IN3254 1 Chapter One Introduction About this Manual About the IN3254 Distribution Amplifier Features Installation Connections and Controls Operation and Troubleshooting
Introduction About this Manual This manual describes the function and installation of the Extron IN3254 Distribution Amplifier (DA). About the IN3254 Distribution Amplifier The Extron IN3254 is a high performance RGBHV distribution amplifier. This DA includes one input and four outputs on BNC connectors. It features a two-position gain switch that affects the output level on all RGB channels, and compensates for signal level loss that occurs over long cable runs.
Power LED — A green LED lights to verify that the DA is receiving power. Sync Level — An internal sync level control provides precise adjustment of the sync portion of the video with the sync signal. Installation The IN3254 can mounted in a convenient location using the Extron universal 2U rack shelf (Extron part# 60-032-01). 1. Turn all equipment off and ensure that the source device, the DA, and the output devices have been disconnected from the power source. 2.
Introduction, cont’d 5. Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (such as the use of power strips). Rack mount the unit using an optional Extron 2U universal rack shelf (Extron part #60-032-01), as follows: 1. Remove rubber feet if they were previously installed on the bottom of the unit. 2.

Power LED — A green LED lights to indicate that the IN3204B is receiving power. Video input connectors — Connect an RGBHV, RGBS, RGsB, RsGsBs, component video, S-video, or composite video device to these female BNC connectors.
Introduction, cont’d SYNC LEVEL VIDEO GAIN Sync Level: Set this switch to adjust the sync portion of the video with the sync signal. HI LOW HI — Applies 5 volts peak-to-peak. X1.3 X1 LOW — Applies 3 volts peak-to-peak. N Adjustments apply to all four outputs. Input and output connections RGB and component video inputs — Connect an RGBHV, RGBS, RGsB, RsGsBs component video, S-video, composite video source to these BNC connectors.
Operation and Troubleshooting Connect the power cords and turn on the displays (projectors or monitors), the DA, and the input device (computer). The image should appear on the screens. If the image does not appear or is not displayed correctly: 1. Ensure that all devices are plugged in. 2. Make sure that each device is receiving power. The DA’s front and rear panel power LEDs indicate if the DA is receiving power. 3. Check the cabling and make adjustments as needed. 4.
