TTSH (ARP 2600 clone)

TTSH front panel

The short "TTSH" stand for "Two Thousend Six Hundred", aka the famous ARP 2600. And this TTSH is a size reduced (about 70%) clone of this semi modular ARP synthesizer built in different versions from 1970 to 1981. The vintage ARP 2600 was used by many synth musicians in those days. It also well known to be the synthesizer that made the R2D2 talk.
The TTSH boards wer available from late 2014 till 2017 as a DIY project. Some people offered their work to assemble it for the non soldering synthesizer enthusiasts. It is electronically a quite faithful reproduction of the original. There is the original Moog filter (ARP module 4012 1970-76) and the later integrator cascade 4-pole low-pass filter (ARP module 4072, 1976-81 available. In order to work in a well scalled manner, you have to recalibrate the filter trimmers on the main board when switching the filter submodules.

My unit was bought used. It is from the revision 3 that was released December 2016. It is the latest version. On my unit there is also a added modification to trigger the envelopes with less than the 10 V needed on the original ARP 2600.

It got the following sections that are quite well chosen pre connected:

  • 3 VCOs:
    • VCO1: saw and square waveshapes
    • VCO2: triangle, saw, sine and pulse waveshapes
    • VCO3: saw and pulse waveshapes
  • Noise generator with variable noise color from low frequency (red), pink to white noise.
  • Ringmodulator
  • 4-pole VCF
  • VCA
  • Spring Reverb
  • ADSR Envelope
  • AR Envelope
  • Sample & Hold (also available as retrigger clock)
  • Preamplifier
  • Envelope Follower
  • Voltag Processor for mixing, inverting and lag processing
  • Electronic Switch
  • Multiple Connectors
  • Output Mixer
  • 2 built in speakers

Connecting a cable at one of the sockets (here all 3.5 mm) will brea the connection from the output labeled below. So you can add special need connection, and don't have to patch the most typical connections at all, as they are already patched internal for you. This saves time, and helps avoiding spaghetti salat in front of the panel.
