Topic: Line-In Quality: Sony MZ-RH1 v. Edirol R-09HR

[Dede2002]

here 2 samples: recorded italian TV-newschannel at living-room-volume
mics: SP-CMC-8 cardioids
power supply: 12V bbox
line in

MZ-RH1: max. gain 30/30 16bit 44.1kHz

R09-HR: max. gain 80/80 16bit 44.1kHz

I grabbed a bit if silence from each recording and had a look in a spectrograph, the HR seems a little quieter. And as I have seen elsewhere, more bass sensitive...a tad more room rumble has been picked up. Listening to the silences back to back, they are very similar.



Is it possible to do the same for the mic preamps? Aim for a -12 dB peak?

I´ll run the mic-preamp-test aiming -12db peaks in about 9 hours.


-R-09HR: sp-cmc-8/12V bbox/mic-in/low-sens

-RH1: sp-cmc-8/12V bbox/mic-in/low-sens

I´ll record 30 seconds speech from TV and 30 seconds silence at the same gain setting, which resulted in -12db peaks for speech.

more to come in about 9 hours....

Sounds good!

here it comes:
source for both samples: 30 seconds speech from TV and 30 seconds silence in my living room(of course both samples recorded at the same TV-volume setting and the same part of a recorded documenatary from my dvd-recorder)

sample 1: 16bit 44,1kHz
RH1: sp-cmc-8 cardioids=>12V bbox=>mic-in(low-sens setting)=>internal gain 16 of 30 for peaking at -12db
http://www.file-upload.net/download-1058160/spcmc8_RH1_mic_in-low_sens_gain_16-of-30_peak--12db.wav.html


sample 2: 16bit 44,1kHz
R-09HR: sp-cmc-8 cardioids=>12V bbox=>mic-in(low-sens setting)=>internal gain 60 of 80 for peaking at -12db
http://www.file-upload.net/download-1058166/R09HR_mic_in_low_sens_gain-60-of-80_peak--12db.WAV.html


You see I needed more gain on the R-09HR for reaching -12db on the levelmeter as it´s mic-in is less sensitive and doesn´t clip at high SPL compared to the RH1 input when fed with an unattenuated mic´s signal at high SPLs => i.e. amplified rock concert.

RH1 gain was 16 of 30=>53,3% of max. gain.
R-09HR gain was 60 of 80=>75% of max. gain

You can here the clicking of a clock(2m behind the mics) in the silent part.

waiting for digifish´ analysis  .........guess he´s still sleeping right now if he lives on the westcoast .

Great thanks.

I am on the very very far west coast, Australia the 51st state

Before we continue there is a change in the background hiss on the RH1 1/2 way through the silent part, do you know what changed?

yes it was me touching the gain-knob and changing the gain from 16 to 15.

Busted!

Here's the two compared visually...looks similar...just a note, the R09HR was 4 dB down on the MZ-RH1, so I dropped the gain on it to match the R09HR. That probably explains why some of the background sounds from the TV (triplet of lines running through the middle of the left plot for example) seem to fade out on the left a little.



If you are making the transition from an MZ-RH1 to R09HR I don't think you will be dissapointed.

THX!
Which spectrograph-software are you using?

I am using Edison...

Thank you all so much!

Seems the R-09HR doesn´t produce more noise than the RH1 using an external mic.
Good news !

Yes, my friend.
Still planning to sell your R-09HR?

We´ll see what the future brings ..you know it´s not the noise that made me angry .

And just imagine if the RH1 had an internal mic like the R-09HR ... All that motor noise!
