Heritage Audio Releases HA-73 EQX2 Dual Mic Amp/Equalizer

Heritage Audio has released the HA-73 EQX2 Dual Microphone Pre Amplifier / Equalizer. The HA-73 is equipped with two mic pre/equalizers in the same rack unit. Employing three correct-vintage Vinkor pot core inductors, the Elite Series HA-73 EQX2 DUAL MIC AMP/EQUALIZER’s EQ curves are almost indistinguishable from the handmade equalizers in Heritage Audio’s product line so customers can expect the same sonic quality and feel that they have come to appreciate from the company.
