4. Installation

> Please install the last release of Nebula Plugin <

For PC Users:Use the included installer to select your \nebulatemprepository folder to install the collection there. Or, you can simply copy all "n2p" files to your Nebula "Programs" folder and copy all "n2v" files to your "Vectors" folder.

For Mac Users:Copy all "n2p" files to your Nebula "Programs" folder and copy all "n2v" files to your "Vectors" folder.

With the Nebula browser you'll find the "MTP" folder with the programs. With double click you cannavigate into the "MIC" (Microphone Preamp Input), "LINE" (Line Preamp Input) and "FLT" (High Pass Filter) subfolders.

- In the Nebula’s MAST page it’s better to set the RATE CNV at 3200ms or more to load correctly the library.

5. About the original hardware

It is a real class A Hi-voltage (300v) tube preamplifier hand made in USA. Warm, smooth and clean, it sounds like no other with his three tubes per channel, dual input/output Cinemag transformers and military-grade controls. Three HPF settings (40hz, 80hz, 120hz) @12dB/oct., -100dB S/N and 130dB of headroom. Very good on every audio source, it gives open and deep sound with smooth highs during tracking, mixing and mastering session.

6. The sampling process

Carefully sampled with all natural imperfection and nuance by myself - I'm over 15 years experienced in electronics and audio engineering - in professional recording studio with high quality audio and digital cables, master grade top notch converters with audio levels perfectly matched and calibrated at 96kHz sample rate. Precisely programmed without normalizing or other destructive digital processing.

7. The programs

The programs have the same harmonic and dynamic contents as the original hardware. Line input is very clean and linear, while the microphone input is more colored and warm, due to different input impedance and circuitry. All programs are 10 kernels with high dynamic, the HPFilter is 1 kernel since it is only the filter circuit sampled alone.

8. Audio characteristics

His pure signal path with custom Cinemag input and output transformers, six tubes and class A design gives a very clean, holographic and euphonic sound. Changing the tubes in the 1st stage, allows different colors and dynamic response converting this modern clean unit into a more vintage sound but retaining details and transients, suitable for tracking, mixing and mastering use.

In the following diagrams you can see the differences between the microphone input and line input, and from the various tubes. This can help you to choose the right one for your music.

10. Using the Preamplifier:

The programs are unity gain. You can “drive” the preamp stage using the main “Input control” (1) of Nebula instead to use the "Drive fader" (2) which affects the harmonic contents in an unnatural way, but suitable if you look for an effect. Please leave untouched the ATTCK, RELS and LIQDT controls (3).

Take care with gain staging since the programs are close to the hardware, then: 0dBVU = -18dBfs.

You can use this free vintage VU meter by PSP: http://www.pspaudioware.com/plugins/tools_and_meters/psp_vintagemeter/

If your DAW is not so powerful you can render or freeze the tracks.

If you want rendering your tracks with Nebula's presets, I strong recommend the NRGUI PRO by Zabukowski from Nebula/Tools forum:http://www.acustica-audio.com/forum/index.php?f=23&t=166&rb_v=viewtopic

Thank you, all the best !
