Configuration

Sync impedance DIP switches

Set the front panel DIP switches to correct for sync impedance mismatches, or to solve laptop compatibility issues on the video input or reflection problems on the video output.

Switch 1 (sync input impedance) — The default setting is Off (510 ohms). If the image from the laptop is unstable, slide DIP switch 1 to On (10k ohms).

Switches 2-7 (sync output impedance) — Each of these switches controls a pair of outputs simultaneously (see the table below). The default setting is Off (50 ohms). If the front LED is green and all the input and output cables are connected correctly, but there is no image on the display, slide the switch to On (75 ohms).

Mute control

The mute control provides a way to mute individual outputs, or all outputs at once. Audio and video for each output are muted simultaneously.

Each output is assigned to a pin on the captive screw connector. To mute any output, short its pin to the ground pin (). Multiple outputs can be shorted at the same time. To mute all outputs at once, short pin A (all) to the ground pin.

The P/2 DA8 A model uses two 5-pole, 3.5 mm captive screw connectors.

The P/2 DA12 A model (shown at right) uses two 4-pole, 3.5 mm connectors and two 3-pole, 3.5 mm connectors.

If you have problems with the output from any of these distribution amplifiers, please consult the Troubleshooting section of the full manual, which is available online at www.extron.com.

P/2 DA12, P/2 DA8 specifications

Extron Electronics is a renowned company recognized for providing innovative and high-quality AV (audiovisual) solutions. Among their extensive range of products are the P/2 DA12 and P/2 DA8, which are designed to enhance video distribution in various environments. These distribution amplifiers are particularly favored in commercial settings like conference rooms, educational facilities, and control centers.

The P/2 DA12 offers twelve outputs, while the P/2 DA8 features eight outputs, allowing for flexible video distribution from a single input source. Both models support resolutions up to 1920x1200, ensuring compatibility with a wide range of display devices such as projectors, monitors, and TVs. This high-quality video output is essential for maintaining the clarity and detail required in professional presentations and high-stakes environments.

One of the standout features of the P/2 DA series is Extron's advanced signal processing technology. This includes Automatic Cable Equalization, which compensates for signal loss over extended distances, ensuring that the video quality remains consistent even when using long cable runs. The P/2 DA amplifiers also integrate Extron's unique 4k-capable circuitry, making them ready for future-proofing as AV technology continues to evolve.

Furthermore, both models are equipped with individual gain controls for each output. This feature allows users to optimize the signal strength delivered to each display, accommodating different cable lengths and equipment configurations. The amplifiers also provide comprehensive status LED indicators that enable easy monitoring of device functionality and signal status, a crucial aspect in professional setups.

Reliability is another significant characteristic of the P/2 DA12 and P/2 DA8. These devices are built with robust construction, ensuring durability in demanding environments. They also feature universal power supplies that work globally, facilitating seamless integration into various installations without the need for additional converters.

Finally, installation is streamlined with the inclusion of a compact design, making it easy to mount in racks or on surfaces without occupying much space.
