Microphone signal: This can be a signal from either a dynamic or condenser microphone.
Use the XLR input to transfer microphone signals. Your microphone could come with its
own XLR connector as well. Use an adapter if this is not the case.
Line signal: This signal is best transferred to the input via a balanced or unbalanced
6.35mm jack plug. A balanced plug carries three signals (tip, ring and sleeve), an
unbalanced signal carries two (tip and sleeve). Line signals typically come from keyboards,
digital pianos, PA or DJ mixers, a CD player and other, similar devices. It is possible your
source device does not feature the correct connector. If so, use an adapter cable.
Guitar signal (Hi-Z): This button is part of the input channels and should be enabled when
you want to connect a guitar or any other instrument with a fixed cable to the interface.
Generally speaking, these instruments carry a signal that’s too weak to be amplified via a
line or microphone input as it may be accompanied by static and a dull sound.
If you’re using other external equipment such as preamps or multi-effects, please check
carefully how the outbound signal is sent out. It may be pre-amplified to a line signal, in
which case the Hi-Z functionality is not required.
Outputs
The Centro 2i2o is fitted with two balanced XLR outputs that can generally be connected to
your studio monitors in stereo. Nine out of ten times, studio monitors have been fitted with
their own built-in amplifier (which will require a separate power supply).
If this is not the case, or you’d like to connect another pair of speakers to a different device
such as a PA mixer, the outputs can be connected to it as well. The interface sends out line
level signals.
Kensington lock
This device comes with a connector that can be used with a Kensington lock. A Kensington
lock is a special lock that uses a mechanism in a specific cut-out in a device’s housing to
lock the device. This
discourages
theft.
Power supply
The Centre 2i2o is bus-powered via the USB port. A special power supply is not required.
The average laptop or computer should be able to supply ample power to guarantee
correct operation. Always use the included cable to connect the interface to your laptop or
computer.
