The Cloudlifter CL-1 Mic Activator from Cloud Microphones is a compact, single-input solution for common audio problems in the field and in the studio involving low-output passive microphones, including ribbons. The CL-1 uses any standard phantom-powered mixer or microphone input device to provide up to +25 dB of clean, transparent gain. This improves signal-to-noise ratio and improves the performance of passive microphone signals by driving stronger, cleaner signals over longer XLR cable runs, making them ideal for broadcast, live, and studio applications. The CL-1 is housed in a rugged steel enclosure which offers shielding and durability. Additionally, the CL-1 has provisions for stage or stand mounting. Gives passive mics up to +25 dB additional active output and keeps the direct audio path free-and- clear of transformers, capacitors, and resistors. The CL-1 houses discrete JFET circuitry that delivers clean gain while preserving the natural sonic characteristics of the sourceIt comes with a The HPC-A30 Closed-Back Studio Monitor Headphones from Polsen are designed for monitoring audio in studio, field, mobile, and DJ applications. They feature 50mm drivers that provide a frequency response of 18Hz to 22kHz for accurate reproduction of your audio. The ear cups on the HPC-A30 have an around-ear (circumaural), closed-back design, allowing for the increased isolation often desired while tracking or monitoring playback. Plus a 20' XLR-XLR cable.
