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,

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.
