    Hi Paul,

     

    Thanks for the update. Have you seen the video I sent through via my dealer? 

     

    Trev

     

    We're still waiting for your dealer to pass the video on to us. We'll chase them up. Let's take this troubleshooting off line now - there are too many variables to do this via text.

     

    Thx

    Happy to trouble shoot this with you offline. It'll have nothing to do with the wireless lighting control because NexLink is a protocol with its own proprietary command set and packet format.

    Feel free to reach out to me or Danny, Laura, Zach or Dennis at SD.

    Quick update on this, Trevor. We have clarified that this is NOT a NexLink control issue since transmitters are not powering off, they remain on and continue to record fine. This is mostly likely an RF issue which could be caused by a myriad of different environment or setup reasons. We need a lot more info before we can determine what the cause is. Someone from SD support should be reaching out to you pretty soon.

    So I'm 10 weeks into using the system .. mostly  happy.

     

     

    I'm having an issue with the a20 minis.. I'm finding that they randomly turn them selves off !  Happens maybe 5 times a week. Almost certain it's related to the wireless lighting control system.

    Had very minimal contact back from SD... would like to know if this is happening to others..

    a20tx has the battery life and features i love plus some very very nice ones like epaper gone are the days of sticking tape with number amd names on my tx’s. 
    When sd married audio ltd i was very happy as i expect this would result in great symbiosis. 

    now on a sidenote could we please revert that whole brexit shenanigans so the european SD  HQ would have its office in the actual EU 

     

     

    Sadly we do not have the influence to reverse Brexit:)

    They way I currently understand how gain forward works with a nexus docked onto an 8 series recorder is that the trim knobs on the 8 series essentially just become controllers for the output gain on the nexus. I don't believe you're adjusting the digital input gain on the 8 series at all.

    With Nexus docked, the 8-series trim knobs ARE adjusting 8-series digital input gain - they are not controller knobs for digital output gain on the Nexus. The Nexus output gains are set to unity (0 dB), then you apply whatever 8-series trim gain you need to bring the received signal to the level you need. Since the 8-series gain is digital gain for a Nexus input, there is no noise penalty. Of course, if you crank the 8-series gain super high (there is up to 60 dB digital trim gain available), you can exceed 0 dBFS and get digital distortion so you still need to set gains appropriately. You can get the same benefits of GainForward with Cantar or any other mixer - just set your Nexus digital output gains to a fixed nominal level (unity or more if you need more level), then connect via Dante or AES to your Cantar (or other mixer) and apply digital gain there. As long as the signal remains in the digital domain throughout the entire signal path, there will be no noise penalty.

    I own two A20 mini TX and a A20 RX alongside Wisycom systems. It's worth noting I mainly work on documentaries.

     

    I have to say that the batterie life is not really an "issue". In documentary too, people have to eat and rest, so I just swap at lunch time, like I do anyway with the Wisy's too.

    BUT, sometimes one have to change batteries on the field. Last time, in the speed of action,  I did swap the batteries in a hurry just before a take, without properly switching it off with the app first. . 
    When powered up the A20 mini TX back, all the settings were gone. I had to set the frequency and power with the app which is not always very responsive (on an iPhone 12) while the talent, a musher with his 6 dogs and the team were waiting for me. Quite stressfull.

     

    Other misadventure: on a previous shooting, I had installed the A20 mini on the neck of a salsa dancer. Great shape and weight, impossible to see it on camera with her long hair and she was vey happy to wear it..
    After a couple of hours, the temperature in the venue went quite high with all these dancers. And the sound began to "fade away" and get distorted. I thought it was the transmitter overheating and installed another one.... same issue. The problem came from the receiver. It was so hot I couldn't really touch it. When I came back home I changed the way the receiver was installed in my bag to allow an air flow and the heat to dissipate. I wasn't able to reproduce the problem since and the system is working flawlessly now.

     

    So, these two stories illustrate some of the challenges that we could be facing with the A20 in fast paced documentary.  On the other hand, I also had great success on a skier with the integrated recorder ( I am based  in Europe). To conclude, I'd say that these little transmitters are great tools to have, but you can not rely on it in each situation. For me, the weakest part of the system is the control only via the app. I have no doubt that the Nexus link is far more reliable and straightforward, but unfortunately, I is definitively too expensive for the kind of "bag" gigs I mainly work on. 

    Hi Henri - I believe all of these issues have been resolved and /or improved in recent firmware updates. If you still run into problems, we'd like to troubleshoot further with you.

    It has the same width than a SX-R4+ 😉 but I wonder how much power draw it has when used in the 8 RX configuration? Is it 20W?

     

    • DC input, 10 to 18V in, 3A minimum at 6.5 VDC
    • 11 W idle, default configuration

     

    Way less than 20W. About 12W.

    Is there "intermodulation coordination software" and "auto assign" of any kind included in ?

    Both of these things will come soon in future firmware update. FYI, to assist in frequency coordination, you can export the Nexus RTSA freq/dBm data as CSV file for importing into frequency coordination tools.

    Let's say we have onset the 888 + Nexus, 888 performing as back-up - plus the ability to output the channels to main cart (Scorpio or Cantar X3) via Dante. 

    You can do that docked or not. When docked, all 16 channels pass from Nexus to 888 via the expansion port and so can be recorded as backup on the 888. At the same time, those 16 channels can be routed to the main cart from the 888's Dante port.

    Anyway, starting to think that SD want to be in other market - industry since merge, but this is different conversation.

    Production Sound is still and will always be our primary industry.

    Just curious what kind of battery life people are getting out the the A20 TX.  I have heard 4 hours on a few videos, but  that is not acceptable run time to me, if that is the case.  Looking at upgrading everything soon.

     

    You can get up to 5.5 hours with 3x Lithium AAA batteries. Recommend using Long Range modulation as it allows lower RF powers to still achieve  good range.

    Hopefully the data is not offloaded to a giant profile in a server to make the algorithm better, but just something it can use for the coming seconds..

     

    All NoiseAssist processing is done in realtime internally in the 8-series ... This is a very complex algorithm  that  has taken a long and intensive development to get it to suppress noise effectively with only 1ms latency.

  13. The way to view NoiseAssist, is it's simply another tool in your toolbox which you can use when in a situation where you can't escape the background noise e.g. distant traffic or air conditioning. And like all processing (EQ, compression gating etc), do not over apply - it can then be very effective.

     

    It can be applied to ISOs or Mix buses or both.

     

    Paul

  14. Mano - you are correct! Blue allows you to create mixes independent of the pre or post fader gains feeding the main mix. This technique is often used for creating custom monitor mixes for musicians but could also be useful for creating personalized IEM feeds on set.

    Will SL2 have a set of analogue (or digital) O/Ps as well for use with recorders other than 8 series (for use with another recorder)?

     

    No. The SL-2 is powered by the 8-series via the interconnect.
