    Golden Age Premier PREQ-73 proper connection doubt

    Sign in to disable this ad
    Hi,

    I'v recently purchased the Golden Age Premier PREQ-73 (Neve 1073 clone) (Golden Age Premier PREQ-73 – Thomann Portuguesa) as my first mic/bass/agtr preamp.

    My current home studio setup consists of;

    Phonic PPC900E Power Conditoner

    Avid Digi003 Console Audio Interface

    AKG C-314 Condenser Mic

    Several Guitars and Basses along 2 electro-acoustic guitars.

    DAW is ProTools HD 12

    I connected my GAP PREQ-73 to the input 5 of my IO (since inputs 1-4 of the Digi003 have their own pres and i'm under the impression that it's not a good idea to cascade pres)) with the +4 pad activated thru a balanced XLR (Klotz and Neutrick) to 1/4 Jack.

    I recorded several VoiceOver works to test the GAP and i had to dial the input to +60 and almost 2 o'clock in the Output Gain ( the EQ section was not activated) to achieve what i consider to be the proper Gain Staging for the recording.

    To my surprise I noticed quite an amount of noise thru out the all recording (kind of noise-floor or electrical noise) altho i have the Phonic to deal with that.

    All cables are new and custom made by a local pro.

    I would most appreciate any advice or feedback regarding this issue i'm having since i might be doing something wrong.

    Thank you in advance for any help,
    Lemec

    Could you post a link to the raw track (from your project audio files, not a bounce/export), posted on Dropbox or similar?

    I have a Pre-73 and use it with a couple different condenser mics - I probably use some similar settings, though I haven't used it with my C214 lately. (The closest thing I have to your mic.) I just looked at the Pre-72, and with the Miktek C300 I have plugged in the settings are 55 and probably closer to 2:30 on output gain. Haven't noticed what I'd call noticeable noise. (I'm plugged into a Focusrite Pro 26 which has no switch for line level, but can accept up to +28dBu, so is in that +4dB range, if I understand all these different yardsticks...)

    Do you get the same kind of noise when using it as a DI?

    And the C314 has no noise when plugged into a mic channel on the Avid?

    I assume the 1/4" *plug* is TRS (balanced, as well)? I suppose there's always a problem with the cable, so it never hurts to try a different cable. You could even use a guitar cable (unbalanced) temporarily to see if that makes a difference. The level will probably drop a bit, but noise should be the relatively the same if it is not a cable problem.

    Hi Keith,

    Thank you for your interest and kind reply.

    I have not yet used the GAP PREQ-73 as a DI and yes, the 1/4 jack is TRS (balanced and new)

    Here is a link to 2 audio samples (one with the mic connected to the DIGI003 pre and another one with the mic thru the GAP-PREQ-73 thru a line input of the DIGI003) in Mp3 Mono 320 Kbps 24/48 format. Thee GAP was at 50 in the input section and 3 o'clock in the output gain (no eq engaged only teh 48v of course).

    Can you check it and tell me if that's normal ?

    Thank you again,
    Lemec

    I'm not hearing a huge difference though I can *see* a little more noise in the wave, assuming the big bumps in both files are something picked up by the mic itself. They both measure about -59dB in the first part when playing them in Logic, with a jump to -44dB at the ends.

    Did you look for the raw audio files?

    No...those were fresh recordings i just made to A/B as you suggested.

    Wasn't it suppose to have less "noise" ?

    Do you find that level of noise (-59Db) normal and acceptable under these conditions ?

    Here is an audio sample of the Mic thru the DIGI003 pre without the Phonic PPC900E Power Conditioner.

    Sorry for delay - been a little busy.

    Now, I don't know the proper way to test this, but in my home mix (and occasional recording) space, -60dB is probably the best I could hope for. In the few minutes I just spent trying to set something up, the airplanes and distant truck noise made even that a quixotic quest...

    So, short answer, I wouldn't expect the Pre-73 to really be any quieter than an interface preamp, and I wouldn't have been surprised if it had been a tiny bit noisier, TBH. After all, it's primary selling point is to provide color. I don't think they even publish a noise spec for the thing.

    I just set a SDC in front of a cheap Behritone 5" speaker with some pink noise running through it, with the pink noise measuring about 75dB on my iPhone app. Recorded a track with the Pre-73 Gain at 55 and Output as 12:00. Adjusted the line in level on the (combo jack) input of a channel on my Focusrite so it was showing -12dB in Logic Pro X for that track and recorded with the noise on, and then off. I did the same thing with the same mic but plugged directly into the Focusrite and adjusted the channel gain so the track in Logic was also -12dB. Here are the raw tracks. I did not normalize, but they are pretty much the same to my ear/eye.

    Just my 2 cents, I had the GA PRE-73, I thought it was a great unit for the price. From what I remember it had a little noise but nothing to stress over. I think the sound it delivers makes up for it. I've read nothing but good things about the unit you have. Good luck!

    It (a little hiss) should be WELL below the signal you are recording. If you are hearing something during a strong signal, then something might be wrong.

    Golden Age Premier Pre-73 & PreQ-73 |

    You will have to buy the .pdf to get the full SP but I don't think the original Neves were UBER low noise?
