Description
The Heritage Audio 73EQ JR is a 500-Series module with 3-band EQ and line input with the sound of the legendary 1073. The Heritage Audio 73EQ JR’s EQ is similar of the 80-Series module and they also share the same transformer coupled line preamp and Class A transformer balanced output stage. All three band EQ is of the Baxandall type with Low and Hi shelf, similar to the 1073 but features a choice of four high-shelf frequencies instead of the traditional fixed 12kHz frequency band.
The Heritage 500 Series modules are carefully engineered to match the sonic character and performance of their older 80 Series siblings. They employ the same components and headroom and distortion characteristics as their predecessors, ensuring unmatched quality.
