precaution is faithfully observed. The firmware update process takes about 20-30 seconds and you MUST NOT INTERRUPT THE
POWER TO THE PLATINUM while the new firmware is loading. You must wait for the message after the Firmware Update before
interrupting your Platinums power. If the power to the Platinum is interrupted during a firmware update you will have to return your 16x
Digital Filter Board to MSB for reprogramming. MSB will charge you a small fee for this service. If you have accidentally loaded
firmware that you do not wish to have on your Platinum do not try to cancel it while it is loading, simply wait for the update to complete
and then load the firmware you do wish to have on your 16x Digital Filter Board.
Step One, Verify Your Equipment Compatibility - To successfully load your new Firmware you must have your Platinum connected to a
transport that will not change the DATA. Almost all CD Players are acceptable however there are some exceptions. Upsampling CD
transports will not work; this includes the drive internal to the older Platinum Reference CD Player and Platinum Reference CD Station 2.
To load a firmware file to these machines you will have to connect your Platinum to another source to load the firmware. The Upsampling
drives are fine for playing audio after the upload however. DVD players should work fine when they are configured in a mode that does
not affect the Data such as CD pass-through mode when connected to their s/pdif digital output.
Step Two, Burn the CD - When burning a CD containing the new firmware you must burn the WAVE audio file directly to a CD without first
converting it to another audio format such as MP3. Converting the WAVE file to another format will destroy the careful formatting which
allows DSP to load its new Firmware directly from a CD. You cannot however corrupt the Firmware in a way that will allow it to load
incorrect software. The firmware update file is protected by powerful error detection and encryption that will not allow a damaged file to
be loaded into the DSP. A corrupted or damaged firmware CD will simply be rejected by the DSP and fail to load the new software.
Step Three, Play the CD - To ensure a proper load of the firmware you must remember to disable any digital processing before the 16x
Digital Filter. This includes turning off any processing in DVD players, Upsampling in CD players and Upsampling in the Platinum itself.
If the Filter Load Fails (the equipment is not compatible or the track is not played trough the MSB 16x Digital Filter) the track containing
the new firmware will play a short very quiet noise burst followed by a Firmware Update Failed message. A successful load will just be a
20-30 second silence followed by a New Firmware Conformation message. The new firmware is running at this point, you do not have to
restart your Platinum to enable the new features.
Step Four, Enjoy Your New Features - Custom Firmware permanently changes the software running on your DSP. This change occurs
immediately following a firmware update. You do not need to reset or power off your Platinum. Powering the unit off after a firmware
update will load the new software on power-up, the old software was completely erased. If you are not happy with your new firmware
simply load your old firmware using the instructions above.

On the back of the unit is a special 5 pin XLR type connector. It is a clock interface that allows multiple
Platinum products to be synchronized, allows the Platinum Clock to be output and allows an external
clock to be input to the Platinum. The interface is a LVDS format clock interface with a signal level of 250
mV pp input or output requirement.
Pin Identification - The pins shown in the figure above are identified as follows:
1. Ground
2. Clock Select (OPEN = Master Clock Output, LOW = Master Clock Input)
3. M Clock + (Positive side of balanced Master Clock)
4. M Clock - (Negative side of balanced Master Clock)
5. DSP Ready for Networking (OPEN = OK to Run, LOW = Stop, not ready)
Clock Frequencies - By toggling the Clock Select line clocks can either be input or output. The output frequencies are as follows:
· 44.1, 88.2 or 176.4 kHz sampling frequency source outputs a clock frequency of 22.5792 MHz
· 48, 96 or 192 kHz sampling frequency source outputs a clock frequency of 24.576 MHz
The input frequency requirements are as follows:
· 44.1 kHz source will accept a 11.2896 or 22.5792 MHz input
· 48 kHz source will accept a 12.2880 or 24.576 MHz input
· 88.2 or 176.4 kHz source will accept a 22.5792 MHz input
· 96 or 192 kHz source will accept a 24.576 MHz input
