Product Description

Each HA-872 is entirely hand built, this includes the plating which gives each mic its own slightly unique look. Designed for studio use where the neutral balanced character of a microphone can really shine, the HA-872 has excellent off axis response, and a huge dynamic range. It captures virtually any source at a variety of distances, and the triple layer headbasket design reduces the need for pop-shields & reflection filters. It also helps to lessen the proximity effect from close sound sources. Its frequency response in “classic” mode calls back to classic FET microphones of the 70’s, with a significantly reduced high end “peak”. However, should the situation require, the “DE-emphasis” can be totally removed with a switch providing a more open sound typical of a more modern condenser. There is also a three position low cut switch, giving a bit more flexibility when recording bass heavy sources.


The microphone is comes with a custom shock-mount to keep the mic stable in any location, and a high quality 3 meter cable, all of which comes in a custom flight case with pre-cut foam inside and a 3 year warranty!



HA-872 Session Examples

Examples of the HA-872 on vocals. These include a dry ‘VOX ONLY’ version with no post processing at all, as well as a version of the mix with only reverb and delay on the main vocal, and the fully mastered track just for reference. We are working on getting more examples ready for other sound sources so stay tuned!
