[BC] Digital STLs

[Bob Tarsio]

Clay:
I know I keep blowing our horn about STL interfaces but our new ATB tool box series product also does frame rate conversion expressly for this purpose. We designed the ATB-300 to be an STL interface for both wired and wireless STLs. The wireless STLs tend to not send all the AES bits which as was pointed out in earlier posts can cause problems downstream. We designed the ATB-300 to either ignore or to pay attention to the flag bits that tend to be missing in the AES stream from a wireless STL.  Another problem is non synchronous switching which we also solved with the ATB-300 product. Certain AES receivers will lock up with a non synchronous switch. The third thing we did was to make sure that the units can accept multiple sample rates and convert them to a standard plant output rate. in addition to the digital interface we are now offering a version of the ATB-300 product that will accept composite base band along with AES. So now if you have legacy STLs that you want to continue to use along with a newer wired or wireless digital STL switching between them is seamless. We convert the composite base band into a compatible AES3 output using a digital stereo decoder.
I also agree totally with Chip's comments. Broadcasters have the advantage even with analog technology to sound better than any MP3 delivered source. Analog FM and now digital FM technology can be competitive with those low bit rate services available on the Internet. Broadcasters should continue strive to put the best possible sounding product on the air.

I've got three stations here in Seattle that are
running DSP 6000's - very few problems.
Remember that their AES is 32K and not
44.1, therefor some rate conversion is required.
Usually the Orban 8500's deal with this with
ease.
