MVP 104GX 1 Chapter One Introduction About the MVP 104GX MVP 104GX Features
Introduction About the MVP 104GX Extron’s MVP 104GX is a multi video processor featuring four inputs, three outputs, audio switching, and genlock capability. The MVP 104GX accepts up to four video inputs, both composite and S-video, and can simultaneously output all four video sources to a single output device. Each of the three outputs can display up to four discrete, scalable windows, one for every input source.

Installation If the MVP 104GX is to be rack mounted, follow the Rack Mounting Procedure below before proceeding any further. Otherwise, skip to Rear Panel Connectors and continue with the installation. Rack Mounting Procedure 1. Before proceeding, verify that the MVP 104GX is not cabled to any devices or connected to any power source. 2. Position the MVP 104GX in the mounting rack so that the 4 slots in the mounting ears are aligned with the rack mounting holes.

Installation, cont’d 13 Genlock input — Connect an external black burst signal for genlocking the video signal in broadcast or other sync-critical applications. 14 Genlock output — Connect any downstream equipment that requires genlocking for broadcast or other sync-critical applications. Connecting the MVP 104GX The MVP 104GX can be connected to as many as four input devices simultaneously and output to as many as three devices simultaneously.
4 Connect up to three output devices to the MVP 104GX using composite video output A, composite video output B, and S-video output C. 5 For stereo audio input, connect up to four audio sources to audio inputs 1, 2, 3, and 4. See the following Audio input and output section. 6 For stereo audio output, connect an audio output device to the 3.5 mm stereo audio output connector. See the following Audio input and output section.
Installation, cont’d Balanced audio 1. Attach the audio cable to a balanced speaker input connector (tip, ring, and sleeve), as shown here. Tip (+) Sleeve Ring (-) Tip (+) Sleeve (ground) 2. Attach the other end of the audio cable to the audio cable connector (Extron part number 10-319-10). Fasten the captive screws inside the audio cable connector as shown in figure 2-4. Balanced Audio Tip Ring Sleeve (s) Tip Ring Connect the sleeve(s) to ground (GND).
Genlock connections A genlock (black burst generator) device can be connected to the MVP 104GX via the BNC connectors shown below. The genlock feature allows the MVP 104GX to be synchronized with other system components for seamless vertical interval switching between sources. See Setting Up Genlock and Vertical Interval Switching in this chapter.
Installation, cont’d To synchronize the MVP 104GX’s video output with a genlock signal, follow these steps: 1. Power up and turn on all the devices that will use the genlock signal. The devices must be on for at least 15 to 20 minutes before proceeding with any adjustments. 2. Connect the active timing source signal to the Genlock In connector on the rear panel.
Oscilloscope displays What you see on the oscilloscope while adjusting the MVP 104GX to match the genlock signal depends on the type of signal used, the type of oscilloscope, and the procedure the scope requires. This section shows some examples of oscilloscope displays. Figure 2-6 below shows the genlock input signal (top) and an out-of-alignment NTSC composite sync output signal (bottom) displayed on a waveform monitor to check for alignment.
Installation, cont’d Figure 2-8 below shows an example of a view of a vectorscope during adjustment of the color subcarrier phase (SC/H). The subcarrier phase should be aligned to 0º (indicated in the figure by the triangle).
