Phantom Power

PHANTOM POWER INSTRUCTIONS

Connecting a phantom power pack to a lectern is straightforward once you know the signal path.  You’re essentially placing the phantom power unit between your microphone and whatever device you’re sending audio to (like a PA system or amplifier).

Here’s how to do it properly:

1. Identify your components

• Gooseneck microphone (usually condenser if it needs phantom power)
• Phantom power pack (typically 12V, 24V or 48V)
• XLR cables
• Audio output (mixer, amplifier, or powered speaker)

2. Connect the microphone to the phantom power pack

• Plug the XLR cable from your lectern microphone into the INPUT of the phantom power pack
• This is often labelled MIC In.

3. Connect the phantom power pack to your sound system

• Use another XLR cable from the OUTPUT of the phantom power pack
• Run this into your PA system, mixer or amplifier

4. Power up in the right order

• Make sure everything is turned down or off
• Turn on the phantom power pack
• Then bring up your mixer/amp volume gradually

5. Mounting considerations for a lectern

• Mount underneath the lectern using either the equipment shelf or small tray
• Secure with velcro or brackets for a clean install

Important Tips

• Only use phantom power if your mic requires it (most condenser gooseneck mics do)
• Don’t plug/unplug the mic while phantom power is on (can cause loud pops)
