3 Zigma Audio CHI HA-FX/C-LOL-47 Large Diaphragm FET Condenser (DEMO) – Open box, fully operational, in near-perfect cosmetic and working condition, includes all documentation and original packaging, and full warranty CHI (Capsule/Head-Amp Integration) is the perfect combination of technology and tone. Finally, sound is not sacrificed for Specs. And still - the CHI System has some of the best specs in the universe! The HA-FX (Head Amp/FET/Transformer-Coupled) is designed for Live Sound Applications and High SPL Recording. HA-FX includes Transformer + PAD & HPF for Tone & Dynamic Control The CHI is designed to be an extremely flexible platform offering the demanding engineer a range of sounds going from the most classic vintage toned capsules to the most true to the source, "straight wire", modern specs capsules. Made to be reliable and robust, this microphone system must be regarded as a long term investment, and one that can only grow: indeed, as you add more capsules and accessories, your CHI system will expand and offer more options thus enhancing your recording, helping you getting the sounds you're after in the studio and generally speaking, broadening your sound "palette" when recording. The CHI head amp has ample headroom, extremely low noise and is totally stable and perfectly shielded. The main strength of the CHI system lies in its flexibility: the versatile head amp lets you pick the sound and behavior of the capsule to form a combination which offers a sound ranging from transparent and unobtrusive (using the small diaphragm capsules) and flexible (many different polar responses) to obviously colored (any of the large diaphragm capsules). Included is the C-Lol-47 (Cardioid/Lollipop shape/U47 style) capsule. Designed with the U47* in mind, this capsule will give the CHI head amp the color of the famous old German condenser which became a classic for mellow vocal recordings. More directional than a straight Cardioid, but still considered to be a Cardioid capsule. Can very "Robust" used close to the source.
