Heritage Audio 6673 80 Series Microphone Preamp/EQ Standard

The Heritage Audio 6673 module has been engineered to fill input module slots in the restoration process of vintage 80 Series sound mixing consoles, and is also compatible with the Heritage Audio Frame 8 and Rack 2 powered enclosures. The 6673 is a 4-band equalizer in a 73-sized module, combining the mid-band of the vintage 1066 module and an expanded 73 mid-band. This allows a more complex equalizing while also maintaining the same sonic qualities. Additionally the 6673 features three frequency options for the high shelf, as opposed to the fixed ones on both the 73 and 1066. Special care has been taken in sourcing the correct components that ensure performance will be as close to a 1070s unit as possible. Custom polystyrene and film tone capacitors have been developed to closely match the Siemens Styroflex and Mullard Mustard types of the late ’60s and early ’70s. The Heritage Audio 6673 is entirely handmade in Spain, employing the same old-fashioned wiring and soldering techniques of the ’70s.
