IN1606 and IN1608 Series Scaling Presentation Switcher • Introduction 5
Key Features
Video
• Four HDMI inputs and two configurable analog video inputs — Allow for
switching between HDMI and analog video sources. Two configurable analog inputs
accept most standard analog video formats, including RGB, component video,
RGBcvS, S-video, and composite video signals.
• HDMI, HDTV, RGB, and video source integration into presentation systems with
audio switching — Provides centralized switching for a wide range of AV sources.
• Interface format correction — Automatically reformats HDMI source signals for
output to a connected DVI display.
• Glitch-free switching — Enhances presentations by eliminating distractions during
switching with glitch-free cut through black and fade through black transition effects.
• Two simultaneous HDMI outputs — Drives two displays.
• Selectable output rates — Includes computer-video output rates from 640x480 to
1920x1200, HDTV rates up to 1080p/60, and 2048x1080.
• Integrated DTP 230 inputs and output (IN1608 models only)— Support digital
signal transmission of HDMI or DVI plus control and analog audio up to 230 feet
(70 meters) over a single CATx cable, providing high reliability and maximum
performance on an easily installed cable infrastructure.
Audio
• Front panel output volume control — Provides volume control for the variable,
program, or mic audio output. Both fixed and variable line level outputs are available,
and each output can be balanced or unbalanced. Stereo input signals can be output as
dual mono.
• Two mic/line inputs with ducking and 48 volt phantom power — Independently
mixes microphone channels with program audio, which is embedded onto the HDMI
outputs. Selectable 48 volt phantom power allows the use of condenser microphones.
• Audio input gain and attenuation — Gain or attenuation can be adjusted for each
analog input to eliminate noticeable differences when switching between sources.
• Advanced audio configuration — Offers complete control of audio input and output
gain, attenuation, mixing, and ducking parameters via internal Web pages.
• Audio breakaway — Provides the capability to break an analog audio signal away
from its corresponding video signal and route to the audio outputs.
• 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 and de-embedding — Embeds analog audio signals
onto the HDMI output signals or extracts embedded HDMI LPCM audio to the analog
outputs, or passes bitstream formats.
• Available with energy efficient Class D stereo or mono amplifier —
The IN1608 SA offers a stereo power amplifier with 50 watts per channel into 4 ohms
and 25 watts per channel into 8 ohms, while the IN1608 MA offers a mono 70 volt
power amplifier with 100 watts rms output. Both feature an Extron patented, highly
efficient, advanced Class D amplifier design with CDRS - Class D Ripple Suppression,
that provides a smooth, clean audio waveform and an improvement in signal fidelity over
conventional Class D amplifier designs. CDRS eliminates the high frequency switching
ripple characteristic of Class D amplifiers.
