MicroSYNC Controls
The MicroSYNC controls are shown in bold black text on the front panel. The section below explains the effect each
control has on the installed MicroSYNC card.
Proc Amp Controls
The proc amp controls are applicable to MicroSYNC cards. The proc Amp controls are VIDEO LEVEL, BLACK
LEVEL, CHROMA LEVEL, and HUE LEVEL.
VIDEO
The VIDEO CONTROL button selects video level control for the shaft encoder. Changing the video level effects the
overall amplitude of the processed video signal, resulting in a change in the displayed picture contrast.
BLACK LEVEL
The BLACK LEVEL button selects black level control for the shaft encoder. Changing the black level effects the DC
level of the processed video signal, resulting in a change in the displayed picture brightness.
CHROMA LEVEL
The CHROMA LEVEL button selects chroma level control for the shaft encoder. The chroma level control changes the
color saturation of the processed video signal.
HUE
The HUE button selects hue control for the shaft encoder. The hue control changes the phase of the processed color
subcarrier, which effects the tint of the displayed picture.
Freeze Controls
TAKE and FRM/FLD are primary functions. STROBE is a shift function marked in italics under FRM/FLD.
TAKE
The TAKE button is used to toggle between FREEZE and LIVE modes. Note that when the unit is in the FREEZE
FIELD mode, and the FREEZE function is activated, the shaft encoder may be used to select one of the five
MicroSYNC fields captured when the FREEZE function was actuated.
FRM/FLD
This button is used to select between FRAME (FRM) and FIELD (FLD) FREEZE modes. The FRAME mode is
normally used for static scenes (i.e. no motion) because it provides better vertical resolution. The FIELD mode is used
to freeze scenes that contain motion. The shaft encoder can be used to select fields one through five. Also for the
MicroSYNC card, the freeze frame range is frame 1, frame 2 or 4-field freeze.
STROBE
The STROBE function is engaged by pressing and holding the freeze FRM/FLD button until the FRM LED begins to
flash. The STROBE mode is then entered when the FREEZE TAKE button is selected. When the unit is in strobe
mode, the shaft encoder may be used to select the desired strobe rate.
