Inputs

Analog (SACD) – A balanced analog input is provided.

It is passed through to both the single ended and

balanced outputs when selected. (As well as the volume

control if installed). This input is ideal for adding an

SACD player to your system. Minimum input impedance is 600 ohms. For an RCA input, use an RCA to XLR conversion connector. At

0 dB volume setting, the analog inputs are a direct pass-through.

Toslink – Although this format has the lowest bandwidth, it is one of the more common outputs on low-end products. It also offers ground

isolation between products and noise immunity over long runs.

Coaxial – A good input for short runs and lower frequencies.

Balanced digital – The AES/EBU Professional input is the preferred input. The balanced nature of this input allows great cable lengths

as well as total noise immunity.

Dual MSB Network – These dual CAT-5 connectors are actually two inputs. One is MSB 5 and the other is MSB 6.

The MSB Network

One of the most powerful features of the Platinum is the new MSB network. This

network plugs into the balanced input of the Platinum and is automatically detected and

activated. The MSB network has the following capability:

* Unidirectional communications over any twisted pair

* Simultaneous transmission of 8 audio channels with 32 bit resolution at 192

kHz sampling rate

* Simultaneous transmission of 8 data channels with 3 Mbs data rate (for volume

and trim data)

* A single serial channel of 384 kbits/sec for control and system data.

This network is our answer to 192 kHz audio transmission and multichannel transmission in the same

package. We provide network outputs to our own transport and offer a source upgrade to your

transport as well. In our surround processor upgrade, up to 8 channels of decoded data can be sent

through one wire to separate DACs. The twisted pair format is very convenient as it has become the

standard for all computer networks. Ethernet networks use CAT5 wire which contains 4 twisted pairs.

This one cable could be used to send 32 channels of 32 bit, 192 kHz audio data! Several cables are

available for connecting MSB transports to the Platinum including CAT5 cable at any length up to 80

feet.

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 (3.6V RMS). Set the

volume control at -6dB 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 voltage switchable

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

The Platinum can be configured for 120V or 240V 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 120V setting and

180V will work at the 240V 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 3A 5mm x 20mm

miniature fuses. To access the fuses, follow these instructions:
