(See Rear Panel.) The LED will light when this input is selected.
S-VHS – Press this button to select the S-VHS input source. The LED
will light when this input is selected. (See Rear Panel connectors.)
Hue – This button allows the Hue (tint) level to be adjusted. Hold the
button while pressing the right or left arrow buttons, the selection
will be indicated on the Range Bar (- +).
Detail – This button is used to adjust the Detail (sharpness). Hold the
button while pressing the right or left arrows, the amount of range
will be indicated on the Range Bar (- +).
Range Bar and -/+ Buttons – This is an LED bar which indicated the
minimum or maximum range scale for Hue and Detail. The (-/+)
buttons are used to make adjustments.
Gamma – This switch turns the Gamma (color) Correction On or Off.
The LED will be lit when Gamma correction is selected. Most
signals are already Gamma-corrected. Additional correction may
make the picture look worse.
Preset – When the LED is lit, the Extron factory presets for Hue,
Detail and Gamma are in effect. When the LED is not lit, user
settings (program) are in effect.
Memory – Each input has memory to store one customized setting.
This button allows those user-programmed settings for Hue, Detail
and Gamma to be saved for the current selected input. This button
becomes effective when it is pressed, and held, until the Hue,
Detail and Gamma LEDs are lit.

Installation and Operation
Auto/Manual – When this switch is in the Auto position the CD 400
will automatically select the active input. If both inputs are active,
the Video input will have priority. When the CD 400 is in the
manual mode of operation the inputs may be selected via the
Front Panel Input switches or by Remote control (Rear Panel).
DIP Switches– The CD 400 has four DIP switches for operation with
the various video standards. Their functions are:
1. VCR – If the input source is a VCR this switch must be in the On
position to compensate for timing variances common with VCRs.
2. Program Standard – With this switch in the On position, the user
may select one of seven preset video standards (described
below). If the video standard is unknown, DIP switch #2 must be
Off, then the CD 400 will automatically select the video standard
which most closely matches the input signal.
3. Serration Remove – Some display devices do not operate
properly when serration pulses are present. When DIP switch #3
is On (up), these pulses will be removed from vertical sync
interval; with the switch Off serration pulses are allowed to pass.
4. Spare (not used)
Video Standard Select – This rotary switch allows the CD 400 to
select from seven video standards. Before using this switch, DIP
switch #2 must be On. The switch positions are as follows:
0 = PAL - B/G, -H, -1, 50 Hz; 1 = PAL +N, 50 Hz;
2 = SECAM 50 Hz; 3 = PAL -M, 60 Hz; 4 = PAL 4.43, 60 Hz;
5 = NTSC, 60 Hz; 6 = NTSC, 4.43, 60 Hz
Output Sync – The CD 400 has two choices for the decoded video
output. This is selected by the H/HV toggle switch located
between the H/HV and V connectors. In the H position the output
signal is RGBHV (separate Horizontal and Vertical Sync). In the
HV position the output signal is RGBS (Composite Sync on the
H/HV connector). In the HV position, the V connector is not used.
Remote – This connector allows input selections to be
made by remote control. The Remote port uses a
9-pin connector located on the rear panel with a
pin configuration as follows:
Pin Function Pin Function
1 Composite Video status 2 Not used
3 Not used 4 +5 Vdc (source 50 mA)
5 Ground 6 Common
