VAMP2 Series User Guide Front Panel Features When CVBS 1 or 2 is selected, one of the two corresponding CVBS inputs on the rear panel is selected for monitoring. See the Audio Select button (page 14) for information about selecting audio inputs with video monitoring. Note that the selected CVBS LED will glow green when selected. • Channel Indicators (LEDs, 1 through 4): These four LEDs (1, 2, 3, and 4) indicate when the associated channel is assigned to one or both speakers.
VAMP2 Series User Guide Front Panel Features • Headphone Jack (1/4” Connector): Select the headphone audio sources as you would for the internal speakers. When you plug in headphones, the internal or external speakers will mute. • Tint (TNT): Turn this potentiometer to adjust the color hue of the video image (for NTSC signals only). • Chroma (COL): Turn this potentiometer to adjust the color saturation of the video image.
