Vintage Style 4-band Equalizer
EQ-81 MKII
INTRODUCTION
Congratulations on choosing the Golden Age Project EQ-81 MKII Equalizer!
The class-AB equalizer circuit used in the EQ-81 MKII is similar to the eq section in the classic 1081 module,
without the high and low pass filters.
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-81 MKII has stepped frequency controls that offers a wide selection of frequencies from 33 Hz to 15
kHz. The BASS and TREBLE frequency bands are switchable between shelving and bell and the MID frequen-
cy bands is of the bell type with a switchable Hi Q setting. The control range is +/- 18dB. All four bands can
be set in an off mode.
The EQ-81 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-81 MKII and using a UNITE rack kit
to mount them together, one will get a 19-inch 1081-style unit at a low cost and with a great sound!
