IN1606 and IN1608 Series Scaling Presentation Switcher • Introduction 7
Key Features
Video Features
• Multiple input types — Allow for switching between HDMI and analog video sources.
Two configurable analog inputs accept most standard analog video formats, including
RGB, HD component video, 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.
• Simultaneous video outputs — Drives two or three displays depending on the model.
• Selectable output rates — Includes computer-video output rates from 640x480 to
1920x1200, and HDTV rates up to 1080p/60, and 2K (2048x1080).
• Integrated DTP inputs and DTP output (IN1608 DTP only) — Support digital
signal transmission of HDMI, DisplayPort, DVI, 3G-SDI, or VGA plus control and analog
audio over a single shielded twisted pair cable, providing high reliability and maximum
performance on an easily installed cable infrastructure.
• Integrated HDBaseT-compatible output (IN1608 HDBT only) — Supports video
and embedded audio, plus bidirectional RS-232 and IR signals to an
HDBaseT-compatible display over a single shielded twisted pair cable.
Audio Features
• Front panel output volume control — Provides convenient access to volume control
for program audio (default), mic volume, or output volume.
• 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 — Adjusts gain or attenuation 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.
• 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 transitions — Ramps audio output down and then ramps up to
match the video during switching transitions.
• Integrated audio delay — Automatically delays audio output to compensate 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 2-channel PCM audio to the
analog outputs, or passes bitstream formats. Multi-channel bitstream formats can also
be passed to HDMI outputs.
• Mic ducking — Reduces program audio when a microphone signal is detected.
• Automatic clip limiter — Detects the onset of clipping, automatically reducing gain to
eliminate clipping. This protects speakers and amplifiers from distortion.
• Available with energy efficient Class D stereo or mono amplifier (IN1608
amplifier and IN1608 IPCP models only) — The SA models offer a stereo power
amplifier with 50 watts per channel into 4 ohms and 25 watts per channel into 8 ohms,
while the MA models offer a mono 70 volt power amplifier with 100 watts rms output.
Both feature an Extron exclusive, 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.
