Hi All, Trying to program an Icom R5 using ARC5 in order to be able to listen into wireless frequencies for interference etc. Does anyone have lectro block tables in csv or excel format (personally looking particularly for Block 21). Thanks RL

Firmware updated successfully, thanks for the help! Below the finished project: Ad-hoc 2-channel TC system with usb-pre2, sta042, zfr100, timecode buddy wifi master, and BDS, with NiMH battery pack.

Dear Glenn, while I have your attention, could you post a link to the latest firmware update for the ZFR 100, I could not find it on the website? Thanks RL

Hi, this is great news re the transformer. Thanks for helping out on this. RL

Martin, I always try to make an effort ...

Hi All, Having read previous entries I understand that the Zaxcom STA042 is actually AES 032 device expecting a 110ohm signal. Does anyone know whether it will work error free with a 75 ohm spdif signal (source here is a sd usbpre2)? If a 110 ohm signal is necessary, will a simple Neutrik NADITBNC-MX 75 Ohm BNC F To 110 Ohm XLR M Adapter do the trick, or is an active sdpif-aes adapter necessary? I called Zaxcom and they did not have any experience with this. Thanks RL

This ebay seller says this $10 Lemo plug will work: https://www.ebay.com/itm/171989556108 And for anyone looking at this later the answer to my first question is 0B.

Use the SD Wave Agent app to see if the file can be read, and what exactly its spec is, if the files were originally recorded with the R-88. Next step I would take is backup the recorder settings to the SD card (for restoring if relevant). Then factory reset the unit. See if the audio files work then. If you are trying to play back files not recorded on the r-88 there are many Roland 88 codec issues that will prevent that; this would explain why they can however easily be played on a computer.

Dear Rich, Going into the STA 150 would be stereo line out of a SD 302 for example. I have the remote audio CAX3FL3M12PAD cable which allows you to bring a mono line level signal into the mic input of the ZFR 100. Thus I can bring stereo line level via the STA 150 or mono line level directly in the ZFR 100. My question is whether I get better audio by sticking with the mono recording, as the Zaxcom codec on the ZFR 100 may have limitations. Thanks Richard

Hi all, Anyone have experience on whether the stereo recording using the STA 150 on the ZFR 100 will produce inferior recordings in comparison with a mono recording through the audio input? The bonus question is whether anyone has found out whether running an external DAC into the STA 042 results in any transcoding degradation in ZFR100 recording? Many thanks Richard

Hi, that is exactly the answer needed. I was not asking the manufacturer as often members have sourced affordable alternatives or work-arounds for usually very expensive cables. Thanks RL

Hi All, Having updated to the :Wave I would like to make its power cable. I have Switchcraft 761K for BDS and am looking for the appropriate 2-pin lemo for the :Wave. I have a source for these that needs to know if these are "0B" or "1B"? Any help would be appreciated. RL

Hi, The biggest problem using M/S is the susceptibility to handling noise. The figure 8 mic will pick up the slightest vibration. To record M/S well you need superb isolation. We use http://ambient.de/en/product/floater/ http://ambient.de/wp-content/uploads/2015/07/QFL_www.pdf as well as http://ambient.de/en/product/twister/ and cotton gloves on the boom when boomed, along with the best M/S windshield/suspension you can afford. In a doc interview situation we put the M/S mic on a stand using a boom buddy. We use either a AT4053b or AT4051b for interiors, 416 for exteriors, and MKH 30-P48 for the side. If time allows, we will use also simultaneously use Tram50s or Countryman B6s. Veterans may pooh-pooh the AT's but they have worked for us, and having flexibility in the M/S imagery by having the two capsules has been a must. I also do not see the benefit of using the 418 as you need to have a lot more variability in your Mid element to produce reliable results. RL

Thanks for the replies. Further digging revealed this information: Lavalier Power Supplies Lavalier Power Supplies come in a couple of different varieties. Some require you to use an internal battery, some require phantom power (12VDC, 48VDC or either), and some work both ways either with a battery or phantom Tram Negative Bias Power Supplies: Will operate only with the internal battery Tram Positive Bias Power Supplies: Will operate with either the internal battery or 12-48VDC Phantom Power. With Tram power supplies the positive bias version is the most versatile (giving you the option to use a battery or phantom power), but it is also a little more expensive. So if the TRAM power supply will not work with phantom power it must be negative bias. http://www.trammicrophones.com/sale/general/bias.asp

Hi All, At the risk of sparking derision from the veterans, I have three Sonotrim lavs (all with external powering units with battery compartments). How can I know whether they are positive or negative ground when run through lectro wireless units, in order to ensure that they are not out of phase? I also have an equal number of TRAM 50's also with external units, some with battery compartments, some without. The question would also extend to these mics, and mixing them with the sonotrims. Thanks RL

Hi Philip, I fired it up and it seems to work fine. I did not seem to have any problems on that frequency, although I tested it in a somewhat secluded residential neighborhood. Not sure what I will end up doing with it. Do you think it is worth keeping as a back-up unit? Thanks RL

Call Atomos USA support, I have always spoke to someone in less than 5 minutes and the person always had the answer. And the questions were not easy that I had. Shot in the dark, see if the FS700 will output freerun int gen TC via SDI to the inferno.

Hi Simon, anything that would have been found on a spec sheet is of interest, including things like range, the noise floor that you mention, battery consumption, audio quality, transmission mode, dates of manufacture, caveats, and so on. Thanks RL

The image is of another unit identical to the one I have, which is marked with 473.6 MHz. Philip, did you ever work with these units? Thanks RL

Hi all, A friend just gave me an old wireless pair and I can't find any info on it at all. They are labelled as being in 473.6 MHz. Any info for the sake of curiosity would be appreciated. The picture below is of another one of these units that turned up at Gotham some time ago. Thanks Richard

Hi all, To counter a lot of confusion circulated on the web, here is the definitive answer regarding the fact that R4 Pro's gain control and limiters are all PRE ADC: I can't confirm the noise circulating about the Roland designs based on a functional block diagram which only intends to show the last gain stage and limiters are in the A/D chip. It does not show signal flow thru the A/D chip. If that noise was based on engineering then you would not be able to achieve 24 bit resolution and you would have have a useless limiter ! This is what I say in my Recording FAQ. Please note, in an effort to reverse the flood of bad info circulating in some recording forums, I suggest reading the technical specifications for the AK4620B series of ADCs used in the R4Pro and the R44 which is available for download from the manufacturer's website or the link below. "- Input PGA: 0dB to +18dB, 0.5dB/step (for single-ended input)" This is a digitally controlled analog Programmable Gain Amplifier that is controlled by the inner gain knob. Furthermore, the block diagram, supplied by the A/D converter's manufacturer, clearly shows the PGA or analog gain circuit ahead of the analog to digital conversion process in the signal chain. This is essential or 24 bit resolution could not be achieved. Furthermore a digital limiter post A/D conversion is useless.I strongly suggest you not set the inner knob to 12:00 and add gain in post, this compromises the quality of your recordings. It's equally obvious there is no digital gain stage in the AK4620B series of A/D converters but there is digital attenuation and a digital output mute function. AK4620B technical data sheet : http://datasheet.elcodis.com/pdf2/105/21/1052101/ak4620b.pdf Note on page 23 :"The IPGA is an analog volume control that improves the S/N ratio compared with digital volume controls."

Excellent suggestions. Thanks again. I have the Rycote Lyres, and now know about the other options if this does not work well. RL

I have to agree with the others re sdi cables, which do have to match spec for longer runs, particularly for something the length of a cable roll.

Hi all, Rycote USA does not have any more 19mm clips for the Rycote Modular suspension for use with the MKH 815/816. Their replacement is the Rycote Lyre Upgrade Kit 042223. Using only two lyre mounts seems to not really be stable enough for the MKH 815/816. Does anyone have experience with whether using 3-4 lyre suspensions will noticeably increase the amount of vibration transmitted to the mic? Thanks, Richard

This is a very cheap but effective solution for our documentary rig. The Smartview is in a 3RU wall bracket screwed to a Savage Universal 15.75" x 18.5" Air Flow Tech Table on top of some generic carbon fibre tripod legs; power provided by a custom cable from the Remote Audio BDS.
