1. Important Information
Thank you for purchasing the FSX DUAL adapter. Please take a
moment to read through this ‘important information’ chapter before
proceeding. Users should also refer to the Support and Disclaimer
Information chapter for detailed writings regarding warranty & support
information and other terms and conditions.
WARNING:
Please be aware that the FSX DUAL adapter features internal audio
amplifiers. These allow the computer audio strength to be boosted to
the levels required for driving ‘high-impedance’ Aviation Headsets.
Users should therefore not connect ‘low-impedance’ (ie: non-
Aviation) headsets to the device as damage could result.
Cautions and basic care instructions
•Ensure that the FSX DUAL volume is turned down before connecting
the Headset.
•Users should bring the devices volume up gradually until a
comfortable audio volume has been achieved. High audio volumes
and prolonged use can result in hearing loss.
•Do not attempt to disassemble or alter any part of this device.
•Stop operating the device immediately if it emits smoke or noxious
fumes.
•Do not allow the device to come into contact with, or become
immersed in water or other liquids.
•Do not store the device in humid or dusty environments.
•Avoid using, placing or storing the device in places subject to strong
sunlight or high temperatures, such as the dashboard or trunk of a
car.

[4]
•Be careful not to subject the device to strong impacts.
•Avoid placing the device in environments where it may be subject to
strong electric and/or magnetic fields.
•Clean the device with a soft, absorbent cloth. Do not use cleaning
substances containing alcohol, benzene, thinners or other flammable
substances.
2. Description
Flight simulation will never be ‘as real as it gets’ unless it ‘sounds and
feels’ authentic. The FSX DUAL adapter helps to achieve this goal by
bringing flight simulation audio into the 21st century. Pilots, gamers or
any aviation enthusiast can now use their aviation headsets with any
USB enabled computer.
FSX DUAL is designed to be as easy to use as possible –no additional
software, no batteries, no external power sources - just one standard
USB cable. Users can quite simply ‘plug and play’. The device features
two channels, allowing for inter-communication between two separate
headsets. Each user has their own volume control option and also a
separate squelch control which allows for varying degrees of
background noise elimination. When users have finished working with
the device, simply unplug it, and the computer will revert back to its
original audio settings.
Note: Plug in FSX DUAL before launching any programs you intend to
use it with.
