The Cloudlifter CL-4 Mic Activator from Cloud Microphones is a single rack-space, four-input solution for common audio problems involving low-output passive microphones, including ribbon mics.Based on Cloud’s award-winning Cloudlifter technology that converts phantom power into an additional +25 dB of ultra-clean gain Cloudlifters can be used to drive stronger, cleaner signals over long XLR cable runs, or to eleminate having to crank a noisy preamp up to eleven.
 
Housed in a rugged steel enclosure providing shielding and durability the CL-4 features four rear-mounted sets of balanced XLR inputs and outputs and is ideal for broadcast, live sound, public address, and professional studio applications.
