Heritage Audio brings you their 500 series version of their 1073 Neve reproduction module, employing the same specs and quality and feel found in the original.

With a commitment of non-compromise, Heritage created their line of vintage reproduction  components, including a fine group of 1073 modules, amazingly accurate and painstakingly manufactured with the same high standards as the originals. Now, they have fit their 1073 into a 3-space, easy-to-add, API VPR series 500 module.

The circuitry, the knobs, the PCB cards, the buttons, the transformers...all part of the high quality you expect in a Neve channel, more affordable than the original, plus the lowest price guarantee and free delivery you get from Sam Ash.

  • 70dB 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
  • 10dB Class A Line Amplifier, Bridging input impedance, balanced and floating
  • Class A, single ended, 2N3055 driven high headroom output stage
  • High Frequency: +/-16dB shelving at 12 kHz, Baxandall type
  • Low Frequency: +/-16dB with selectable frequency shelving of 35Hz, 60Hz, 110Hz & 220Hz, Baxandall type
  • Mid Frequency: +/-18dB peaking, fixed 'Q' , selectable center frequencies of 0.36kHz, 0.7kHz, 1.6kHz, 3.2kHz, 4.8kHz , and 7.2kHz , dual inductor based
  • High Pass Filter: 18dB per octave slope, switchable between 50Hz, 80Hz , 160 Hz & 300Hz, inductor based
  • EQ Button: Switches the equalizer on or off
  • Phase Button: Flips phase 180º

  • 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 transformer balanced and floating.
  • Line input impedance: 10KOhms bridging, transformer balanced and floating.
  • Output impedance: Less than 75 Ohms, transformer balanced and floating, to drive a load of 600 Ohms.
  • Maximum output: Greater than +26dBm into 600 Ohms, greater than +32dBu into 10KOhms.
  • THD: Less than 0.025% at 1Khz, Less than 0.05% at 100Hz.
  • Frequency response :20Hz (+0.3dB) to 20Khz (-0.2dB)
