Analog Outputs
Balanced – The balanced audio outputs are the preferred output format for those customers with a balanced system. As the PLATINUM
is fully balanced, both the inverted and non-inverted outputs are generated directly by separate DACs and sent to the balanced outputs
without filtering, buffering or any analog circuits that could color the music. The balanced outputs provide a 20 Vpp at 0 dB (7.5 V RMS).
Set the volume at -12 dB to achieve a 2 Vrms output level
Coaxial – The output impedance is 50 ohms and output level is 10 Volts PP (3.6 V RMS). Set the volume control at -6 dB to achieve the
industry standard 2 Vrms level.
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 120 V or 240 V 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
The Platinum can be configured for 120 V or 240 V operation by switching the voltage switch on the back
panel. The Platinum will work over a wide voltage range so 80 volts is no problem at the 120 V setting and
180 V will work at the 240 V setting.
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. Replace fuses with 3 A 5 mm x 20 mm
miniature fuses. To access the fuses, follow the instructions below.
Upgrades and Modifications
Removal of the cover
- Unplug the AC power. Work on a soft scratch resistant surface like a carpeted floor. Start
with the unit upside down and remove three screws located along the front edge of the cover. Then turn the unit over
and remove the three screws along the back edge of the cover. Loosen the four screws holding the endcaps on as they may prevent the cover from moving
easily. Slide the cover toward the front of the unit and lift up. Carefully reach in and unplug the cable from the front. Set aside the cover.
1) Remove or loosen one Side Panel
(End Cap) by removing 4 Allen
Screws as shown.
2) Remove 6 Philips screws from top
and bottom of cover. Remove
cover, and disconnect ribbon cable
that attaches the Front Display to
the Platinum Main Board.
Reference CD Players will have
more than one ribbon cable; both
will have to be removed. Set cover,
Screws and End cap aside.
