A classic is revived, with some modern twists to fit your needs for tone and function!

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.

The HA-609A is a modern take on the classic transformer coupled diode bridge compressor/limiter design, with several improvements brought in to accommodate the modern workflow. While some classic iterations of this design utilized some IC chips and a class A/B amplifier stage, the HA-609A features an entirely discrete, class A design and a total of three Carnhill/St Ives transformers per channel. The addition of a fast attack mode for both the compressor and limiter section allow the HA-609A the flexibility to handle individual tracks as well as groups and 2-bus program material. Thanks to a proprietary system of diode bridge gain reduction cells introduced with the highly regarded SUCCESSOR, the HA-609A has better channel matching than any earlier incarnations; while the use of rotary switches and high quality, stepped pots allow for easy recall and maintain a perfect stereo image.
