Is this happening?
Announcements are loud but unclear. Turning it up makes it harsher, not easier to understand. Some voices cut through, others vanish. You keep chasing volume but clarity doesn't improve.
How the problem shows up
A facility uses a paging or lectern mic in a large, noisy space. The mic signal is weak, so gain gets pushed somewhere in the chain. Once you push gain hard, noise and artifacts ride under the announcement and intelligibility suffers.
The problem
Speech needs clean level, not just more level. Extreme gain can add noise and harshness that masks consonants.
The fix
Strengthen the mic signal before the system preamp has to work overtime.
Paging/Lectern Mic → Cloudlifter → Mixer/Processor/Zone System (phantom power +48V ON) → Amps/Speakers
Note: Cloudlifters work with passive dynamic and passive ribbon microphones. They are not compatible with condenser microphones that require phantom power through the XLR cable.
Choose your Cloudlifter
If you want the simplest setup: use the CL-25 Mini. It's the quickest "one connection" way to add clean gain.
With the CL-25 Mini, it plugs into the bottom of the mic or into the preamp input, then your single XLR cable completes the connection.
If you already own a Cloudlifter: the CL-1, CL-2, and CL-4 do the same job (clean mic activation). They use the standard inline connection in your mic chain.
A quick example
A warehouse kept turning the paging louder, but clarity never improved. Adding a Cloudlifter on the paging mic line allowed lower gain in the system and cleaner speech that was easier to understand without "blasting" the room.
FAQs
Does my mixer or processor need to supply phantom power? Yes — the mixer, processor, or system input must supply +48V phantom power, and it must be turned on. The Cloudlifter draws phantom power to operate; without it, you'll get no signal. Check your system's manual to confirm phantom power is available on the mic input.
Will this fix a reverberant room? It won't change acoustics, but it can reduce noise and artifacts introduced by extreme gain.
Where does it go? Inline on the mic before the system input.
Quick takeaway
If your PA is loud but unclear, a Cloudlifter helps you get more mic and less preamp—so speech cuts through.
