If you are having trouble hearing the difference between the microphone models, we suggest running a null test as shown in the video above.
Optimal Recording Levels
The Classic Tubes microphones are calibrated so that an input signal peaking around -12 to -10dBFS will match the original mic tone most accurately.
You can use the VMR Trimmer module before the Classic Tubes module to monitor your input level as you record or adjust it later in the mix.
For special effect, you can drive the Classic Tubes Module harder to get more harmonics and tube saturation, and you can further amplify these characteristics with the intensity knob.
Please ensure that the VMS is setup correctly and that you are using the correct cabling. You may want to consult the user manual for your audio interface as well as the User Guide for the VMS system here.
