The complete classic 73 recording channel – preamp and EQ – in one 1U rack unit. The Heritage Audio HA73EQ Elite is a mic preamp and equaliser built to the same specifications as Heritage Audio’s 73 JR II, 73 EQ JR and DMA 73. Modern production methods are used, while the parts that make the sound – Carnhill transformers and correct inductors – stay.
Why customers choose it
Who it is for

- Only need the preamp? See the HA73 Elite.
- Higher gain positions raise the input impedance – good for low-output ribbon mics.
