About this Guide
The DSC 401 and DSC 401 A User Guide describes the Extron DSC HDMI-to-HDMI Digital
Scaling Converters and provides instructions for experienced installers to install, configure,
and operate them.
In this guide, the terms “scaler” and “DSC” are used interchangeably to refer to either of the
DSC 401 and 401 A models.
About the DSC 401 and DSC 401 A
The Extron DSC 401 and DSC 401 A are high-performance scalers capable of converting
between HDMI resolutions up to 4K @ 60 Hz with full 4:4:4 color sampling. They
support data rates up to 18 Gbps and incorporate the Extron-exclusive Vector™ 4K
scaling technology, which is engineered for critical-quality 4K applications. Both HDCP
2.3-compliant models support 4K @ 60 Hz signals on a single connection.
The scalers feature on-screen displays, internal test patterns, and status LEDs. The
DSC 401 A model also features audio embedding and de-embedding, logo image keying
and display, input presets, audio file playback, and Ethernet control with PoE. The DSC 401
and DSC 401 A scalers are ideal for locations such as conference rooms, auditoriums, or
anywhere high-quality 4K scaling of HDMI signals is required.
Both scalers feature front panel controls for quick access to functions. Additionally, LED
indicators on the front panel provide visual confirmation of video input signals, the presence
of HDCP encryption, reset levels, and power. Remote configuration is available via USB-C
on both models. The DSC 401 A can be configured or controlled externally over Ethernet.
Each scaler is housed in a compact, 1-inch, quarter-rack wide metal enclosure.
DSC 401 and DSC 401 A User Guide • Introduction 1

Features
• 4K @ 60 Hz HDMI to HDMI scaling — The DSC 401 and DSC 401 A scalers provide
high quality scaling of HDMI video resolutions and frame rates.
• Connectors —
• Input — One female HDMI Type A
• Audio Input (DSC 401 A only) — One 3.5 mm stereo mini jack
• Output — One female HDMI Type A
• Audio Output (DSC 401 A only) — One balanced and unbalanced stereo audio
on 5-pole captive screw
• Advanced Extron Vector 4K scaling engine — The Vector 4K scaling engine is
specifically designed for critical-quality 4K imagery, with best-in-class image upscaling
and downscaling.
• HDCP 2.3 compliant — Ensures display of content-protected media and
interoperability with other HDCP-compliant devices.
• Advanced 4:4:4 signal processing — 4:4:4 signal processing maintains color
accuracy and fine picture detail.
• Input resolutions — Accepts HDMI video from 480i up to 4096x2160 @ 4:4:4.
• Selectable output rates from 640x480 up to 4096x2160 @ 4:4:4.
• Supported HDMI specification features include data rates up to 18 Gbps, Deep
Color, and HD lossless audio formats
• Motion-adaptive deinterlacing — Advanced deinterlacing for all interlaced signals up
to 1080i delivers optimized image quality.
• Seamless transitions — Automatically applies a seamless fade or cut when a new
source is detected.
• Automatic 3:2 and 2:2 pulldown detection — Advanced film mode processing
techniques instantaneously detect and maximize image quality for NTSC, PAL, and
1080i sources that originated from film.
• User-selectable HDCP authorization — Allows the unit 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.
• EDID Minder — EDID Minder ensures that the source powers up properly and reliably
outputs content for display. It manages EDID communication between connected
devices.
• Custom EDID and output resolutions — User-defined output resolutions up to
600 MHz pixel clock can be supported by uploading custom EDID files or capturing
EDID from a display or other destination device.
• Aspect ratio control — The aspect ratio of the video output can be controlled by
selecting a FILL mode, which provides a full-screen output, or a FOLLOW mode, which
preserves the original aspect ratio of the input signal.
• Scaler Bypass Mode — Allows scaling to be bypassed to support unprocessed
transmission of 3D, HDR, and other formats.
• HDCP authentication and signal presence confirmation — Provides real-time
verification of HDCP status for each digital video input and output. This allows for quick
and easy signal and HDCP verification through USB or Ethernet, providing feedback to
a system operator or helpdesk support staff.
