DL-AS61 Installation Guide
The DigitaLinx DL-AS61 is a compact multi-format switcher with support for video
resolutions up to UHD (3840x2160). With multiple built-in EDID settings, including
an EDID pass-through option, the highest quality digital video signal will be routed
directly to the display. When a VGA video signal is connected, the video signal will be
scaled up to 1920x1200.
The DL-AS61 supports stereo and multichannel audio on the HDMI inputs. The analog
audio paired with the VGA inputs is embedded into the digital video stream. In addition
to the audio embedded in the HDMI output stream, which may be muted, the audio is
simultaneously de-embedded to a digital optical audio output and two analog audio
outputs: 3.5mm TRS and 3-pin removable terminal block.
The DL-AS61 features multiple methods of control. When set to Auto, the switcher
will automatically switch to the newest source device added to the DL-AS61; when the
active source is removed, the DL-AS61 will switch to the lowest numbered input. The
DL-AS61 may be manually controlled by switching via the front panel, IR or RS232.

Automatic Switching:
When the DL-AS61 is in manual switching mode, the Auto Mode LED will be dark. To
change inputs, press either the previous or next button.
To enable automatic switching, press the Previous/Auto button for three seconds. The
Auto Mode LED will light.
When in auto-switch mode, the DL-AS61 will switch according to the following rules:
New Input: Upon detecting a new input, the switcher will automatically select the new
input.
Reboot: Once power is restored to the switcher, it will automatically reconnect the
input before powered off.
Source Removed: When an active source is removed, the DL-AS61 will switch to the first
available active input starting at HDMI Input 1.

VGA EDID
The EDID for the VGA inputs is permanently set to 1360x768. Other resolutions will
transmit properly through the DL-AS61. The built-in scaler will ensure consistent image
is present between analog and digital sources.

Important notice:
• Do not attempt to disassemble or alter the housing. There are no user-serviceable parts
inside the unit. Doing so will void your warranty.
• To minimize the possibility of equipment damage from electrostatic discharge (ESD), all

• Do not connect the device to a telecommunication outlet wired to unrelated equipment.
Doing so may damage the unit or any connected equipment. Ensure all connected twisted pair
cabling is straight-through (point-to-point).
• Allow proper ventilation to reduce the risk of thermal failure.
