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 ribbon cables can be used to wire the outputs to obtain

removable connections.

• The voltages are controlled by 16 subsequent midi control changes messages on the same

midi channel.

• The midi channel that is used to control the 16 outputs is adjusted by means of four jumpers.

• The control change number of the first output can be set to 0, 16, 32, 48, 64, 80, 96 or 112

by means of three jumpers.

• MTV16 is equipped with Midi In and Midi Thru. The incoming Midi messages are forwarded

to the Thru output without any changes. In this way several MTV16 can be linked together.

• MTV16 is available only as an assembled and tested pc board.

• The pc board measures are about 78 mm (length) x 67 mm (width) x 25 mm (height).

• Several mounting holes with 3 mm diameter are available for mounting the pc board to a

suitable base e.g. with distance sleeves or spacers and screws.

• We do not offer a suitable housing as this would have to be completely different for various

applications.

• An external power supply (7-12VDC@min. 100mA) is used. Within Europe the wall outlet

power supply adapter for 230V mains voltage and European type mains plug is included with
the MTV16. In other countries the power supply has to be purchased by the user in his
country. If there is a Doepfer representative in your country please ask the representative if
the power supply is included in your country.

• connectors for power supply, midi in and midi out are available as sockets on the pc board

• Midi cables and cables/wire for the analog voltages are not included but can be ordered

together with the MTV16 (additional charges)

Installation of the MTV16 requires electrical/electronical knowledge by the user. Please leave
the installation of MTV16 to an expert if you are not familiar with electronics. We take back only
MTV16 modules in the original state, i.e. without solder residues, without scratches and so on.

Please pay attention to the warranty notes on page 4. Ignoring these notes causes warranty
loss and the right to return the goods.
