Heritage Audio 1073, 8173 & Rack 2

This bundle comprises a Heritage Audio 1073 and Heritage Audio 8173 Mic preamps and EQ modules and a Heritage Audio Rack 2 PSU


The Heritage Audio 1073 is a faithful recreation of the fabled AMS Neve 1073.



  • 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.

  • 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



When launched in 1972, the 1081 became the most flexible equalizer ever in a mixing console. Its 4 band equalizer allowed sculpting the sound in such a unique way, mainly due to the fact that both mid bands covered almost the whole audio spectrum in 20 steps. Unfortunately, a class A/B output stage was used instead of the class A one used in the 1073, making it a second choice for tracking in favour of the 1073.


Being users of the old modules for 20 years, we always came with the "could it be possible to have a 1081 eq with a 1073 preamp in our console?" question. The answer has been NO, until now...
We are proud to introduce the 8173 mic pre- 4 band equalizer module. The name says it all. The best of both worlds in an 8 3/4" module package, fully compatible with Series 80 consoles. It could be easily described as a 1073 with the mid bands of the 1081. We´ve decided to keep the 1073 Baxandall shelving lo and hi eq bands as they sound amazing, but have implemented a choice of 3 hi shelving frecuencies, a la 1084. Flexibility and Tone!!!

  • 1081 Upper Mid Frequency: +/-18dB peaking, fixed 'Q' , selectable centre frequencies of 1.5Khz, 1.8kHz, 2.2Khz, 2.7kHz, 3.3Khz, 3.9kHz, 4.7kHz, 5.6kHz , 6.8kHz and 8.2Khz , inductor based.

  • 1081 Lower Mid Frequency: +/-18dB peaking, fixed ´Q´, selectable center frequencies of 220Hz, 270Hz, 330Hz, 390Hz, 470Hz, 560Hz, 680Hz, 820Hz, 1000Hz and 1200Hz, , inductor based.

  • High Pass Filter: 18dB per octave slope, switchable between 50Hz, 80Hz & 300Hz, inductor based. (Although push button switches has been used instead of the classic rotary switch, the circuit is the same exact one found in vintage 1073s, sacrificing only one frequency choice for space issues .Real state is tight inside these modules).

  • EQ Button: Switches the equalizer on or off.

  • Phase Button: Flips phase180º.



The Heritage Audio Rack 2 is handmade in the EU employing the same exact ISEP mechanical components used in the Series 80 consoles. Aluminium rails, guides, etc. This will ensure your vintage modules, as well as any of the currently made, will fit like a glove.


Every channel has its own output control as well as illuminated phantom switch.


In addition, 2 discrete class Aultra high impedance JFET Direct Inputs have been implemented, allowing for direct plugging of hi impedance instruments.


Also, the Rack 2 is ready for linking up to 2 2264 compressors in 2 busses, A or B.
Back panel features Neutrik gold plated XLR connectors for Mic and Line inputs, as well as outputs.


External Power Supply Unit is connected via Neutrik gold plated 4-pin XLRs. It is configurable for 220-240v or 110v. Power supply is included and able to power up to 4 Rack 2.
