Marantz Rack Mount CompactFlash Digital Recorder Good for many things... but one very limiting flaw.


TOP of the line Marantz rackmount LAN capable recorder, denon-marantz pro (d-mpro dot com) makes several rackmount digital recorders. The PMD series are more Marantz - the 560 entry level, 570 with extra switching, and this one the 580 with LAN connectivity and a lan server inside, plus a cpu to "do" stuff on its own without people, i.e. setup play schedules, record schedules, use a 1/4 jack to do one of 3 programmable functions, etc. Now on the Denon side there is the 600 series rackmount - they mimic the dmpro 661 to a large degree, use sdhc cards instead of CF cards (no big deal) and have nice OLED displays instead of the backlit LCD display on the Marantz 5xx series. So why did we buy the 580? Well - ITS THE ONLY ONE THAT YOU CAN PLUG INTO YOUR NETWORK! - and eliminating a person to remove the memory card really is a big deal in cost of operation over years of use.

We bought the PMD580 for one main reason and one backup reason.
Good for many things... but one very limiting flaw., This product delivers on most of its promises, has decent sound, seems simple and reliable to operate. But there is one problem that prevents me from using it as I had intended to... and this may be the case for many potential purchasers.

The Web GUI is nice, and as long as you have a browser window on one computer open continuously during operation, it works fine. But once the PMD starts recording, you can only stop it from the same window in which you started recording. If you navigate away, and then return to the PMD, it shows a login screen, but when you attempt to log in it says "Please stop recorder before logging in". If you want to be able to start and stop recordings over the web - say, via your cel phone or laptop - this is a big problem. You can start ONE recording, then access the machine again only when the card fills and recording stops.
If you have, say, a 32GB CF card in there, that means that if you initiate recording remotely, it'll be at least 32 hours (weeks if recording MP3) before the card fills, recording stops, and you can access the machine remotely again.

You can physically hit the stop button on the machine... but that defies the point of remote access.
Great, reliable, and simple to use!, I purchased this recorder last year for a church sanctuary. It was easy to set up and once settings are in place, recording is as easy as pushing one button. The network features are great, especially the web interface controls, which are so much easier than trying to adjust settings only viewing the little screen on the recorder. With a wireless network, I can control the recorder from a laptop anywhere in the church.
nice product, this digital audio recorder is a good piece of equipment. it was purchased for our auditorium control room. it has worked well with all of our high-end digital equipment. i haven't used it a lot, but when i have, it has worked well and is easy to use. highly recommended.
