Behringer Partnership


Overview In June 2019 AMSynths formed a partnership with Behringer Music GroupĀ  to bring some exciting analog synthesizers to life. The partnership enables our 20 years of analog synth experience and expertise to be harnessed in affordable recreations of historic analog synths. The approach is to re-engineer the circuits to ensure they sound fantastic and are freed from the constraints of legacy components, we are not cloning but changing.

I am working with both the Chinese manufacturing and design teams and the Willich based product and social marketing teams. I am developing schematics, testing and fixing SMD prototypes, as well as creating some initial designs in THD. The partnership is very positive and exciting, we hope you enjoy the products once they are available!

What happens to AMSynths? We continue to develop and manufacture Euro Rack modules in low volume and in 2020 we remain focused on the SH05 project. We will continue to build and sell modules for this project, alongside our well established AM8060, AM8109 and AM8320 filters. The majority of AMSynths development effort is about re-engineering analog synths to a wider market with Behringer.

Which Behringer Projects are you working on? AMSynths cannot announce which projects we are in development with Behringer until they are formally announced. We will then provide details of the project along with our own sound and video demos.

Project 1 – 2600 This is a re-engineered ARP 2600 analog mono synth based on the original design with these key analog improvements:

  • Improved temperature stability due to use of SMD components
  • Improved tracking over 8 octaves (+/- 2 cents)
  • Tightly matched BJT and JFET’s throughout the synth, including VCO’s
  • Faster 4580 Op Amps throughout, with TL072 in key positions
  • Local power regulation for the discrete current mirrors in the Ring Mod and VCA
  • VCA Input offset removal by using a capacitor to DC couple the VCF input (not RM input)
  • Corrected VCA response from expo and linear inputs (same volume at max)
  • Removal of redundant HF trimmer in VCA
  • 3x timing ranges added to the ADSR and AR
  • Faster attack time on AR
  • Corrections to the original schematics
  • 4012 and 4072 filters with matched BJT
  • The LFO from the 3620 added, with UJT substitution
  • Careful power rail design to ensure separation and stability

The 2600 was announced by Behringer at NAMM 2020 and will be demonstrated at SuperBooth 2020.

Project 2 This analog synth is in development, schematics are complete and an initial prototype is being tested now.

Project 3 This analog synth is in development with some prototype circuits working and some being fixed.
