and true peak measurements are made to the ITU-R BS.1770 standard with five times
oversampling.
Included settings match EBU R 128, ARIB TR-B32, and ATSC A/85 recommendations.
Internal memory stores five days of loudness and alarm data. Logs can be exported via
Ethernet or USB. Remote control and monitoring can be performed from any web browser.
The LLM-1770 comes with four AES inputs and has options for Dolby decode and SDI
embedded from SD, HD or 3 Gb/s sources. There is a headphone jack for local confidence
monitoring. A standard LLM-1770 with the Dolby decode option installed is considered an
LLM-1770-D.
The LLM-1770 features audio alarm capabilities, including peak audio reporting. Real-time
signal alarms have user adjustable limits. Remote interfaces include 10/100Base-T Ethernet
and plug and play USB port (supporting export of log and alarm files as well as flash
updates). The

Installation
Rack Mounting the LLM-1770
When selecting the permanent mounting location for the LLM-1770, make sure that the
flow of air to the ventilation holes on the top and sides of the chassis is not obstructed .
Rack mounting the LLM-1770 is illustrated in Figure 2-1 for the DRT-4A rack mount case.
Table 2-1 lists the parts required to rack mount the LLM-1770 into the DRT-4A rack mount
case.
Figure 2-1 Mounting the LLM-1770 in a Rack Using the DRT-4A
Although only one LLM-1770 unit is shown in Figure 2-1, two LLM-1770 units may be
mounted into a DRT 4 rack case.

If Latched is selected the output will close on the leading edge of any enabled

IP: This selection is used to configure the LLM-1770 for Ethernet communication. The
Ethernet interface provides a high-speed communication link to the third party
applications (such as web browser) over standard LAN and Internet networks. The
interface conforms to industry Ethernet standards:
Connection via a standard RJ45 socket
Automatic detection and switching between 10Base-T and 100Base-T
TCP/IP stack is fully compliant with RFC2500, “Internet Official Prot ocol Standards”
Fully compliant with IEEE 802.3 Ethernet standard
The interface can accept a static IP address, or it can obtain an IP address dynamically
from a DHCP server. The IP Address, Subnet Mask, Gateway Address, DHCP enable,
and Port are programmable from the unit's Ethernet Setup menu. The settings are
performed in the IP Configuration screen.
DHCP Control: The Dynamic Host Configuration Protocol (DHCP) function is used
to have the
LLM-1770 automatically configure an IP Address, Subnet Mask, and
Gateway every time the unit is powered on. The IP Address is dynamic and could
change each time the
LLM-1770 is powered on. DHCP Enable is set to OFF by
default.
IP Address: The IP Address is used to select a static IP addr ess (unless DHCP will be
used). The IP address must not be the same address as another instrument or PC on
the network. Network conflicts will occur if two devices have the same IP address.
See the System Administrator to determine a static IP address that will avoid
conflicts.
Subnet Mask: The Subnet Mask is used to configure the Subnet Mask on a
network if DHCP is not enabled. If DHCP is not used to automatically detect the
Subnet Mask on a network, the Subnet Mask must be manually configured. Unlike
the IP address, the Subnet Mask must be the same Subnet Mask as the network
Subnet Mask. See the System Administrator to determine the Subnet Mask.
Gateway: The Gateway is the network address that provides access to an outside
network. Use the Gateway submenu to configure the Gateway on a network if
DHCP is not enabled. If DHCP is not used to automatically detect the Gateway on a
network, the Gateway must be manually configured. Unlike the IP address, the
Gateway must be the same Gateway address as the network Gateway address. See
the System Administrator to determine the Gateway address.
Front Panel Lock: This selection is used to enable the fr ont panel auto lock funct ion. If
enabled, the front panel will automatically lock after 30 seconds of no front panel
activity.
System Time: This selection allows the setup of the clock display's date and time.
Logs: This selection is used to set up the device’s alarm logs.
Naming Convention: This selection allows the user to select a device serial
number or use a custom string to identify a particular device.
Custom String: If a user identified “Custom String” as the Naming Convention
parameter selection, this selection enables the entry of a nine-character entry.
Alarm Log: This selection allows the user to set the Alarm Log function to either
overwrite the oldest alarm entries when necessary (thereby allowing a continuous
list of alarm entries), or to stop writing entries to the alarm log when the disk is full.

Peak Audio: The Peak Audio alarm occurs when the peak audio level exceeds the
adjustable limit for a period in excess of the duration setting. The level limit can be set
from -30 dBFS to 0 dBFS, in 1 dB increments. The peak audio duration can be set from
0 to 60 seconds.
Loss of Sound: The Loss of Sound alarm occurs when the peak amplitude falls below
an adjustable limit for a period in excess of the duration setting. The audio range is -60
dBFS to 0 dBFS, in 1 dB increments. The Loss of Sound duration can be set fr om 0 to 60
seconds.
Digital Clip: The Clip alarm occurs when the audio is at a maximum level for a period
in excess of the duration setting. For the LLM-1770, the accuracy of the audio clip
alarm is 0.

data packets are not present. Dolby E VANC packets are identified by DID: 0x45 and
SDID: 0x01 - 0x09. This alarm is enabled by SDID value.
Dialnorm: The Dialnorm alarm occurs when the Dolby E VANC metadata dialnorm
value for the enabled program falls outside selected minimum and maximum values for
the duration. If the Dialnorm Source in the Dolby Setup menu is set to VANC, the
dialnorm value from the Dolby D Essential payload is the specific dialnorm value used
for this alarm. If the Dialnorm Source is set to Dolby Decoder, the dialnorm value is
extracted from the metadata in the audio stream specified by the Input selection in the

Log File Contents
The LLM-1770 has three types of capture files: data, and alarms, and summary files.
A data file represents an entir e day’s worth of raw loudness values. Entries are recorded
at a 100 ms rate for both program 1 and program 2.
An alarm file represents an entire day’s worth of alarm events. Alarm events are written
to the log as they occur. Menu options control how the box operates if the number of
alarms exceeds the storage capabilities of the device.
A summary file represents a snapshot event of loudness measurements and settings.
You can manually trigger an event by pressing the CLR button. An event is
automatically triggered 24 hours after the last clear event.
A new log file is created when the system
time rolls over to the next day.
