  1. That would not be possible. All audio clocks have to be locked to the transmission bit stream or bad things happen.
  2. Everything resamples the AES from a super cmit. There is no way to synchronize it with an external reference.
  3. It would be best for Simon Hayes to comment on his wired and wireless use of super cmit. We have never had anything but praise for the Super cmit/ TRX743 combination. I am sure you had a problem with something (maybe the recorder aes input?) but digital transmission of a Super Cmit with a TRX743 is a great combination and to my knowledge the only AES42 wireless microphone transmitter.
  4. Constantin: The TRX743 and TRX742 can only pass the digital output of the mic to the receiver nothing more or less. If it did not sound right then there was a problem somewhere else like in the Mic or mixer for example. Simon Hayes has been using the Super Cmit with 743 for years .Hopefully he can chime in. Also the signal can never become noisy as it is a stream of 1s and 0s. Its either there or its not.
  5. I think it might be about 24 hours. I can do a test if it need to make a decision to use it or not. Glenn

    Zaxcom Aria

    I think you will find the ARIA is in its own new category of location sound mixer. Going from bag to cart with 8,12 or 16 faders with the elimination of resistive faders that are not designed for location use sets a new standard for our industry. ARIA is more than a mix surface with keyboard interface and USB port for the GUI interface. Power consumption is very location friendly at .15 amp. We will start delivering soon.
  7. There are 3 impeadace settings in the audio menu. 10K is default. 2.5K will be the lowest noise setting with a bit of low frequency roll off. 6061 will have a 10 dB higher noise floor than the 6060. For the lowest noise from the mic the 6060 is the best choice for our or anyone’s wireless. All lav mics have self noise as the dynamic range of the mic is limited to about 106 dB. Without companders or noise reduction software you eventually will hear it if you are in a quiet enough environment.
  8. The ZMT4 has been updated since it’s initial release and now lasts 7 hours with a Lav and 5 hours running a 48V mic. This time is increased with Power Roll a patented feature. I like to think of it as a no compromise transmitter that can go through the entire day with only 1 battery change at lunch. These run times are at a full 50mW power level, recording, Transmitting and receiving Zaxnet all at the same time.. Because of the efficiency heat output is almost undetectable under normal usage. ZMT4 is also about half the size of most digital transmitters.
  9. Mattias the ZMT4 runtime is 7 hours minimum at full 50mW power. It was 6 but we picked up some efficient with some hardware changes. We have had customers reporting 7.5 hours on a regular basis. This of course generates very little heat output due to the extreme efficiency. This is more important for us than others as the ZMT4 is roughly half the size of most other digital transmitter.
  10. Zaxcom products are very low power due to the obsessive need I have to use extremely high efficiency power supplies and to use the lowest power components where possible. We also use relatively low power DSP processors running our own operating system that is much more efficient than Linux or MS OS.
  11. Come on Michael. We will bring a new product just for you 😉
  12. Since the original post we have added the URX50 and URX100. Each monitor receiver has independent delay settings associated with independent channel settings. In this way a monitor receiver can be set for one channel with delay for monitor viewing and a different channel for live viewing with no delay. It can also be remote controlled. In my opinion delay devices are terrible because no one delay is right for everyone listening and viewing.
  13. The ZMT4 is about half the size and weight of any other digital transmitter and of course has the 12/48v supply. It lasts about 5 hours when set to 48V. It allows the pole to weigh less than a cabled equivalent. We would be happy to arrange a demo so you can listen to the audio quality. With Neverclip I would think you would find it second to none. And when you don’t need a boom it’s a extra super tiny bodypack with 7 hour run time and recording. Power is set to 10 or 50mW with no intermod issues.
  14. Our "leading receiver" the 4 channel MRX414 is a slot mounted design. Not to be confused with the "Super Slot". Yes it is difficult to make a 4 channel slot in receiver. Our digital receiver draws under 1W per channel. The typical slot is too limiting because of its limited power supply, poor ability to dissipate heat and limited room for RF filters that in our case requires physical space. Slots that were designed for single channel FM receivers in the 70s and 80s are needlessly limiting now that the market for slot type receivers compatible with broadcast cameras has all but disappeared. It will be interesting to see what Shure has done to get from about 8 watts per receiver down to a bag usable power consumption.
  15. The 6 hour run time is kind of a minimum. Better batteries and power roll will get you closer to 7 hours. If you can do without Zaxnet you can add about 1 more hour as well. The 6 hour figure is typical.
