Heritage Audio 609A

Heritage Audio is proud to announce the HA-609A, a modern, improved take on the classic tracking/mixing diode bridge compressor. As with the other products in their Elite Series, the HA-609A takes advantage of the latest in manufacturing technology to offer an unprecedented value without compromising audio quality — all built at the Heritage factory in Spain.
