Dither on/off
- With the dither activated the MSB Digital Filter continuously adds a tiny amount (-110 db) of random ultrasonic dither to
the Output. We have found through extensive listening tests that this tiny amount of dither greatly increases the perceived resolution of
the audio without harming the music in any way. The dither is added separately in common mode to the positive and negative DACs
in the Platinum and mostly cancels itself on playback helping to linearize the DACs. The dither is generated by a highly random, non-
repeating white noise generator and is then digitally filtered to remove all dither content close to the audio band. All of the dither between
0 Hz and 40 kHz is removed. Unlike some noise shaping algorithms like DSD the very low level of the ultrasonic dither involved should
never cause system high frequency related problems. MSB highly recommends that you keep the dither enabled. Dither can be turned
off when using our incredibly precise DAC for making measurements.
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 basic DAC IV volume module has 2 db steps and this feature is not available. With the Signature and Diamond
volume modules, this feature 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.
