I've spoken with a few people and read numerous posts where this distinction is not made. I have a loose understanding of it and would appreciate those more knowledgeable chiming in to clarify. I've tried finding this in the ARRL handbook but am not sure what search words to look for in the index. From my understanding, RF gain attributed to an antenna type such as a helical(+14db) or LPDA(+4-6db) is totally different from gain needed to get back to zero on a receiver from couplers or long cable runs using a low noise amplifier(LNA). The antenna gain is similar to microphone pickup patterns and their "reach". A helical antenna radiates a field that is cone shaped( I th…

So I recently bought a second hand 416T and have noticed it seems to have a more self noise than I expected as well as not having as much gain as I expected. Not knowing if this is just a common 416 sound I recently got to compare it to another 416T and it is noticeably different. I pulled the capsules out and the 416T I bought second hand has a KS16 cap and the other one has a KS15. I am now thinking that my mic has had a replacement capsule put in but wanted to know if the KS16 cap is 48v? Just trying not to fry any of the components. James

Hey - I'm new into the sound world, and I got my first call for a sound job on the Red today. I know there are a lot of things that need to be done differently (that it does not have XLR inputs for example). I would REALLY appreciate any advice. I have quite sometime to figure it out. Thanks!

Hey all, I had another question about the Canter, this may seam like an amateur question but what would be the easiest (and wallet friendly) way to send a signal out to the director, for the moment. I want to send a signal I am hearing out to the director, and I don't have a mixer yet so its just the cantar X2, so what would I need to get besides the high cost lectros, or an easy temp set up that will work for now?

I have this old Micron tx 501 with a Sony mic but as the Sony is so big to hide I think I would like to change it to a RODE one as can change the cable with those so I can use it with Micron with its own cable. Now you older professionals might remember how to connect this combination. Tried the same as with Sony and didn´t get it working so I put the Sony back. The Rode cable is a nightmare to solder with bad eyesight at least... As a retired sound guy this is more or less for hobby, but if someone can help I would be very thankfull! Matti

Has anyone tried connecting the BNC output of a Lectrosonics Venue System to the BNC input on a Sound Devices SL-6? I want to share the reception my Venue System receives from my powered shark fins with a 688/SL-6 set up to expand my wireless setup on my cart. The coaxial run between the Venue System to the SL-6 would only be 50cm or so.

I saw this on another forum: " uses a ta5 input which is much more robust than the lemo plugs " while the TA type connectors are less costly, more readily available, and usually easier to solder up (due mostly to being a bit larger) I have always found Lemo connectors to be more robust than the TA type. I also prefer the Hirose connectors over the coaxial connectors for power connections, and the Nutricon's over XLR or other types for breakaways... Many products mention their gold flashed connectors as a premium feature, and Lectrosonics is still mulling over what power connectors to use on future products! Lemo pins (gold flashed) make better, more reliable connec…

Has anyone determined which wireless frequencies are most/least likely to suffer from occupancy sensor interference? The Leviton sensors operate at 5.8 GHz but I have run into what sounds like intermodulation problems in UHF.

Well, long story short, I am having trouble exporting sound files from a Korg D3200 digital recorder to my macbook. The files include a 1.4 gig 16 bit (44.1 khz) file, and the other is 24 bit (48 khz) and stands at about 4.8 gigs. Now i have two main problems, the first is that the transfer space i have available on the recording station is only 4 gigs, and i can't transfer the larger of the two files to my computer via USB. I need some way to either cut down on the track, or enlarge the transfer space without ruining or deleting what i have. The second came when i transferred over the smaller of the two files, but found it was a .DBK file, which i found out, after…

Hi, Does anyone here know of an adapter (or just the wiring scheme, if possible) to use my COS-11's (wired for Lectro) with a Sennheiser G2 transmitter? I made one for a Tram, but the Tram died (I never liked it anyway...) Thanks -Jason

Does anybody have the Neutricon pinout for the Betabox? It's the Ravencourt/Essential Audio/Audio Developments pinout for the Neutricon, not the PSC as I understand they are different. If anybody can help me with this it would be greatly appreciated. Many Thanks, John Perkin

Does anyone know; if a monitor only has HD/SDI input, will it be able to receive a 3G SDI signal? I may be purchasing a used Marshall dual monitor that has only HD/SDI but most likely it'll be plugged to the output of a teradek bolt receiver. Cheers! pablo

The left channel is interrupted once for 250 ms every 4 seconds. 250 ms later the right channel has two interruptions of 250 ms spaced by 250 ms. Graham's Line Ident Tone System (GLITS) is a test signal for stereo systems devised by BBC TV Sound Supervisor and Fellow of the IBS Graham Haines in the mid 1980s. It comprises a 1 kHz tone at 0 dBu (- 18 dBFS) on both channels, with interruptions which identify the channels. This arrangement has an advantage over the EBU stereo ident tone in that each channel is explicitly identified as belonging to a stereo pair. The EBU Technical Document Multichannel Audio Line-up Tone (Tech 3304) defines stereo lineup tone has havi…

I've bought what is marketed as pair of single lyre (19/25) (with modular adaptor & screws) in the 3 shore/stiffness variants (62/72/82) to use them in my Cyclone or an INV-7. For simplicity I'll only refer to 62 Shore variant here. Mine has product code 042255. There is a similar product, with the code 042250 marketed as pair of single lyre (19/25) (with premodular adaptor & screws). Rycote also offers a Cyclone Pair of Universal Lyre with the product code 042270. The lyres that came with my Cyclone and my INV-7 look exactly the same as those I just ordered (just without the adaptor). What are the differences between modular and pr…

I am about to be working on a project featuring some trainers doing high intensity workouts and the producers what to achieve the most even sound possible. We have done some of these in the past and we would run one lav and a boom, but due to the quick movement, changing positions, the trainers head pointing in different directions, the lav being covered or pressed into the floor for certain positions, the lav track is not always reliable. When they use the boom to fill in the gaps the sound is quite different and they are trying to figure out a way to get a more even sound throughout. For some stuff this round we will be using a countryman h6 headset, and this will el…

Good day my fellow sound peeps. Just a question.... I usually use the NP-F970 lithium batteries on my SRb receiver and it lasts a few days. Bought a NP-F550 today and just want to know what the average hours you guys get out of it?Or should I rather ask,at what voltage does the SRb switches off,if the battery runs flat? Thank you in advance
