Mic Preamp Application
Use this configuration for recording vocals or an acoustic instrument using a microphone. It is also applicable for live sound use
when connecting a mic or direct instrument signal using a D.I. box located on-stage.
Application Notes:
• The INSTRUMENT INPUT must be disabled on the front panel using the button located next to the jack.
• Engage the
+48V
button if connecting a condenser microphone or active D.I. box which requires it. Disengage the
+48V
button for any microphones which don’t require phantom power, such as dynamic and ribbon microphones.
• Either the PREAMP output, COMPRESSOR / LIMITER output, or both outputs can be used in this application. Use the
COMPRESSOR / LIMITER output if you wish to process the signal with the 676’s built-in compressor and/or limiter.
When using the compressor/limiter, use both jacks to have a backup of the uncompressed signal, for parallel compression
applications, or for recording the uncompressed version and sending the compressed version to the musician’s headphone
mix.
• A signal processor can be inserted in the PREAMP INSERT. Here you can connect a favorite compressor, EQ, or any other
signal processor you wish to insert after the preamp.
