control is installed, for optimally matching the DAC output to a preamp input. Many preamps sound much better

dither greatly increases the perceived resolution of the audio without harming the music in any way. The dither
isgeneratedbyahighlyrandom,non-repeatingwhitenoisegeneratorandisthendigitallyltered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.
• •
Analog Input Volume Control - The analog input can either be volume controlled or bypass the volume control.

Power Supplies
The Analog DAC can be used with a range of power supplies. We produce a fully linear desktop power supply that ships with the DAC
or an upgraded power base. Both are voltage switch-able for 120V and 240V. Each uses a 5 mm x 5 Amp Fuse.
ALWAYS CHECK THE VOLTAGE SETTING BEFORE PLUGGING IN THE UNIT. IT MAY HAVE LAST BEEN TESTED AT
THE WRONG VOLTAGE. FAILURE TO SET THE VOLTAGE CORRECTLY MAY RESULT IN THE DESTRUCTION OF YOUR
POWER SUPPLY OR DAC.
In addition, the Analog DAC can be used with the DAC IV power bases.
