RX microphone & speakers
ALIF units can support a microphone as
well as speakers providing the necessary
connections have been made between
the ALIF TX unit and the host computer.
3 Once the unit has been fully connected and powered on, access the RX System
Configuration page to check that the
Audio Input Type
setting matches the connection
that you have made to the port:
line
,
mic
or
mic boost
(the latter pr20dB gain).
To connect a microphone (or line in) and/or speakers
1 Connect the lead from a mono microphone to the 3.5mm socket labeled on the
rear panel.
2 Connect the lead from stereo speakers to the 3.5mm socket labeled on the rear
panel.
RX USB devices
The ALIF RX unit has four USB ports
to which peripherals may be connected.
The ports are interchangeable. To
connect more than four peripherals, one
or more USB hubs may be used. The
total current that may be drawn from
the USB ports is 1.2A, which should
be sufficient for a keyboard, mouse (no
more than 100mA each) and any two
other devices (500mA maximum each). If
more power for USB devices is required, use a powered
USB hub.
To connect a USB device
1 Connect the lead from the device to any of the four
USB sockets on the rear panel of the ALIF unit.

Supported USB Devices
The transmitter unit uses True Emulation technology to emulate the signals of certain
USB peripherals to the computer. This means that those peripherals appear to the
computer to be permanently connected, even when the receivers are switched
elsewhere. This enables faster keyboard and mouse switching and allows for more than
13 identical USB devices. If the keyboards and mice are identical across the connected
receivers, they are only enumerated once by the host. The following limitations apply:
• Keyboards, mice and other HID devices are supported.
• Storage devices (i.e. flash drives, USB hard disks, CD-ROM drives) are supported, but
they may operate more slowly than with a direct connection.
• Isochronous devices (including microphones, speakers, webcams and TV receivers) are
not currently supported.
• Many other devices (such as printers, scanners, serial adapters and specialist USB
devices) will work, but due to the huge variety of devices available, successful
operation cannot be guaranteed.
• If a device cannot be made to work, please contact Adder technical support as a
special entry within the advanced configuration may solve it.
