[BC] Re: Marti remote quality

Thu Apr 5 06:55:58 CDT 2007

At one time Marti in Cleburne offered an optional noise reduction system vailable for their 150-161,  450-455 mHz. and the 67 kHz. and 92 kHz. SCA Systems.

I worked for a station where the CE was very keen on the use of DBX noise reduction on the two Marti sysytems we used.   The noise reduction reduced the hiss and noise noise and made a real difference in the sound and the reduction of the hiss got rid of the rising noises between pauses caused by both the Marti's built-in compression and the stations compression.  The DBX was very specifics about input level sho we used a Shure Remote Amp driving the DBX the DBX was set to feed the MArti below its processing threshold.  All operators we urged to not over drive the Shure as it would affect the noise.

We also used a dual monitoring headphones at the remote sites, split headphones with one side off air if available,  the other side with the 67 or 92 kHz. SCA from our FM station that could be switched to any of three of the stations final audio to the transmitter with built-in ducking IFB from the talkback microphone in the control room.

On any shows involveing remote telephone calls the talent at the remote could hear the producer's cue,  "..next call from Mike downtown.."  then the talent would hear the call over the SCA channel.  The air signals were all pre-delay for the talent.

I agree I have heard many Marti remotes that had fantastic quality.  In my ealry days in AM three of my stations actually played records and carts from the back of a van or a portable console back to the studios via a Marti and the quality was more than acceptable.  If it was worse than a 5 kHz. phone line I would allow them to use the Marti's.

It will be interesting as more RF digital bi-directional interconnects become available to be used in the existing RPU bands and other bands in the future.

We had DBX Type 2 encoding on all marti shots.  That, along with the
occasional 100W shot really helped.  Trucks had dual 10 db antennas, studio
had 13 db antennas, and tower sites had 15' omni poles (dunno actual gain).
No show was put on the air with less than '100%', about 100 mV.  In a couple
of instances, we wound up two hopping (eight freqs helped) or running the
signal through an EQ to make it sound better (not much you can do about the
hiss)

 Shake hands. I say Hogwash. Program your station correctly with good

 Steve,  there is validity to getting out there, rubbing elbows with the

 and hanging banners. You would be hard pressed to convince me that these
thing
s don't help with the image of the station.   Have the studio announcer push
th
e fact that the remote crew is at site "A" and why you should go there. Then
gi
ve the "remote" announcer a PA mic. Don't crap up your air signal with some
noi
