Thank you for purchasing the MIDI Solutions MultiVoltage Quadra Merge.
The MIDI Solutions MultiVoltage Quadra Merge merges MIDI data from four 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 Quadra
Merge 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 Quadra Merge.
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 Quadra
'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 Quadra Merge by the device that is connected to its first MIDI input,
. If a device
does not provide power it can be connected to
,
, or
. All MIDI messages appearing at the Quadra
'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 Quadra
'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.
