AMX SDX-514M-DX – Precis 5x1 SDVoE DXLink Switcher with Multi-Window

Product Overview

The AMX SDX-514M-DX is a 5-input, 1+1 output 4K presentation switcher with integrated SDVoE-based multi-window compositing and DXLink twisted pair output, designed for conference rooms and collaboration spaces requiring flexible source routing, multi-window display capabilities, and distance transport over Cat cable. Accepting 3 HDMI and 2 HD-15 (RGBHV) inputs with 4K resolution support, the SDX-514M-DX delivers switched output to an HDMI and mirrored DXLink output with full AV and control transport, and supports MyTurn source selection for wireless-style HDMI/VGA cable-based switching without an external control system.

Product Description

The AMX SDX-514M-DX (FG1010-355) provides 5x1 dual audio/video switching, routing any of 5 inputs simultaneously to both the HDMI and DXLink outputs. Three HDMI inputs support HDMI/HDCP, and two HD-15 inputs accept RGBHV analog sources, supporting 4K resolutions up to 3840×2160 @ 60 Hz (4:2:0) and 4096×2160 @ 60 Hz (4:2:0). Multi-format audio includes Dolby TrueHD, DTS-HD MA, Dolby Digital, DTS, and 2–8 CH L-PCM from HDMI connections. The DXLink output transports digital video, audio, Ethernet, and bidirectional control over Cat cable to compatible DX-RX-4K receivers or Enova DGX DXLink input boards. An AxLink Keypad port supports up to 2 external AxLink keypads for room control. MyTurn source selection allows HDMI/VGA cable-connected source devices to trigger switching via MyTurn Source Selector Buttons and Receiver, or through HydraPort 2-Button Keypad modules. Three RJ-45 Ethernet connections provide TCP/IP management and integration with AMX control systems.

Frequently Asked Questions

Does the SDX-514M-DX require an AMX controller for source switching?

No — the SDX-514M-DX supports MyTurn source selection via cable-mounted buttons and receiver for controller-free switching. An AMX control system can be added for automation, but is not required for basic room operation.

What receiver is used with the DXLink output?

The DXLink output is compatible with the AMX DX-RX-4K DXLink 4K HDMI Receiver as a point-to-point solution, or with Enova DGX DXLink 4K input boards (DGX-I-DXL-4K) for matrix-based installations.

What is the maximum 4K resolution supported?

The SDX-514M-DX supports 4K at 60 Hz with 4:2:0 chroma subsampling (3840×2160 or 4096×2160 @ 60 Hz), and 4K at 24/25/30 Hz with full 4:4:4. For 4K60 at 4:4:4, specify the DXFP or newer generation products.
