Specifications

Power Supplies
Each function within the Platinum is provided with its own separate power supply. There are 5
power supplies in the digital portion and 6 in the analog. The power supplies in the digital
section ensure the maximum jitter reduction while the 3 power supplies for each of the left and
right DACs allow for the greatest channel separation possible. The
analog power supplies are the original high-speed discrete supplies
used in MSB audio products for over 13 years. The Platinum includes
a built-in P1000 Power Base, with its high performance triple wound
toroidal transformer and rectification. It can be configured internally for 120V or 240V and has a
detachable cord. Also provided is extra DC output that can be used to power another MSB
product like a volume control. The DIN connector next to the AC power connector is an auxiliary
output, not an input. MSB will supply a DIN to DIN cable upon request.
Voltage Conversion and Changing Fuses
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. Older Platinums may not have
notches. In that case the main circuit board must be removed to gain access to these screws. Now separate the power
supply part from the DAC part.
The Platinum can be configured for 120V or 240V operation by changing the location of two fuses internally. For 100 to
120 Volt countries, fuses are placed in F2 and F3. For 230V to 240V countries, the fuses are removed from F2 and F3
and one fuse in inserted in F4. All units can be assumed to be set up for 120V operation unless a 240V gold sticker is
attached to the back of the unit. Replace fuses with 3A 5mm x 20mm miniature fuses. Fuses may blow during unusual
power surges or disturbances. Protect this product with a good surge protection power supply as changing fuses is quite
a big operation.
MSB Network Input and Channel Selection
The MSB Network supports 4 stereo channels
of 192k data at once. Any DAC can be config-
ured to decode any of these 4 channels. For ex-
ample, 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 re-
ceive and decode the rear channels. The 3rd chan-
nel 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.
More than one DAC can be attached to the same cable by taking ad-
vantage of a DAC with both an input and output like the Platinum to
