DAC Output - This unique feature adjusts the output of the DAC digitally. It is especially useful when no volume

 

 

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

 

 

 

 

with a lower level signal. With MSB volume modules installed this setting should be left at 0 db.

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.

 

 

 

 

 

 

Dither on/off - With the dither activated the MSB Digital Filter continuously adds a tiny amount (-110db) 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 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.

 

 

 

 

 

 

 

 

 

 

 

Analog Input Volume Control - The analog input can either be volume controlled or bypass the volume control.

 

 

 

 

 

 

 

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.

 

 

 

 

 

 

 

 

 

 

 

Note: The complete RS-232 command table can be found under the support tab on the MSB website.

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.
