Author Topic: Non-Sync And Microphone at the same time? CP750 Gavin Lewarne Master Film Handler Posts: 278 From: Plymouth, UK Registered: Aug 2009 posted 06-27-2013 03:46 PM                     We are doing our first comedy night on Monday. I have set up our wireless microphones and everything is working fine. Only problem is the comedian has requested some music to play while he is being introduced and it is an integral part of his act at one point. Can the CP750 be set to have Mic + Non-Sync active at the same time? So far I haven't been able to make it work and am considering hooking up his music straight into one of the amps so mic is through 750 into centre and his music plays direct through amp on L+R?  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 06-27-2013 04:03 PM                     Time is short. Get a minimalistic audio mixer with Mic input. The CP750 can't do it. Something like this: http://www.bhphotovideo.com/c/product/421981-REG/Behringer_802_XENYX_802_8_Channel_Compact.html http://www.bhphotovideo.com/c/product/421979-REG/Behringer_502_XENYX_502_Compact.html or a rackmounted installation mixer: http://www.bhphotovideo.com/c/search?Ns=p_PRICE_2%7c0&ci=12297&N=4294548689&srtclk=sort BTW - Datatsat's AP20 has simultaneous NonSync and Mic capability, with suitable routing (NS to L/R, Mic to center). - Carsten  |  IP: Logged Joris Springer Film Handler Posts: 83 From: Almere, Flevoland, The Netherlands Registered: Feb 2007 posted 06-27-2013 04:21 PM                     Well replacing a CP750 with an AP20 is something I personally would not do. How about a mix panel where you just can connect your non-sync to with a microphone? Probably cheaper than replacing your CP750 with an AP20...  |  IP: Logged Gavin Lewarne Master Film Handler Posts: 278 From: Plymouth, UK Registered: Aug 2009 posted 06-27-2013 04:35 PM                     Time is too short to get a mixer panel this time so I will just hack the music into an amp directly. But I will get a panel ready for.next time ! Edit... A CP45 can do it can't it?  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 06-27-2013 11:14 PM                     quote: Gavin Lewarne A CP45 can do it can't it? I don't recall being able to do this on a CP-45, or any other Dolby Processor. Every time I've needed to do what you're asking (mic & music), I've had to use an external mixer of some sort & send the output to either the procssor's non sync or microphone input, depending on what extermal equipment I'm dealing with. I've got several small mixers. The one I find most useful in my particular situation is a small 8 channel Beringer "Eurorack" model.  |  IP: Logged Harold Hallikainen Jedi Master Film Handler Posts: 906 From: Denver, CO, USA Registered: Aug 2009 posted 06-28-2013 04:15 PM                        I can't speak for Dolby processors, but USL processors use the same analog to digital converter for both NS and mic inputs with analog switches in front. So, it's not possible to bring them up together. It's possible (though the GUI does not support it) to bring up mic and a digital input simultaneously (such as S/PDIF or Toslink). I think, though, that this would not really be practical in the field. You're probably going to want to adjust the mix between the mic and the music, and there are just not enough knobs on the front of a processor to do that. So, I agree with the other commenters here that a mixer driving the MIC or NS input of the processor would be best. There are various rack mount mixers available. I built some 30 years ago for use in TV stations (see TVA here . Good luck!

They can rent you any cables you need as well.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

With DSP based ones, I supposed most anything can be coded in. For venues where people have wanted voice-overs (e.g. in educations environments were one may be lecturing on the movie/clip being shown), we have added DSP so that the movie and PA share the system but, as Harold has indicated, the PA has separate mixers (often just an Automixer and sometimes right in the DSP itself) to handle the PA. Thus, the movie and mic levels are completely independent. Naturally, there are other ways of doing things.  |  IP: Logged
