Posted: Mon Aug 08, 2011 12:57 pm Post subject: Dueling pre's or Nice Fit? |
|
|
Hey all,
*Disclaimer: Like many out here, I am not an audio engineer…not even close. I know just enough to produce pretty good audio. Please forgive my naivety.
The mic pre shootouts and like discussions have been very timely and informative for me.
I've been using a DBX286a for over a year, and have the settings just about where I need them for my uses. I read Bill Campbell's suggested "9:30" settings, and will test them out tomorrow. Apparently, these settings worked out nicely in Tom Test's trial and got some good feedback out here.
Striving to better my product, I've been considering picking up a Golden Age pre 73, thinking that it may bring a bit more 'punch' to the table…
I do like the processor on the DBX. The gate is great for dialing out any unwanted sound.
Here is the question *(please refer to the Disclaimer): Could I combine these two pre's with any successful outcome to get the best from each? |

You could but that would be defeatists. The same problem that occurred in Tom's pre shoot out would happen by this "Bi Preamp" set up- one preamp will color or augment the other. _________________ The Blog:

Thanks Mike! I'm guessing that the 'coloring or augmenting' you speak of would be an undesirable thing, right? |

|
|
I sort of have - potentially - the same dual-pre issue: Right now I'm running the mic right into my laptop using a Blue Icicle, which is ok (it was given to me free), but I have a Symetrix 528 (not *E*) I'd love to use, but I still need to have the interface for the computer, and the Icicle is it.
I was going to post a question about the possible issues of *doubling up* on pre's - Symetrix into Blue Icicle into laptop - but Mike answered it: one preamp will color or augment the other.
Can anyone suggest a good interface that isn't also a pre, and also isn't a ton of cash? _________________ ~Shock

But this is where I guess I'm not getting it. Having the GA73 contribute some color and 'augmentation' was kind of what I thought might be a good thing. I was hoping for having these two pre's compliment one another. 'Best of both, ya know?
Maybe combining pre's is often a bad idea. I sure don't know...
Ultimately, I'll take the feedback of those in the know to heart.
(I have a suspicion that someone may use the phrase "Bi-Pre curious' on this topic...) |

Not sure about the 528-non "E" version, but on the 528E I bypass the pre section, going line in from my preamp & then using the Symetrix just for downward expansion to manage BG noise along with a bit of EQ.... No "2-Pre" circuitry involved. _________________ If attacked by a mob of clowns go for the juggler.

Yes, it can be. It would be like mixing different wines in the same glass. What you have will still be wine, but the complexities of each will be lost and may not be as enjoyable as the each of the wines on there own.
Let's then look at compressors. Compressors, for all intent a purposes, are amplifiers. These amplifiers can be clean to colored. A compressors like the LA2A for example are cherished for the tone and sound that they bring to the mix. Just running a signal through the LA2A without compression will add an extra dimension to the audio.
BUT let's understand something. Compressors are designed to take line level in, and that's the diffrence.
So if you're running the audio from let's say the GAP, into the DBX 286a you may get louder but you may not get anything special. There can also be impedance problems because you are feeding line level out from one pre into what it normally mic level impedance, things can load up and distort or create other problems - like hiss or noise. Levels can get very hot and distort, again not a good thing.
Can you do it? SURE. But not me.

If you have Firewire, the Echo Audiofire2 is an excellent unit. _________________ The Blog:

Thanks again, Mike. I'll look into your suggestion for an interface. _________________ ~Shock

I know a talent who got in an interface bind and ended up running her preamp through her MicPortPro with the gain on the M all the way down so as not to add extra gain.
She did note that she had to lower the gain on the preamp a couple clicks so that's evidence I suppose that even wtih the M gain all the way down it is still adding some gain.
She asked me to listen to the audio and I thought it sounded clean with no extra buzz/fuzz/coloration and later she said her clients had no issues.
She of course later solved her interface problem but it was interesting to see that in at that one case, the mixture worked. _________________ ____________________

The M has a Class A preamp, which means that its never really "off".. its basically "idling" until you feed a signal thru it...so regardless of whether you have the gain on the M up or down, you're still running it through the pre on the M , nonetheless... |

So I guess we've come back to my original topic of pairing-up pre's... |

One day I'm going tot take a M apart and see what's really inside.
My guess two IC chips- with an Op amp for sure. Not much room for anything else. _________________ The Blog:

..if one does not have firewire, what are some good yet inexpensive AD interfaces (USB) without preamps?

Define inexpensive.
There are a lot of cheap / inexpensive USB interfaces. Then for a few hundred dollars more there are some USB interfaces that will put you in a better place - in terms of audio quality.
If you have a tower computer you can install a Firewire card for just a few dollars.
But you need to figure out: do you want to get by, or do you want to sound good? Each has it's own price. _________________ The Blog:
