The functions of the front panel controls are described in the following sections.

Input selection

The four numbered Input selection buttons (1 – 4) will select from among the 4 separate input sources:

Input 1: selects either a composite video or S-video input

1 2 3 4

Input 2: selects either a composite video or S-video input

Input 3: selects a composite video input

Input 4: selects a composite video input

The Input buttons correspond to the numbered input connectors on the rear panel. After you select an Input selection button, the green LED indicator above the button lights. Selecting an input selects the input image to output to a window. To deselect an Input button, press that button again.

The MVP 104GX can output all selected input images to the single S-video output and the two composite video outputs simultaneously.

INPUT 1	INPUT 2	INPUT 3	INPUT 4	OUTPUT
IN	IN	IN	IN	A
OUT	OUT
		OUT	OUT	B	C

Freeze control

Pressing the Freeze control button while pressing an Input
selection button freezes the selected input image window. The	1 2 3 4 FREEZE
red LED below each Input selection button lights whenever the
input image is frozen. To unfreeze the individual input
windows, repeat this process for each frozen input image
window.

The only way to freeze or unfreeze all input window images in one operation is through an RS-232/RS-422 command. See the “Programmer’s Guide” chapter.

output and does not light any LED.

Selecting past audio input 4 switches audio to audio input 0 (no audio is selected). The audio can also be deselected through an RS-232/RS-422 command and using 0 as the audio input number. See the “Programmer’s Guide” chapter.
