Broadcast Digital Audio Loudness Monitor

Follows ITU and EBU loudness standards

Traditional PPM and VU meters measure the physical property of audio itself, while loudness is the subjective feelings of human beings. People may feel uncomfortable if different TV programs have different loudness level. In order to regulate the audio loudness in broadcast industry, International Telecommunication Union (ITU) and European Broadcasting Union (EBU) established standard of how to calculate loudness and what is the target loudness value that people feel comfortable.
SWIT M-1072A is the right monitor for SDI/HDMI embedded audio loudness monitoring, follows ITU-R BS.1770-3 and EBU-R-128 standards.

 

 

7-inch 1024×600 LCD


FFS panel with LED backlight


The M-1072A provides a 7-inch FFS (Fringe field switching) LCD panel, with 1024×600 resolution and LED backlight, 400cd/m2 brightness and 900:1 contrast. The viewing angle is Horizontal: 160° / Vertical: 160°.




3.0-inch antimagnetic coaxial speaker


Equipped with 2 of 3.0-inch antimagnetic coaxial speakers, the M-1072A can output high quality embedded audios. The frequency response range is 130Hz(±5Hz)~22KHz.
M-1072A also supports SDI/HDMI embedded audio output via 6.35mm headphone socket.






 

 

Multi-format Input/Output

SDI / HDMI

M-1072A rack monitor supports:
HD/SD-SDI input × 2
HD/SD-SDI loop output × 2
HDMI input × 1
HDMI loop output × 1


 

 

VU/PPM meters and Loudness Meter


For SDI/HDMI embedded audio


M-1072A can display 2 channels (ch-1&2) of SDI/HDMI embedded audio VU/PPM meters, and the SDI/HDMI realtime loudness meters.
The VU/PPM meters are green, and will turn yellow when audio level exceeds -20dB, and will turn red when exceeds -9dB.
The Loudness meter marked -26LKFS to -22LKFS as the target comfortable section, regulated by ITU and EBU standards.


 

 

History Loudness Trace

By waveforms

The realtime loudness meters and value can hardly tell people how loud the audio is. We need to record and mark the loudness values in a period of time, and display the run chart, so that people can check the loudness level visually.
M-1072A monitor offers the history loudness run chart of past 1 minute period, and user can set a particular time period to define the second run chart.



 

History Loudness Count

By histogram

Besides the waveform trace of past period loudness values, M-1072A monitor also designed the histogram to statistics a complete program time of loudness values. People can check if the most of loudness values are distributed into -26LKFS to -22LKFS, the “Target comfortable section”.
The green histogram is to count the complete time, and purple histogram is to count the user defined period of time.


 

 

Audio Lissajous phase pattern

The Lissajous pattern provides instantaneous feedback of the left/right audio channel distribution during a remix. The pattern orientation indicates at a glance whether the present mix is balanced or concentrated to either side, and the distance of the spot to the center indicates the audio level.



 

Quad-split or Full-screen Display

Display video and audio graphics simultaneously

The 7” LCD can be quad-split to 4 sections, and each section is user definable, to display video or either of the audio graphics, including realtime meters, waveforms, histograms and Lissajous. Moreover, users can also set each of the section to full screen display.


 

 

Power Supply

M-1072A provides a 4-pin XLR socket of DC 6.5-17V power input, and an AC-DC adaptor is attached on the rear panel of the monitor.



 

 

3-color TALLY Light

DB-9 input signal

There are front TALLY lights for each screen, with 3 colors display, and controlled via DB-9 ports on the rear panel.

Various types of DV battery plates are provided for optional, with snap-on designed, quick released and interchangeable with each other. There’re following DV plates for selection:



Installation

M-1072A is standard 19” rack mount fixing, occupies 3U height. The monitor is ±30° up and down rotatable when installed on racks.

VU/PPM meters and Loudness Meter

The VU/PPM meters only supports the first 2 channels of the SDI or HDMI embedded audios, and will warning when VU/PPM value is over -9dB.
The Loudness meter marked -26LKFS to -22LKFS as the target comfortable section, which is regulated by ITU and EBU standards. The broadcast target is to guarantee that the audio loudness value is between -26LKFS to -22LKFS for the most of times.


 

Histroy Loudness Trace

People can hardly get the loudness impression if only read the realtime meters and values. So the M-1072A function: History Loudness Trace, is to record and mark the loudness values in the past period of time.
The upper waveform is to record the past 1 minute time, and the lower waveform is to record user defined time period, from 2 min, 5 min, 10 min, 30 min, 1 hour and 2 hours.
The broadcast target, is to guarantee that most of the waves are marked between -26LKFS to -22LKFS section, the ITU and EBU regulated comfortable section.


History Loudness Count



M-1072A monitor also designed the histogram to statistics the distribution of loudness values.
The green histogram is to count the complete time, and purple histogram is to count the user defined period of time, from 2 min, 5 min, 10 min, 30 min, 1 hour and 2 hours.
The broadcast target, is to guarantee that most of the loudness values are distributed between -26LKFS to -22LKFS section, the ITU and EBU regulated comfortable section.
