Digital Inputs
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.
ATT Glass – This ST type optical input is robust and high speed, but less commonly used. This input is offered as a
customer installable option.
Balanced – 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. It is used for both digital audio and the MSB Network. The Platinum is configured
connector next to the AC power connector is an auxiliary output, not an input. MSB will supply a DIN to DIN cable
upon request.
Dual MSB Network – These dual CAT-5 connectors are actually a bridged input and
provide a second MSB Network input or output. Multiple DACs can be daisy chained
together using one connector as an input and the other as an output.
The MSB Network
One of the most powerful new features of the Platinum is that it is the first product to
incorporate 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 fol-
lowing capability:
* Unidirectional communications over any twisted pair
* Simultaneous transmission of 8 audio channels with 34 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 transmis-
sion in the same package. We provide network outputs to our own transport and offer
a source upgrade to your transport as well. In our next generation surround processor
upgrade, up to 8 channels of decoded data can be sent through one wire. The twisted
pair format is very convenient as it has be-
come the standard for all computer net-
works. Ethernet networks use CAT5 wire which contains 4 twisted pairs.
This one cable could be used to send 32 channels of 34 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 and CAT5 to XLR
cables.
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).
Coaxial – We combine the inverted and non-inverted DAC outputs in a high-speed summing amplifier. The output
impedance is 75 ohms and output level is 12 Volts PP (4 V RMS). This rather hot output can be attenuated using a
special cable included that reduces the output to standard line level. Use this cable when a high gain preamp is part of the
system. Use standard cables when a low gain or passive volume control is used.
