Introduction
Overview
The ALF-MUK44N is a 4x4 compact HDMI matrix switcher, specially
designed for cost conscious projects and buyers. It features not only basic
functions like cross-point switching and control (IR, RS-232 and IP), but also
advanced functions such as auto-downscaling for each HDMI output when it
is connected to 1080P display. There is a SPDIF audio breakout for each
HDMI output, to provide more audio feeds to multi-zone audio system.
Features
4 HDMI Inputs and 4 HDMI Outputs.
All HDMI inputs and outputs support HDMI with HDR formats, including
HDR 10, HLG, DOLBY VISION up to 4K@60 4:4:4.
HDCP2.2 compliant.
With built-in 4K-1080P downscaling for each HDMI Output, the matrix
can downscale 4K@60Hz 4:4:4 to 1080P@60 4:4:4. 4K downscaling
works automatically when the matrix is connected to a 1080P display
and can be set to ON/OFF by API commands.
Each HDMI output has a SPDIF audio breakout and supports formats up
to 5CH HBR (High Bit Rate) or 2CH PCM audio.
Supports smart EDID; each input can be assigned to smart EDID mode.
Supports EDID presets, EDID copy and EDID write. By default, each
input EDID is set as 4K@60 4:4:4 HDR with 5.1CH encoded audio.
Supports audio mute as the four SPDIF outputs can be muted separately
by API commands.
