The class-AB circuit used in the EQ-81 is similar to the eq section in the classical 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 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 frequency 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 is not intended to be used as a standalone EQ. It is designed to be used together with one of the Golden Age Project models that has an insert jack. It can also be used with some other product that has a low level (about -18 dBu to -10 dBu) unbalanced insert connector. Combining one of our PRE-73 units and an EQ-81 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!
