  1. New from Rycote: Looks interesting

    Tac!T "The Rycote Tac!T (pronounced "Tas-It") filter is an in-line, active "third-order" (18dB/octave) filter with a "knee" at approximately 60Hz. This enables it to pass, unaffected, virtually all of the desired audio, while massively reducing wind and handling noise, and floor transmitted vibrations. The energy in these extreme low frequency and infrasonic sounds can be very high, and if not attenuated, would otherwise cause overloads and disturbances across the entire audio spectrum. The Tac!T filter draws its power from the P48 phantom supply while also passing power on to the microphone. It is electronically symmetrical and does not disturb the intrinsic balance of the microphone circuit, nor does it introduce any signal loss for normal programme frequencies. A key feature of the Tac!T filter is that it fits entirely within the body of a Neutrik XX-series XLR connector. It is not switchable, and the electronically buffered circuitry ensures that its performance is consistent for almost all phantom-powered microphones and preamplifiers in general use. Tac!T is a fully symmetrical balanced 3rd order filter. It is has a DC path through it so that it can couple phantom power as well as signal. What is the current draw from the recorder's or mixer's P48 supply? Current draw is ~necessary~ for the circuit to operate - the device will not work with dynamic microphones that do not pull current. The actual current draw varies with the load used so it is not possible to give a specification figure for it. The circuit demands are very low and with IEC 26815 compliant P48 supplies it is very unlikely to cause any problems. With excessively hungry microphones (eg those that suggest they need the full 10mA available, such as Earthworks), and phantom powering that cannot deliver adequate current, or is significantly under-voltage there ~might~ be problems. The likely outcome is under-performance of the microphone in terms of max SPL etc, or increase in self-noise rather than failure. Front-end filters on mixers are usually 6 or 12dB/octave, and these give a greater loss of wanted higher frequencies for a given cut of infrasonic or extreme LF noise. The steeper 3rd order filter (18dB/oct) is more effective. This is why the Schoeps Cut 1 and similar filters are liked by many recordists. In some cases internal filters are also fitted after a transformer and/or first amp stage - in that case these parts of the circuit can be overloaded before the internal HPF can act. Transformer inputs are particularly susceptible to infrasonic overload. Tac!T can be used in conjunction with internal mixer filters to give a dual slope HPF, but is perhaps of greatest value in applications such as camera inputs where no LF tailoring is provided at all. Tac!T FILTER TYPICAL PERFORMANCE Signal loss 0dB @ 1kHz, -3dB @ 63Hz, -40dB @ 14Hz Introduced noise (22Hz -22kHz) - 1.5dB Max signal level +3dBu (<0.2% distortion) SPECIFICATIONS Cable Length: 45cm (18") Cable diameter: OD 4.8 mm Connectors: Neutrik® XX series, XLRm3* to female XLRf3, Black casing, gold pins Cable Type: Ultra flexible Mogami® W2893 star-quad cable" Price about $100 should be available in 3-4 weels
  2. The Opposite of Mixing?

    Close enough for Government work.
  3. MKE2-5 to XLR

    Red goes to pin 2, Blue to pin 3 and shield to pin 1. You can't power a lav with 48vp if that's what you're trying to do by using an XLR connector. Lavs normally run on 3-5 volts supplied by a wireless transmitter. 48v phantom will damage the MKE2.

  5. Updated Forum today

    No not those numbers but the number of a posting in a thread.
  6. Updated Forum today

    Would be nice if the post numbers were included in the update.
  7. Miami best blocks

    Miami is RF central. To prove it, you throw a slice of bread up in the air and it comes down toasted. Basically there are no guarantees on clear frequencys at any given time. If you need any equipment or tech support when you're here give us a call. (Production Sound Solutions 954-289-4770)
  8. Alteros Wireless (a new branch of Audio Technica)

    Not through walls or around corners, etc. Doesn't seem very practical for field use.
  9. Senn G3 as Wireless Hop HELP!

    As has been said, "there are many ways to skin a cat" and while your way works for you, that's not how I would do it.
  10. Senn G3 as Wireless Hop HELP!

    There's something wrong if your TX is set to -50. Either your cable is not wired for line or your sending too hot a signal from your 633. Not sure what you mean by "full line level" output. You should be using the "0" tone from the 633 as your reference tone and adjust the TX input to give you about 75% on the TX meter. The RX meter should be set to about the same level. The 3.5mm TRS connector should be wired with positive to the ring and ground to the shield & the tip. The connector to the 633 should be positive to pin 2 and ground to pin 1 & 3. Now you have an unbalanced connection that will drop the 633 output into the TX by 6db as compared to balanced wiring. The way your working is like driving with one foot on the gas pedal & the other on the brake at the same time. Look up unity gain & gain staging for more information on how to do it & the advantages.
  11. Senn G3 as Wireless Hop HELP!

    I would bet that the TX input cable is NOT wired for line level into the TX. Feeding a line level signal into a mic level input is wrong in so many ways. That's why you have the TX set at -48 and the RX set at "0". It's all about gain staging. You need to either get the correct wired cable or set the 633 output to mic level out. Then you can raise the TX input level to -18 or so and adjust the RX output to about the same if you have a mic level setting on the camera. The cable you need will have the positive feed connected to the ring of the 3.5mm TRS input connector and a ground connection going to both the sleeve and the tip.
  12. The Postman Always Rings Twice (1946)

    I would venture that it was 35mm single stripe mag with the obligatory balance track.
  13. Ultrasone headphones for location work. Which ones?

    What he said +1.
  14. Hot pins?

    Is it PC to use that phrase?
  15. Hot pins?

    Traut is correct, less than 5 seconds is more than enough to melt the solder and get it to a liquid state. Tin the connector cup first then tin the wires then melt them together. The images show way too much solder being used in each of the cups which is probably why you have heat discoloration on the pins.
  16. Adapting Sennheiser G3 wired mics for use with Sony UWPs

    Keep in mind that Sony uses the ring of a TRS connector for audio & Sennheiser uses the tip.
  17. New Lavs for old VHF Lectro (M187)?

    The TA 5 on the PDR takes the same wiring setup as the wireless transmitters. BTW, there are no stupid questions only stupid answers.
  18. New Lavs for old VHF Lectro (M187)?

    Yes they work just fine with the VHF 185 & UHF SMQV units.
  19. New Lavs for old VHF Lectro (M187)?

    I wire all lavs for Lectro using the TA5 connector as per figure 2 in the chart above. They all work just fine wired that way including the old Lectro VHF 185 series units.

    Contact Larry at www.Versa-Flex.com he can custom make any type of rig you might need.
  21. Pro Sound NYC

    That's good to hear. I have no knowledge of the terms of the N.Y. sale only the sale of the Ft. Lauderdale office that we bought and for obvious reasons I will not comment on those details.
  22. A length of shrink tubing is a very good idea as it does not affect transmission or reception to any noticeable degree and as mentioned above it offers great protection. Do it, you won't regret it.
  23. Pro Sound NYC

    Yes. My email is Eric@productionsoundsolutions.com. Our website is a work in progress and is www.productionsoundsolutions.com
  24. Pro Sound NYC

    Everyone in the Topham family is just fine. Rich Topham decided to retire and sold the business. Jim & Andy bought the NY operation, the New Orleans office was bought by the managers who ran that office and I and my partner Ahmed Lugo who ran the Ft. Lauderdale shop bought the Ft. Lauderdale office. The New Orleans operation is now called "SoundHard" and here it's "Production Sound Solutions." Three separate companies all professionally staffed. All is good.
  25. Most antennas are cut to be optimal at the center frequency of the specific block they are meant for. If a block is say 500Mhz to 550Mhz the antenna is cut for 525Mhz. The closer to the center frequency that you can tune to the better your results should be.
