Audio; General - Extron electronics IN1604 DT User Manual

Integrated DTP output (IN1604 DTP only) — Supports digital signal transmission of
•
HDMI or DVI plus control and analog audio up to 330 feet (100 meters) over a single
shielded twisted pair cable, providing high reliability and maximum performance on an
easily installed cable infrastructure.
• HDMI output (IN1604 HD only) — Provides one HDMI output.

Audio

• One stereo balanced/unbalanced audio input on captive screw and one
unbalanced stereo audio input on a 3.5 mm stereo mini jack — Allows flexible
audio switching with two individually assignable analog audio inputs.
• Audio input gain and attenuation — Gain or attenuation can be adjusted for each
analog input to eliminate noticeable differences when switching between sources.
• Audio input assignment — Enables all four video inputs to share a single analog
audio input. Each video input can be assigned to either of the two available analog
audio inputs.
• Audio switching transition — Lowers the audio of the switched-out source while
simultaneously bringing up the audio of the activated source. The duration of the audio
crossfade matches the duration of the video switching transition.
• Automatic integrated audio delay — Compensates for latency introduced by the
video processing.
• HDMI audio embedding — Embeds analog audio signals onto the DTP or HDMI
output.
HDMI audio de-embedding — Extracts embedded HDMI two-channel PCM audio to
•
the analog output, or multi-channel bitstream formats that can be passed to the output.
• Output volume control — Provides master volume control for the audio output.
Selectable audio muting — Individually or simultaneously mutes the analog and
•
embedded digital audio outputs.

General

• Supported HDMI specification features — Includes data rates up to 6.75 Gbps,
Deep Color, and HD lossless audio formats.
HDCP-compliance — Fully supports HDCP-encrypted sources, with selectable
•
authorization for unencrypted content.
• HDCP authentication and signal presence confirmation — Provides real-time
verification of HDCP status for each digital video input and output. This allows for quick
signal and HDCP verification through RS-232, USB, or front panel LED indicators,
providing feedback to a system operator or helpdesk support staff.
• HDCP Visual Confirmation — Sends a full-screen green signal 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.
• Bidirectional RS-232 and IR insertion for AV device control (IN1604 DTP only)
— Transmits RS-232 control and IR signals alongside the video signal over DTP
connection, allowing the remote device to be controlled without the need for additional
cabling. Bidirectional control extension eliminates the need for control system wiring to
remote devices.
• Support for integrated DTP output (IN1604 DTP only) — Supports transmission
of HDMI, control, and analog audio up to 330 feet (100 meters) over a shielded twisted
IN1604 DTP and IN1604 HD Scalers • Introduction 3
