Digital Input Module - Dual PRO I2S
This digital module is like two modules in one.
Both are MSB proprietary inputs capable of
accepting data streams up to 32 bits and 384 kHz
as well as DSD up to quad rate. Note that some
MSB sources may have a limited output rate.
Part of the PRO I2S interface includes a master
clock link so no additional clock sync connection
is needed. This issue of clock sync is not easy to
understand. The quality of the data being received
is not changed by syncing the source, but the
noise associated with recovering the data from a
"different" clock is substantially less.
Digital Input Module - Balanced XLR with Word Sync Clock Output
This digital module is a single input. It is the industry standard S/PDIF input capable
of accepting data streams up to 24 bits and 384 kHz as well as DSD via DoP up to
double rate. Note that some sources may not be able to output this high a rate on
this format connector but at least the input can handle it. It is very valuable to keep
the source in sync with the DAC so we provide a Word clock output using a BNC
connector that would allow you to sync with the source. This sync is primarily a
feature for studio use, where the ultra low jitter DAC clock can be used as the master
studio clock. This issue of clock sync is not easy to understand. The quality of the
data being received is not changed by syncing the source, but the noise associated
with recovering the data from a "different" clock is substantially less.
The MSB PRO I2S Network
One of the most powerful features of MSB products is the PRO I2S network. Most MSB
products have a PRO I2S connection available. The MSB PRO I2S has the following
capability:
•
Works with standard CAT6 cable
•
Simultaneous transmission of 8 audio channels with 32 bit resolution at 384 kHz
sampling rate.
•
MSB CAN Interbox communication Bus (for communications between
boxes)
•
Low Jitter master clock distribution from the DAC back to the Transport.
This network is our answer to 384 kHz audio transmission and multichannel transmission
in the same package. We provide PRO
I2S outputs on our own transports. With
multichannel sources, up to 8 channels of
decoded data can be sent through one
wire to separate DACs. CAT6 wire is
very convenient as it has become the
standard for all computer networks.
Several cables are available for
connecting MSB transports to the
SELECT Line including CAT6 cable
at any length up to 80 feet.
NOTE: Do not use CAT7 or any
shielded network cable. This is
NOT a computer network and it
will not work.
