Manufacturer's Description from Heritage

The Heritage Audio DMA-73 Dual Microphone Preamplifier is a 1RU 19" rack-compatible dual 80 dB microphone and 10 dB line recording module based on the vintage 1073 preamplifier designed by Rupert Neve. The remake is intended for recording engineers who want the classic Neve sound in a standard studio rack format, but do not need the equalizer functionality of the original 1073.

The preamplifier supports selectable HI-LO minimum balanced and floating input impedances that accommodate a range of microphone types including vintage ribbons. A +48V phantom power button is included on both channels, as well as an input level knob for adjusting to your source. You can also switch the module into line mode to re-amplify prerecorded tracks and add color to a mix. Plugging in a mono 1/4" input into the DI port on the front of the unit automatically switches the module from MIC to DI mode. A selectable discrete component Class A 3rd order 80 Hz high-pass filter with an 18 dB per octave slope has been added for recording sources without the effects of low frequency coloration. An output control knob is included to prevent overloading the preamplifier.

The unit is powered by an external linear power supply to reduce the effects of electromagnetic interference on the audio transformers. The unit features gold-plated Neutrik XLR input and output connectors. To achieve the classic feel of the original 1073, the unit is constructed with Marconi-style knobs and vintage engraved pushbuttons for the DI, low impedance, line, pad, phase, and high-pass functions.
