The IQ filter stands for Intelligent Q.  The Q of the filter is the ratio of the filter depth divided by the filter bandwidth.  A Hi filter is very tight and low Q is very loose.  The IQ filter circuit analyzes the signal strength of the transmitter as it arrives at the antenna.  If you have a good strong signal, the receiver actually reduces sensitivity and tightens the filter (increasing Q) to make a very tight front end.  In doing so it is rejecting not only very close interference but some of the energy of the transmitter as well.  This can be a good thing.  For example, if you have a 1/4watt transmitter running and the scene starts in very close proximity to the antenna, you can run a risk of RF overload in the front end.  IQ filtering prevents that overload and makes the filter extremely tight.  Then, as your talent rides away on the chopper, the filter relaxes and the receiver sensitivity increases to capture as much transmitter RF as possible to keep range at its best. 

Now, envision a shoot on a very difficult set with lots of RF in the vicinity (the deck of an aircraft carrier on general quarters).  You can set all your transmitters to 1/4 watt for excellent capture and not worry about front end overload, even at close range - not only will you get good capture but you will also have very high rejection of the local interference sources that are slightly off frequency. 

IQ filtering is a dynamic, hands off automatic function based on signal strength - at its loosest, the filters are better than a VRS, nearly VRT like.  At its tightest, the Q exceeds any filters we have ever designed.  You can actually have the antenna of an SMQV at 1/4 watt nearly touching the Venue 2 receiver antenna with no overload. 

It's pretty cool - I think we finally found the correct ratio of Oreos, Twinkies and Coca Cola for the engineering staff - they did a great job on this.  


That sounds like magic!

For those of you who wanted a Dante capability, we looked long and hard at that (as Dante license holders) but realized the added cost would be an extra burden on those wanted Venue 2 without Dante.  (We would have had to use the Brooklyn 2 chip set which is capable a 32X32 matrix.  Dante does not have an 8X8 or 6X6, just 32 X32 , 4X4 and 2X2).  So, for this Venue 2 introduction, you can buy a Venue 2 and if you want Dante capability, we are offering a DNTBOB88 8X8 unit at half cost complete with the required cables to integrate a Venue 2 into a Dante network.  This gives you the additional capability of the additional two input channels for other gear on the cart AND the 8 output channels -plus the flexibility to use it elsewhere.  The additional cost would be equivalent of integrating the Brooklyn 2 into the Venue 2.  But you get additional capability for your Dante based cart beyond just the Venue.

We recently signed up for the Dante 2X2 and 4X4 platform for future developments.


Just curious, now that a fair few years have passed by, and Dante has firmly established itself as a standard for the sound department on film sets as well, is a Venue 3 with Dante coming?

Yes, it's called the DSQD.

Karl or Larry,

 

Does the DSQD employ the same type of IQ filtering when in digital hybrid mode as the venue 2? I’ve read through the whole manual and don’t see anything about that tech. 

 

That’s one of my favorite features of the venue 2 and why I bought it versus a venue 1 system.
