A 4-band EQ unit based on the eq section in the classical 1081
NOW WITH BALANCED CONNECTIONS FOR SELF CONTAINED OPERATION!
A 230V power adaptor is included
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 MKIII 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 MKIII 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 MKIII 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!
