GAMMA Button

Gamma correction is an effective tool used to compensate for the non-linear response of most display devices. The gamma setting may also be changed as required to accomodate the wide variation of video gain and contrast characterstics found in various video program sources. INLINE scan doublers and decoders offer eight different gamma curve adjustments (seven active gamma curves plus no gamma). Along with the CONTRAST control, the GAMMA control setting is critical to proper adjustment and should generally be set first with all other controls set to the factory default position.

The default setting is Gamma Curve 0 (no gamma correction). Each time the GAMMA button is pressed, the unit moves one click up to the next gamma curve. The complete cycle includes eight gamma settings, beginning with Gamma Curve 0 and ending when Gamma Curve 7 is reached, at which point it jumps back to Gamma Curve 0.

The GAMMA select LED is off when Gamma Curve 0 is selected (no gamma correction).

The GAMMA select LED is on when an active gamma curve is selected (Curves 1 - 7).

S-VIDEO / VIDEO / SECAM Button

Inputs 1, 2 and 3 can accept either S-Video or Composite Video input, but the unit must first be set to accept and decode one one these formats. The primary function of this button is to toggle between S- Video or Composite Video input.

S-Video input is selected when the LED is on (factory default setting).

Composite video input is selected when the LED is off.

It is very important to store the appropriate S-Video / Video setting for each input source during the installation process (see Store Settings procedure listed

on page 8). This will insure proper decoding when switching between inputs.

Selecting SECAM Video

The unit will automatically detect and decode NTSC and PAL input signals. SECAM decoding is normally disabled (factory default setting) and must be manually selected using the S-VIDEO / VIDEO / SECAM button. To decode SECAM input signals, hold down the button until the INPUT SELECT LED flashes three times and a normal video image is displayed. Store this selection (Store Settings, page 8).
