![]() (The back plate has nothing to do with the plate in the vacuum tube or the plate voltage in the vacuum tube. Another plate called a back plate, forms the other side of the condenser. In a condenser mic the mylar diaphragm is sputtered with metal – usually gold – to create one electrical plate. A capacitor is two metal plates separated by a space (and sometime an insulating material). Sometime a condenser mic is called a capacitor mic. Your CV-12 is a vacuum tube circuit, condenser mic. Phantom power is NOT needed, because the power supply provides the correct voltages. Phantom power can’t provide that kind of voltage, thus tube condenser mics have their own external power supplies. And the heater in that tube requires 100V to 135V. The Tube Type: 6072A in your CV-12 has a nominal plate voltage of 250V and can operate up to 330V. One thing for sure is that there are no latency issues with the Apollo which is a vast improvement on the 11R interface. However its very early days yet getting used to a completely new setup so maybe I'm being too harsh too soon concerning sound quality. I know its a minefield of how you use the mic (pointing at 12th fret and I'm using a Martin acoustic) but so far I achieved more natural sounding results through the 11R which I was using previously with the same mic. It might be the mic which I've had for some time? I've tinkered with different settings on the mic as well. Have tried improving the quality of sound by using unison plugins such as the Neve Preamp and although it improves it slightly the sound is still very thin. Just wondering would that be the power supply going through the Apollo? Will try powering the mic via the Apollo to see if that helps? I'm in the process of recording acoustic guitar via the mic into the Apollo and Studio One 3 but the sound I'm getting is very tinny. I've acquired the right cable and am consequently getting a great signal now so thanks for the advice Don. Would appreciate any help you can give me.Ĭlick to expand. ![]() If that is the case can anyone suggest the proper lead to run from my Avantone mic (7 pin connection) straight into the Apollo's mic/line connection then using the Apollo's preamp to power my mic if that is indeed the problem? ![]() It could be running the Avantone's preamp into the Apollo via XLR is blocking the signal or it could be something else? This is apparently a sign of the signal being muted but it only happens when using the Neve Preamp. Of note since I purchased the Neve Preamp and installed it's accompanying software there has been a slight loss of volume from the Apollo particularly while in headphone mode and when I use the Neve Preamp in Unison the lights surrounding the knob on the Apollo go red. I also have checked that the Dim function isn't enabled. ![]() Still no signal in console or in my DAW even though the Avantone's preamp is still switched on.Ĭue Outputs seemingly default to Mix but I've tried clicking Mono, again without success. I then tried activating the pre-amp in the Apollo using the Apollo's phantom power by selecting the preamp button, CH1 and +48v while also selecting the limiter button. Since I don't seemingly have the right lead to connect my mic directly to the mic/line inputs on the back of the Apollo I've tried running my mic into the Apollo inputs via the preamp for the Avantone preamp (as I did with the 11R) and got no signal in the console or my DAW. Interface Apollo Twin Duo Thunderbolt using latest version Studio One 3.Īs stated new to using both Apollo interface and Studio One 3 as I'm a former Pro Tools user with 11R interface.Ĭan record guitar tracks and instrument tracks fine through the Apollo but when then trying to use my mic I've hit a brick wall. Hi everyone new member so will state my setup first.
