Classic Neve 1073 recreation preamp / DI, stereo in a single rack space with external power supply included.

Heritage Audio DMA73 Features

  • 80dB Class A Microphone preamplifier, HI-LO selectable minimum input impedance, balanced and floating. High gain positions show a higher impedance, ideal for old ribbon mics.
  • 50Db Class A Line preamplifier, bridging input impedance, balanced and floating.
  • All discrete Class A Ultra High Impedance J-Fet Direct Input on a high quality Neutrik Jack. The DI circuit is ahead of the Mic Input transformer, so the transformer is on when in DI mode.
  • Class A single ended, 2N3055 driven, high headroom output stage.
  • Individual Neutrik gold plated XLR connectors for microphone and line inputs.
  • Gold Plated Neutrik XLR output.
  • PAD: 20dB Mic input attenuation ahead of the input transformer to avoid overloading it.
  • HI PASS FILTER: Active all discrete Class A 3rd order Bessel, 80Hz Hi Pass Filter. 18dB/octave slope.
  • OUTPUT control to allow overloading of the preamp.
  • External linear PSU to avoid electromagnetic radiation into the audio transformers ( a.k.a. hum ).
  • Carnhill Input and Output transformers.
  • 3 gain stage, genuine B283 gain card modular construction.
  • Marconi style knobs and vintage style engraved pushbuttons.

Heritage Audio DMA73 Specifications

  • Microphone input impedance: HI, 1200 Ohm minimum, LO, 300 Ohm minimum. Higher gain positions gradually have greater impedances, optimum for lo gain ribbon mics. Input is Carnhill transformer balanced and floating.
  • Line input impedance: 10K Ohms bridging, Carnhill transformer balanced and floating.
  • DI input impedance: Greater than 2 Megohms, unbalanced.
  • Output impedance: Less than 75 Ohms, Carnhill transformer balanced and floating, to drive a load of 600 ohms (factory terminated).
  • Maximum output: Greater than +26dBm into 600 ohms.
  • THD: Less than 0.025% at 1 Khz, less than 0.05% at 100Hz.
  • Frequency response: 20Hz ( +0.3dB ) to 20Khz (-0.2dB)
  • Maximum gain: Slightly greater than 80dB
