Audio Features
All CrossPoint 300 Series HVA audio-capable models feature a full range of audio input and
output adjustments. Audio input gain and attenuation may be adjusted for each channel
individually, eliminating the noticeable and sometimes jarring volume differences when
switching between sources.
Audio output volume control is also provided for each individual output. Signal levels may be
adjusted from the front control panel or through serial control, providing a simple way to set
audio volume levels without an audio preamplifier.
In addition, audio breakaway provides the capability to separate the audio signal from its
corresponding video signal, allowing the audio channels to be operated as a separate matrix
switcher within the system.
Control Options
For ease-of-use in a variety of environments, all CrossPoint 300 Series matrix switchers are
equipped with a full range of control options, including front panel control, RS-232/RS-422
serial control, and several wired remote control panel options.
The QS-FPC
™
- QuickSwitch Front Panel Controller allows simple, touch-of-a-button
selection of inputs and outputs directly from the front panel of the CrossPoint 300 switcher.
The CrossPoint 300 Series can also be controlled using optional Extron control panels
and keypads.
For optimum signal reproduction, each input and output is individually isolated and buffered. Any
input can be switched to any one or all outputs with virtually no crosstalk or signal interference
between channels. In addition to RGBHV signals, CrossPoint 300 Series matrix switchers
are designed to accommodate the widest range of signal routing requirements, and are fully
compatible with RGBS, RGsB, HDTV, component video, S-video, and composite video signals
as well. To ensure full confidence when switching between varying computer-video sources, all
CrossPoint 300 Series matrix switchers include Extron's exclusive ADSP
™
- Advanced Digital
Sync Processing.
ADSP
Extron's ADSP is an all-digital process that corrects and restores the sync signal as it passes
through the switcher. First, ADSP restores sync to TTL levels, 5.0 V p-p, ensuring that the
projector or monitor accurately locks to sync and displays a stable image. Second, ADSP
corrects the signal waveform to create sharp rising and falling edges, ensuring a more stable
and reliable image in systems with different signal sources or cable lengths. Whether signal
losses and distortion are caused by long cable runs, variations in display graphic card outputs,
or low sync levels found in many laptop computers, ADSP significantly reduces sync related
problems, improving signal compatibility with many digital display devices.
