Analog Way Quattro Value - Manual (Page 18)

OPERATING MODE
The device can be used in two different switching modes.
• The SEAMLESS MODE , allows switching seamlessly, fading and titling between the “reference” COMPUTER
input and the other inputs. Other inputs are scaled to the same format as the “reference” COMPUTER format.
NOTE : Input #1 and #8 can be used as the reference capter input.
NOTE : The “reference” Computer is not scaled.
• The FAST SWITCHING MODE allows selecting an output format corresponding to your application. All video
inputs are scaled to the selected format. The switching between two inputs will go through a fade colored tran-
sition. The output rate can be selected between 60 Hz, 75 Hz or can be synchronized to one of the video input
frame rate in order to improve the motion picture. In this case, the output frame rate will be 50 Hz if the input is
in PAL or SECAM, and 59.94 Hz if the input is in NTSC.
3-1. SETTINGS
1) We recommend resetting the device to its default values, with the LCD menu (CONTROL > Default value > yes)
before proceeding.
2) Select a switching mode with the LCD menu (SWITCHING > fast switching or seamless). Please see the
Switching mode table below.
3) Select the Auto settings function with the LCD menu (INPUT > Auto settings). This function will detect automa-
tically the source type connected to the inputs of the device. Sometimes, the auto setting may not detect the
source type : in this case select manually the source type with the LCD menu (INPUT > Input type).
4) If you have selected the fast switching mode : select one of the output formats with the LCD menu (OUTPUT >
output format).
NOTE : For fixed pixels display devices (DMD, LCD, PLASMA…), always select the output format corres-
ponding to the native resolution of your device. Thus, the display device will not have to scale the image
and the result will be better.
NOTE : In SEAMLESS mode, the output format is the same as the “reference” computer format.

3-2. SWITCHING OPERATIONS
• The device allows 4 different switching effects : CUT * , FADE * , FADE COLOR and CLEAN CUT. The CUT effect al-
lows switching seamlessly between 2 sources. The FADE effect allows fading out the displayed source while another
source is fading in. The FADE COLOR effect allows switching between 2 sources with a fading through the color of
you choice. The CLEAN CUT allows a clean switching thanks to a fast freeze of the displayed source.
• PIP * = Picture in Picture is also available effect.
• QXE421 also enables you to key text onto the displayed image (TITLE * effect).

! * The CUT, FADE, PIP and TITLE effects are active in SEAMLESS mode and only between the reference
computer input and the other inputs.
