Overview
The MB-652 Monitoring Bridge 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 Monitoring Bridge 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
ITU1770/1771 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.
High quality full range speakers and a Class D amplifier provide unparalleled performance.
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-652:
• 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

User Interfaces
The Monitoring Bridge is intended to be controlled via the DashBoard Control System 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 Monitoring Bridge includes two DashBoard interfaces: Network Connect and MB-652. Both
interfaces are accessed by expanding the Monitoring Bridge node in the DashBoard Tree View
and selecting the appropriate sub-node. The Network Connect 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 Monitoring Bridge 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 Monitoring Bridge 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 Monitoring Bridge installs in a standard 19” rack.
Installation Requirements
Keep the following in mind when installing your Monitoring Bridge:
• Install the Monitoring Bridge for maximum stability during operation and in such a way
as to allow adequate ventilation.
• The Monitoring Bridge 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 Monitoring Bridge and on both
sides of the frame for airflow.
• The location of the Monitoring Bridge should be accessible, dry, and dust-free.
Power Supplies
The Monitoring Bridge comes standard with one power supply and one A/C power cable. A
redundant power supply is available as an option. The Monitoring Bridge 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 Monitoring Bridge.
To connect the power cables for the Monitoring Bridge
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 Monitoring
Bridge chassis. These clamps and screws are included in the shipping container with the
Monitoring Bridge.
2. Connect the DC plug to the power jack located on the rear panel of the Monitoring
Bridge. 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.
