About the DA2HD4KPLUS,DA4HD4KPLUS, and DA6HD4KPLUS
The Extron DAHD4KPLUS Series are one input, multiple output HDMI distribution
amplifiers for 4K signals. They distribute one 4K input signal to two (DA2HD4KPLUS), four
(DA4HD4KPLUS), or six (DA6HD4KPLUS) simultaneous outputs. They support data
rates up to 18.0Gbps, including computer and video resolutions up to 4096x2160@60Hz
and 1080p@60Hz 4:4:4 with Deep Color, 3D, Lip Sync, HDR (high dynamic range), and
HD lossless audio formats.
NOTE: Extron strongly recommends compatibility testing while designing, and before
installing any 3D or HDR system. There are several unique 3D and HDR formats in
use by source devices and display manufacturers. The level of 3D and HDR product
support is governed by pixel clock, signal format, and communication between
source and sink devices. Please contact an Extron Application Engineer for more
information.
All three models feature EDIDMinder, which maintains continuous EDID communication
between connected devices, and KeyMinder, which continuously authenticates HDCP
encryption between all devices, ensuring the simultaneous distribution of source content to
all displays.
The DAHD4KPLUSdistribution amplifiers provide automatic input cable equalization up to
15feet (4.5meters) for 4K @ 60 Hz signals, automatic color bit depth adjustment, and allow
outputs to be independently muted.
Front panel LEDs provide immediate confirmation of HDCP authentication and signal
presence.

1. Cut the DC output cord to the length needed.
2. Strip the jacket to expose 3/16inch (5mm) of the conductor wire.
ATTENTION:
• The length of the exposed wires in the
stripping process is important. The ideal
length is 3/16 inches (5 mm). Any longer and
the exposed wires may touch, causing a short
circuit between them. Any shorter and the
wires can be easily pulled out even if tightly
fastened by the captive screws.
• La longueur des câbles exposés est
importante lorsque l’on entreprend de les
dénuder. La longueur idéale est de 5 mm
(3/16 inches). S’ils sont trop longs, les câbles
exposés pourraient se toucher et provoquer
un court‑circuit. S’ils sont trop courts, ils
peuvent être tirés facilement, même s’ils sont
correctement serrés par les borniers à vis.
• Do not tin the wire leads before installing into
the connector. Tinned wires are not as secure
in the connector and could be pulled out.
They may also break after being bent several
times.
• Ne pas étamer les conducteurs avant de
les insérer dans le connecteur. Les câbles
étamés ne sont pas aussi bien fixés dans le
connecteur et pourraient être tirés. Ils peuvent
aussi se casser après avoir été pliés plusieurs
fois.
3. Ensure the connections have the correct polarity as shown in the figure above. The wire
with ridges is the ground wire.
4. Slide the exposed ends of the wire into the captive screw connector and secure by
tightening the screws.
5. Use the supplied tie wrap to strap the power cord to the extended tail of the connector.
ATTENTION:
• Always use a power supply provided by or specified by Extron. Use of an
unauthorized power supply voids all regulatory compliance certification and
may cause damage to the supply and the end product.
• Utilisez toujours une source d’alimentation fournie ou recommandée par
Extron. L’utilisation d’une source d’alimentation non autorisée annule toute
certification de conformité réglementaire, et peut endommager la source
d’alimentation et l’unité.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air
handling spaces or in wall cavities.
• Sauf mention contraire, les adaptateurs CA/CC ne conviennent pas à une
utilisation dans les espaces d’aération ou dans les cavités murales.

DA HD 4K PLUS Series • Installation 7

ATTENTION:
• If not provided with a power supply, this product is intended for use with a
UL Listed power source marked “Class 2” or “LPS” rated 12 VDC, 0.5 A
minimum.
• Si le produit n’est pas fourni avec une source d’alimentation, il doit être
utilisé avec une source d’alimentation certifiée UL de classe 2 ou LPS avec
une tension nominale de 12 Vcc, 0.5 A minimum.
• The installation must always be in accordance with the applicable
provisions of National Electrical Code ANSI/NFPA 70, article 725 and the
Canadian Electrical Code part 1, section 16. The power supply shall not be
permanently fixed to building structure or similar structure.
• Cette installation doit toujours être conforme aux dispositions applicables
du Code américain de l’électricité (National Electrical Code) ANSI/NFPA 70,
article 725, et du Code canadien de l’électricité, partie1, section16. La
source d’alimentation ne devra pas être fixée de façon permanente à une
structure de bâtiment ou à une structure similaire.
• Power supply voltage polarity is critical. Incorrect voltage polarity can
damage the power supply and the unit. The ridges on the side of the cord
identify the power cord negative lead (see the power wiring diagram on
page7).
• La polarité de la source d’alimentation est primordiale. Une polarité
incorrecte pourrait endommager la source d’alimentation et l’unité. Les
stries sur le côté du cordon permettent de repérer le pôle négatif du cordon
d’alimentation (voir power wiring diagram).
• To verify the polarity before connection, plug in the power supply with no
load and check the output with a voltmeter.
• Pour vérifier la polarité avant la connexion, brancher l’alimentation hors
charge et mesurer sa sortie avec un voltmètre.
DA4HD4KPLUS and DA6HD4KPLUS
BIEC power inlet — Use the provided female IEC cable to connect
the female IECinlet to a 100‑240VAC (50or 60 Hz) power source
(see figure2 on page6).
Connecting Input Source
CHDMI input — Use an HDMI cable to connect the input source to the rear panel
female HDMI port (see figure2).
NOTE: Secure the input and output HDMI connectors to the distribution amplifier
with the provided LockIt HDMI lacing bracket (see Securing the HDMI
Connector on page9).
The input follows HDMI2.0b specifications, supporting data rates up to 6.0Gbps per

Securing the HDMI Connector
Follow these instructions to secure the input and output connectors to the distribution
amplifier with the LockIt HDMI lacing bracket provided:
1. Plug the HDMI cable into the rear panel port (1).
2. Loosen the HDMI connection mounting screw
from the panel enough to allow the LockIt
lacing bracket to be placed over it (2). The
screw does not have to be removed.
3. Place the LockIt lacing bracket on the screw
and against the HDMI connector, then tighten
the screw to secure the bracket (3).
ATTENTION:
• Do not overtighten the HDMI
connector mounting screw. The
shield it fastens to is very thin and
can easily be stripped.
• Ne serrez pas trop la vis de
montage du connecteur HDMI. Le
blindage auquel elle est attachée
est très fin et peut facilement être
dénudé.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt
lacing bracket as shown (4).
5. While holding the connector securely against the lacing bracket, tighten the tie
wrap, then remove any excess length.
Connecting Output Displays
DHDMI outputs (see figure2 on page6) — Use an HDMI cable to connect up to
six output displays to the female HDMI ports on the rear panel .
NOTE: Secure the input and output connectors to the distribution amplifier with the
provided LockIt HDMI lacing bracket (see Securing the HDMI Connector).
By default, the EDID is set to 1080p@ 60Hz with 2‑channel audio. However, EDID can
be changed by using PCS (see EDIDMinder on page19). There are two, four, or six
slots that are automatically populated by EDID from connected sink devices.
The DA monitors the EDID of each connected display to ensure compatibility with the
input signal. The following adjustments are made for each output independently:
• Interface format —If the connected display is DVI and the input signal is HDMI,
the signal is reformatted to DVI. If the output is HDMI and the input is DVI, no
reformatting is needed because HDMI is backwards compatible with DVI.
• Video color bit depth —The signal can be forced to always truncate to
8‑bit, disabling deep color, via SIS commands (see Video Color Bit Depth on
page28) or PCS (see Output Configuration on page18).
• Audio —If the connected output device does not support the audio format of the
input signal, audio is muted.
If the source requires HDCP encryption and the display is not HDCP compliant, that
output channel outputs a green screen.
All outputs carry +5VDC and up to 250mA on pin18, regulated by a current limiting
circuit.

APower status LED — Lights when power is applied to the unit.
BUSB Config port — Used for SIS commands and PCS configuration, monitoring, and
firmware updates. This port can be used as an alternative to the rear panel RS‑232
captive screw connector (see Connecting to Front Panel USB Port on page12).
NOTE: Extron recommends using the USB port for temporary connections. If a
permanent connection is required, the RS‑232 port should be used.
CInput Signal LED — Lights when a TMDS signal is detected on the HDMI input. If the
source requires HDCP encryption, this LED may light only when HDCP is authenticated.
DOutput Signal LEDs — Light when hot plug detect is detected from the corresponding
sink device. Each output signal has its own signal LED: two for the DA2HD4KPLUS,
four for the DA4HD4KPLUS, and six for the DA6HD4KPLUS.
EInput HDCP LED — Lights when the source requires HDCP encryption and it has
been authenticated with the HDMI input.

FOutput HDCP LEDs (see figure4 on page11) — Light when HDCP is
authenticated between the distribution amplifier output and the corresponding sink
device. This happens when the source device requires HDCP encryption and it has
already been authenticated on the HDMI input.
• The LEDs do not light if the source does not require HDCP encryption or if the sink
is not HDCP compliant.
• Each output signal has its own HDCP LED: two for the DA2HD4KPLUS, four for
the DA4HD4KPLUS, and six for the DA6HD4KPLUS.
Connecting to Front Panel USB Port
Use the mini B USB port on the front panel (see figure5) to connect the distribution amplifier
to a host computer for updating firmware or to configure the unit with SIS Commands (see
page24) or Configuration Software (see page15).
Connect a USBA to miniB cable between the front panel USBConfigport and a USB port
of the PC.
