What blimp do you use for this combo, i have the big stereo kit.but is really too big especially when working with bag.

My question is about using plugins, I  do mostly sound on a film set, and rarely I do some post-work for small projects, this helped me a lot to improve my job during the shootings. I've realized how easy it could be making a mess when cleaning up dialogues and mixing (mostly doing it at the same time).  I have mixed in the past mostly music and carried with me that background. High levels, transients massive, using compressors, never issues about noises and need to clean  rumbles, clothes rustle because everything was recorded in perfect situations. But when I approached audio film post everything was more complicated. I used plug ins on the single tracks and on the stems and had at the end awful sound and background noises and room tone coming out that could not hear before. this is only one example. 

so my question is what is a good approach when mixing and using any audio tool like denoiser or compressor and reverbs. Single tracks, on the bus where I 've routed into.  Any advice and link is appreciated

I have a made an A-B test between an Ek 100g2 and Ek 2000 both in range B with an SKP 2000 plug on with an Mk40 plugged. The only difference I 've noticed apart from the audio level (the g2 is unbalanced and 2000 is balanced) was a lower response on bass frequencies like a 50 Hz roll of was activated on it, but nothing so dramatic considering that I almost always use that cut generally.
Honestly, since I have 1 SK 2000, 1 SKP 2000 and only 1 Ek 2000 I need just a receiver to have 2 complete systems and already own some g2s receivers i same freq range.
What is your advice. 

I have a remote audio cable bought at trew audio, and tip is connected to the tA3 2 pin, and sleeve to the 1. So it is wired ad for mic input level on the g2-g3 trasmitter. But to feed audio to headphones wouldnt  be more appropriate to be on line levels?

What is the level of the background rf energy to work safely?

For example I set 650 Mhz as my working frequency  on my wireless mic and Rf explorer get an average  rf background energy of -55 dbm,  what kind of problems can happens, what should be the rf background energy level to work without risk of dropping?

Hi there,

 

RF Explorer internal frequency is correct in range of +/-2Khz if calibrated. The reason you may see up to 5MHz deviation is not due to frequency accuracy, but screen resolution. To understand how the screen becomes a limitation in your measurement is important to get the best out of the instrument:

• RF Explorer has 112 pixels to represent horizontal spectrum. Therefore, if you select a frequency span of, say, 1MHz, you get 1,000KHz/112=8.9KHz resolution per screen point. If you select a frequency span of 100MHz the resolution now becomes 100,0000KHz/112=892KHz, etc.
• For best results in normal operation, you should use a large span to start, say 30MHz in the picture above, to locate point of interests. Then move to narrow span to get higher resolution frequency read.
• If you need to read frequency with higher resolution, click ENTER once to enter Advanced Mode, then use RIGHT key to reduce span and, therefore, increase resolution. Or use FREQUENCY MENU to select a new center frequency of your choice, and a smaller span value.
• It also becomes very useful to pre-record your frequencies of interest with large and narrow spans, using Presets, so a single click can help you navigate through your frequencies of interest using high and low resolution as needed. For more details www.rf-explorer.com/preset

Hope this helps

Hi, ive just purchased an rf Explorer but i dont see any advanced menu option to get the span view setting.

Here's a pic of what the same window looks like (block 21) on the explorer and SRb. Main advantages to explorer is you can adjust the noise floor/threshold to see more detail on Y-axis, and you can set it to average the readings over up to 28 iterations of the sweep, helpful for finding intermittent or spurious interference!

I will let you know how the RTL-SDR works out, one advantage I see is you can tune the channels in FM and actually listen, which might help nail down the source of interference.

Ive got a sdr nooelec used with android smartphone app. Ive Heard the app Touchstone pro would work with and sdr usb dongle but they have Never  answered. The limit of the sdr dongle is the 2Mhz visualization.

has anyone tested and used the rf explorer WSUB1G and compared with the ucr 411 freq scan, specially when working with bag with several wireless mics from differents blocks and frequencies range i need a a wider rf scan, from block 24 to block 29 (included some sennheiser for camera hops in range b. 
Does it worth the money ? 
 

I own a block 26  smqv, a block 29 um400, and a block 26 um400a, can i use the venue 2 as receiver for any of these blocks?

Also, the antenna lengths on the sheet are not 300/MHz. They are what we measured using an impedance bridge with actual antennas on actual transmitters. This will be somewhat different from the theoretical values due to the fact that the transmitter is not a flat infinite ground plane and the SMA connector has the beginning of the wire somewhat above the transmitter. 

 

When the antenna is on a body, the length is not very critical anyway. If you have it within a plus-minus half inch, you are good to go.

this applies for all the devices or just for lectros?  (i ve never seen the theoretical values respected on other brand also).

the measurement is correct i printed with adobe illustrato, the line is 6.00 inches long (152.4 mm) and I verified with a ruler, as i told my antenna ( similar to a remote audios) with math calculation is going to be 2 centimeters longer than what lectro paper states. seems that lectrosonics antennas are shorter

I think anyone of you knows this document https://www.lectrosonics.com/phocadownload/ammkit_td.pdf
I am quite confused by the numbers, I need to cut antennas for a Sennheiser 2000 SMA modded in range gw (558 -626), and want to cut at perfect length corresponding at 590 Mhz, the math tells me that 300/590 is 50.08 cm:4 is 12,7 cm, but on this paper, the block 23 is 4,24" that is 10.7 cm, 2 centimeters less. almost 1 inch.

why?

I own a mkh40  bought when I used to work alot with orchestras, i own an MKH 30 too, used in a MS kit, (sound excellent with the 40).

i am considering to sell it (or exchange with a MKH 50) because since many years i do mostly the  boom op, in film - tv business. 

What is you feeling about it, I can't keep them both, i am wondering if anyone has experienced the 50 on big orchestras too with a 30, how it behave in music?

many times  in indoor location Ive felt  It was crucial a  better directionality, the 50 would be a better tool for me in daily job.

these are 2 ek2000, the nr1 doesnt have the diversity antenna connected while the n2 has it, does anyone have any explanation of it? i want to take out the second sma i shoulg go from the hole on the pcb and grounding  the sma connector on the case?
the previous images are all about the g3. 

these are 2 ek 2000, the 2 seems to be grounded while the number 1 doesn't, can anyone explain this? to wire a second sma, I shound take out that  grounded wire outside?

Should be fine. I did this with a Venue 1 Wideband using the RF loop out.

it is not wideband but only blk28- 29

in this scenarios with 2 active devices, a sound devices sl6 and a lectrosonics venue, how can I combine this 2, with only a pair of wide range antennas.

Ive seen this (https://www.sweetwater.com/store/detail/2X1SPLIT--rf-venue-2x1split-passive-splitter-combiner) but want to try to look for something cheaper.

the sl6 and the venue being actives, can the the combiner be passive?

I am making an A-B test between 3 sennheiser plug on, 2 sk 2000, and 1 sk500 using the same receivers, 2 ek 2000, and I I was rather surprised by the fact that the sk 500 seemed to be more efficent (at 30 mW than the 100 mW of the skp 2000, but the only reading of this was the rf meter on the receiver display. Have someone ever done a test like this and what is a better more reliable way to make it?

Ihave modded some g2 tx and rx but want to mod both the antennas on ek2000, where the  second sma should be welded at?  Thanks

Copy thanks, but having an sma distro  for indoor and or bag recording a pair of dipole antennas tuned on the middle of all my blocks  should give me at least a better performance of own whip antennas. What do you think?

The sna600 has a 100 MHz bandwidth around the center frequency (as printed on your antenna). So you're not really using the right antenna for this wide of a spread of frequencies. The roll off is gradual, but with a range of 512 mHz to 760 mHz that's a 250 mHz spread. Use a sharkfin antenna as that is wideband 

setting the sna 600 in "the middle "of those blocks wouldn't be as efficient like a 470 - 790 shark fin?

Whitney,

 

PSC does have a smaller unit that might work.

(http://professionalsound.com/specs/multi.htm)

 

p.s.

PSC has an awesome one called the MultiMax RF (http://professionalsound.com/specs/multimax.htm) I used this one on my last Reality Show.

 

p.s.s.

I'm a SNA600 fan too.. but you have to keep all the Lectro's in the same blocks because of the settings on the antennas.

 

 

 

Ive got lectros in block 20, 24, 26, 29. How should i set a pair of sna600.  Hss anyone tested the venue rf diversity dipole fin combo too ?

Hi,  I am upgrading my bag rf management and I came across in this discussion, 
Right now I've got 2 ucr 411 in my bag, and 2 -3  sennheisers g2/g3 with sma modded and wanted to use 2 antennas instead of 6 (4 on UCR 411 and 2 on G3s)

I have some questions:

why the active  antenna seems always to be the panacea of any rf issue, what i learnt is that for cable lenght below 8 meters there is no need to get boosters, since everything concerns the bag we are dealing with less then 1 meter. 

2 if using a rf distributors like psc multi sma  is always appropriate working with active antennas?

3 can I use the ZFSC41 mini circuits  with lectrosonics  and sennheiser g3 receivers?

Where would you say the tipping point is for when you need to add an amp to makeup the splitter loss? 4 receivers? I have a few of the mini-circuits 4-way splitters but I'm always hesitant to use them without amps. 

 

 

how do you supply an amp with those  spitters ZFSC41


thanks.

Active antennae need power. They will not work without it. They are a different design.

there no way to bypass the booster?

In case using them on bag and or with short cables maximum 1 - 2 meters with a rf distributor like psc sma, i wouldnt need a  active antenna, so in this case i can set them 0 db?

and what happen in case i want to use on only 1 receiver like a lectrosonics UCR411 it cant feed the antenna.
