The Extron P/2 DA8 and P/2 DA12 are VGA distribution amplifiers with eight and twelve outputs, respectively. Each unit accepts a single VGA input signal and actively splits it for distribution to multiple outputs. Offering 350 MHz (-3dB) of RGB video bandwidth, the P/2 DA8 and P/2 DA12 are compatible with VGA-QXGA graphic cards, projectors and flat panel displays. Outputs are individually buffered and amplified to help maintain the original signal integrity and eliminate noise interference. ID bits are routed to output one for local monitor support. P/2 DA models are ideal for use in applications where one computer-video signal needs to be routed to multiple displays, such as rental and staging, courtrooms, conference rooms, and training facilities. 

The P/2 DA8 and P/2 DA12 offer selectable input and output sync impedance. This provides better compatibility with a wide range of laptop types. These models also feature individual output muting via contact closure. This feature allows the user to mute any one or all outputs with simple pushbutton relay control, and eliminates the cost of an extra control system serial port.

The P/2 DA8 A and P/2 DA12 A have all the features of the P/2 DA8 and P/2 DA12 and add eight-output and twelve-output stereo distribution amplifiers, respectively. Both feature active PC audio buffering which converts unbalanced PC audio to balanced, line level signals, eliminating noise over long cable runs. Unbalanced stereo audio is input on 3.5 mm stereo mini jacks, while balanced or unbalanced stereo audio is output on captive screw connectors. Using pre-terminated cable assemblies, such as Extron's VGA with Audio Cables, eliminates crimping and makes installations faster and easier.

Features

  • 350 MHz (-3dB) RGB video bandwidth, fully loaded — Provides optimum signal integrity at the highest computer-video resolutions.

  • Compatible with VGA-QXGA resolutions

  • DDC signals and ID bits routed to local monitor output — Maintains compatibility with Windows¢ç Plug-and-Play local monitors.

  • Individual output muting via contact closure — Mute any one or all outputs with simple pushbutton or relay control.

  • Selectable input and output sync impedance — Sync impedance can be set for optimum compatibility with a wide range of laptop computers.

  • Active PC audio buffering — Converts unbalanced PC audio to a balanced, line level signal, eliminating noise over long cable runs.

  • Internal universal power supply
