Change the fuse - Remove the cover of the Platinum. Now the power supply must
be separated from the DAC. Each side panel is attached to both the top DAC part
and the lower Power supply part. Remove the screws from the lower Power
supply part. There are also screws between the two parts along the back edge.
On newer units, the circuit board has two notches along the back edge. These
notches line up with the threaded holes from the cover. Remove the screws that
can be found in each notch. Now separate the power supply part from the DAC
part.
Change the MSB Network Input and Channel Selection - The MSB Network
supports 4 stereo channels of 192k data at once. Any DAC can be configured to
decode any of these 4 channels. For example, when an upgraded DVD player is
playing a DTS music CD, one DAC can be configured to Channel 1 and will
receive the front channels. A second DAC can be attached to the same wire at the
same time and by selecting Channel 2 will receive and decode the rear channels.
The 3rd channel is for the front and sub channels if you want to use them. The 4th
channel is for future formats
which may come along. Move
the jumper located on the input
board as shown in the diagram
to select the channel. Because the Platinum has two 192 inputs, each can have any
channel selected.
An MSB Network output upgrade provides three identical connectors allowing three
DACs to be driven at once, each set up for a different channel. With the two inputs,
another possibility would be to hook both up to the same multichannel source. Set input
one for front and input 2 for rear and you could then toggle between front and rear using
the input select.
Change the MSB 16X Digital Filter Options - The switches to change digital filter
options can be seen on the digital filter board. Please read the section of this manual on
how to set these switches very carefully before making any changes.
