1. Introduction
The ARCEX is an audio only extender designed to take the
ARC audio of a display to an amplifier or other ARC enabled
device and transmit it in full bandwidth up to 90m (295ft) over
category cable. CEC transmission is supported so the display’s
remote can be used to control the volume of the amplifier. The
EXARC also supports optical S/PDIF transmission up to 150m
(492ft) at 96 kHz., and 90m at 192 kHz. The ARCEX is
designed to be a simple plug and play device to get ARC from
the display back to the ARC enabled amplifier or other ARC
device that is too far away to use a traditional HDMI cable.
2. Features
•ARC Audio or Optical S/PDIF is extended over single
category cable
•Audio formats include: PCM 2.0 or Dolby/DTS 5.1
•At the lower sampling rates of 96kHz. or below, the
distance is increased to 150m (492ft)
•At the higher sampling rates of 172kHz. and 192kHz.,
the distance is 90m (295ft)
•Supports CEC for amplifier volume control, etc.
•Compact size
•DIP switch enables optical S/PDIF if ARC is not
available (CEC is lost in this mode)
•Power input is designed to use Micro USB so that
available USB ports can be used to power the RX, TX
or both

6. Application Example (ARC Mode)
***The Switch on the TX should be set to ARC
***Also note that it many displays will have a port
marked “eARC”. eARC is backwards compatible with
ARC. Some displays default to ARC when this is
disabled, other may vary. It may become important to
familiarize yourself with the display’s functions.

7. Application Example (Optical)
***The Switch on the TX should be set to “SPDIF”
8. Troubleshooting
No
Power
- Verify power at both ends (make sure power LED) is
illuminated. If you are using the display’s USB port, it is
possible that it does not have enough current to power the
TX or there may be a setting in the display’s menu that is
affecting it
- Use the supplied USB Power supplies
- Verify that the USB Power supplies are operation by
using a power bank or known USB supply
No
Sound
- Verify power at both ends (see above)
- Verify that the switch setting is in the mode you are
wishing to use
- If the ARC enabled amplifier does not have downmix
capabilities, you must change the audio settings in the
display’s menu, to “PCM”.
- When using optical (S/PDIF) the same rules apply to this
format as well if the amp/audio device does not downmix
