IN1608 xi Scaling Presentation Switcher • Introduction
2
Product Description
The Extron IN1608 xi is an HDCP-compliant scaling presentation switcher with four HDMI
inputs, two configurable analog video inputs, and two Extron DTP inputs. It includes two
HDMI outputs and one DTP/HDBT output, configurable separately. Amplifier models
have an integrated Class D audio power amplifier, while IPCP models have a built-in IPCP
Pro control processor for complete AV system control. The DTP inputs and output work
with DTP endpoints to extend video, audio, and bidirectional control signals. Each DTP
transmitter and receiver link requires a single shielded CATx cable. The DTP/HDBT output is
configurable for HDBaseT compatibility by means of a switch on the IN1608 xi rear panel.
Integrated Digital Twisted Pair Extension
The two DTP twisted pair inputs can receive signals from remote DTP transmitters in
areas such as a conference table, lectern, or wall for connecting a guest laptop. The DTP
inputs and the DTP output enable bidirectional RS-232 and IR signals to be inserted from
a control system and transmitted over the shielded CATx cable along with the video and
audio, enabling control of a source or display. Additionally, the IN1608 xi can send power to
selected DTP transmitters and receivers over the same shielded CATx cable.
DTP input and output signals
The DTP inputs and outputs are proprietary signals that are created within any of the Extron
DTP Extender systems and transmitted over a single shielded twisted pair (STP) cable.
The IN1608 xi accepts DTP inputs from transmitting devices such as the DTP T USW 333.
Depending on the connected transmitting model, the transmitter generates the DTP signal
from a variety of video and audio inputs, including HDMI, DVI, analog VGA, and embedded
and analog audio. The DTP signal can also include bidirectional RS-232 and IR control
signals from the connected transmitting and receiving devices or inserted locally, on the
IN1608 xi.
Depending on the range of the transmitting or receiving device, the DTP inputs and outputs
can each travel up to 330 feet (100 meters) or 230 feet (70 meters) without a loss of signal
integrity. The TP inputs and outputs also support RS-232 insertion and dedicated universal
asynchronous receiver/transmitters (UARTs).
Video Processing
The IN1608 xi scales HDMI, RGB, component, S-video, and composite video signals to a
common high resolution output. It provides 30-bit color processing and motion-adaptive
deinterlacing for input signals up to 1080i. The analog video inputs are configurable for
RGB computer video, HDTV, component video, RGBcvS video, S-video, and composite
video. Additionally, the color space and chroma subsampling of the HDMI output can be
automatically set to ensure compatibility with a connected DVI or HDMI display.
Audio Integration Capabilities and Available Power Amplifier
The IN1608 xi can also serve as the central component for audio system integration. It
includes eight-input audio switching, two mic/line inputs with phantom power, HDMI audio
embedding and de-embedding, and several audio processing features for mixing, ducking,
tone adjustments, and more. Audio configuration features and options can be accessed
through the internal web pages, the Product Control Software (PCS), and the on-screen
display (OSD).
IN1608 xi models are available with a choice of integrated power amplifiers. IN1608 xi SA
models deliver stereo power amplification with 50 watts rms per channel into 4 ohms or
25 watts rms per channel into 8 ohms, while IN1608 xi MA models provide mono 70 volt
amplification with 100 watts rms output.
