your settings.
When do I need a Firmware update?
DAC firmware updates offer both corrections of problems we found and performance improvements. We recommend keeping your DAC Firmware up to date. You can check the current version of Firmware installed by following these steps:
- Press the menu button on the front panel (left button with square on it)
- Turn the volume knob until ABOUT is displayed
- Click the select button (right button with *)
- You will see CODE REV #
- Then you will see INPUT DSP REV # and FILTER DSP REV #
- The current version is 1.3, 1.1 and 1.1.
What to expect when doing the firmware update
This update includes three upgrades within the same file, the input DSP, digital filter DSP, and micro all together. The file is several minutes long. Please do not interrupt the process and let the file finish to the end. When you play the file you will hear some instructions, and three upgrade tones. Following each tone you will either hear silence for about 30 seconds (this varies) or you will hear the message ‘upgrade failed’. If all the upgrades fail, it is because you did not play the file bit-perfect. You may have computer upsampling on or digital volume control somewhere in your playback system. Contact MSB if you need help.
All DAC V

If you are having troubles with the USB and your Mac, please contact MSB. The USB interface is a plug-and-play device for OSx and requires no drivers.
The below is for PC Users Only! If you are using OSX you do not need to install drivers.
Checking your code version
To check your driver and firmware rev first open the USB Audio 2.0 Class Driver Control Panel. This program is always running, but is hidden in the task bar. First click on the “Show hidden icons” button. Next double-click on the blue “M” logo. Click on “Device 0” from the list on the left side. Look at the field under Device Info called “RevisionID:” That is your USB Device rev number.
For Windows 8 and 10 support, you will need to download the following files. The way to update your USB Interface is explained in the Windows 8 update instructions. In order to get the USB working with a Windows 8 computer you need the latest PC driver (3.20.0) and the latest device firmware (3.3.0).
The USB input will not work if you try to use the new driver with the old USB firmware. Both MUST be updated before tyring to play.
