Audio input and output connections

4Connections for balanced and unbalanced audio inputs — Each input has a

3.5mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are included with each CrossPoint switcher, but you must supply the

audio cable. See figure 2-3 to wire a connector for the appropriate input type and impedance level. High impedance is generally over 800 ohms.

The audio level for each input can be individually set, via the front panel or RS-232, to ensure that the level on the output does not vary when switching from input to input. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5, Matrix Software for details.

5Connections for audio outputs — These 3.5 mm, 5-pole captive screw connectors output the selected unamplified, line level audio. Connect audio devices, such as an audio amplifier or powered speakers. See figure 2-5 to properly wire an output connector.

CAUTION

Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

By default, the audio output follows the video switch. Audio breakaway, commanded via the front panel, under RS-232 control, or Windows-based control program, allows you to select from any one of the audio input sources. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5, Matrix Software for details.

42 HVA specifications

The Extron Electronics 42 HVA (High Voltage Adapter) is a notable product designed for enhancing audio-visual systems. It is primarily focused on the distribution of high-definition video signals over long distances, making it a valuable asset for educational institutions, corporate environments, and large venues.

One of the standout features of the Extron 42 HVA is its ability to support HDBaseT technology. This allows for the transmission of uncompressed HD video, audio, Ethernet, control signals, and power over a single CAT6 cable. This capability not only simplifies installation but also reduces the amount of cabling required, allowing for a cleaner and more organized setup.

The 42 HVA boasts a robust design that can handle resolutions up to 4K, ensuring that high-quality video can be delivered without loss of fidelity. The unit is equipped with multiple input options, catering to a variety of sources such as computers, projectors, and displays. Its compatibility with different formats and resolutions makes it a versatile choice for any AV setup.

Another key feature is its advanced signal management technology. The 42 HVA supports EDID (Extended Display Identification Data) management, which ensures that the connected devices are communicating correctly. This helps to prevent issues such as resolution mismatches and allows users to achieve optimal performance from their AV system.

Additionally, the 42 HVA incorporates a feature known as automatic cable equalization. This technology enhances the signal integrity over long cable runs, allowing the device to maintain the quality of the transmitted video even at greater distances. This is particularly important in large venues where cable lengths can be significant.

For ease of use, the Extron 42 HVA includes an intuitive interface that simplifies the setup process. The device can be easily integrated into existing AV systems, and its compact design allows for flexible mounting options. This adaptability makes it an excellent choice for both new installations and upgrades to existing systems.

In summary, the Extron Electronics 42 HVA is a powerful tool in the realm of AV technology. With its HDBaseT support, high-resolution capabilities, and advanced signal management features, it meets the demands of modern audio-visual environments. Its design, functionality, and versatility make it an ideal solution for delivering high-quality video signals over long distances in a range of professional settings.
