Re: Old analog Gear, need manuals, etc.

...and the fun fact that I get to make my own cable for the keyboard because it's a DB15 to DB9 situation of all things. Do you have the pinouts for the cable? It's not wired completely pin-for-pin. From the technical guide: Main Chassis DB15 Pin 1: +24V supply to keyboard. Connects to keyboard DB9...

Re: Old analog Gear, need manuals, etc.

Could you provide a photo of the one on your machine? It sounds like the sort of thing I could make with some sheet acrylic and a laser cutter. Sorry... we haven't had these machines since we converted our plant from analog to digital nearly ten years ago. But yes, you should be able to make it pre...

Re: Sony BVH-2180-PS: Servo Error on VHS 2000

...the machine still stops after 15 seconds of Play or Shuttle or VAR.... The Servo lamp goes on as soon as I press "Standby" and the drum starts to rotate. After 15 seconds the red System lamp goes on and the machine stops. On RL-12 board a D6 error is indicated by a LED. On the RL-12 board, D6 te...

Re: Offered with apologies to Dean Martin...

Chuck Hintz (an instructor at Sony's facility back in the early 80s) had a variant on that song that he delivered when talking about why type-C tape machines ran within a particular range of carrier frequencies (to avoid color subcarrier and its harmonics, and the resulting interference). I wonder w...

Re: Old analog Gear, need manuals, etc.

Another note: I don't know if you've used an A-51 before, but there's one really non-obvious thing that catches just about everyone: the control panel won't let you do anything until you take control of one or more channels. (You would think that a system with only one channel would automatically sk...

Am I missing something? Don't be embarassed -- it isn't at all obvious. If you're lucky, you should find ...

Sony BVH-2000 Tape Motion Timeout Errors

I just received a PM from a gentleman in Germany, who posed this question: I have a BVH 2000 PAL and have a Servo Problem. The machine displays always the red "Servo" lamp on the left. When I insert a tape and press "StandBy" i can play or shuttle the tape for about 15 seconds, then the machine stop...

Re: Old analog Gear, need manuals, etc.

...In a sales video for the A51 I saw it could be used with a monitor display to show information about the state of the machine. Is that just a straight BNC connection from the Status output on the back to a monitor? (The unit hasn't arrived yet so I can't try that myself, but if I need an additio...

Re: EAS over Barix

We have been using Barix Annuncicom 100s for better than ten years to link our spoke stations' Sage ENDECs to our centralcasting hub; they have been exceptionally reliable. Our approach is somewhat different from what I'm seeing in the other comments: the ENDECs remain at the spoke stations where th...

Re: Quiet UPS

I too have had the bulging battery syndrome with APC UPSes. I needed to take the top cover off and use a pry bar on an SU2200 that had 8 batteries inside it. My problem with APC is that their charging circuitry actually causes the batteries to overheat and swell; that's just bad design. I have neve...

Re: Quiet UPS

I haven't ever found an online UPS that was quiet and all the line interactive units that I have purchased seem to just fail. I have one at the moment that looks fine but whenever the power goes out it doesn't work even with a new battery. No alarms or warning either. So, I wanted to see if anyone ...

Re: 5.1 to 2.0 downmix card?

Anyone know of a not-too-horribly-expensive device to do a downmix from 5.1 to stereo, preferably in the SDI embedded domain? Our network receivers are sources on our router. Nearly all our *destinations* are 2.0 stereo. When we route a network receiver to any of these destinations... we don't get ...

Re: Harris Ranger Transmitter

Does it operate normally otherwise -- in particular, do the front panel functions work? It's been a few years since we shut down several Rangers (they were the temporary transmitters before several of our stations did a flash-cut), but if I remember correctly, they used the same CAN bus scheme as ou...

Re: Odd Ball or Cisco BNC Connector

Might it be a mini-BNC connector, perhaps? Amphenol was pushing them pretty hard for the telecom industry. Digikey sells them... Jeff P.S.: I just re-read your original post and saw that you had eliminated mini-BNC... but the side difference is not nearly as much as between BNC and HDBNC. P.P.S: Thi...

Just tell them it wasn't your tower that was killing them, it was the FM tower doing it. :mrgreen:
If you're talking about the tower I'm thinking of, that many bird strikes would probably collapse the thing. :lol:
