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 positive and exciting, we hope you enjoy the products once they are available!

What happens to AMSynths? Due to CORVID-19 AMSynths has had to be paused as our workshop is closed. We hope to re-open the business in the second half of 2020 with a focus on the SH05 project, alongside our well established AM8060, AM8109 and AM8320 filters.

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 and improvements to the Reverb and Noise Source are underway.

Project 2 This analog mono synth is in development, schematics are complete and a second prototype is being tested in the UK.

Project 3 This analog modular synth is in development and in the final stage of testing in the UK.
