Introduction • • • • • • • • • • • • • • • • MTV16 is an interface that converts midi control changes messages (sometimes called simply "midi controllers") into 16 analog voltages Output voltage range: 0…+5V (0V corresponds to midi data 0, +5V corresponds to midi data 127) Resolution of the voltages: 128 steps or 7 bit (based on the 7 bit midi data) the voltages are available as two pin heades with 10 pins each, each pin header has available 8 voltages and GND on two pins Two female connectors with 10 pin
Electrical safety / EMC compatibility MTV16 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. The manufacturer of MTV16 does not know the final assembly of the complete device in which the MTV16 is used as a part of the complete device.
Connections Power Supply (BU3) The MTV16 does not have a built-in power supply. Instead it uses a plug-in type external power supply (AC adapter). One reason for this feature is electrical safety. Keeping danger voltages (main) out of the MTV16 increases the electrical safety. Therefore an external power supply of high quality and safety should be used. If the unit is used in Germany the external power supply has to be VDE approved.

JP5 JP5 is a 16 pin double row pin header that is used to set the Midi channel and the Midi Control Change Number that is assigned to the first analog voltage output by means of jumpers. The numbering is from top to bottom (please refer to sketch on the previous page). The following table shows the relation between the jumpers 1 ...
Mounting Before MTV16 is put into operation the board should be fixed on a suitable support and built into a metal case (refer to EMC notes on page 4). The metal case should be connected to GND of MTV16. We recommend to use the GND terminal of the power supply socket for this connection. The MTV16 will work without housing too but in this case the assembly may exceed the EMC radiation limits in your country. The board measures about 78 x 67 x 25 mm.
