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. 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 MTV16 has to be a closed type (in Germany a
power supply with VDE approval is required). Normally an AC adapter with plastic case is used.
It is not allowed to use open power supplies with open mains voltage access (e.g. via mains
lead, pcb tracks, electronic parts).
On the MTV16 board preventing measures against electromagnetic radiation are met (e.g.
RF filters at the power supply input). But it is impossible to estimate to what extend the
components added by the user affect the EMC properties of the complete assembly.
Therefore the complete device has to be shielded 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 MTV16.
Warranty notes
• The 16 control voltages are outputs and should connected only to inputs of other devices!
• Only high impedance inputs ( > 10kOhm) should be connected to the MTV16 outputs. The
circuits connected to the MTV16 outputs have to be free of any voltage, i.e. the inputs are not
allowed to have any active voltage level (e.g. GND, +5V).
• But the MTV16 outputs have a limited short circuit protection (100 Ohm serial resistors).
Connection an output by mistake to GND or any voltage between GND and +5V will not
destroy the MTV16. Shortening two MTV16 outputs will also not destroy anything.
• Applying any negative voltage or a voltage beyond +5V to one of the analog outputs will
destroy the MTV16.
• Do not apply any voltage to the pin headers with jumpers that are used to adjust the MTV16
parameters (e.g. Midi channel, control change number) but use only jumpers!
• We recommend not to solder directly to any of the pin headers but use female connectors to
make the connections between the MTV16 and your application. MTV16 includes two 10 pin
ribbon cables (about 30 cm each) for this purpose.
• Carry out all connections in the off-state of the MTV16 (i.e. without power supply) !
• The MTV16 electronics is an electrostatic sensitive device. Avoid any electrostatic charges !
• Avoid short cuts !
• Ignoring any of these items will cause warranty loss !
• Return of the MTV16 within the 2 weeks return time limit (valid only in Germany) is only
possible if all these items have been met. Return of used cable sets is not possible.
