Thank you for purchasing the MIDI Solutions MultiVoltage M8 8-input MIDI Merger.
The MIDI Solutions MultiVoltage M8 merges MIDI data from eight MIDI inputs to its two MIDI outputs, and may be
chained together with other MIDI Solutions Mergers for as many inputs are required. The MIDI Solutions MultiVoltage
M8 is MIDI-powered and requires no batteries or power supply to operate. It is compatible with products that follow
both the 5V and 3.3V MIDI specifications.
INTRODUCTION
Connect the MIDI Outs or Thrus of the sending MIDI devices to the MIDI inputs (
through
) of the M8. Connect
MIDI
and
of the M8 to the MIDI Ins of the receiving MIDI devices. The number of MIDI Solutions products
that can be chained together is dependent on the specifications of the MIDI output port supplying power – for more
information see the MIDI INDICATOR LED section. Since some products make use of unused pins 1 and 3 to pass
phantom power, connections to these pins are provided between the
and
jacks. These pins are not
connected to the M8's internal circuitry. It is recommended that the current passing though these pins be limited to 1
amp.
Power is provided to the M8 by the device that is connected to its first MIDI input,
. If a device does not provide
power it can be connected to
-
. All MIDI messages appearing at the M8's MIDI inputs are merged to its MIDI
outputs
and
.
The MIDI Indicator LED will light as soon as the sending device is turned on, and flashes briefly whenever MIDI data
passes through the unit. If the MIDI Solutions M8's operating voltage drops below the threshold at which it is able to
provide a MIDI standard drive current of 5 mA, its LED will produce a steady on/off warning flash. After rising above
this threshold the LED will continue to produce a steady on/dim flash for 10 seconds. Since the voltage always rises
above this threshold on power up, a steady on/dim flash will always be visible for 10 seconds; during this time the unit
is operating normally and providing the standard drive current. If the M8's operating voltage is below 4V its LED will
produce a dim flash every four seconds, this signal is for diagnostic purposes and does not affect its operation.
