Vintage Style Equalizer
EQ-73 MKII
INTRODUCTION
Congratulations on choosing the Golden Age Project EQ-73 MKII equalizer!
The class-A circuit used in the EQ-73 MKII is similar to the eq section in the classical 1073 module, without
the high pass filter. Additional frequencies have been added and the mid frequency band uses two inductors,
the higher value of the second one is used for the two lowest frequencies, 160 Hz and 240 Hz, to achieve an
optimal response.
The sound character is warm, punchy, sweet and musical. These classic characteristics have been heard
on countless recordings through the years and it is a versatile sound that works very well on most sound
sources and in most genres. The essence of this sound is now available at a surprisingly low cost, making it
available to nearly everyone.
The EQ-73 MKII has stepped frequency controls that offers a wide selection of frequencies from 20 Hz to 24
kHz.
The low and high frequency bands are shelving and the mid frequency band is of the bell type.
The control range is +/-15 dB for the two lower bands and +/- 18dB for the high frequency band.
There are separate bypass switches for all three bands.
The EQ-73 MKII can be used either as a standalone EQ or connected to the insert jack of one of the Golden
Age Project preamps. Combining one of our PRE-73 preamp´s and an EQ-73 MKII and using a UNITE rack kit
to mount them together, one will get a 19-inch 1073-style unit at a low cost and with a great sound!
