listen to. Music with less high
frequencies may benefit from the slow
roll-off filter.
To play a 24/192 disc the source player
needs to have an MSB Network
output. If your DVD-A player does
not have the MSB Network output, it
can be added. A 192k input will
override the upsampling settings.
Front Panel Controls
Frequency and Volume Display – The actual sampling frequency of the incoming signal is displayed. This is not the normal display of the
frequency reported by the decoder, which, for example, would always read 44.1 kHz even if the transport was playing at 44.3 kHz. The
MSB frequency counter displays actual frequency so don’t be surprised if some lower cost DVD transports fail to produce an accurate
playback speed.
The volume is displayed whenever the volume is adjusted. It is shown as attenuation in dB. At 0 dB, the volume control is disconnected
and the DAC works as if the feature was removed.
Upsample On – The incoming data is upsampled to 4 times the incoming rate, but limited to 192 kHz. This is a true upsampling, not a parallel
scheme as found in some DACs. The feature can be turned on or off.
Input Select – 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. In either case, active sources light up the input LED at half brightness, and the selected source at
full brightness.
Filter On - This feature adjusts the slope of the digital filter. This feature is very much related to the interpolation feature above. The
Platinum defaults to the gentle filter slope. In this case some of the image frequencies can be reflected into the audible range, but the
negative energy spread effect of filters is minimized. This setting is best for higher sampling rate sources such as 96K or 192K. For low
sampling rate sources the brick-wall filter may be desirable as image frequencies are more likely to affect the sound. Again, these rules-
of-thumb can be dramatically affected by your personal taste.
Phase Invert - This feature allows improperly recorded material to be corrected. The phase of the outputs is inverted digitally.
Volume Knob - This knob adjusts the volume between 0 dB and -62 dB. When the volume control module is removed, the knob becomes
an input selector. Our 0dB actually equates to a +6 dB of gain in relation to the industry standard 2 Vrms level.
Display Dim - Press and hold input on the front panel and press “mode” on the remote. The display is turned off. When changes are made,
the display will show them briefly. Repeat the function to turn the display back on or disconnect the power for a moment.
Remote Control
Mute – Mutes the analog outputs. Causes the display to flash the volume setting, even in the display dim mode.
Mode – Steps through the 6 inputs. This button also turns the display dim mode on and off if you press it when holding the front panel
input button in..
Volume up and down – Steps the volume up and down in 2 db steps.
4 square buttons – Controls for the CD player version of the product.
Batteries – The remote control uses two AAA batteries.
The same remote works with the Platinum CD player and the Platinum volume control. If using the DAC
II with a Platinum volume control, remove the volume modules from the DAC II so they will not
interfere with the operation of the Platinum volume control.
