DB6 Broadcast Audio Processor
Let DB6 manage your audio loudness to stay compliant with broadcast standards and legislation at all times, without sacrificing audio quality.
DB6 handles up to three SD/HD/3G streams in a single rack space unit. It measures and adjusts audio formats, loudness and true-peak level automatically, at the same time logging stats for documentation and evaluation.
DB processors have been used 24/7 at numerous world-leading
broadcast stations for more than a decade and you can operate them
from one constantly developing user interface.

One-Step Loudness Management
Quite simply, DB6 is a TV and Mobile TV transmission processor that is able to handle everything regarding loudness in one simple process: loudness metering at the input stage, up- and/or down conversion at any stage, loudness processing, on-line lip-sync delay, loudness metering at the output stage and logging of all relevant loudness statistics.
In short, it is an intelligent one-step loudness management solution that even keeps your audio at its finest, regardless of which platform you need to deliver to.
Density is key at many broadcast stations and of course in OB Vans. Therefore, DB6 is housed in a single rack space unit that allows you to process up to three SD/HD/3G streams simultaneously, making it one of the most compact and powerful solutions on the market.
Surely, density does not necessarily equal cost-effectiveness, but in this particular case, the cost per stream is highly competitive. With DB6, you get two 5.1 capable processing engines per SDI stream, each able of delivering to any platform and any codec; be it HDTV, Mobile TV, Digital Radio or Podcast using AAC, Dolby, Ogg Vorbis, Lossless or Linear.
DB6 is compliant with all major broadcast standards, and it comes fully loaded with presets tailored specifically with each of these standards in mind.
However, it is not just a matter of being compliant, it is also imperative to stay compliant.
We have taken part in many aspects of defining and developing these standards and remain dedicated to keeping our broadcast equipment up to date whenever a new revision is released.
DB6 is like having a Plug & Play solution to Loudness. It combines all your loudness related tasks into one simple, easy-to-operate process. Once it is set up, you can leave it alone to work its wonders, and while setting it up the, you'll notice how flexible the unit is.
As the diagram shows, you can apply two LoudnessWizard algorithms to each SDI stream, but on top of that you can also add one or two LM6 Loudness Radar Meters on either side of the LoudnessWizard in order to measure loudness before as well as after any processing has happened.
The LoudnessWizard™ algorithm takes care of loudness correction, up-conversion from stereo to surround formats and down-conversion from surround to stereo.
It doesn't matter if you know every detail of the inner workings
of loudness standards - just apply LoudnessWizard™ and let it
combine and chain together multiple processes on the fly.

LM6 Loudness Radar Meter™
Our LM6 Loudness Radar Meter measures loudness at the input stage as well as the output stage of DB6.
In short, it shows you the essence of your loudness landscape at a glance for a complete and instant overview, including Loudness History, Momentary Loudness, True-peak Level, Program Loudness and Loudness Range (LRA) in a single view.
Redundancy & Reliability
It does not matter how well a transmission unit does its job, if it is not completely reliable. Being the last line of defense in a live scenario calls for ultimate redundancy and realiability.
We're serious about being fail-safe. Not only have we given you what you would expect - dual fans and dual fuses - we've also packed the DB6 with dual power inlets. You are now virtually risk-free of losing power while on air.
We are aware that DB6 is inserted at a very critical point in your audio signal path and that it is an 'always on' type of unit that needs to deliver a non-stop performance years over years. Should the unlikely event happen that DB6 loses power, rest assured that your transmission will go on thanks to the Relay Bypass feature that passes your stream directly from input to output no matter what happens.
Further, if one of the power sources fail, you can be notified using GPIO or SNMP traps.

Two Versions - DB6 Multi & DB6 Single
DB6 is available in two different versions: DB6 Multi and DB6 Single. At first glance they look quite similar, but on the rear panel, you will notice a significant difference. As the name implies, DB6 Single handles one SD/HD/3G stream, which makes it the perfect choice if you are a local broadcaster or need intelligent loudness management in an OB van.
DB6 Multi also comes with the ability to process one stream
right out of the box, but you can also install one or two
additional 'Transmission 3G' dual-engine cards and thereby increase
the count of total streams per unit to two or three, making DB6
Multi the perfect, high-density solution for any TV station in need
of processing multiple streams simultaneously.
Each Transmission 3G card holds two multichannel processors and is capable of running two LM6 Loudness Radar Meters as well as two LoudnessWizard™ algorithms simultaneously.
Apart from the expandability of DB6 Multi, both versions are
identical, featuring the same high-quality hardware as well as the
same powerful software algorithms.
Working with 3 SDI Streams
The flexibility of DB6 allows you to work with up to 3 SDI streams simultaneously.
That's six engines of LoudnessWizard (UpCon/DownMix, ALC, Lip Sync Delay and True-peak Limiting) plus six LM6 (Metering and Logging) engines - all of which is sitting in just a single, cost-effecitve rack space.
16 Channels of Audio Measuring and Processing
A DB6 Multi with two Transmission 3G cards is capable of
processing, measuring and logging 16 audio channels.
Set up this way, your DB6 Multi will do its magic with 1 SDI stream containing 5.1+2 + 5.1+2 configurations.
In fact, by adding a third Transmission 3G card, you can use the same principle to process and measure no less than 24 audio channels simultaneously.
Trickle Down - Always Transmit 5.1 and Stereo
Since DB6 is able to run two LoudnessWizard algorithms, you can
be sure to always transmit in 5.1 as well as stereo no matter what
the input signal.
For example, if your DB6 detects a stereo signal, one LoudnessWizard algorithm will immediately upconvert the signal to 5.1, and conversely, if a 5.1 signal is detected, the other LoudnessWizard will downmix to stereo on the fly.
Whenever upconversion or downmix processing is enabled/disabled, it happens completely seamlessly and without artefacts.
At the output stage, you have 8 channels, which allows you to always transmit 5.1 + stereo at all times. Obviously, you also get log files for both the 5.1 and stereo side.
Now, if you add one or two Transmission 3G cards to a DB6 Multi, the same is true per SDI stream. For instance, if you have a fully loaded DB6 Multi, you can transmit 5.1 + stereo at all times - times three!
Pre and Post Measuring and Logging
DB6 measures audio loudness at both the input stage and the
output stage. Obviously, your audio will measure differently post
processing and it is key to be able to monitor both.
What's just as important, though, is having log files that reflect both pre and post processing for documentation and evaluation. With DB6 you always get exactly that. You can always take a look back in time and see what was coming into DB6 and what was being broadcasted.
Controlling DB6 with Icon for Mac and PC
We are proud to have taken part in defining several international broadcast standards by donating technology and submitting recommendations of which many are now integrated in these standards.
Throughout the world, legislation on loudness in television is being introduced as we speak. Not all countries rely on the same standard and all of them are ever-evolving, but regardless of your location and which TC Electronic Loudness-related units you use, rest assured that you will always be compliant with the latest revision of the broadcast standard that you need to conform to.
Defined by The International Telecommunication Union, the ITU BS.1770 recommendation is global and one of the most important broadcast standards as many other standards are based on it.
Our broadcast products supports all revisions of BS.1770, including the latest BS.1770-3.
The P/LOUD group, which is part of The European Broadcasting Union (EBU), has defined the R128 standard that applies to many European countries.
ATSC A/85 is specified by The Advanced Television Systems Committee (ATSC) and applies to US broadcasters. A/85 is rooted in BS.1770 Loudness and True-peak level and uses LKFS as loudness unit.
Defined by the Association of Radio and Television Businesses (ARIB), TR-B32 is a Japanese broadcast standard that builds on ITU BS.1770-2.
In the Press
Our history in digital audio dates back to 1985 and as pioneers in loudness, we took part in research studies and the definition of international broadcast standards right from the start.
Over the years, we have even donated technology that is now part of these open, international standards.
That is why world-leading broadcast magazines often invite us to share our knowledge with their readers.
