On the back of Impact LX88+ are the connection points including:
USB port for power and data connection to your computer or iPad (via optional USB camera connection kit)
Foot switch jack, assignable (pedal not included)
MIDI Output. Can be routed individually for zones, from your DAW or directly from the LX88+
On/off switch
Power Supply socket: 9v 600mA, center positive, 2.1mm barrel connector, (PSU not included)
As a low powered USB device, Impact LX88+ works with all USB
devices that feature a Class compliant MIDI driver. This includes all
version of Windows from XP and higher, Apple OS X 10.5 and higher plus
Linux (as long as a USB MIDI driver package is installed).
And if you are often on the move you can easily hook your Impact
LX88+ keyboard to an Apple iPad using the iPad’s optional USB camera
connection kit (optional). Of course the Impact LX is powered by the
iPad so you can work away for as long as your iPad remains charged.
