Model Version Description Part #
 DSC 401 4K/60 HDMI to HDMI Scaler 60-1878-01
 DSC 401 A 4K/60 HDMI to HDMI Scaler w/ Audio 60-1878-02

The Extron DSC 401 and DSC 401 A are high-performance scalers capable of converting between HDMI resolutions up to 4K/60 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 signals on a single connection and provide many integrator-friendly features, such as on‑screen display, internal test patterns, and status LEDs. The DSC 401 A 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.

Advanced Vector 4K Scaling

Both scalers incorporate the Vector 4K scaling engine, developed in‑house and engineered to deliver best-in-class image upscaling and downscaling. Vector 4K embodies several Extron-patented scaling technologies, plus a new set of image processing algorithms that deliver uncompromising scaling performance. This enables sharp, accurate 4:4:4 processing and scaling of video signals up to 4K, as well as downscaling of 4K source signals for display in small windows or on lower-resolution displays without losing critical image detail.

High Performance Video Processing

The DSC 401 and DSC 401 A scalers provide high performance deinterlacing of all interlaced signals up to 1080i, and Deep Color processing to deliver optimal image quality. Automatic 3:2 and 2:2 pulldown detection maximizes image quality for source content originating from film. Additionally, the color space and chroma sampling of the HDMI output can be automatically set to ensure compatibility with a connected HDMI or DVI display.

Selectable FILL and FOLLOW modes are also available to support the proper aspect ratio of the output. FILL mode provides full screen output, while FOLLOW mode preserves the original aspect ratio of the input signal.

Professional Presentations

Signals sourced from an upstream switcher can be transitioned using cut through black, fade through black, seamless cut, or seamless fade for glitch-free, professional-looking presentations. For HDMI signals with protected content, Key Minder authenticates and maintains continuous HDCP encryption between input and output devices. The technology ensures the delivery of exceptional image quality with HDCP‑encrypted content.

Display Custom Images and Logos

The DSC 401 A scaler provides the convenience of uploading custom images, which can be displayed as a screen saver after a predefined duration of inactivity at the video input. This is also true whenever the input is disconnected between presentations. Additionally, a customized image can be displayed when HDCP‑encrypted content is transmitted to a non‑HDCP compliant display.

A custom graphic logo, such as a company logo, can be inserted into any presentation. Several key effects are available, and a logo can be positioned anywhere on‑screen.

Enhanced Audio Capabilities

The DSC 401 A includes a convenient 3.5 mm analog audio input for embedding audio onto the HDMI output, as well as a two‑channel analog audio output for sending de‑embedded audio to a sound system or other audio destination. It also delivers essential audio integration capabilities, including discrete, selectable analog and digital audio muting, analog input gain and attenuation, and output volume control.

Multiple Options for Control and Operation

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, and power signal status. On‑screen menus provide easy control of scaler functions and settings, including quick access to key parameters such as input and output video formats and resolutions. Remote configuration is available via USB on both models. The DSC 401 A can be configured or controlled externally over Ethernet.

Each scaler is housed in a 1", quarter-rack width metal enclosure and can be easily integrated into a variety of environments.
