Overview
Each MB-651 is a compact 3G/HD/SD SDI embedded audio monitoring system designed to
extract up to 16 channels of embedded audio from an SDI signal for visual and aural monitoring.
The MB-651 features an intuitive user interface to allow for easy access to the signals and
information you need to monitor.
A large vacuum fluorescent display on the front panel reports VU/PPM information, LKFS
ITU1770-3/1771 loudness measurements, and true peak measurement. Input signal format data
and mode selection information is also displayed.
Located directly beneath the display are 12 illuminated push-buttons to provide intuitive channel
source and mode selection.
Also located on the front panel is a push to mute rotary shaft encoder for volume control and a
1/4” long-frame jack for headset monitoring.
One 3G/HD/SD SDI signal can be connected to the BNC on the rear panel while a reclocked
output is available. Two 3-pin terminal block connectors also provide a stereo monitor output.
Features
The following features come standard on the MB-651:
• One 3G/HD/SD SDI input
• One reclocked SDI output
• One stereo monitor output
• Left, Right, SUM, Left Total/Right Total (Lt/Rt) downmix modes
• Push to Mute rotary shaft encoder
• High quality 1/4” long-frame headset jack
• 16 VU/PPM bar graph meters
• Provides ITU 1770-3/1771 LKFS measurements
• Provides parametric equalizer adjustment

1–4 • Introduction MB-651 User Manual (Iss. 04)
User Interfaces
The MB-651 is intended to be controlled via the DashBoard client software, as well as through
the physical controls on the panel.
DashBoard Control System
The DashBoard client software enables you to monitor and configure the Monitoring Bridge from
a computer. The DashBoard software is available for download from our website.
The MB-651 includes two DashBoard interfaces: Network Connect and MB-651. Both interfaces
are accessed by expanding the Monitoring Bridge node in the DashBoard Tree View and selecting
the appropriate sub-node. The Network Connect interface enables you to set up ethernet
communications, and monitor those communications. The Monitoring Bridge interface includes
operational controls for the physical panel such as selecting the input source for the speakers and
adjusting the volume level for the speakers.
For More Information on...
• configuring the Monitoring Bridge for network communication, refer to the section
“Network Configuration” on page 3-6.
• menus in DashBoard for the Monitoring Bridge, refer to the chapter “DashBoard
Menus” on page 4-1.
• installing and using DashBoard, refer to the DashBoard User Manual.
Controls on the Physical Panel
The front panel of the MB-651 provides the ability to monitor the LKFS and true peak values, the
input signal format, and meters that represent VU/PPM data and loudness measurements. Buttons
are provided to routing audio sources to the speakers, selecting the operating mode, and volume
control.
The rear panel provides connections for the power supply, BNCs for the SDI input and output,
and two 3-pin blocks for monitoring the analog audio.
For More Information on...
• the control and monitoring features of the front panel, refer to the section “Front Panel
Overview” on page 2-3.
• the connections provided on the rear panel, refer to the section “Rear Panel Overview”
on page 2-4.

Physical Installation
The MB-651 mounts in the rack frame by means of four rack screws fastened through the front
mounting ears. This should normally be sufficient to carry the load, including the weight of
accompanying cables. Note that the MB-651 installs in a standard 19” rack.
Installation Requirements
Keep the following in mind when installing your MB-651:
• Install the MB-651 for maximum stability during operation and in such a way as to allow
adequate ventilation.
• The MB-651 cannot be sealed in a closed container and must be installed in free air space
where the ambient temperature is monitored and controlled to not exceed 40°C (104°F).
• Ensure that adequate space exists in front and behind the MB-651 and on both sides of
the frame for airflow.
• The location of the MB-651 should be accessible, dry, and dust-free.
Power Supplies
The MB-651 comes standard with one power supply and one A/C power cable. A redundant
power supply is available as an option. The MB-651 power supply is a power factor corrected
supply, capable of working with all world AC standards (100-240V).
This section includes information for connecting the power cables for the MB-651.
To connect the power cables for the MB-651
1. For each power cable, install the provided cable clamp (929-006R) and machine screw
(850-005R) to help retain the power cable connectors to the rear of the MB-651 chassis.
These clamps and screws are included in the shipping container with the MB-651.
2. Connect the DC plug to the power jack located on the rear panel of the MB-651. Refer to
Figure 2.2 for power connection location.
3. Connect the line cord to the power supply.
4. Connect the AC cord to an AC outlet.

Warning Hazardous Voltages — The safe operation of this product’s external
power supply requires that a protective earth connection be provided. This protective
earth is provided by the grounding conductor in the equipment's supply cord. To reduce
the risk of electrical shock to operator and service personnel, this ground conductor must
be connected to an earthed ground.
Warning — In some countries, it may be necessary to supply the correct mains supply
cord. Use only an approved IEC 320 C-13 type A/C line cord rated for a minimum 10A at
250V and certified for the country of use.

2–6 • Installation MB-651 User Manual (Iss. 04)
Ethernet Cabling for the MB-651
The exact steps for connecting to your facility via an ethernet network depends on the network
requirements of your facility.
Contact your IT Department before connecting to your facility network to ensure that there are no
conflicts. They will provide you with an appropriate value for the IP Address, Subnet Mask, and
Gateway for the MB-651.
You will require a standard network CAT-5 cable to connect the MB-651 to your facility network.
Ross Video does not supply this cable.
SDI Cabling
The rear panel includes one SDI IN BNC and one SDI OUT BNC.

Configuring the DIP Switches
This section briefly summarizes the DIP Switch settings on the MB-651. Figure 2.3 shows the
DIP Switches in the UP position.
Figure 2.3 DIP Switches — Set to the UP Positions
Setting the IP Address
SW1 and SW2 are used in conjunction with the DashBoard menus to set the IP Address of the
MB-651. Refer to Table 2. 2 for DIP Switch positions. For information on configuring the
network settings for your MB-651, refer to the section “Network Configuration” on page 3-6.
Master Password Override
SW3 is used to override the Master Password and allows a user to reset the Master Password.
Refer to the section “Using a Master Password in DashBoard” on page 3-4 for details.
•UP — This is the recommended position. A user-specified Master Password is used. The
default password is password. It can be changed using DashBoard as outlined in the the
section “Setting the Master Password” on page 3-4.
•DOWN — This position is used to recover a lost Master Password. The user-specified
password is temporarily ignored, and the default value of password is used.
