Marantz has released a firmware upgrade for the PMD620 digital audio recorder that solves the biggest issue some users have had with the device. The PMD620 is compact, easy to use, and records excellent quality audio.
But using the original firmware, if you were monitoring your recordings with headphones you would notice a slight lag/echo effect. In other words, you’d first hear the audio from its source, and then a split second later you’d hear the audio come to you through your headphones. This can be disconcerting if you’re recording an interview.
The latest firmware resolves the latency issue. You can download the new firmware along with installation instructions from the official PMD620 web site.

April 11, 2008 at 2:17 amDownloaded firmware upgrade, followed directions, and installation was successful. No latency problem from the little I tried it after firmware upgrade. I assume there are other updates in this firmware, but Marantz does not easily provide a lot of what it does.
I had just bought the PMD 620 based on what I read and had not even used it yet. But then I saw all the latency issues being discussed. I was concerned I made the wrong purchase decision. I am impressed with the unit using the internal mics, but extremely impressed when I used the Rode NTG-2 in terms of clarity. I feel much better about my purchase now.
So far the poorest feature I see is the built-in speaker. Not very clear…. but it at least lets you know you recorded and what it sounds like.
Thanks for the link to the firmware upgrade!

Fact is that after upgrading (upload 3.1 firmware to SD via USB –> accept offer to execute –> wait device within 2 hours to restart, but it didn't happened –> retrieve battery and mount it again) Marantz PMD 620 is not switching on. Pls. advice what to do on this issue.
Thank you in advance!
