Antonus 2600 is a remake of the classic synthesizer ARP model 2600, more specifically the grey face version with transistor ladder filter. It is 20% size-reduced, to make it more portable. Hand-made in Barcelona, Spain. Dims are 402 x 200 x 18 cms, with the top lid attached.

The electronic circuit is a faithful recreation following the same schematics and components. Even being harder and more expensive to work with classic thru-hole technology, we chose to work in that way to replicate the sound and character of the original instrument, and this also ensures that the instrument can be serviced in the future.

2900 € Ex VAT is RRP UK price of THIS one (s/n 0107) is £2350 (GBP). Sale is via HMRC VAT margin scheme. NO VAT can be reclaimed by registered entities. Private buyers are unaffected.

EXPORT price is £2200 (GBP). Synth will be well bubble-wrapped and double-boxed...despatched via UPS with full insurance cover.

The 2600 character is so special, the sum of pros and cons is the soul of the instrument. We don’t want to “improve” or “update” anything to detract from the instrument's "mojo". We like the sound and character of the original one and that is the work ethic for us. This sound was part of music history, and was present in so many recordings from the 70’s. We love the warmth and the punch of the original instrument so we work with that in mind.

Faithful to the original – 100% analogue

We work with thru.hole components, using traditional soldering techinques, using “human scale” components. All IC’s are socketed using high grade turned sockets. No SMD components were used, only the small MIDI board have some SMD components. In the future you can change/repair any component of the boards like classic electronic thru-hole designs.

Using this build technique does make it slower and more costly to manufacture, but the sound and performance is well worth it.

Faithful design​

One of the main reasons to recreate the classic 2600 is that look and design. The design of the 2600 is something that adds a lot to the personality of the instrument.

The design of the cabinet follows the style of the original, retaining its shape and design, using Tolex and hardware both in the cabinet and in the front cover. The idea was respected in our work, despite the work and cost, because we believe that it is part of the special spirit of this instrument,

We love the portable sound synthesizer laboratory concept with a very musical approach, with that typical look of old musical instrument cases.

Some changes were made with the Antonus 2600, the first the form factor which is approximately 80% of the original size, which allows to fit in studios where space is more limited and also allows it to be stored inside a a travel suitcase. Something that with the original 2600 was impossible to fit in. It is now portable!

The front panel has black and orange silkscreen, specially scratch-resistant.

The sliders design has been changed to a LED-lit design that allows a very visual and direct experience Also since 2021 the new translucent slider knobs, to add better touch feeling and keeping the illuminated colour. 

The brightness is adjustable by front trimmer. High quality faders with smooth and precise travel with 45mm travel to ensure precision during playing the instrument

The spring reverb used is the long version, used in the early units of the 2600. (In later models of the 2600 gray face the reverberation was shorter spring / time).

Connecting a classic with the present

In the Antonus 2600, standard MIDI features are incorporated to achieve integration with current studios and configurations. Additionally a GATE input compatible with most systems, unlike the GATE input of the genuine one that was much more restrictive design. Now we ensure a lot of more compatibilty with analogue instruments of today.

Since 2021 the Antonus 2600 has a new duophonic interface with enhaced features.

  • Monophonic and Duophonic modes
  • Upgrade to 2 auxiliary CV outputs  and 2 GATE ouputs
  • Extra LFO routable to any CV output (pitch or AUX) with 4 different waveforms and wide frequency range.
  • Pitch Portamento
  • Interval latch and HOLD functions
  • All parameters are CC and can also be programed by user.

Like the previous version it recognizes MIDI note and pitch-bend. It also has an additional CV input to control the internal tuning bus of VCO’s and VCF. It is mixed  with the MIDI-CV signals so you can mix both for creative techniques like transposing, or different scales.

As can be seen from the photos, there is a MIDI keyboard supplied in the package, plus a manual, 5 patch leads and a mains cord (it runs @ 220Vac).
