manual abstract
All switching functions and most video / audio adjustment functions can be accessed using the front panel. A few adjustments are available only through RS-232 control (see pages 16 - 19). Using the Front Panel Controls The control panel is divided into three types of control buttons: Input Select Buttons are the four large buttons on the left end of the panel. Audio / Video Adjustment Buttons are located in the center and include a pair of small buttons to adjust each parameter up or down. Function Buttons are three small buttons located on the right end of the panel which toggle between various modes. INPUT SELECT Buttons The buttons labelled VIDEO 1, VIDEO 2, VIDEO 3, and RGB may be used to select the desired input video source. The stereo audio associated with that input will automatically be selected at the same time. Whenever the unit is first turned on, INPUT 1 is automatically selected. The RGB input is passively routed through to the output at power down. To select an input, press and release one of the INPUT SELECT buttons. A green LED will light in one of the four buttons to indicate the current selection. The INPUT indicator LEDs work in conjuction with the VOLUME, HUE, COLOR, and CONTRAST up and down adjustment buttons. When an input source is being adjusted the corresponding INPUT SELECT LED will flash. If the LED stops flashing while adjustments are being made, the controls have reached the upper or lower limit of their adjustment range. Storing Settings The INPUT SELECT buttons are also used to store the unique audio and video settings for input channels 1 - 3 and the VOLUME setting on Input 4. By following the procedure which follows, each input source can be fine tuned and all settings stored for automatic recall whenever that input is selected: 1. Select the desired input using an INPUT SELECT button. 2. Make all desired audio and video adjustments for that input source. 3. Save all settings by pressing and holding the same INPUT SELECT button for five seconds. The INPUT SELECT LED will flash to indicate that all settings have been stored for that input. 4. Repeat steps 1 - 3 for each input source. The Store Settings procedure stores all important parameters for each input including Volume, Hue, Color, Contrast, Gamma, Video/S-Video, Doubling Mode, and SECAM enable/disable. If changes are made to an input and the settings are not stored, those changes will be lost if the unit is switched to a different input. The unit always recalls the last stored settings whenver an input is selected. IIN1222 / IN1422 / IN1510 / IN1710 OPERATIONS MANUAL -REV. 2 12/04/99 ©1994 -INLINE, INC. VOLUME Control Volume levels may be adjusted and stored for each of the four inputs in order to compensate for different audio input levels from the various sources. The volume circuitry is active, allowing the output signal voltage to be set either higher or lower than the original input signal. Press the upper button to increase the volume level or the lower button to decrease the volume level. If either button is pressed and quickly released, the volume level will change up or down by one step out of a total adjustment range of 40 steps. If either button is pressed and held the volume will quickly increase or decrease. If no volume level has been stored for an input, the factory default level (15 steps below maximum) is automatically recalled each time the input is selected or at power on. Bass and treble can also be adjusted and stored for inputs 1 - 4 using RS-232 commands (pages 18 & 19). HUE Control This control functions for Inputs 1 - 3 when receiving NTSC input signals (it has no effect on PAL or SECAM input signals). The HUE control has no effect on the passive RGB input. The top button skews the hue phase toward the Red end of the color spectrum and the bottom button adjusts the phase towards the Green end of the spectrum. Pressing either button once quickly adjusts the hue setting by one step out of a total adjusment range of 63 steps. Press and hold either adjustment button for a continuous rapid hue adjustment. The factory default setting is in the middle of the range. COLOR Control The unit employs an automatic color level circuit, and the color saturation level can be adjusted over a limited range (±5%). The COLOR control will not reduce the color to zero. The COLOR control has no effect on the passive RGB input. The top button increases the color saturation and the bottom button decreases the color saturation. Pressing either button once quickly adjusts the color setting by one step out of a total adjusment range of 8 steps. Press and hold either adjustment button for a continuous rapid color adjustment. The factory default setting is three steps above the minimum setting. CONTRAST Control Along with the GAMMA control, the CONTRAST control is very critical for proper adjustment of the unit. The control labeled CONTRAST actually controls both contrast and sharpness. The unit has been programmed with 32...
