P/2 DA8 and P/2 DA12 Series 1 Chapter One Introduction About this Manual Description of P/2 DA8 and P2 DA12 Series Features of P/2 DA8 and P2 DA12 Series
Introduction About This Manual This manual contains information about the Extron P/2 DA8, P/2 DA8 A, P/2 DA12 and P/2 DA12 A distribution amplifiers with instructions on how to mount, install, and operate these units. Unless otherwise specified, references to "the distribution amplifier" in this manual relate to the features or operation of all four of these models.
Features of P/2 DA8 and P/2 DA12 Series Bandwidth — 350 MHz (-3dB) RGB video bandwidth, fully loaded, which is compatible with resolutions from VGA to QXGA. Wide range of compatible signal types and resolutions — all models are able to accept and distribute RGBHV, RGBS, RGsB, RsGsBs, YUV (tri-level and bi-level sync), S-video and composite video signals. Power LED — located on front panel. It has a dual purpose as power indicator and input signal status.

Installation and Operation Installation Overview The distribution amplifiers can be mounted on tabletops, in racks and under furniture. Through-desk mounting is not recommended for these products. To install these units, follow these steps: 1. Turn off all electrical equipment. Make sure that the input sources, the distribution amplifier, and the output displays are all turned off, disconnected from their power sources, and connecting cables have been removed. 2.
overloading might have on overcurrent protection and supply wiring. Give appropriate consideration to the equipment nameplate ratings when addressing this concern. 5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).
Installation and Operation, cont’d Under-desk mounting Mount the unit under a desk or podium using the optional Extron MBU 149 kit (part #70-222-01) as follows: 1. Remove rubber feet if these have been installed on the bottom of the unit. 2. Using the provided #8 screws, attach the mounting brackets to the distribution amplifier (four screws on each side, as shown below in figure 2). Mounting Screws (2 Plcs) Each Side #8 Screw (4 Plcs) Each Side Figure 2-2 — Under-desk mounting the interface 2-4 3.

Installation and Operation, cont’d Operation After the distribution amplifier and its connected devices are powered up, the system is fully operational. If any problems occur, ensure that the cables are properly routed and connected. Sync impedance switches To solve laptop compatibility issues on the video input, or reflection problems on the video output, use these dip switches to correct for sync impedance mismatches.
Video Input and Output Connections All models are able to accept RGBHV, RGBS, RGsB, RsGsBs, YUV (tri-level and bi-level sync), S-video and composite video, and resolutions from VGA (640 x 480) to QXGA (2048 x 1536). The signal is distributed without modification: the output format follows the input format. To make input and output connections with other devices, follow these instructions: 1. Turn off the power to the distribution amplifier and the video source. 2.
Installation and Operation, cont’d Audio input For models P/2 DA8 A and P/2 DA12 A, use a female 3.5 mm mini Tip Ring Sleeve (TRS) connector to provide an unbalanced audio input. Switch off power to the distribution amplifier and audio source. Connect the audio source to the audio input socket on the rear Audio Input panel of the distribution amplifier. INPUT Wiring for the TRS connector is shown in the figure below. Tip (L) Ring (R) Sleeve ( ) Tip Left + Ring Right + Sleeve Ground 3.

Right Balanced Stereo Output CAUTION For unbalanced audio, connect the sleeve(s) to the center contact ground. DO NOT connect the sleeve(s) to the negative (-) contacts. Figure 2-8 — Audio output wiring Mute Control The mute control provides a way to mute individual outputs, or all outputs at once. Audio and video for each output is muted simultaneously.
Installation and Operation, cont’d Troubleshooting After input and display devices are connected to the distribution amplifier and all units are powered up, the system is fully operational. If any problems occur, ensure that the cables are properly routed and connected. Some common problems and diagnostic checks are shown below: If the LED light on the front panel is not on, the distribution amplifier is not receiving power.
