Do you really need the antenna gain from a directional antenna? Why not just go with 2 dipoles?

Thanx Jean-Pierre for contributing!
Ideal maybe could be one helix (about 50/60m to "cover") AND one half dipole, antenna position will not be in the center of stage (public is 360 degrees, so I need to put at least one of them on a tower). But I'm not sure that could be a good idea, made that in receiving application, never did TRANSMITTING in the same open space. I don't think two dipoles give me enough S/N when talents go far and turn themself with bodypack in the opposite from antenna (18 dB additional loss). The place itself ISN'T RF quiet and I have other 16 IEM (center stage, with "normal" combining + antenna system) and 18 wireless transmitter, 60.000 people all around WITH WIRELESS BRACELET (433 MHz, but don't know transmission power), etc..

PSM1000 are 50mw, 10dB booster is just compensation for long wiring and passive split (and maybe not enough, antenna cable is about 5.5 dB loss every 20m at band used, I think I will need AT LEAST 30m, maybe 40, monitor world is UNDER the stage.

Ah: tons of led lighting and led FLOOR! Made some tests, looked good, but I know EMI will change with colors and other settings and can't be completely sure about them...

Uh. Going to take another coffee... ;-)

The 2017 Isuzu NPR 14' that was sitting on the dealer lot was over $55K


I don't know model they are, but in Central America, you can buy a manual Isuzu box truck (with nothing on the back) for about $14k and getting a box there is pretty cheap. They get about 30-35 mpg too. If they weren't illegal in the States I would drive some up... darn emissions laws! My brother-in-law has had one for about 10 years now, great little truck.

First of all the SRX812 and SRX835 have different coverage patterns. The 812 is a 90 degree box (one per side) and the 835 is a 60 degree box (so either very narrow coverage with one per side or two per side for fuller coverage).

Note: for the 835 adding the second box per side would not make it louder, it would just add coverage. Additionally having 4x 835's vs 2 812's would not be a significant increase in volume, perhaps not even noticeable.

I like the weight of 812 a lot, it is not overly heavy. They cross over nicely with sub.

The SRX800 series are fairly detailed, not quite like my listening system, but closer than many PA speakers.

Just an FYI, the SRX828 is decently large. Most SUV's and pickups would only fit one... maybe two. Not sure what you currently have for transportation.

Also, do you have a dealer? A good dealer will get you prices well below list.

If you do not have one Mike Pyle is a member of the forums here and he is a great guy to work with.

Don't you feel bad about this Craig? Good luck with Neubert, he should last a long time and keep you safe for many, many more miles of fun and adventure.

This client does mostly video production but this one looks lits got live audience component. Need A1, 2-A2s, audio system guy, as well as some lighting folks that can light for video and handful of vidiots.

Show is in Buffalo July 6-13. If anyone knows some good people or a contact person I should be talking to, please let me know.  My client is good people and I know itll turn out to be a pretty good gig.

Thanks

Brian

The gain setting on the ULXD & QLXD receiver units still adjusts the output gain of the receiver, it has nothing to do with the gain structure in the transmitter itself.

I am not certain how the Mic Offset setting affects this; Id imagine it changes the weighting of how the signal ranges between the low- and high-gain stages of the transmitter. I would think that setting it too high could cause distortion.

The Mic Offset setting is there to make switching between handheld and beltpack transmitters work better, especially in installed (ie no regular tech to adjust things) situations. In a nutshell it allows a specific transmitter to change its gain to be different from another transmitter, so that the system can be set up with relative even volume levels between different (handheld vs. beltpack) transmitters.

I don't entirely agree with your definition of gain in ULXD, though. We could say that the output gain reflects the output of the transmitter - compared to a Shure analog system such as UHF-R, where the output gain does not affect the front panel meter, ULXD gain settings *do* affect the front panel meter. I think to some extent the ULXD transmitter gain is sort of a Shrodinger's Cat thing, where there really isn't a specific level coming from the transmitter until the receiver assigns a specific dB setting. The article you linked says there are two ranges, but the hardware itself resolves to 1dB increments.

Shure Article

The gain setting on a CL/QL with Axient Analog does change settings on the transmitter itself.  I believe you have the option to adjust receiver output as well. Isn't 2018 tech pretty slick.

$30K  :)

Ford quoted me $47K for a new pickup front aluminum 14' box, Chevy was $48K for a new van front 16' aluminum box and they both had a 60-90 day delivery times. Neither had a tow package.

The 2017 Isuzu NPR 14' that was sitting on the dealer lot was over $55K

I only saw one nice used truck, a 2010 GMC 14' that had about 20k miles and had a lift gate. I prefer ramps as I need to walk stage decks up and down. They wanted $33K.

Most of the used vehicles I saw were at least 10 years old, had 100K + miles and were priced between 7K and 20K depending on how beat up they were.

I just finished loading the first show in Neubert. He is named after the old truck Qbert, short for Cube Truck and named after the old video game. The new "Bert" is now Neubert!

Just ordered more E Track. There is only a single row down each side and none across the front wall of the box.

Newest version of System Engineer is available for download.
In Off Line mode you will see the arbitrary FIR functionality.

AFAIK the processor Timo used is new hardware, not a firmware update on the older models.

And if you want higher tap numbers, look elsewhere.

BTW drawing straight lines on the screen is pretty tempting, isnt it  :)
