IIN1222 / IN1422 / IN1510 / IN1710 OPERATIONS MANUAL - REV. 2 12/04/99 ©1994 - INLINE, INC.
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.
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).
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.
