About this Guide

This guide describes the SW HD 4K Series switchers and discusses how to install,
configure, and operate them.

In this guide, the terms “SW HD 4K Series” and “SW HD 4K” refer to the SW2 HD 4K,
SW4 HD 4K, SW6 HD 4K, and SW8 HD 4K switchers.

About the SW HD 4K Series Switchers

The SW HD 4K Series are two, four, six, and eight input HDMI switchers for 4K video
signals. They switch 4K signals from multiple HDMI source devices to a single display.
The switchers support computer and video resolutions up to 4K and 1080p/60 with Deep
Color, as well as data rates up to 10.2 Gbps, 3D, Lip Sync, and HD lossless audio formats.
All models feature EDID Minder, which maintains continuous EDID communication with
connected devices and ensures that the HDMI sources power up properly and maintain
correct video output. The switchers provide automatic input cable equalization up to
50 feet (15 meters) on Extron HDMI Pro Series cable. The SW HD 4K Switchers can be
controlled via the front panel, RS-232 interface, USB, contact closure, auto-input and
can be integrated into various environments. You can select inputs by pressing the front
panel buttons and IR 102, enabling auto-input switching, attaching a jumper or a contact
closure device to the Contact port, or entering Simple Instruction Set (SIS) commands via
RS-232 or USB.

compensate for signal loss when using long HDMI cables, low quality HDMI cables, and
source devices with poor HDMI signal output.

SW HD 4K Series • Introduction 1

• HDCP compliant — Ensures display of content-protected media and interoperability

with other HDCP-compliant devices.

• User‑selectable HDCP authorization — Allows individual inputs to appear HDCP

compliant or non-HDCP compliant to the connected source, which is beneficial if the
source automatically encrypts all content when connected to an HDCPcompliant
device. Protected material is not passed in non-HDCP mode.

• HDCP authentication and signal presence LED indicators

• Automatic color bit depth management — The switcher automatically adjusts color

bit depth based on the display EDID, preventing color compatibility conflicts between
source and display.

• Provides +5 VDC, 250 mA power on the output for external peripheral devices

• Easy setup and commissioning with the Extron Product Configuration Software

— Conveniently configure multiple products using a single software application.

• Multiple control options including front panel, RS‑232, USB, IR, contact closure,

and auto‑input switching

• Contact closure remote control with tally output — Allows for remote selection of

an input channel. +5 VDC is provided to light an LED to indicate the currently selected
input.

• Power supply —

• SW2 and SW4 HDMI: An energy-efficient, external 12 VDC, 1 A universal power

supply with a 2-pole captive screw connector accepts 100 to 240 VAC.

• SW6 and SW8 HDMI: An 50-60 Hz, internal universal power supply with a

standard IEC connector accepts 100 to 240 VAC.

• Includes LockIt HDMI cable lacing brackets

• Rack and Furniture Mounting — The SW HD 4K switchers can be mounted on a

rack shelf or under a desk or podium with an optional mounting kit.
