This is a walk test of the new Lectrosonics DBSM / DBSMD Digital Transmitters comparing the new HDM and D2 modes. We are receiving two DBSMD transmitters, one in HDM at 2mW output, the other in D2 at 50mW and receiving them on two DCR822 receivers, one with shark-fin antennas and the other with whip antennas in a bag at ground level.
Please note that this is not intended as a test of audio quality and the focus is on RF performance.
The DBSM single-AA and DBSMD dual-AA digital bodypack transmitters are the latest in the long and hugely successful SM Series of miniature transmitters and are part of the Lectrosonics digital ecosystem.
For more about HDM (High Density Mode) please follow this link to the Lectrosonics RU-vid Channel • Lectrosonics HDM (High...
The units can be configured as either transmitters or recorders, with files stored on microSD card memory in the industry standard Broadcast Wave .wav (BWF) format at 24 bits, 48 kHz sample rate.

Great demo, but I would like to have seen the transmitters actually hidden on the body to replicate real world scenarios under film/television conditions.

Thanks for your feedback and glad you enjoyed the video! This is a comment we see pop up fairly frequently and we agree, in future we will be conducting further tests in real world scenarios. These tests are purely to measure the absolute range possible - and in the interest of fairness with our other walk tests we keep the format the same for all so we/you can draw comparisons. Keep an eye out for future videos - we definitely have plans for that sort of test!

Well done guys!

Very impressive

@amaobiajawara8323 3 года назад

Thanks for posting this video. If you don't mind me asking what antenna model are they using for the 822?

@RaycomTV 3 года назад

We are using the Lectro supplied whips in the bag and LNN2 passive sharkfins on the studio RX, the same as we use for all our walk tests.

@AZBohannon 3 года назад

I wish they kept walking the D2 range instead of stopping in middle of bridge when the HDM was done.

@RaycomTV 3 года назад

Actually the D2 was getting flaky at that point, it would have carried another 50m or so, but would be unusable.

@AZBohannon 3 года назад

@@RaycomTV Good to know. I am long time Digital Hybrid user, and was looking for a D2 walk test in comparison. The D2 range would appear short of “other” analog systems you have tested in the past. This is useful information, thanks for video and reply.

@RaycomTV 3 года назад

We did a Digital Hybrid vs. D2 walk test here where we walked further: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-q4bJPI8LnwA.html

@AZBohannon 3 года назад

@@RaycomTV Indeed, albeit without vector diversity which is unique to the 822. A closer match to the 411 in comparison.

@RaycomTV 3 года назад

We'll schedule a 822 walk without the distraction of HDM and the bag RX for some point in the not too distant future. We enjoy doing these so any excuse! :)
