Thank you for purchasing the MIDI Solutions MultiVoltage Merger.
The MIDI Solutions MultiVoltage Merger merges MIDI data from two 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 Merger 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 (
and
) of the
. Connect
and
of the
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
's internal circuitry. It
is recommended that the current passing though these pins be limited to 1 amp.
Power is provided to the MIDI Solutions Merger 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
'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
'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
'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.
