The Extron IN1804 is a compact four input scaler that supports signal resolutions up to 4K/60 at 4:4:4. It incorporates Extron-patented Vector 4K scaling technology specifically engineered for critical 4K signal processing applications. It features DisplayPort and HDMI inputs with available models that provide Extron DTP2 extension of 4K/60 video, audio, and control signals up to 330 feet (100 meters) over a shielded CATx cable. The IN1804 delivers the convenience of fast and reliable automatic switching, along with advanced capabilities such as audio embedding/de-embedding, seamless transition effects, and logo keying. Designed for professional AV integration, the IN1804 can be controlled and configured using Ethernet, RS-232, USB, and contact closure with tally outputs.

Vector 4K Scaling

The IN1804 incorporates the Extron Vector 4K scaling technology, developed in‑house and engineered to deliver best-in-class image upscaling and downscaling. The Vector 4K engine embodies a new set of image processing algorithms that deliver uncompromising scaling performance with 30‑bit precision processing. This enables sharp, accurate scaling of standard definition and high definition signals up to 4K, as well as downscaling of 4K source signals for lower resolution displays without losing critical image detail.

For professional-quality transitions between sources, the IN1804 offers a range of switching effects. These include a freeze/fade transition that fades out a final frozen frame of the previous input source as the newly selected source fades in, a cut through black transition, and a fade through black transition. In addition, the IN1804 provides the capability to insert a custom graphic image, such as a company logo, onto the video outputs. Selectable FILL and FOLLOW modes are available to set the desired video aspect ratio. FILL mode provides full screen output, while FOLLOW mode preserves the original aspect ratio of the input signal.

Available Integrated Digital Twisted Pair Extension

The IN1804 DI and IN1804 DI/DO include one DTP2 twisted pair input to receive signals from remote DTP and DTP2 transmitters located at a conference table, lectern, or wall. The IN1804 DO and IN1804 DI/DO have one DTP2 output to transmit to a DTP or DTP2 receiver behind a flat-panel display on a wall, above a ceiling-mounted projector, or any other remote location. DTP transmitters and receivers are available in compact, low-profile enclosures, plus decorator-style wallplate and floorbox versions to suit the installation requirements of a specific application.

DTP2 connections include additional convenient, integrator-friendly features designed to help simplify installation. Bidirectional RS-232 and IR signals can be inserted from a control system and transmitted over the single shielded CATx cable together with the video and audio, enabling control of a source or display. Additionally, the IN1804 can send power to select DTP and DTP2 endpoints over the same shielded CATx cable, streamlining system design and installation. The DTP2 output on IN1804 DO and IN1804 DI/DO can be configured for compatibility with HDBaseT-enabled displays to send digital video and embedded audio, plus bidirectional RS‑232 and IR signals up to 330 feet (100 meters) over a shielded CATx cable.

In addition to supporting DTP endpoints, the IN1804 can be integrated into an XTP CrossPoint matrix switcher system. This is ideal for facility-wide AV system applications with a centralized AV signal distribution infrastructure, as well as several presentation spaces with local AV switching and processing. An IN1804 in a room can connect into an XTP CrossPoint matrix switcher in a central equipment rack or closet to receive shared AV resources, or a connected IN1804 can distribute a local presentation to several destinations in a facility.

Comprehensive EDID Management

To ensure professional AV systems perform as designed, it is crucial that EDID communication between video sources and sink devices is managed correctly. Correct management of EDID allows source equipment to send video and audio signals in formats and parameters that best match display device capabilities. Mishandling of EDID could result in suboptimal image quality, no image, and poor sound. The IN1804 offers a suite of Extron-exclusive tools and capabilities for complete control over EDID management. The EDID Minder software function offers a library of EDID files that can be applied to any video input. Additional EDID can be captured from connected displays or uploaded by the user. EDID Minder is easily accessible in PCS software, and EDID Manager 2.1 is a freely downloadable Windows utility for viewing and editing EDID files. This software enables video format optimization, chroma sampling and color bit depth manipulation, and adjustment to audio capabilities. Edited files may be saved, added to the library, and easily applied to devices within the system.

Multiple Options for Local and Remote Operation

The IN1804 features front panel controls and on-screen menus for quick access to system settings. It also features automatic switching between inputs to streamline system operation when the unit is installed in locations such as a lectern or under a conference table. Remote configuration and control are available via Ethernet, USB and RS‑232, plus contact closure with tally output for input switching and muting. The IN1804 can be configured using Extron's PCS software with a user‑friendly GUI that is very easy to navigate. This software application allows for expedited setup and commissioning, real-time operation and monitoring, plus the ability to configure multiple Extron products units in the same session.

Convenient Under-Table and Surface Mounting

The IN1804 is housed in a compact 1U, half rack width enclosure that can be installed virtually anywhere, including inconspicuous placement underneath a conference table, inside a credenza, or in a lectern. Extron UTS Series and MBU 123 mounting hardware are available separately to facilitate under‑table and surface mounting.
