  1. Let's talk about DCHT (Digital Camera Hop Transmitter) specs. Lectrosonics makes 3 digital wireless systems: DSW System Encrypted Digital Wireless System using DBa Belt Pack Transmitter ANALOG INPUT ONLY Sampling Size and Rate:24-bit, 48 kHz Audio Frequency Response:20 - 20 kHz, +/- 1 dB Digital Modulation:8PSK D4T Digital Hybrid Wireless Diversity Transmitter 2 or 4 channel operation line level analog audio signals and AES/EBU digital audio signals 48 kHz/24-bit audio, ruler-flat 20-20000 Hz frequency response and now just announced in 2019 DCHT (Digital Camera Hop Transmitter) The DCHT accepts two channels of mic or line level analog signals or an AES digital signal from a mixer and transmits to the receiver or receivers in a purely digital format. Frequency Response: 20 Hz -10.5 kHz ± 1 dB Compatibility Modes: • DCH (Digital Camera Hop) Digital Modulation: 8PSK Specifications subject to change without notice On Gotham Sound website they list: Frequency Response 20 Hz – 14.5 kHz ± 1dB On the manual's DCHT Block Diagram is a "Rate Converter" So that would mean the AES3 digital 24-bit/48kHz signal is getting SRC (Sample Rate Converter) to 32kHz inside the DCHT before transmission? DCHT Ok for most dialogue but not music. Opinions?
  2. I have a shoot there next month. Is there any update on RF Blocks ok in Costa Rica? Coffee Farms so probably way outside any city.
  3. I've also done this half a dozen times. Sony PDW-F800, F55, Amira. Using SD633, 552, 788T, 688 units. HD-SDI carries 16 channels of AES. The most I've seen available is 8 channels using a VCR such as a Sony PMW-1000 XDCAM SxS Memory Recording Deck but that is really just displaying 8 channels on playback. For AES digital in it is usually just 4 channels on camera, VDRs, if you use an audio embedder it will take up to 16 but you may require 2 embedder units to add audio to 16 channels since each one can only add 8 channels. Some really expensive units allow access to 16 channels of AES input on 8 BNCs such as AJA FS-1 frame synchonizer.
  4. The way I look at it is if you can use a camera's XLR inputs that conform to the AES3-2003 standard for digital audio @ 24-bit/48 kHz is you are just using the camera as a bit-bucket and no loss of quality. No awful analog circuitry to introduce noise or low bit quality A-to-D converters used in the camera itself. With 24-bit you don't even have to worry about low levels since the A-to-D converters are in the sound equipment not the camera and thus bigger dynamic range (without limiters if desired.) With a mixer/recorder like a SD 688 internal digital router you can send any Prefade or Postfade ISO or mixes to any of the 4 AES tracks. With a wireless system like Lectrosonics D4 you can send 4 digital tracks wirelessly to a camera. I wondered if the idea r.paterson mentioned would work (onboard mic goes on ch1 (xlr1) and aes 2 track goes to xl2(set to aes goes to tracks 3/4 on f5/f55) or if you had to have only all AES on both inputs. Good to know.
  5. I went from a SHURE FP12 HEADPHONE BRIDGING AMPLIFIER to the Sound Devices MM-1 for a boom op o over 12 years ago and it was better in a number of ways. first it wasn't just a headphone amp for hardcabled boom op. and I wasn't only providing mic pre from my mixer. I could do wireless boom. I agree with many of the others above for using as a boom good mic pre before a TX for wireless boom op. the low cut filter was nice but especially the limiter. For non-scripted corporate stuff I also use it when I only need 1 headphone at video village for a director/producer or if there is a teleprompter operator I'll set it up just for them instead of breaking out Comteks.. The sound quality is lightyears above a Comtek PR-216. Paired with a slightly nicer pair of headphones than cheap consumables that are broken in a matter of weeks it sounds good and runs on 2 AA batteries.
  6. If a cameraman has the kit and is just hiring me as labor I bring my harness and headphones, toolbelt. I view them all as personal tools. No my toolbelt is not like a 1st AC bag kit. Keeping a few things in my bag of tricks like a Shure A15AS Switchable Attenuator XLR, a couple XLR turnaround & BNC barrels are lifesavers, and as an A2 a Whirlwind QBOX Audio Line Tester I live in NYC and on a labor-only day take public transportation and it's not like I am bringing my full kit and leaving it in my car parked at location "just in case" for À la carte item rental. Just as Wandering Ear mentioned it's also not my preference to have someone else's sweat-stained smelly harness I am expected to wear. If I have used their kit before & know and they have absolutely no clip-on velcro straps for cables, snake, headphones I may bring a few to make my life easy if it is a run & gun day. If it is a production /crew company it's also pretty similar but not too often do I come across these gigs. If anything is not working in their kit I do the gig with what I have, label the items as NG, and label the case as well, and usually email them listing the items that are not working and then it is up to them to fix it as I have informed them. David Waelder I love this!
  7. This is a good way to get Direct Outs when the FOH soundboard doesn't have them or there is an automated system. Thanks. Making my own mix is better and if a lot of inputs and using a the Dugan & MixAssist or Zaxcom Nomad (Auto-Mix) tool on some mixer/recorders is also an option for a better mix anyway than most AV FOH mix feeding the P.A. system.
  8. For a video shoot when documenting an event with a podium or dais table of speakers: When asked to get soundboard feed from an AV company contractor at an event or conference and it is of a low quality we have choices but as usual it depends (mostly on time.) sometimes there is a active press mult box but often I'm the only one taking a soundboard feed. I wanted to see if others came up with better ways... If it is at a hotel usually it is just an analog MONO feed out of a mixer that is doing the amplified P.A. system for the event. Sometimes it is a setup and walk away room where there is no human monitoring the wireless RF mics, mixer, or P.A. system at all. It just may be a busy hotel with a low priority on AV or a very small hotel. Over the years based on experience I will come with every connector type to take a feed as it may be my only option to get something out of the board. Often it will have a low buzz or hum. Usually eliminated with a ground lifted transformer like a Whirlwind SP1X3LL Line Level Splitter. A big issue for me is when the Audio/Visual dept. sets up the audio for the P.A. only inaccurately and has very low micpre levels and overall levels feeding the speakers as well as the feed they give you. Since they leave open all the faders at all times the noisefloor is close to AM radio reception noisefloor. These are situations with 3 guys on lavalier mics or a handful of handmics used as table mics without goosenecks and the FOH A1 has never heard of noise gating. In the room PA it may sound "okay we can hear them talking" but on our headphones when you have a all-day event with 2 or 3 sessions throughout the day it is numbing to listen to. Another major issue is RF Coordination in advance with the event organizer, contractor AV company, sometimes liasoned through a hotel AV department, actual A1 Front of House guy getting your request in advance for just a couple frequencies so he can coordinate on his end and ideally assign you 2 frequencies and 2 backups if you are being required to take a wireless board feed if they will not allow you to run XLR cabling for safety reasons or time reasons. Another way I can eliminate the low quality feed is by being able to split the microphone(s) at the stage bypasses their preamps low level and any ground loop issue coming out of the FOH board. I would use Whirlwind SP1X3 - Mic Splitter on each mic cable before it goes to a snake. This is fine with just a couple mics but problematic when there are 10 mics from a table of speakers. This gets a little hairy if you are there to document the event but not there for the entire day. Usually I will take their feed and if I have time also take a split of the podium mic myself if I can. The politics sometimes make it more of a challenge since it is their sandbox and equipment. Sometimes I am also able to take a Direct Out from their mixer for the podium mic only and then I have that clean as an ISO without the powerpoint sound FX and any music from VDR playback videos, or still low playing walk-in music. Sometimes I will discretely place a boundary mic up on the podium as a backup mic. And if none of that is possible I will run a lav mic up the gooseneck of the podium mic and into the podium mic's foam windscreen or underneath the mic with my own windscreen. This gives options when a terrible sounding soundboard feed is offered. Usually you want to have a crowd mic MONO or stereo for all applause. How else do you guys solve this problem?
  9. Agreed. With the social media from SD stating "between 633 and MixPre-6" it puts this mixer/recorder/interface really for bag work. I don't think the people buying this are going to setup a cart and it becomes an interface for a computer-based recording rig running Boomcorder or Metacorder with a middleware software mixer that most interfaces offer for musicians such as MOTU or Focusrite, and use a MIDI or USB 100m linear fader 8-fader console to make a mix. Can they? Sure but it seems like a patchwork way of doing it a decade after Boomcorder was a cheap option of multitrack audio in the field. The location of the _ONLY_ media card is underneath the recorder (when in a bag) . I suffer through this on a 552 unit that I sometimes use. I curse the designers EVERYTIME I insert or remove the SD media for it's location and having to unplug cables...SD will surely come out with a mixer control surface with faders for this internal digital mixer that is USB. The SD website doesn't have the User Guide up yet until the unit is released but how it is categorized on their website says a lot. It is under the RECORDERS section, not under the Mixers with integrated recorders. At a cost of $1799. MSRP with only an SDHC/SDXC card as sole media the option of Auto-Background Copying to a USB thumb drive is better than nothing but it sounds like a 2nd recorder would be better if you are at a sound cart. "change metadata/track names etc. after a file has been copied?" This would be an issue if the SD card failed or became corrupted. Since SD categorized this as a recorder what other options are out there? older bulkier units but with the same or better specs such as AES digital inputs/XLR-4-pin POWER INPUT which would be good as a backup 8 track recorder. Tascam HS-P82 8-Channel Field Audio Recorder $1999. Roland R-88 8-Channel Recorder and Mixer $1995. and extremely low cost portable multitrack recorders like Tascam DR-680MKII 8-Track Field Recorder $749. Zoom F8 Multi-Track Field Recorder $999. While I love SD user interfaces, I also really want a feature like Zaxcom's Neverclip. You really need 2 media rolling these days. The high end guys all use 2 separate recorders. The market the product is after are not high-end guys, thus needing 2 CF or SD media cards in the same recorder at least. There are many price points and products from SD now and they are coming under heavy competition from companies like Zoom and I wouldn't be surprised if Behringer entered the portable multitrack audio market with an announcement at AES this month.
  10. real-time graphics & interactive: a new dimension in storytelling virtual reality, augmented reality. Lucasfilm and ILM have launched an interactive unit see the 2:30 length video here: ILMxLAB Launch https://www.youtube.com/watch?t=36&v=7T9Dv1aLMbw so very cool stuff with real-time interactive graphics in the Star Wars universe. This is the next type of gaming as well as next type of narrative-based storytelling for CG-animated TV shows and movies like Avatar (2009) but the graphics done in real-time during production. The actors recorded with lav mics wearing motion capture suits... from a Hollywood Reporter article 'Star Wars' Virtual Reality Experiences One Step Closer June 12, 2015
  11. I really enjoyed being able to go and meeting some older and new guys and always talking shop. Thanks for organizing it Alex!
  12. I also agree. Even on the features I've done ranging from $500k-1.5 million budget non-union it helped. I have also been asked by other mixers who were going from one show to another with no time off to do the paid location tech scout for them a couple of times. In NYC that is one 15-passenger van with above the line and key dept. heads along for the ride. I've taken notes and some digital still photos (wide shots) at each location and email it all to them. It is what I would want myself if another soundie were scouting for me. For some of my TV work one client where they do paid location scouts the day before production on a 1 or 2 day bigger shoot with a crew of 20 where it is also non-union and I have a great relationship with the DP who I got the job through I have some discussions with him about camera and lighting creative ideas too (since we are close) before he talks with his gaffer. Since most of our work together is a 3-person crew anyway where i assist with engineering, grip, lighting on the small shoots. I have also been able to have enough time to order additional specialized rental sound equipment based on those days for our needs. Even though the location is locked in I am able to ask that we move 100 ft away from a loud noise source or something. This is on a job where we have 1 or 2 putt-putt generators for lighting...
  13. Hey guys, I wondered how often do you feed videocameras AES inputs? Since the cable runs are so far from Production Sound Mixer to camera a 110ohm XLR cable isn't exactly Canare Star Quad cable with breakaway snake. Sure With 110 ohm cable, the theoretical limit is around 100 metres for AES digital audio. I know on some jobs over the years I wish I had access to a SDI Audio Embedder for a video line cut on Digital Betacam or HDCAM VTRs to have it all on one tape instead of analog feeds of ISOs to all cameras. Or even having AES outputs at the time which I could route various inputs to for 8 audio tracks on a VTR next to me. I've done one job about 6 months ago where I was near one of the 4 cameras (no line cut) on a commercial and fed out of a SD744T 2 AES channels down 2 BNC cables over to the camera and then with an adapter BNC-to-XLR adapter and used short 110 ohm XLR Apogee wide eye cable for the camera input. It's a great feeling knowing that I can feed a 24-bit uncompressed LPCM to the camera and it will record in 24-bit without going through the analog circuitry. it was one of those one take kind of things and they wanted backups. Instead of getting 2 744Ts I suggested putting all 4 tracks on the Sony F-800 camera. The client was happy and it saved them money and they had a backup. Are you guys starting to use your recorder's AES outputs to feed the Sony cameras more often rather than just LINE LEVEL XLR? Sony has had them on cameras dating back to 2004 with the PDW-510 XDCAM. With the Lectrosonics D4R & Zaxcom QRX100 receivers offering AES output sure you can feed 2 or 4 channels of AES input on the camera via wireless hops (on reality/documentary/feature film). With the cost of 788T and Nomads (and their size) it is really a no brainer for production to just have 8 or 10 tracks as a poly WAV file rather than only 4 tracks of audio on-camera. Are more productions requesting 4 channels of audio on cameras? mostly reality-tv genre shows?
  14. This. I've wanted to have a discussion on similar subject matter. Alex brings up If someone on a shoot who is young is genuinely interested in asking about camera or sound on a non-narrative TV set I will answer a few questions. I am not going to teach them the job. It is not in my best interest. It is not in the professional sound recordist community within my region's best interest. If a client asks me to teach a PA sound I will tell them one thing but not step-by-step. That is what classes and books are for. It sounds like your client just showed you the door because they want to be cheap rather than be loyal and know the value in which your fee comes with. You might just have to be unavailable in the future rather than discuss further based on the emails you and the company already traded.
