Preamplifier Best Practices
TheSM7dBfeaturesabuiltinactivepreamplifierwhichprovidesupto+28dBoflownoise,flat,transparentgainthatopti
mizes audio performance.
Adjust the gain level on the SM7dB before adjusting levels on your interface or mixer. This approach maximizes the signal-to-
noise ratio for a cleaner, clearer sound.
In podcast or quiet vocal applications, you are more likely to need the +28 dB setting, while louder talkers or singers may only
needthe+18dBsetting.Forinstrumentalapplications,youmayfindthatthe+18dBorthebypasssettingsreachtheidealin
put levels.
Using Variable Impedance Mic Preamplifiers
Select the highest available impedance setting on the external preamp when using the built-in preamp.
If you are using a low impedance setting to change the tonality for creative purposes, bypass the SM7dB's built-in preamp.
Keeping the SM7dB preamp engaged with a low-impedance setting will not yield the same changes in tone.
Microphone Placement
Speakdirectlyintothemic,1to6inches(2.54to15cm)awaytoblockoffaxisnoise.Forawarmerbassresponse,moveclos
er to the microphone. For less bass, move the microphone away from you.
