Golden Age Project EQ-81

Vintage style 4-band equalizer with inductor based mid frequency bands that uses the class-AB circuit which is similar to the EQ section in the classical 1081 module, only without the high and low pass filters. Its sound character is warm, punchy, sweet and musical. The equalizer has stepped frequency controls that offers a wide selection of frequencies from 33 Hz to 15 kHz. The low and high frequency bands are switchable between shelving and bell and the mid frequency bands are 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 equalizer is not intended to be used as a standalone EQ and designed to be used together with one of the Golden Age Project models. It can also be used with many other units that have a low level (about -18 dBu to -10 dBu) unbalanced insert connector. Other features include tantalum capacitor in the signal path, TRS jack for in- and output connection and selectable ground lift switch. The equalizer uses external power supply to avoid interaction with the audio circuitry. A 230V power adaptor is included.
