Dual 1073 Style Preamp in 1RU

The Heritage Audio DMA73 is a fully discrete, three-stage, Class A 1073 style dual mic preamp, offering two channels in a one-rack unit. Using only Styroflex and tantalum capacitors, the DMA73 is an excellent tool for adding Class A sound to a variety of recordings. Line mode allows for running pre-recorded tracks, and a discrete Class-A hi-pass filter will enhance nearly every recording.
Since 2012, the DI circuit, which is an all-discrete Class A JFET circuit ahead of the MIC transformer, has been known for its ability to transform bass lines and is considered a recording studio essential. The included external linear power supply offers power handling. Each of the two channels features fully separate controls, including input gain, mic input impedance, phantom power, phase flip, and a 20dB mic pad ahead of the input transformer. For engineers who don’t track with equalizer, DMA73 is a fully functional recording mic preamp.
