Introduction
This guide describes the function, installation, and operation of the HDMI DA4 and HDMIDA6.
Unless otherwise stated, the terms “distribution amplifier” or “DA” refer to either of these
distribution amplifiers.
This section provides the following information:

These Extron distribution amplifiers distribute one HDMIinput signal to four (HDMI DA4) or
six (HDMI DA6) simultaneous outputs. Both models are fully High‑bandwidth Digital Content
Protection (HDCP) compliant.
These distribution amplifiers support data rates up to 6.75 Gbps (2.25 Gbps per color) with up
to 12‑bit deep color and use the EDID Minder®feature for EDID management.
The automatic output compatibility correction feature scans each output device to ensure that
the output signal is compatible with the color depth and format requirements of the device.
Each output is adjusted independently.

HDMI signal distribution — These distribution amplifiers accept one HDMI input and provide
four (HDMI DA4) or six (HDMI DA6) simultaneous HDMI video and embedded multi‑channel
digital audio signal outputs. Supported HDMI specification features include data rates up to
6.75 Gbps, Deep Color up to 12‑bit, 3D, Lip Sync, and HD lossless audio formats.
Supports high-resolution video — including computer‑video to 1920x1200, iHDTV
1080p/60 and 2K.
HDCP compliant
Key Minder — continuously verifies HDCP compliance. Key Minder authenticates and
maintains continuous HDCP encryption between all input and output devices to enable
simultaneous distribution of a single source signal to multiple displays.
EDID Minder — This feature allows the user to choose from a list of 48factory‑loaded EDID
files, to import EDID information from either of the display devices, or to import and save
an EDID file from a PC. EDID Minder has two modes of operation that can be selected and
configured using SIS commands:
zAutomatic: EDID from the display connected to output 1 is read and stored at the input
automatically (default mode). Use SIS commands to read and store EDID from other
outputs.
zUser assigned: EDID can be manually assigned from the internal factory EDID table,
which contains 48 unique EDID files categorized by native resolution and audio support.
Additionally, there are four user slots available to store and recall EDID from connected
displays.
HDMIDA4andHDMIDA6•Introduction 1

Automatic input cable equalization — to 50 feet at 1080p/60 with 8‑bit color when used
with Extron HDMI Pro Series cable. Actively conditions incoming HDMI signals to compensate
for signal loss when using long cables, low quality cables, or source devices with poor signal
output.
Output Compatibility Correction — The distribution amplifiers monitor the EDID of each
connected display to ensure it is compatible with the current input signal. The following
adjustments are made for each output independently:
zInterface 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.
zVideo color bit depth: If the connected output device does not support the color
bit depth of the input signal, it is truncated down to the next level that is supported
(12‑bit>10‑bit > 8‑bit). The signal can be forced to always truncate to 8‑bit via Simple
Instruction Set (SIS) commands, disabling deep color.
Output muting via RS-232 — Provides the capability to mute one or all outputs at any
time. This allows content to be viewed on a local monitor prior to appearing on the main
presentation display.
Signal Status LEDs for the input and each output — LED indicators for signal presence
and HDCP authentication provide real‑time feedback and monitoring of key performance
parameters. The bi‑color EDID LED indicator notifies whether an internal or external EDID is
stored.
Easy mounting options — The HDMI DA4 and HDMI DA6 are a half rack wide, 1 U high, and
6 inches deep. They can be conveniently mounted in standard racks or under furniture.

To install and set up the HDMI DA4 or HDMI DA6, follow these instructions:
1. Mount the Distribution Amplifier in a suitable location (see page 14).
2. Connect to a 100-240 VAC (50 or 60 Hz) power source using the provided IEC power
cord (see page 4).
3. Connect the display devices and power them on (see page5).
The distribution amplifier automatically reads and stores EDID from the selected display
device. By default, this is the device connected to output 1. For other EDID options, see
EDID Minder on page 11.
4. If configuration using SIS commands is required (see page 15), connect a control PC
to the rear panel captive screw connector (see page6) or the front panel USB port
(see page 7).
5. Connect and power on the input device (see page 5).

RS‑232 communication between the distibution amplifier and a host PC can be used to
update firmware or configure the unit using SIS commands (see “Command and Response
Table for SIS Commands“ on page 17).
The computer connects to either the rear panel 3‑pole RS‑232 port (din figure 2 on page 3)
or the front panel USB port (bin figure 7 on page 9) of the distribution amplifier.

 Neither port has precedence and commands from either port are handled in the
order they are received.
 Extron recommends that the USB port is used for temporary connections. If a
permanent connection is required, the RS‑232 port should be used.
1. Connect an RS‑232 cable, such as Extron universal control cable (UC 50' or UC100') to
the computer, using a female 9‑pin D connector (see figure 3):
zData received by the computer = pin 2
zData transmitted by the computer = pin 3
zGround = pin 5
2. Wire the opposite end of the cable to the provided 3‑pole captive screw plug (see
figure3):
zData transmitted by the DA plugs into the Tx (transmit) port
zData received by the DA plugs into the Rx (receive) port
zGround plugs into the G (ground) port

 The wiring in the RS‑232 cables crosses over so that the Tx on the distribution
amplifier connects to the Rx of the control device and vice versa. Ground always
connects to ground.

EDID Minder ensures that the connected source sees the EDID of a display, even if a display
is not connected. Depending on the EDID mode selected (by SIS command), the EDID of a
connected display can be stored automatically, or the user can manually select from the table
of factory loaded EDID files. This EDID is stored on an EEPROM located at the HDMI input.
By default, the HDMI DA4 and HDMI DA6 are configured to store EDID from the display
connected to output 1 automatically. The unit reverts to this configuration after a factory reset.

In automatic mode, the HDMI DA4 or HDMI DA6 automatically read and store EDID from
output 1 (a different output can be chosen using SIS commands). This EDID is retained until a
different display is connected to output 1 or the unit is power‑cycled. If no display is connected
to output 1 when the unit is powered on, then the factory default EDID (720p @ 60 Hz, 2‑Ch
audio) is used.

In user assigned mode, the user can select from 48 factory loaded EDID files, each
catagorized by rate type (PC or HDTV), video format (DVI or HDMI), audio type (2‑Ch or Multi‑
Ch), and native resolution. The unit retains this setting after a power cycle.
Additionally, four user‑loaded slots are available to save the EDID of any connected display.
EDIDs saved to these slots are retained after a power cycle. Upon a factory reset, these EDIDs
revert to the factory default (720p @ 60 Hz, 2‑Ch audio).
A table showing the factory loaded EDID options is shown on the following page. The EDID
memory location is labelled X% for consistency with the value in the SIS commands.

The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of
these products in a rack:
1. Elevated operating ambient temperature — If the unit is installed in a closed or
multi‑unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient temperature. Therefore, install the equipment in an
environment compatible with the maximum ambient temperature (Tma: +122 °F, +50°C)
specified by Extron.
2. Reduced air flow — Install the equipment in the rack so that the equipment gets
adequate air flow for safe operation.
3. Mechanical loading — Mount the equipment in the rack so that uneven mechanical
loading does not create a hazardous condition.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Consider the equipment nameplate ratings when addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack‑mounted
equipment. Pay particular attention to supply connections other than direct connections to
the branch circuit (such as the use of power strips).
