A great 80 Series tool for the ultimate control
Leverage your 80 Series´s investment with the Heritage Audio 6673.!
The 6673 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.
The 6673 offers what the vintage modules do plus much, much more
The 6673 has a Class A Mic preamp with 80 dB of gain to make sure you´re never lacking for more."This gives you
more than enough even for demanding ribbon mics and older dynamic mics, which are often low output."With the 6673
your mic collection has never sounded better."
There is also a Class A line-level amplifier with 10 dB of additional gain as well as -20 dB for when you need to reduce a
very high signal coming into the unit before EQing it."Both the Mic preamp and the Line amplifier have their own
separate exclusive Carnhill transformers to guarantee solid, professional results."

The 6673 is a 73-sized module, adding the 1066 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. There are also two Mid peak bands (Hi & Low) with
10 selectable frequencies to choose from each in addition to the OFF position that removes the filter from the signal
path."Then you have a Low Shelf band, also of the Baxandall type, with 4 selectable frequencies available for some
incredible low end shaping."The result is a 4-band tone monster that combines the best features of the vintage modules
in a smart and tasteful way, at a price lower than most current offerings."And not to be overlooked, the 6673 has a
Class A High Pass Filter with 3 frequencies to choose from to make you can clean up the very low end allowing more
room to achieve the sound you want."
Vintage connoisseurs and plug-in users already know how cool the 1066 mid bands are for sculpting sounds in a
musical way. This level of flexibility has never been present in a 73 style module and will certainly make finding that
elusive sound much easier.
Using the right components is necessary to achieve
desired sound
Special care has been taken in sourcing the correct components that
not only ensure that performance will be as close to a 1970´s unit as
possible, but also gives your top-class studio the look and feel it
deserves to help enhance the overall experience.
Custom polystyrene and film capacitors have been developed to
closely match the Siemens styroflex and Mullard Mustard types of the
late 60s and early 70s."This attention to detail is reflected in the unit´s
performance and is appreciated by the end user.
Carnhill input transformers are hand wound at its Oxford factory
exclusively for Heritage Audio, enclosed in vintage correct green metal
cases for the ultimate in detail nailing. The vintage character is indeed
guaranteed and you won´t find them in any other brand´s products.
A solid, thick output is guaranteed with the use of another Carnhill
transformer on the fully balanced output. The RACK 2 and FRAME 8
contain output pots to control the exact level required.
The Heritage Audio 6673 is entirely
handmade and hand wired by our most
experienced technicians in our facilities in
Madrid, Spain, employing the same wiring
and soldering techniques of the 70s. All its
circuitry is conveniently held on 5 plug-in
cards.
