Front Panel Controls

Although the user interface is very simple and easy to use, in depth menus allow complete control of the DAC.

Menu Button  

– The square button is single purpose. It will enter the setup mode at the top of the menu tree.  If in the setup, 

and it doesn’t matter where, this button will exit the setup and return to the normal operational mode.

Input Selection 

– Each of the six  inputs can be selected manually, or the auto mode can be selected.  The auto mode is an automatic 

priority switching with auto signal detection.  The right and left arrows switch inputs.  If the AUTO input is selected, the unit will 

automatically switch inputs based on a priority (from left to right - Analog = lowest priority, MSB 2 = highest 

priority).  When a source with a higher priority becomes active, the unit will automatically switch to the new 

higher priority input.  Toggling through the inputs manually will defeat any auto switching. When 

in the setup menu the arrows move right and left through the menu structure. 

User Select Button 

- The star button is user defined.  In the default configuration, it does 

phase invert.  In the setup menu it can be changed to turn upsampling or reclocking On/

Off, or to select the digital filter, upsampler algorithm.

Input/Volume Knob 

- The large knob will select between inputs if the volume control option is not 

installed.  The right and left arrow  buttons on the front of the unit will also switch between inputs.   

When the volume control module is installed, the knob becomes the volume control.  This knob 

adjusts the volume b9 dB and -69 dB.    Our 0 dB actually equates to a 2.62 V rms output, 

just a little high in relation to the industry standard 2 Vrms level. 

Display 

- The display shows the Input in the upper left.  The lower left shows the input sample rate 

and bit depth.  The right shows the volume.

Remote

The MSB remote can be used to operate several MSB products.  The top half is primary for the 

transport.  The center is for the DAC and the lower part for the iLink. 

Power 

– The power button turns on and off the Power Base when the optional front controls have been installed.  

If your Platinum Power Base does not have a switch on the front, this button will do nothing.  When the power 

base is linked to the Amplifiers and any other MSB products, this button will turn off the entire system. (see 

power base manual for details)

Data CD IV controls 

– .  The keypad, stop and repeat buttons are for the DATA CD IV transport and have no 

effect on the DAC IV. 

Volume up and down 

– The center block of the remote has several functions.  The volume up and down buttons 

change the system remote if the optional volume controls are installed in the DAC.  Steps sizes are shown on 

the DAC display.  The mute button instantly mutes the audio if the volume option is installed.

< > = * and # buttons 

– These central buttons are also for controlling the DATA CD IV transport, but also can 

be used for navigation of the DAC IV menus.  See MENU below.

Input 

– This button toggles directly through the inputs of the DAC IV even if the DAC is set to the auto mode.

Menu 

– This is equivalent to pressing the menu button on the front panel and puts the DAC IV into the menu/

setup mode.  The menus can navigated from the front panel or using the < >, volume up/down  buttons on the 

remote as left, right, up and down.

1, 2, 3 

– These are user defined buttons.  They can be programmed in the setup menu to execute any function 

you wish from the following options.

Phase Invert - Toggles phase invert on and off.

Upsampling - Toggles Upsampling on and off.

Reclocking - Toggles reclocking on and off.  This is especially useful for watching movies, where 

reclocking may cause an objectionable audio delay.

Digital Filter Select - Toggles through the installed digital filters.

Upsampler Select - Toggles through the installed upsamplers.

iLink Controls 

– Provides basic iPod controls when this option is installed.

Batteries 

– The remote control requires two CR2025 Lithium batteries.
