s Guide Important note The DIY Synth kit is planned for experienced users only who are familiar with both electronics and analog synthesizers. It is definitely unsuitable for beginners ! For example we will not be able to offer the service to repair a customers assembly if it does not work as it should, or to make individual suggestions how to wire the board for special applications. We have to emphasize this fact very clearly in advance to avoid unsatisfied customers who will have problems getting their synth to run. If you are not sure if your skills are sufficient please return the DIY synth kit for money refund before you start to wire the board ! Electrical safety / EMC compatibility The DIY Synth kit is a so-called OEM product (OEM original equipment manufacturer) that cannot be used independently but has to be combined with additional electrical or electronical equipment to become a working device (suitable controls, switches, sockets, power supply, case/housing and so on). The manufacturer of DIY Synth kit does not know the final assembly of the complete device in which the DIY Synth kit is used as a part of the complete device. The final responsibility with regard to electrical safety and electromagnetic compatibility is up to the user who is assembling the complete device. Please pay attention to the following items: The power supply used in combination with the DIY Synth kit has to be a closed type. It is not allowed to use open power supplies with open mains voltage access (e.g. via mains lead, pcb tracks, electronic parts). For example the A-100 miniature power supply (A- 100MNT) can be used. As no radiation is expected due to the 100% analog low frequency circuits no preventing measures against electromagnetic radiation are met on the DIY Synth board. But it is impossible to estimate to what extend the components added by the user affect the EMC properties of the complete assembly (e.g. switching power supply). Therefore it is recommended to shield the complete device against electromagnetic radiation (incoming and outgoing). These demands are normally met by a closed metal case that covers the complete assembly. The metal case should be connected to GND of the DIY Synth kit. User'

3 DIY Synth Kit Warranty ? All connections have to be carried out in the off-state of the DIY Synth kit (i.e. without power supply) ? The DIY Synth kit is an electrostatic sensitive device. Avoid any electrostatic charges ! ? Do not solder directly to any of the pin headers but use connectors to make the connections between the DIY Synth kit and your application. ? Use only a power supply that corresponds to the specifications given in this manual (i.e. +12V/GND/-12V). ? Applying a negative voltage less than C12V or a positive voltage beyond +12V at any of the inputs may destroy the circuit. ? Avoid short cuts while DIY Synth kit is powered (e.g. caused by metallic or conducting supports) ! ? Ignoring any of these items will cause warranty loss ! ? Return of the DIY Synth kit within the

2 weeks return time limit (valid only in Germany) is only possible if all these items have been met. DIY Synth kit that have been soldered or modified by the customer cannot be taken back. Electronic knowledge is required to install and operate the DIY Synth kit. If you are not sure whether your knowledge is sufficient please consult an expert. We cannot take back kits that became defective because of wrong installation or wrong connection of the controls or voltages. We also cannot take back modules or cables which have been soldered by the user. DIY Synth Kit Page
