8173

The best 80 Series sculpting tool.

Leverage your 80 Series´s investment with the Heritage Audio 8173.
The 8173 module is a Heritage Audio unique design, which has been engineered to fill input module slots in the restoration process of vintage 80 Series sound mixing consoles.

It is also compatible with the Heritage Audio FRAME 8 and RACK 2 powered enclosures, and with any other rack, console or enclosure that follows the same mechanical and electrical protocol.

Don’t settle with the same old song, the 8173 offers what the vintage modules do plus more.                                                     

The 8173 is a 73-sized module, adding the 81 mid bands to the 73 classic design, creating an equalizer that is really hard to beat. It features a Baxandall type high shelf band, but with the addition of a high frequency selector switch offering 3 different frequencies instead of the fixed one at 12 kHz. The result is a 4-band tone monster that combines the best features of the vintage modules in an incredibly smart and tasteful way, at a price lower than most current offerings.

Vintage connoisseurs and plug-in users already know how cool the 81 mid bands are for sculpting sounds in a musical way. This level of flexibility has never been present in a 73 style module.
