Introduction
The DaySequerra M4DDC Diversity Delay Control is a purpose-built, 1 RU, stand-alone AM or FM
solution and runs DaySequerra’s new proprietary TimeLock
TM
algorithm to automatically maintain
perfect time and audio level alignment of the HD Radio
TM
MPS and HD-1 audio streams.
The M4DDC receives the off-air broadcast measures the time difference between the MPS and HD-1
streams, automatically generates correction vectors necessary to compensate for the offset, and
maintains perfect alignment between the two streams.
Please read this manual thoroughly before operating your M4DDC.

Experiencing TimeLock™ for the First Time
To fully understand the power of TimeLockTM in action it is highly recommended to experience it with
and without the TimeLockTM Correction algorithm running. First start by disabling TimeLockTM
Correction from the webserver and tune to an un-aligned FM broadcast to hear the misaligned MPS
and HD-1 audio streams.
Uncheck the TimeLockTM Correction box (Figure 2) followed by clicking on Save Settings.
Figure 2
The webserver will then start to ‘Acquire Data’ from the two audio streams and begin correlating them.
In our example below (Figure 3) the Correlation Threshold is set to 70% (Default). Acquired data that
is below this threshold is not correlated and displayed in RED. Acquired data > 70% is considered
correlated and is displayed in GREEN.
Listening to the M4DDC-FM Demo is recommended with headphones. Plug the headphones into the
3.5mm stereo mini-jack connection located on the right side of the M4DDC-FM Demo front panel.
Hearing the misaligned audio streams is very easy using HD Radio Split-Mode audio - HD-1 audio is on
the Left Channel and MPS is on the Right Channel. The TimeLock
TM
webserver display makes
diversity delay measurements simply intuitive. In our example on the next page the MPS is behind by
43.5 MS or +1919 Audio Samples

Two audio streams that are only a few MSec out of alignment will sound like an echo with headphones.
Now turn the proprietary TimeLockTM Correction algorithm back on by checking the TimeLockTM
Correction box followed by clicking on Save Settings. TimeLockTM will delay the HD-1 stream until it is
coincident with the Main Program Stream. The audio you now hear becomes sublime. (Figure 5)

Private FTP
Private FTP points the M4DDC toward a private FTP site, bypassing DaySequerra’s public FTP used
for updates. Switch the ‘Enable Private FTP’ slider ‘ON’ and enter the private FTP credentials in each
field followed by clicking ‘Save’. Enabling this feature will keep the M4DDC from downloading or
checking for updates directly from DaySequerra. By doing this the M4DDC will not know when new
updates are pushed to the public FTP site by DaySequerra. Please notify DaySequerra so future
firmware updates are sent directly to the user in binary form.
Network Settings
Configures all network connections. DHCP is enabled by default. By disabling DHCP a manual IP
Address, IP Subnet, Gateway are able to be set by entering the data in each field followed by ‘Save’.
MAC is read only. After the Network settings are saved the M4DDC will reset itself so the new network
settings are enabled.
Other Settings
• Firmware Updates
o ‘Check for update’ checks DaySequerra’s public update site against the firmware
version that is listed in the ‘ABOUT’ section. If an update is available the option to
download and install will pop-up. Updates are not automatic. If the Firmware is up to
date a message will pop-up displaying the firmware is up to date. Because the updates
are not automatically checked it’s good practice to periodically check for updates by
selecting ‘Check for Update’.
o
Local update allows the user to perform a firmware and webserver update from a local
network drive. Like using a private FTP, it is necessary to notify DaySequerra for the
latest binary firmware. See figure xx.
o
‘Downgrade Firmware’ enables the user to downgrade back to the last stable release
stored on DaySequerra’s FTP site. A pop-up message asks to continue or cancel.
• ‘Reset Unit’ performs a soft reboot of the M4DDC unit.
• An up to date user manual is always available for download by selecting ‘Download Manual’.
The webserver will be redirected to DaySequerra’s website www.daysequerra.com. Navigate to
/Broadcast Radio/HD RadioTM TimeLockTM /M4DDC TimeLockTM. Click on ‘Manual’ and
‘Download PDF’

Webserver – Logging Tab
A log of TimeLockTM, Level Lock, Audio Phase, and Alarms may be exported in .csv format to an FTP
site for download. Data is only logged if it crosses beyond the threshold limits that are set in the ‘Log
Threshold’. Audio Phase and Alarms are always logged and do not have a threshold. Log categories
can be selectively enabled and disabled. Data is stored in a buffer until the set limit (KB) is reached.
The buffer will then upload the log to the defined FTP ‘Log Directory’. The unit will not log data unless
the Log Directory is enabled. An ‘Upload Log Now’ button is available to quickly upload any data that is
stored in the buffer to the directory. Each time this action is performed the log starts over. Logs are
saved with a timestamp, Device name and serial number.

Restore Factory Settings
To restore your M4DDC unit back to the original factory settings hold the UP arrow button in while
power cycling the unit. Continue to hold the button in until the message ‘Restoring to factory settings’ is
displayed on the LCD. Be sure the M4DDC is connected to a network with access to the Internet so up
to date support and webserver files are downloaded properly. The original factory default settings will
then be restored.
Displays ‘Locked’ when the M4DDC has acquired an AES lock on a
respective input.
‘Unlocked’ is displayed when there is no AES lock present.
