  1. The IFB option board for the QRX100 is now being manufactured. We expect to begin deliveries of the option board somewhere around the end of January. We are now beta testing the unit and the results are way beyond my expectations. Since the original feature set was announced we have now expanded it to include full Zax-net capability. This will allow for a single QRX100 with IFB option to be connected to a Deva or Fusion providing IFB transmission, time code transmission, wireless remote control and metadata transmission. This eliminates the need for a separate IFB100 transmitter to provide the same feature set. The QRX100 receives two separate mono or stereo transmitters providing analog and AES output of up to 4 discrete audio channels. The option board inside the QRX100 provides IFB monitor return audio transmission with time code and wireless remote control capability. When the receiver frequency is adjusted manually (or after a frequency scan) the transmitters are automatically adjusted to the new channel via Zax-net remote control. The QRX100 can also control the gain of the wireless transmitters directly from the QRX100 control panel, Deva, Fusion, Mix12 or Mix8 panel. In an ENG application the QRX100 will mount to a camera and receive 2 separate transmitters in mono or stereo and transmit a confidence return from a mix of the 4 received audio channels and an external balanced or unbalanced source (Camera monitor output). The IFB return is received in the sound bag by the TRX900 with stereo adaptor. ERX1 IFB receivers are compatible with the option board and are available for client monitoring and time code distribution. The option board can also receive time code from Zax-net providing a continuous time code output to the camera in addition to the 4 received audio channels. The thing I could not believe was the excellent range we got on the IFB return and the dead silence of the noise floor of the return channel. All audio processing, mixing and RF transmission are in the digital domain so no noise contribution is possible. This means that for the first time the camera audio can be monitored wirelessly without companding artifacts and FM distortion common to all ENG wireless and monitor systems in use today. The QRX100 is available now and the IFB option board is plug and play when it is available. Glenn Sanders President Zaxcom Inc.
  2. Jade lives at Zaxcom and has very green eyes. He came from a shelter like all of my cats and gets alot of attention at Zaxcom. If I could only teach him to write software ;-) Molly needs a hug all the time. Moo gets a drink from the only source that is fresh enough for him. Glenn
  3. I will go into work and get the tracking number Saturday morning to trace the package. Pro Sound instructed us to ship it UPS red. If you hear anything please send me an Email. Glenn
  4. It sounds like a touch screen problem. If you give me your phone number I will give you a call to see what I can do to help. You can send it to GS@Zaxcom.com or put it up here. Glenn
  5. The time code out of the Deva does contain the Zax-net signal. Since the user bits are free to be used for any purpose that’s exactly what we did. When Zax-net does not need to send any data the user bits contain static user bit data. When a Zax-net remote control command or meta data needs to be sent we put the Zax-net data into the user bit area until the data block is sent. The time code is SMPTE standard code compatible will all devices. The Zax-net commands are halted when the Deva or Fusion is in the time code menu so that a non Zax-net compatible slate can be jammed without misinterpretation of the user bit data. Happy Thanks Giving Glenn
  6. The IFB100 is the transmitter. The ERX1 is the receiver. I think you are asking about the receivers. Either way all Zaxcom IFB and wireless systems are 100% immune to cell phone and walkie talkie interference. Glenn
  7. We are getting close to releasing the QRX100 with the option board. The QRX100 has been out for the last 2-3 months. In finishing the option board we have been able to incorporate the full IFB100 functionality. You can have the option board fitted to one of the QRX100s in the Zaxpaq. You would be able to locate it on set to receive 6 separate transmitters. If you run the time code signal and IFB audio from the Deva or Fusion back to the QRX option board you will have full Zax-net functionality including remote control and virtual multi-track recording with Zaxcom wireless. Glenn
  8. Keep everyting off for best results. These functions are only for special applications. Go ahead and try them to see how they effect the audio. Glenn
  9. The Transmitter source is any TRX900 and will connect to the Micplexer via a cable. The Micplexer boosts the signal up to 250mW while providing 50 dB of attenuation for any RF emission that is 50 MHz away from the center of the block the amp is in. The receiver side has about 25 Db of attenation of the signal from the amp side. The Amp when not used is a negligable draw on the battery so it is always on and ready. Glenn
  10. Here is a link to a picture of the completed receiver package. This will receive up to 12 channels of audio from 6 transmitters. The full discription will be on our site soon. The unit is a bit smaller than the Zaxcom Fusion recorder. It should be available in a few weeks. Glenn http://www.zaxcom.com/images/MicPlexer.jpg
  11. Quote from the video: "Wired XLR always going to sound better then ANY wireless" (: I think this would be a factual statment if the word "Any" was replaced by the word "analog". We will have to get one to see if there is any RF sensitivity. Glenn
  12. Currently 64 gig cards do not work. We will be changing our card driver to support unlimited memory sizes. Glenn Sanders President Zaxcom Inc.
  13. While we can not be 100% certain what might be neccessary in the future we have tried to make a product that can adapt. Zaxcom Wireless is currently programmed for 3 modulation types. US mono, US Stereo and EU mono. Nothing stops us from developing new modulations and updating the software to impliment them. Of course recording, remote control and no intermodulation are also current features. Glenn
  14. ; their current units are not yet capable of all the tricks that Glenn mentioned needing for the future... Zaxcoms current product line is fully capable of all of the features that were talked about in the initial post. Glenn Sanders President Zaxcom Inc.
  15. A Discussion on the Future of Wireless Microphone Use It's recently been announced that wireless broadcast frequencies will soon be open to white space devices, this makes the future of wireless microphone use nothing like what has come before. Interference from computer-based devices utilizing white space spectra will greatly diminish the range and reliability of today’s analog FM wireless microphones. These new users will be broadcasting wide band digital data that will appear to analog FM wireless as an increased noise floor. While it will not decode into audio, it will limit the usable range of wireless microphones. The problem is that the number of new users is unlimited and will most likely be many times the current wireless user base. At any given time white space devices could outnumber wireless users 1000 to 1 since these new users will be on a computer or even gamers using some sort of new Nintendo type product to play wireless against friends during school lunch. There is no other frequency spectra we can use that will provide the same reliability our current UHF allocation does. Frequencies above about 900MHz do not easily go through walls or bodies and are subject to dropouts. Lower VHF frequencies require large antennas making them unpractical. In the announcement it was guaranteed there will be two clear TV channels per location, but there's no way this will support the needs of our industry moving forward with traditional analog FM wireless. In order to use a large number of wireless channels simultaneously in the future the microphones we use on a daily basis must change. The following is what Zaxcom is doing to actively combat these future changes so our industry can handle this new reality. Since only 12 MHz is currently slated to be interference-free you'll have to fit as many channels of wireless into that area as possible. To do so, microphones must be free of the intermodulation artifacts that limit the usable amount of channels. Without intermodulation, RF channels can be evenly spaced allowing the available spectra to be used in the most efficient way. Wireless microphones will need to be flexible software definable radio systems, the type of system that can change its occupied bandwidth and modulation type at will to suit specific needs. For example, when 20 microphones are needed on a reality show they'll need to be set to the most narrow bandwidth, say 50 to 100 kHz per channel. This way two to four times the number of channels can be used together. If a few milliseconds audio delay isn't an issue, audio compression can be utilized to get the bandwidth down even farther, to allow even more channels per MHz. Conversely, if only a few microphones are needed, a standard 200 kHz channel can be utilized to obtain the best audio quality and lowest delay. Another key element is the ability to remotely control wireless over RF, not only for convenience purposes but out of necessity. For instance, during a football game there's a need to use large numbers of wireless both on the field and during the half time show. Remote controllable wireless gives you the ability to shut down the game mics while the halftime mics are enabled, allowing shared use of frequencies by multiple sets of transmitters. Internal backup recording will become a necessary safety net. When all else goes wrong, the production sound mixer will need to rely on the single thing that is guaranteed to deliver pristine audio every time since the reliability of audio transmitted wirelessly will almost always be subject to interference. Transmitting two channels over a single RF carrier. Where possible as with 2 channel camera links transmitting 2 channels per RF carrier cuts the number of required frequencies in half. Because of what the future holds, we feel analog wireless won't hold up in a digital world. Digital wireless has so much more to offer, just a few examples are digital dropout protection, minimization of occupied bandwidth, and transmission of two channel on a single RF carrier. Digital also offers the benefit of encryption, protecting the audio content from unintended listeners. Audio that sounds just like a hard wire is only a bonus! On October 30th Zaxcom is holding a seminar at Coffey Sound demonstrating how the Zaxcom Digital Wireless series is in tune with the future and available today. We hope you can attend.

  16. Hi Richard, Yesterday we verified a 4 gig SDHC Transend Class 6 will work perfect as well. Please Email me with your phone number if you need help and I will call you right away. It is odd to me that the 2gig cards we used to rely on are now not workable but it is good that we now get 4 gig cards that are good for the same money. Glenn Sanders President Zaxcom Inc. GS@ZAXCOM.COM
  17. No other seminars are planned as of this time. The seminar at Coffey sound will be put on the internet so it will be available to all. Glenn Sanders President Zaxcom Inc.

Zaxpaq12 is portable and designed to operate from a sound bag or sound cart. .
  19. Since different members of the production need a different delay an elegant way to satisfy everyone is to have the delay in the monitor receivers and not in the console or in seperate delay boxes. The Zaxcom ERX1TCD body pack style monitor receiver will delay the audio up to 10 frames and can be set individually. I know this does not help with a comtek solution but it could be somthing to look at going forward. Glenn Sanders President Zaxcom Inc.
  20. Each TRX900LT comes with a wire clip and an antenna. I can now update the running time spec to about 6 hours on a single lithium battery. The unit is more efficient than our original spec and gives off no detectable heat output. Nice clip picture Chris. The screws look so military spec. ;-) Glenn
  21. The Kensington card is too slow and can not take the data fast enough. This is why you get a few seconds and then the recording stops. You will need either the Sandisk or the Transend media. Be sure the cards you get are the real deal and not knock offs. Glenn Sanders President Zaxcom Inc.
  22. This is technically possible but I will not have an answer on this for a few weeks. If there is enough DSP processing available the answer will be yes if not then a selecton of either of the 2 channels will be way it will work. The TRX942 is busy receiving and recording at the same time and thats a lot to deal with. I have not tested the Sennheiser Mic but I will when the TRX942 is ready to go. Glenn
  23. The player will need to output TC and audio to the Fusion. Glenn
  24. You will need to record the file into the Fusion. You will have no problem if you record the file as it is played back from another device or a computer. Glenn
  25. This was released and I thought it was a really cool Idea. It worked well. I dont think it will make it into the LTS as our engineering department has bigger fish to fry. Glenn
