Operational Menu Options
The high level menu options have to do with operation settings. They are things that you may want to change on the fly as you listen to
different music or with different equipment. See the Menu tree for details.
Phase Invert
- Toggling the Phase Invert will change the absolute phase of the output. There are some recordings that “accidentally”
swap the phase. For those who are phase sensitive, we always include this option. The phase of the outputs is inverted digitally.
User Button
- Defines the function associated with the user button * on the front panel.
Remote User Buttons
- Defines the function associated with the remote user button 1, 2 and 3 on the remote control.
About
- Displays information about the unit including the version number, serial number, distributor, and year of manufacture.
Setup Menu Options
The second level menu options have to do with setup parameter - things you will only need to set once. In most cases you will not need
to change any of these settings. See the Menu tree for details.
Video Mode
- This very important feature of the DAC allow all jitter to be removed from the input source. Data is read into a memory
and then independently read out using a ultra stable clock. When enabled this option will completely replace the incoming clock with
an ultra low jitter internal clock. The DSP monitors the incoming sample frequency and detects standard sample rate signals, 44.1 kHz,
48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz, 352.8 kHz and 384 kHz. The on-board clock then completely replaces the incoming
clock. Other sampling frequencies use the incoming clock from the source. The DSP allocates a huge internal FIFO buffer (1/2 second
at 44.1) that stores the incoming audio to decouple the incoming and outgoing data streams. Long absolute digital silences in the music
stream, such as between tracks and during pauses, are selectively shortened or lengthened by the DSP to maintain data synchronization.
This results in a significant delay between the audio source and the analog audio. You will not normally notice this delay unless video is
synchronized to the audio. For this reason this feature may want to be turned off when watching video, or the video should be delayed.
While using the on-board clock some very long musical performances greater than one hour with no silences, pauses or track skips
may cause a buffer overflow when using a standard transport. This will sound like a small CD skip. You will probably never encounter
this case but if you do MSB can install a special ultra high accuracy clock in your transport or other audio source to totally eliminate
this possibility.
Display Brightness
- Adjustable from 1 to 15.
Display on/off
- When turned off, the display pops on for a bit any time anything is adjusted, then turns off again.
Restore Settings
- Puts settings back to factory default setting.
Startup Volume
- This is the volume setting that is set upon power up.
Maximum Volume
- This is the maximum volume setting that can be reached. Use this feature to protect your speakers.
Fine Volume Steps
- The Select volume modules allow half or quarter db steps to be inserted between the standard 1 db steps. In most
cases this level of resolution is not audible.
Input Setups
Analog Input Volume Control
- The analog input can either be volume controlled or bypass the volume control.
Alternate Analog Input Volume Control
- The alternate analog input can either be volume controlled or bypass the volume control if this
option is installed.
Switching Mode
- When the input selector is manually selected, either all inputs are available or just active inputs. With active inputs
selected, A/B testing is very quick and easy.
MSB Network Channel Select
- The MSB Network supports 4 stereo channels of audio. With this feature the DAC can be configured to
decode any of the 4 sets.
