Deltalab Effectron ADM 1024

The Effectron ADM 1024 is a standout piece of digital gear from the early 1980s, marking a significant milestone in studio technology. Created during a time when RAM was prohibitively expensive, many early digital units had short delay times and were primarily designed for effects like chorus, flanging, phasing, and doubling. 

Deltalab, the manufacturer of the Effectron, was part of the vibrant Massachusetts hi-tech audio industry of the 1970s and 80s, alongside giants like Lexicon and Bose. Today, companies like Akamai, Analog Devices, B&W, and THAT Corporation continue this legacy. Richie DeFreitas, the founder of Deltalab, holds several patents, including one for Delta-encoding, a key technology that advanced digital audio by determining a digitally encoded signal based on the difference between present and past input values.

Effectrons are known for their quirky and character-rich sound. By adjusting the modulation depth and speed, they can produce a wide range of effects, from slow phase and deep flange to warbling chorus and pitch-bending, modulated delays. The ADM 1024, in particular, is famous for its killer flanging and phasing effects, as well as its infinite hold feature, which loops a sample in memory indefinitely. The Delay Factor control allows you to pitch-change the sample, adding even more creative possibilities.

This Deltalab Effectron ADM 1024 is in good condition! It has been tested and it works as it should. There is a fair amount of "rack rash" on the unit with one of the rack ears being bent. One of the buttons is missing on the front (see pictures) but the pusher is still working so you can engage the effect. The top of the "Delay Mix" knob is missing as well.
