Vendo rarissimi e bellissimi Equalizzatori Vintage Fairchild 664 montati a rack con transformatori LUNDAHL e JENSEN, di seguito descrizione e specifiche fantastici anche per il mastering

The MODEL 664 Equalizer is designed around the thin line dimensions of the
FAIRCHILD INTEGRA/series, 1-1/211 wide by 5-1/411 high by 5-1/2" deep. It has
five high frequency accent positions: 4KC, 6KC, 8KC, 1 0KC and l 5KC. Equalization
is accomplished in five steps for each of these selected frequencies, culminating
in a total equalization of 10 db. The high frequency response curve takes a haystack
shape, which allows maximum effect with minimal equalization. This type of
response curve minimizes trouble with excessive equalization of later stages of
tape, disk or film transfer. High frequency roll-off is also available on the 664
at the rate of 6 db per octave, and the curves indicate the roll-off possible. The
664 contains a low frequency boost position, five steps, with a maximum of 10 db
- boost, and a complementary roll-off of lows is available as indicated in the curves.
If desired, the high frequency response of the 664 equalizer can be modified by the
·user, and instructions for modification are provided with the unit. The unit can be
modified to provide 2, 3, 4, 5 and 7. 5KC equalization points if so desired rather
than 4, 6, 8, 10 and 15KG. All or only one of these equalization points can be
obtained as desired by the user.
The Model 664 is a passive device with an insertion lass of 17 db. Its size permits
mounting in a rack or right on the console. It can be used with conventional low
impedance professional equipment and will accommodate input impedances up to
600 Ohms, and has an output impedance of 600 Ohms.
