Thank you for purchasing the Luxi Electronics AHD-
211 4k HDMI Audio Extractor/Communicator. Please
read through this manual before using the product.
Power options:
This product can draw power from the source device
via HDMI cable or from the optional external power
supply. To determine if the source device has enough
power to power this device, connect this device in
between the source and display
devices via a short HDMI cable. If a normal picture appears on screen, then this
device can get enough power from the source device and no need for an external
power supply. If no normal picture on screen, then it needs an external power
supply. You can buy the optional Luxi power supply (P/N 69-001-01) or use any
standard 5 V DC power supply with at least 0.5 A output current capability.
Power wire and plug preparations:
Unplug the power supply from the outlet first; cut off the original DC plug if
using a non-Luxi power supply, separate the two wires for about 1” (2.5
cm) long, strip off the wire insulation precisely 3/16” (5 mm) from the end;
too short a lead won’t provide enough for
the plug screws to catch; too long a lead
may create short circuit). Identify the
positive and negative leads; Luxi power
supply has a white strip on the positive
wire. If not sure, use a multi-meter to
test it. Insert the leads all the way to the end of the 3.5 mm captive
screw plug (provided with each AHD-211) with the correct polarity
(positive on left side), use a small flat head screw driver to tighten the 2
locking screws securely. If multiple of these products are used in the
same location, one Luxi external power supply can power up to 5 units. Use extra insulated wires (18
AWG to 22 AWG) daisy-chain the multiple power input captive screw plugs, connecting all positive side
together, and connecting all negative side together.
Where to apply the product and how to connect the cables:
This product is designed to be plugged in directly onto the output connectors on the back of the source
device. The HDMI output of this product is connected to the display with an HDMI cable. The S/PDIF
output is connected to an audio device via a coax RCA cable. The analog audio output is connected to
a power amp’s line level input via a 3.5 mm mini cable. Note: it CANNOT drive a headphone.
How the product functions:
All 3 audio outputs (HDMI audio, S/PDIF and analog audio) are live simultaneously. The display or the
Audio Extractor’s EDID would request the source to send 2 channel audio. The Audio Extractor
regenerates the same HDCP key of the display. The Audio Extractor works without a display. When
the HDMI Return Audio is in effect, the S/PDIF and analog audio outputs will be muted. This is the
limitation of the HDMI specs. The product also alters DDC communication timing and corrects HDCP
and EDID communication collisions.
