Phantom power and the CM-15:

What is phantom power?

  • 48V DC power sent through audio cable
  • Powers condenser microphone capsule
  • Standard in professional audio
  • Named "phantom" because it's invisible in the signal

CM-15 power options:

USB-C powered:

  • Most common use case
  • Power comes from USB host
  • No phantom power needed
  • Works with computers, phones, tablets

Phantom power (via XLR): 1. Connect CM-15 mini-XLR output to mixer/interface 2. Enable 48V phantom power on your device 3. CM-15 powers from the phantom voltage 4. Use when XLR is your only connection

3.5mm output:

  • Still needs power source
  • Use USB-C for power while using 3.5mm out
  • Or internal battery if available

When to use phantom:

  • Professional recording setups
  • Connecting to traditional mixers
  • When USB-C isn't available
  • Redundant power source

Safety notes:

  • Never connect phantom power to ribbon mics
  • CM-15 is designed for 48V phantom
  • Phantom doesn't damage the CM-15
  • Turn phantom off before connecting/disconnecting

Troubleshooting:

  • No sound? Check phantom power is enabled
