SW-42Plus User Manual
1Introduction
The SW-42Plus is an HDMI 2.0 Audio/Video 4x2 Matrix Switch. The device has four HDMI inputs, two
HDMI outputs, two SPDIF outputs, and two Analog Audio Left/Right Balanced/Unbalanced outputs. Each
HDMI video output can be connected to any HDMI video input. Audio outputs 1 and 2 mirror the
embedded audio of HDMI outputs 1 and 2.
Both HDMI outputs have automatic down scalers for mixed resolution display environments. For
example, HDMI output #1 is connected to a native UHD display and HDMI output #2 is connected to a
1080p Display. If both outputs select the same source input with UHD resolution, then output #1 will
send the native UHD resolution video to the UHD display while output #2 will automatically downscale
the video for the 1080p display. This ensures compatibility by displaying the same source with different
resolution displays, while maintaining the highest quality native resolution for the UHD display.
Audio can be extracted from the connected HDMI inputs or from Audio Return Channel (ARC) on HDMI
Output #2. Table 1 shows where the extracted audio can be heard. Extracted ARC from HDMI output
#1 can be directed to HDMI input #1 if an ARC enabled Audio/Video Receiver (AVR) is connected to HDMI
input #1. Refer to Figure 3: Typical Interconnect Diagram. ARC can also be decoded and re-embedded
to HDMI Output #2, SPDIF Outputs, or Analog Audio Outputs (2-channels only).
Table 1: Audio Source to Audio Output support.
Source of Extracted Audio

HDMI Input
•Analog Audio Output 1 or 2 (2-Channel PCM Stereo Only)
•TOSLINK 1 or 2 (Multi-Channel Dolby/DTS Surround Sound)

•Analog Audio Output 1 or 2 (2-Channel PCM Stereo Only)
•TOSLINK 1 or 2 (Multi-Channel Dolby/DTS Surround Sound)
•HDMI Input 1 (Multi-Channel Dolby/DTS Surround Sound)
•HDMI Output 2
The SW-42Plus can negotiate with a Smart TV connected to HDMI Output #1 to enable ARC audio even
if there is no ARC supported AVR or a SoundBar connected in the system. This extracted ARC can be
directed to the SPDIF outputs, Analog Audio Outputs, and HDMI Output #2.
The SW-42Plus includes an IR Remote Control for configuring the video matrix connections between
inputs and outputs. The unit can also be controlled by 3rd party Control Systems (appropriate drivers
required) through control ports such as IR Port (3.5mm Jack), RS-232 (DB9), and Ethernet LAN.
The SW-42Plus is featured with a webGUI interface called ZigNet. With ZigNet, the user has full control
of Audio/Video Switching, Analog Audio Processing, Source and Sink Diagnostics, and EDID Reporting.
ZigNet eliminates the need for costly analyzers and time-consuming step by step troubleshooting.

IR Sensor
This IR sensor receives signals from the included IR Remote Control unit. Aim the IR Remote Control in
this window while pressing its buttons.
HDMI Input Selection Buttons
These illuminated buttons are used to select which of the four HDMI Inputs are to be routed to the HDMI
Outputs. Both video and embedded audio will be routed. If the buttons are illuminated blue, then
Output #1 will be connected to the selected HDMI Input. If the buttons are illuminated red, then Output
#2 will be connected to the selected HDMI Input. The selected HDMI input button will illuminate while
all other input buttons will be off. Flashing LED behaviors may occur for alert and diagnostic purposes.
Output Button
The Output button selects which of the two HDMI Outputs will be configured. Pressing the Output
button will toggle its illumination between blue and red. If the Output button is illuminated blue, then
HDMI Output #1 will be connected to the selected HDMI input. Conversely, red illumination will
configure HDMI Output #2 to the selected HDMI input.
Power Button
Pressing this illuminated button will toggle between Active Mode (Blue) and low power Stand-By Mode
(Red) when power is applied from the included 12V DC power supply connected to an electrical outlet.
In Stand-By Mode, no video will be present at the output and the audio will be muted. However,
administration through Ethernet and RS-232 ports will still be active to wake up the SW-42Plus.

3Rear Panel
HDMI Inputs
Connect the video sources to any of the four HDMI inputs, which corresponds to the HDMI Input
Selection buttons 1-4 located in the front panel. Input #1 supports Audio Return Channel (ARC), and by
default, should be connected to an ARC capable AVR or Soundbar.
Note: Zigen highly recommends the use of premium 4K certified HDMI cables when viewing UHD 60p
4:4:4 or UHD 60p HDR 4:2:2 video resolutions. Zigen offers these premium 4K certified cables in varying
lengths from 3 meters to 9 meters.
HDMI Output
Connect displays to the HDMI Outputs. One of the selected inputs will route video and embedded audio
to this output. ARC is supported on HDMI Output #1. If ARC is enabled from a SmartTV, then the ARC
audio sourced by the SmartTV will be redirected to HDMI input #1 if an ARC capable Audio/Video
Receiver (AVR) or Soundbar is connected (refer to Figure 3: Typical Interconnect Diagram).
ARC can be extracted from HDMI Output 1 even if an ARC supported AVR or SoundBar is not
implemented in the system. In this case, the SW-42Plus becomes an Audio System to negotiate with the
Smart TV to enable its ARC. This extracted ARC audio can be routed to the SW-42Plus audio outputs,
even embedding the audio to HDMI Output 2. This is useful to allow audio sourced from SmartTVs to be
sent to legacy AVRs (connected to Output #2), or any other sink devices, that do not support ARC.
SPDIF (TOSLINK) Output
The SPDIF (TOSLINK) optical ports will output the embedded audio from either the selected HDMI Inputs
or from HDMI Output #1 ARC depending on the audio source selection on the ZigNet Web Interface. The
SPDIF outputs supports 2-Channel PCM as well as surround sound formats like DOLBY Digital and DTS.
If HDMI Inputs are the source of the audio, then SPDIF optical port #1 mirrors the embedded audio of
HDMI Output #1. Moreover, SPDIF optical port #2 mirrors the embedded audio of HDMI Output #2.
Balanced/Unbalanced Analog Audio Outputs
The Analog Audio Left/Right connectors will output analog audio from either the selected HDMI Inputs
or from HDMI Output #1 ARC depending on the audio source selection on the ZigNet Web Interface.
Only 2-Channel Stereo audio format is supported. Noise may be heard on the Analog Audio Outputs if
audio EDID is configured for surround sound formats, such as 5.1, 7.1, Dolby Digital, DTS, etc.

Video
1. Use HDMI cables to connect UltraHD sources to the Inputs on the back panel of the unit.
2. Use an HDMI cable to connect a display to the Output on the back panel of the unit.
The HDMI cable can then be connected in any of the following ways:
•Connect the HDMI cable to an Ultra HD display.
•Connect the HDMI cable to another Zigen switch or splitter, for cascading purposes.
Note: Zigen highly recommends the use of premium 4K certified HDMI cables when
viewing UHD 60p 4:4:4 or UHD 60p HDR 4:2:2 video resolutions. Zigen offers these
premium 4K certified cables in varying lengths from 3 meters to 9 meters.
Audio
1. Determine desired Audio output type: Balanced or Unbalanced.
Wire the appropriate Audio connectors to the included Phoenix plug in accordance with the diagram on
Figure 1: Balanced (Professional-Level) Audio Pin Out or Figure 2: Unbalanced (Line-Level) Audio
Output Pin Out.
2. Connect the Audio connectors to appropriate Multi-Zone Amplifiers, AVRs, and/or Mixers.
3. On ZigNet, configure Audio Output Type parameter, Balanced or Unbalanced, and ensure the
selection matches the wiring of the Analog Audio Ouput Phoenix connectors.
Important: Ensure the SW-42Plus audio settings in the ZigNet Web Interface match the
audio interface (Balanced or Unbalanced) wiring. Failure to do so may result in extremely
high volume and possibly causing damage to speakers or other equipment.
Power
1. Connect the included 12VDC@2A locking power supply to the 12V DC power receptacle on the
rear panel of the switch.
2. Connect the power supply to an electrical outlet.
IMPORTANT: Ensure that all video, audio, and control port interconnects are properly
connected before applying power to the unit. Failure to do so could cause irreparable
damage to the unit or cause injury to installers and end-users.

9ARC Support
Audio Return Channel (ARC) is a feature where a display can send audio back to an Audio/Video Receiver
(AVR) or Soundbar using the display’s existing HDMI cable. Any HDMI cable can be used to transmit ARC
and no additional audio cables, such as TOSLINK or RCA, are required. Audio to be sent through the ARC
channel can be sourced from the display’s numerous HDMI Inputs or, in the case of a SmartTV, built-in
Apps such as Netflix®, or YouTube®.
There are two ways to connect the SW-42Plus to make the unit work with ARC. In both methods, a
SmartTV is the ARC source and is connected to the SW-42Plus Output #1. Figure 3 shows a typical
interconnect where an ARC featured AVR is connected to HDMI Input #1. In this method, the SW-42Plus
becomes a passive device and directly passes all CEC and ARC traffic from HDMI Output #1 to HDMI Input
#1. ARC negotiation and CEC control are performed directly between the Smart TV and the AVR. The
SW-42Plus can intercept the ARC audio and redirect it to the unit’s audio output interfaces. The SW-
42Plus can decode ARC and re-embed this audio to HDMI Output 2. This is useful to allow ARC featured
SmartTVs to output its audio stream to multi-zone amplifiers or legacy AVRs without ARC support. ARC
redirection to audio output interfaces is enabled using the ZigNet interface.
Figure 4 shows an interconnect where no ARC featured AVRs or SoundBars are implemented in the
system. In this second method, the SW-42Plus becomes an Audio System and will negotiate with the
SmartTV to enable its ARC. The SW-42Plus will extract the ARC audio and can redirect it to the unit’s
audio output interfaces as well as HDMI Output #2. ARC redirectionto audio output interfaces is enabled
using the ZigNet interface.
