So much for trying to help people out with what I thought were thoughtful posts.  Minus eight tickets in one day???  Administrators--HELP.  Who's out to get me anyway?  Be a man and tell me what your gripe is.

Same thing here. Minus 8 or 9 tickets in less than 48 hours. This is amazing and a real mistery to me ???. I've never been rude, unpolite or anything bad. I'm just trying to learn and help when I could, despite my lack of knowledge. ;)

Sorry to hear you had the same experience.

Well, from one minute to another, I have 4 tickets! Thanks everyone ;D

Here is the noise spectrum graphs of the two models operating at identical MIC input gains, and comparison of LINE input noise using low noise external preamp for same MIC gain.

Comparing the noise performances of these different models over frequency is possible with eyeing the dB scale numbers at the right to the graph lines showing the recorded deck noise levels. 





How audible, or interfering to the audio signal purity a deck's internal noise is going to be depends on the frequency, the character of the noise (like is it continuous Gaussian type or more audible digital impulse with harmonics) and the dB level (loudness-amplitude) of the noise.

It does seem, at least from see the graphs, the D50 has the quieter analog inputs.

I have no experience with the M620 but my PCM-D50 has made some of my best stealth recordings in the 5 years that I have been recording. Of course, I was using Sony and Sharp MDs and Hi-MDs before but the mic input and line input seem very quiet and dependable to me.  Just my .02 of course...

How would you compare using the mic preamps in the PCM-D50 to using your Beachtek?

I do find the Beachtek to be very quiet as well.  I pick up just a little more mic self-noise when using my micro omnis (Sound Pro BMC-12's) into the PCM-D50 than when using the Avantone Busmans into the Beachtek which is an XLR input.  But, then again, that external preamp and mic combo tends to handle the louder SPLs than the PCM-D50 preamp unless I activate the PCM-D50 attenuator which is super!

It's hard to compare since it's different mics and different situations but I won't be getting rid of my Beachtek or Avantones any time soon to just use the PCM-D50 mic input if that makes a difference in what you are asking.

Thanks.

It sounds as if the PCM-D50 is holding its own anyway, which is heartening.

I was wondering if I should hunt down a battery operated preamp to use with my PCM-D50, and was curious as to how much of a difference it would make.

Unfortunately, Beachtek doesn't make that model anymore. Are there other similar options?

Thanks a lot for the Bill Frisell recording. Sounds great. ;D

What type mics do you have now?  The attentuator on that PCM-D50 does a super job and the digital limiter has it's merits too. If you have a miniplug type mics now, don't waste your time looking for a battery box, just use the PCM-D50 until you find it's not doing the job...

I have an old stereo condenser SONY ECM-979 which has XLR connectors but doesn't put out much signal. I just bought an AT822 (being shipped) which has a mini-plug end so maybe that'll be good enough.

I take it you're happy with the Beachtek preamp. Is there any other one that's as good?

You can run that AT822 into the mic input for acoustic shows and go line input for loud rock and be good to go...

I modified that Beachtek to accept a lithium ion DVD type battery with the help of the company.  It was a whole lot cheaper than what Sony wants for an XLR to miniplug preamp to go with the PCM-D50.  You should be able to find some DXA-10s around the internet if you search or even contact Beacktek directly and tell them what you want,etc.

I made some really decent shows with the AT822 when I first started.  It's a great mic that's easy to setup and run.   It should serve you well with the PCM-D50.

Hey Guy, thanks for the continued analysis of this gear.

Do you happen to have specs on the voltage/dB level of the Sony D50 inputs (mic lo, mic hi, line)?

Please DO NOT mail me with tech questions.  I will try to answer in the forums when I get a chance.  Thanks.

Did that give you significantly longer battery life when using phantom power?

BTW, thanks for your replies, and I'd give you a +T if I knew how!
