Introduction
Congratulations on your purchase of the
MidiStream
UHF wireless MIDI system. The
MidiStream
system is very easy to use, but please take a few moments to read through the manual to avoid any
operational difficulties.
MidiStream
has been designed specifically to address the problems unique to MIDI data transfer. It
combines a high data rate with extremely low latency and low dropout rate. Should dropouts occur due
to going out of range or interference from other sources,
MidiStream
is designed to handle these
events without leaving notes stuck on.
The
MidiStream
system works in the 868 to 870MHz pan European licence free band. At the present it
is available with one frequency of 869.85MHz which means that you cannot use two
MidiStream
units
close to one another, however we plan to make other frequencies available in the future to enable
multiple units to be used in the same vicinity.
About the Transmitter Unit
MIDI In socket
Connect your keyboard, wind controller or other MIDI device to this input socket using a standard MIDI
cable.
Antenna
The antenna fitted on the
MidiStream
transmitter is not removable, do not attempt to unscrew it! Try to
ensure that the antenna is straight when operational and if possible is placed away from other solid
objects, particularly metal ones
.
On/Off switch
When this switch is on, the
MidiStream
transmitter is operational and waiting for MIDI data.
LED
This LED has four functions:
1) The LED will give a steady glow when the
MidiStream
transmitter is on,
2) When MIDI data is received the led will flicker in response to the incoming MIDI signal.
3) If the battery voltage is low (6.5 volts or less), this LED will flash regularly on and off
4) If the unit enters power save state, the led will blink briefly every two seconds
Changing the battery:
When the LED indicates that the battery voltage is low, it is time to change the battery.
Unscrew the knurled knob on the bottom of the unit and open the flap. Turn the unit so that the battery
falls out under it’s own weight, but try to catch it so as not to stress the connecting wires.
If the battery voltage falls below about 4.5 volts the
MidiStream
transmitter will no longer work.
About the Receiver Unit
Power on/off switch
Push this switch
IN
to turn the unit on.
DC IN 9-12V
Plug the supplied power adapter into here. The unit will take an adapter with an output in the range of
9-12V either regulated or unregulated. The socket is a 2.1mm type with centre positive. Do not use an
adaptor with an output voltage higher than 12V, and the
MidiStream
must not share an adaptor with
any other device. Failure to observe this will invalidate your warranty, and will probably damage the
other device, the
MidiStream
and/or the power supply
.
