Strengthen your sound with British Holy Grail compression

Based on legendary vintage British-spec diode bridge compressor/limiter designs, the Heritage Audio HA-609A powers your mixes, stems, and tracks with punch, weight, and color. This boutique 2-channel unit features a fully discrete Class A signal path with three Carnhill/St. Ives transformers per channel, plus a transformer-coupled '73 style gain circuit for compressor compounding gain. For maximum sonic and operational flexibility, the HA-609A is equipped with special quick settings for compression and limiting, along with stereo link and dual mono modes.

Add warmth, girth and authority to any sound source

Like all equipment in the Heritage Audio Elite series, the HA-609A is handcrafted at Heritage's headquarters in Spain, using state-of-the-art manufacturing methods and state-of-the-art components, including rotary switches and precision, stepped potentiometers for precise retrieval and matching. channel. The Heritage Audio HA-609A is ready to add warmth, girth, and authority to any sound source and delivers some of the sweetest, vintage-flavored compressions we've heard in this price range.

Perfect for tracking, mixing and mastering

Fast, standard attack times make the HA-609A an ideal dynamics processor for recording individual tracks as well as during mixing and mastering. The HA-609A's proprietary diode bridge design allows precise channel-to-channel matching of compression and response curves to hundredths of a dB. Extended threshold range for compressor and limiter, as well as true bypass for both channels (plus bypass on individual compressor and limiter functions) increase flexibility to accommodate contemporary hybrid workflows.

Strong, fast and vigorous compression

The HA-609A's compressor section offers controls for threshold, ratio, release, and bypass. In addition to the standard fixed attack time (tailored for general program material), the compressor also offers a special fast attack mode designed to capture loud transients on drum tracks and other challenging, highly dynamic material. The compressor's compounding gain is a Class A amplifier with transformer-coupled output, inspired by Heritage Audio's acclaimed '73 preamp.

Modern Throttling for Contemporary Workflows

With an extended threshold range and a new “quick attack” setting, the HA-609A offers classic limiting with the modern workflow in mind. The HA-609A limiter is extremely versatile, adept at everything from subtle peak control to the most extreme sculpting, while controlling fast percussion transients and general program material. The limiter section has controls for limit level and release time and can be bypassed. Considering the HA-609A's impressive sonic performance and versatility, it's incredible that Heritage Audio was able to bring it to such an affordable price point. But then, that's what they do.
