Extron DTP HD DA 4K Series • Introduction 2
• HDMI input loop‑through — The DTP HD DA 4K series features an active local HDMI
output for local monitor support or system expansion.
• Audio input with loop‑through accepts additional analog stereo audio
signals— The DTP HD DA 4K series accepts stereo analog audio signals for
simultaneous transmission over the same shielded twisted pair cable, and it includes
a loop-through for local audio system and monitoring needs. Analog audio is not
embedded onto the digital video signal, nor is digital audio de-embedded from the
digital video signal.
• Supports multiple embedded audio formats — The DTP HD DA 4K series is
compatible with a broad range of multi-channel audio signals, providing reliable
operation with HDMI sources.
• Remote powering of DTP receivers — The DTP HD DA 4K series can provide power
to four or eight DTP receivers over the twisted pair connections, eliminating the need for
separate power supplies at the remote units.
• RS‑232 insertion from the Ethernet control port — System level AV device control
to all remote locations via the Ethernet port on the distribution amplifier, providing
control of the attached devices without needing additional equipment.
• Bidirectional RS‑232 and IR pass‑through for AV device control — Bidirectional
RS-232 control and IR signals can be transmitted alongside the video signal, allowing
remote AV devices to be controlled without the need for additional cabling.
• HDCP compliant
• Supported HDMI specification features include data rates up to 10.2 Gbps,
Deep Color up to 12‑bit, 3D, and HD lossless audio formats
• Key Minder continuously verifies HDCP compliance — Key Minder authenticates
and maintains continuous HDCP encryption between input and output devices to
enable simultaneous distribution of a single source signal to two or more displays.
• EDID Minder automatically manages EDID communication between connected
devices — EDID Minder ensures that the source powers up properly and reliably
outputs content for display.
• Supports EDID and HDCP transmission — DDC channels are actively buffered,
allowing continuous communication between source and display.
• HDCP authentication and signal presence confirmation — Provides real-time
verification of HDCP status for each digital video input and output.
• HDCP Visual Confirmation provides a green signal when encrypted content
is sent to a non‑compliant display — A full-screen green signal is sent when
HDCP-encrypted content is transmitted to a non-HDCP compliant display, providing
immediate visual confirmation that protected content cannot be viewed on the display.
• HDMI to DVI Interface Format Correction — Automatically enables or disables
embedded audio and InfoFrames, and sets the correct color space for proper
connection to HDMI and DVI displays.
• RS‑232 control port — Enables the use of serial commands for integration into
a control system. Extron products use the SIS - Simple Instruction Set command
protocol, a set of basic ASCII commands that allow for quick and easy programming.
• RJ‑45 signal and link LED indicators for DTP ports — Provides a means for
validating signal flow and operation.
• Compatible with all DTP 230 and DTP 330 Series receivers and DTP‑enabled
products — Enables mixing and matching with desktop and wallplate receivers, as well
as other DTP-enabled products to meet application requirements.
