Re: ABC news audio alerts like NBC blackbox voice alerts

No problem. We run the feed through a compressor/limiter: there's an enormous variation in level, depending on who is speaking and how excited they are. Dierdre has come close to launching me through the drop ceiling on more than one occasion with her "ATTENTION STATIONS!". :lol:

Re: ABC news audio alerts like NBC blackbox voice alerts

Yes, ABC sends voice alerts on the NewsOne live channels: you should find it on the third or fourth audio channel of any of the NewsOne services. On our Scopus dual receiver, it shows up on the "Aud 4 Right" pigtail connector.

Re: Leitch Panacea reclocked outputs

Well, glad the software worked out. That's weird about the 720p/50... all I can suppose is that there wasn't a lot of call for that format at the time, and nobody picked up on it. Sigh...

Re: Leitch Panacea reclocked outputs

I don't think you can just turn off the clean/quiet switching, because it's an entire sub-module. You might be able to remove the sub-module, though... I've never tried it. If it's like the Evertz Xenon, if you remove the clean switch module, you need to replace it with a passive board to complete t...

Re: Leitch Panacea reclocked outputs

I just found what I believe is the most recent version of Router Mapper -- 6.16 -- and uploaded it to a Google Drive folder. If you PM me with an email address, I can share it with you. Router Works, if I remember correctly, hasn't been used since about the X-plus series... but I'll keep looking. Ar...

Re: Leitch Panacea reclocked outputs

The HSCQ version of the Panacea needs to have a reference signal feeding the external sync input; it may be either black burst (525i) or tri-level sync in the same format you are switching, and your video feeds need to be locked to that same reference within a certain time window (if I recall correc...

Re: 1080i Conversion for Broadcast?

1080p60, definitely. Everything else will look oddly jerky when played back in i60. Bear in mind that broadcast television in the United States does not currently support 1080p -- just 1080i and 720p. You can think of i60 as a sort-of odd compression technique that has as much motion as p60 but occ...

Re: Identify mic types

Here's a way to tell empirically without taking the mic apart: 1) Some condenser mics have built-in battery compartments; not so for other types. If you find a battery, it's definitely a condenser. 2) You will need a mic preamp... make absolutely certain that phantom power is turned off, as it will ...

Re: DX50 air flow switch

That's strikingly similar to a problem we had with one of our Harris Diamond transmitters (DTV), where the air flow sensor would occasionally cause a shutdown for no good reason. The plastic plunger switch for the rear panel interlock was also flaky, and had the same effect (nothing like having two ...

Re: RDL ST-SSR1

It might possibly work, but RDL categorizes it as analog gear on their website. I would be concerned about what happens at switch transitions, since this product is intended to perform a crossfade, which will yield corrupt data during the transition. My inclination would be to use an ordinary DPDT r...

Re: X-Y protocol??

Problem is, it told the computer it supported 1080i/60. Not 59.94 -- 60.00. When connected to the computer, the computer refused to output 59.94. Monitors & the router didn't care -- but the control room switcher & video servers sure did.ough times...) The microconverters we're using tell the compu...

Re: MPEG1 Audio Layer II vs. AAC which one is better?

I should think that the audio encoding format you choose depends on where you are located. I infer from your question that you are not in the United States, where the ATSC standard calls for Dolby AC3. MPEG1 layer 2 (also known as MP2) is somewhat older, is less efficient, and is less flexible -- fo...

Not a fan of the Cobalt stuff. Had way too many failures, particularly with their crappy power supply design. Interesting.
