Why Green Audio?
It’s simple stuff. After more than 20 years in the consumer electronics industry, we wondered if there were
more efficient ways to deliver the products most people use.
Green Audio was founded in 2016 with an eye toward reduced environmental impact and labour
efficiencies. We’ve developed a growing line of products to help you enjoy your leisure time at home with
minimal impact on our planet.
Our mandate is to significantly reduce environmental impact by delivering commonly used consumer
electronics products in smarter bulk packaging. We start by reducing the overall footprint of our
packages. Smaller and lighter, our packages consume less non-renewable resources to produce and
transport. If you’re going to use more than one of something, why buy them individually? Bulk packaging
reduces overall size by up to 50%.
We go further by eliminating plastic packaging altogether and by printing single colour on plain cardboard
(as opposed to retail “beauty boxes”). And we only include essential items with our products, i.e., there’s
no frivolous material inside.
Next, we make our packages easy to open, reducing installation time and saving you money. They’re also
designed to be reusable.
Finally, our “waste” is 100% recyclable cardboard. It’s easy to recycle and less likely to end up in a landfill.
Fortunately, this doesn’t require compromising quality or performance. We access the same factories and
designs as our competition, delivering competitively priced products of high value. We just like to think
we do it in a more caring way.
Save time. Help the planet. Thanks for being Green.

Operation
Manual Switching
• Set the unit to manual switching mode by pressing the front panel Auto Source button for three
seconds. The Mode LED will illuminate green.
• Manually select the desired HDMI source by pressing the front panel Auto Source button.
Automatic Switching
• Set the unit to automatic switching mode by pressing the front panel Auto Source button for three
seconds. The Mode LED will illuminate yellow.
The switcher follows the below logic when automatically switching:
• Upon detecting a new input/source connection, the switcher will automatically switch to the new
source.
• If an active source is lost or powered down, the switcher will automatically switch to the first sensed
input starting at input 1 and cycling up (1 > 2 > 3 > 4).
• Upon switcher power reboot, the switcher will automatically switch to the last source. If that
input/source connection isn’t present, the switcher will automatically switch to the first sensed input
starting at input 1 and cycling up (1 > 2 > 3 > 4).

IR Remote Control
• Connect an IR receiver to the 3.5mm IR port on the switcher.
• The included IR remote control features three sections: the top section

source and display devices provided they support compatible CEC commands.
RS232 Control
• Connect a 3.5mm to DB9 RS232 cable to the 3.5mm RS232 port on the
switcher.
• Verify the control system is configured to the proper RS232 parameters:
