Remove the cover of the Platinum. Work on a soft scratch resistant surface like a carpeted floor. Three screws are located along the back

edge and three screws on the bottom along the front edge. With these screws out, the cover lifts off. 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.

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.

Quality Check

Each Platinum is comprehensively tested and the actual outputs measured. A test plot should be included in your Platinum like the one

below. Just a few comments on the test plot. Most measurement systems cannot measure as low a level as -145 db. That is the noise floor

of our test system which means the Platinum may measure better, but we cannot see it. The rise at low frequencies is always present on our

test setup and the right channel always shows a little more noise than the left (the right cable runs closer to the digital input cable). The

test date is also always off.
