Overview

  • The 1Q73 is a mic preamp, EQ, D.I. and Line to Mic “impedance converter”, all in one, based on the 1970s all-time classic.
  • Designed in reverence to the original device, and infused with a plethora of functions which enhance its sonic powers, and represent the many alterations the original and modern day reproductions went through.
  • Carved out of experience and passion to bring you the sonic high end of classic sounds, for a competitive price, attractive to all, from budget studios to top-of-the-line recording facilities.

The story of one of the finest classical mic preamps of all time has been told many times, and Sonic Dune makes its mark by recreating classical sound as you have never experienced before.

Switching between PSU regulators

1Q73 is probably the first reproduction of the 1073 to use a regulator based on vintage console power supplies. Hear the clear sonic difference by switching to a modern monolithic regulator design. Switching between PSU regulators is not something you see everyday.

Switching between output transistors

Choose between the original 2N3055 and the more modern, cleaner sounding TIP41C. The subtle differences are audible in terms of the TIP41C providing a cleaner 300Hz area and a more relaxed sound, which can be quite useful in a variety of recording tasks.

Carnhill/St Ives transformers

The input and output transformers are made by the same company that made input transformers for the vintage units. Furthermore, the heart of the 1Q73 contains the famous B183 card, like the vintage original.

EQ

The low and high end shelf section of the 1073 is the ultimate sweetener, containing both amps from the original B284 card. The high shelf is fixed at 12 kHZ, and for low frequencies, you can choose between 60 Hz and 110 Hz.

ITSLoad

Some 1073 models came with an added 12k resistor on the secondary winding of the input transformer. It automatically reflects the smallest changes in the input impedance, and thus, in the sound itself. The sound is more focused, an emphasis placed on the mid-range, and with a noticeably softened high end of the sound spectrum.

Double D.I. Buffer

The D.I. input splits into two separate SE JFET buffers with a CCS bias. The output of the first buffer is forwarded to the D.I. output TRS connector, and further on into a guitar or bass guitar amp. The second buffer is used as an impedance converter for the input transformer. It allows the preamp to be used with any instrument with a pickup, synths, etc. An abundance of harmonics and life will be added to the sound of your favorite instruments. Do not expect a clean and transparent sound – just some serious mojo.

Line to Mic input

Its purpose is to allow line signals to plug directly into the mic preamp's input transformer. We added a nifty feature – a separate XLR output connector (LM output), which you can use as an independent line to the mic input “impedance converter”. If you want to send a DAW channel for color through an old tube mic preamp, you won't need two separate devices.

75 dB Gain

No cumbersome clicking between gain stages, thanks to an attenuator with an “off” position.

1200 or 300 ohm input impedance

1200 ohms is probably more desirable, but 300 ohms will increase your gain by a few more dB, and change the sound in a more aggressive manner.

Elna Silmic II and Nichicon electrolytic capacitors

The finest electrolytic capacitors increase sonic's and the low end aura of the sound.

Really liking the Eq on these new Sonic Dune 1q73s, very smooth! The input drive works really well to thicken vocals... loving them.

I found a truer, more accurate representation of all signals fed to the 1Q73. Audio was clearer, firmer and less grainy. This is a description I would normally be slightly wary of, since this could mean thin and uninteresting. However, the 1Q73 has a whole other take. The sound is very muscular and bold, whilst the texture is most definitely analogue and full bodied. Vocal mics sounded true to the mic. I plugged my jazz bass in direct with both options buttons engaged and got my best bass sound to date!
The EQ seems to offer subtle, yet well judged control in just the right regions for most signals. I managed to tame vocals sounds from many different mics and singers.
The implementation of switching of the PSU and transistor options is a wonderful method to personalize sounds further than is possible with a stock 1073...
Overall, I am utilizing this mic pre daily for everything from vocals to horns, drums to guitars. Can't wait to try them on rooms, summing and loads more. Congratulations on the successful design and build of these excellent preamps!

I've been creating my studio setup for years, and I believe that I have some very high quality gear at my disposal. My setup serves me excellent in the type of production that I do, but apparently, there is always room for surprises. I've loved the Sonic Dune 1Q73 from the moment I first used it, and it has found its purpose in my studio from day one. I believe I will be relying on it very often.

Music producer and owner of the Belgrade-based studio “EMPIRE STUDIO”.

Once again i am surprised by the talent of some friends of mine. They created something really cool! After the second test in combination with Neumann M149 Tube, in voice over recording session, I was deeply impressed. The sound was present, warm, clear - with a scent of neve dirt - and, compared to Tube-Tech MP 1A , massive.
Soon there will be more feedback after the next testings. I'm looking forward to that!
