AJH Synth - Synth System 9U

The AJH Synth System 9U is a versatile, pre-configured complete system. An impressive proof of Allen's creativity.

This System is a sound-monolith. Carefully matched to each other, the 9U expands the functionality of the smaller 6U system even further and forms a modular symbiosis of modules in a Eurorack case that are not only "tried & tested" but also "ready to go" for use in your studio.

In contrast to the 6U system, the 9U offers an additional VCO, VCF, VCA and more modulation on three rows each. For example, a complete minimod voice is also possible, but can be supplemented by a significantly different sounding, additional voice. This is provided, among other things, by the Wave Swarm dual waveform animators, a wavefolding diode filter, and a clockable, CV-controllable multi-waveform LFO.

Among other things, this makes a two-voice polysynth possible, with each voice having 2 VCOs, 2 envelopes of its own, matching waveform animator (Wave Swarm), LFO, VCF and VCA. In addition, either two 2-VCO monosynths that can be clearly distinguished from each other in terms of sound or three  separate monosynths can be created. Or a monstrous sounding 4 VCO monosynth with 2 sub-octaves. The AJH 9U is a real powerhouse of sonic and technical possibilities to go on an intuitive, modular journey.

Since the choice of patch cables is a matter of personal preference, the system is shipped without patch cables. The manufacturer recommends purchasing the following cables: 10x 25-30cm; 10x 50-60cm; 4x 80-90cm.
