- Do not use unbalanced mics with 48v switched on as they may be damaged by the phantom power voltage balanced dynamic mics and leads can normally be used with 48v switched on contact your microphone manufacturer for guidance 23
- Mics should always be plugged in and all output faders set to minimum before switching 48v on to avoid damage to external equipment 23
- Mono input channel 23
- Only connect condenser microphones with the 48v powering off switch up and only turn the 48v powering on or off with all output faders down to prevent damage to the mixer or external devices 23
- Take care when using unbalanced sources which may be damaged by the phantom power voltage on pins 2 3 of the xlr connector 23

- Caution pressing this switch cuts off the normal mix l r signal and it should therefore not be used during live performance or recording 29
