SN 500710

The System 100 is a great and classic analogue synth It's a beautiful semi-modular monophonic synth consisting of 5 module components: the Synthesizer 101, Expander 102, Mixer 103, Sequencer 104, and Monitor Speakers 109. The Synthesizer 101 section is the heart of the system, from which you could add-on any of the other modules of your choice. Different combinations of these components can be used to create systems of varying potential.

The Expander 102 section is a keyboard-less version of the 101, designed to stand upright and behind the main Synthesizer 101. More than one Expander 102 can be added to make your system fatter and fatter! The Expander is identical to the Synthesizer except that it replaces Portamento/Glide effects with a Sample-and-Hold feature for the LFO, the Noise gen. is replaced by a Ring Modulator, and the A-440 tuning osc. is replaced by weak/strong sync inputs and a mix-in jack. The Expander is an excellent way to add more oscillators and synth effects to a System 100. The oscillators can be synced if you have both modules. The 101 and 102 are already internally patched and ready to produce sounds, but that can be bypassed by external patching.


The System 100 is a great sounding analogue system with the classic vintage Roland sound. Although it is itself an impressive system, Roland took the concept a step further developing additional modules for the System 100m. Although the 100m has greater patching freedom, it doesn't sound as warm as the 100. Apparently the 100 has the same filter chip as a TB-303, but it certainly doesn't produce the same sound, the System 100 sounds better! Whatever configuration you find a System 100 in, they are all powerful, warm, and useable machines!

Condition

In very good condition despite showing some signs of age and wear. The print on the faceplate is still very clear and mostly damage free but there are some scratches and patches where the paint has cracked underneath the control panel, the later possibly caused by some oxidisation. See photos for more information on cosmetic condition.

Voltage Information

100v Japanese model. For customers on 220/240v supplies we will supply a high quality step-down transformer free of charge with your purchase - let us know if this is not required. On North American mains (115/120v supplies) this unit will run without a transformer (we run all our tests using 120v power); however, a step-down transformer is recommended for extended use. We do not recommend using cheap, generic Chinese mains transformers - please ask if you have any questions about powering this unit.
