Omnia-SG

I just took on another small group where they are using Omnia 6's on the studio end and Harris digit AES inputs on the transmit side. :-[ I really hate the digit AES input and suggested stand-alone generators. Anyone using the Omnia-SG stereo generator? Does it have a 19 kHz notch filter? I know Mr. Foti is here once in a while. Frank? Anyone?

Omnia.SG does not have a 19kHz notch filter, but it does have a LPF to keep the SCA region clean.

To this day I have never been able to get the Omnia 6EX and the Harris Digit
AES input to sound right, have several Digits and 2 Omnia's, the audio is extremely
dull, no high end or sparkle. At Omnia's suggestion I have played with the pre emphasis on both units but cannot get them to mate satisfactorly.
I'm sure there are many other stations using this combination.
I have had to revert to the analog interface on the Digit and back to composite
to get audio that sounds excellent.
Time is running out as the rest of the plant becomes digital and we move into HD
very soon.
Any ideas?
 
The Omnia composite section is lightyears ahead of the Harris Digit. Feed the Digit baseband and it sounds fairly good. To do all digital, find a Continental 802D, which has an excellent stereo generator/processor in it. Even feeding the 'emergency' baseband input on the digital interface of the Digit does a better job than feeding it AES3.
Perhaps Mr. Foti or Mr. Orban will undertake to sell them some code which works at some point in the future.

Problem with the Digit is they use a look-ahead limiter for final peak control, and that is what will dull the audio. Add to that, they employ additional low pass filtering, which is not needed as the Omnia has already performed the needed 15kHz filtering that protects the 19kHz pilot.

Make sure that you have preemphasis ON, and that deemphasis is OFF in the Omnia. The Digit should be set so that all emphasis is OFF, thus allowing the Omnia to provide preemphasis. Another item to check is to set the drive to the Digit's look-ahead limiter so that there is NO limiting occurring in the Digit.

But, as posted, you will achieve better results using the Omnia's stereo generator, and feed MPX to the Digit's SCA input.

Better yet, lose the Digit, and use a quality analog exciter (unless you do HD that is)
I retired two digits here. The Harris Superciter analog unit sounds great, as does the continental 802's and the BE FX 30/50 etc line.

I'm only a fan of the digit when using standard composite in. I've had good luck there.

In one market, we had a digit running AES into it, we had no option but to run AES to the studio.

So, once we replaced the digit with a Continental, MUCH better audio. Plus, I swear we picked up about 10 miles of extra fringe and cleaned up some multipath areas. No joke. This was noticed over the long-haul not just overnight, either.
 
I found that a good analog unit beats the digit, even running composite into it. I wonder whatever will I do with these digital doorstops? I wouldn't use one, except in an emergency, for anything I wanted to be proud of.

I had a Digit with the AES input module but junked it two weeks after it got delivered. I still run MPX to the site and could never get the right sound out of the "emergency mode" MPX input on that module, it just sounded flat and muddy. it also was real nasty in certain multipath areas on that station. I installed the analog input module and it was a world of difference, Omnia 6 combined with that and we are louder / cleaner then before.
 
My experiences were the exact same as No time for sleep, emergency composite input on the digital interface was unusable, sounded like bad AM.
We should all get together and nail Harris to the wall on this one, they are still
selling this unit.
I have a major Harris order that I might be willing to hold up to get some action.
 
took Harris off my radar years ago.poor service and high parts prices.the Harris Digit became the Harris DITCH IT..Harris knows how bad that unit is but pretends not to.The analog version was fair,but nowhere near the continental or BE products.Best exciter IMHO the FX-50.CD quality analog sound,amazing...
 
Can't really complain about mine, I've got 5 running and two of the stations regularly get complements on the quality of the station's sound. (All composite, no AES)

One of those is an original Digit before they revamped the look of the front panel.

I've only had a problem with one of mine, I had an intermittent connection on the analog input module to the exciter, the composite level dropped about 50%, I removed the mounting screws and reseated the module, no problems since. I also recapped all of my units to be safe as part of their Service Bulletin issued.

I guess YMMV .... :)
