Switching supplies CAN be noisy, but they're not necessarily noisy. The main thing to be careful about is putting them actually inside a box with audio stuff, but, at least as far as I've dealt with them, the external in-line ones can be kept far enough away from anything important to not cause big ...

No. Once again, you're misunderstanding us. The Tweak 003 adds another 15dbV to the headroom of the existing stock 003 design (I see that the website says 12; that's a typo, our mistake. It should say 15dB). Again, that's dBV referenced to 1 volt based upon the differences in output swing potential...

Does the reel you have have screws holding the flanges to the hub? You could take one of them off, use it to make a 7" pattern in cardstock, screw the cardstock flange onto the hub, flip it over and do the same thing to the other side.

Your recorder lays down a signal at pretty much constant amplitude, so you don't need to worry about getting tape with low noise and high saturation point. Dynamic range is totally set by the modulation depth which is in the circuit not the tape. So you can just find whatever you can find and see h...

Let me clarify: Assume that a stock 002 can swing within a volt of each rail. That gives us about 21-22 volts of output swing capability. If we increase that swing capability to 28 volts, that's a 6 volt difference in capability. 6 volts using a 1 volt reference is 15 dB. Even Digidesign uses this ...

According to your logic, since the stock 003 added 15dB and the 003 mod only adds 12 dB, that means the modded 003 actually puts out 3dB LESS than the unmodded version!!! In case you don't see where my numbers come from, 12 is 3dB less than 15, and they're BOTH referenced to 1 volt, right? OF COURSE...

I'm not sure where you're getting 5.6 times. Decibels are logarithmic. You can't simply multiply by a given number to get the answer. Since you're such an expert, Ned, here's a test of your knowledge: 6 volts= ? dBV 12 volts = ? dBV Hi. The number 5.6 comes BLA's 15dB claim and from the definition ...

Well....to give the benefit of the doubt, MAYBE they mean dBm. I think the 5532 is only spec'ed to drive 2K, so if they do a chip swap on the outputs with something that can drive 600 then they would only need to, like, almost triple the voltage to get the numbers they're talking about, so it's more...

I don't know anything about Black Lion, but I was just directed to this through someone with a question on another forum: http://www.blacklionaudio.com/digi003_mod.html Now, if you read this, you'll see a couple of claims about headroom. First, they say the stock 003 has 15dB (?!?!) more headroom th...

Hi. I'm replying to this kind of late, and I don't know if what I have to say will be of any value, but... I'm pretty sure you can use a +/-24 volt supply. You don't need to find one that will do 25 volts. That might make your life easier. The reason I say this is that every ward beck module I've ev...

If your Bronco is solid state, you should be able to unplug the speaker and play all day with no harm to the amp. You could even try just plugging the bronco right into the AC15 without adding any resistors. Just use the master volume to get it to the right level.

As far as my other post up there goes, I know it's true not only cause it's obviously true, but also cause I've done it myself several times. It's not the absolute best way to get 48 volt phantom, but it works fine, especially if you don't have a large or complicated ground system in the box, which,...

If the preamp is fully transformer balanced, both in and out, potentially you could lift the preamp's ground connection to the chassis and then connect the -24 from your power supply to chassis and +24 to phantom. You have to be careful doing this, though, as the PS 0 volt and preamp ground are now ...

You don't necessarily need transformers. You can probably wire them balanced if you open the mic and find where the wires meet the capsules. I'm sure each capsule probably has its own hot and cold wire, and the colds probably just connect together somewhere downstream. You should be able to take the...
