Heritage Audio DMA-73 Preamp

The Heritage Audio DMA-73 Preamp is a true dual 1073 style mic preamp in a 1 rack unit format. It has some added key features that will cover all the recording needs for engineers and musicians that don´t find the need to track with an EQ.

Employing only discrete circuitry and conventional components, the DMA73 is a faithful 3 stage all class A 1073 preamp. Styroflex and tantalum capacitors have been used throughout. No corners cut. A useful all discrete class A hi pass filter has been added, essential for recording everything with the exception of probably kick drum and and bass.

The Line mode allows for reamping of prerecorded tracks and it´s perfect for adding some class A color to lifeless recordings. The DI circuit is an all discrete class A JFET circuit ahead of the MIC transformer, so all the juice is there. Since its introduction in 2012, it has become a classic DI for bass.

Power handling has been addressed by means of an external linear power supply, which is included in the package.
