Input Select:
The large buttons labeled
INPUT 1
,
INPUT 2
,
INPUT 3
and
INPUT 4
in the
Input
Select
section are used to select the desired input. After turning on the IN1404, press and release the
desired
Input Select
button. A green LED will light underneath the button to indicate the selected
input. The stereo audio signal associated with the input will automatically be selected at the same
time. All audio, video, and input settings for each input are stored internally (in memory) so the
adjustment(s) will not have to be repeated after they are optimized. To switch to another input,
simply press and release another numbered
Input Select
button.
When powered up, the scaler automatically returns to the last configuration, including the last
input selected.
Blank:
The
BLANK
button can be used at any time to show a blank screen on the display device.
When blank is engaged, the output setting goes to black but the sync signals continue, ensuring that
the data display device retains sync lock. Simply press and release the button to engage blanking (the
green LED underneath the button will illuminate), and press and release it to disengage.
The
BLANK
button has no effect on input 3 or input 4, which are configured as passive inputs.
Freeze Frame:
Allows users to
freeze the video signal and display a still image. Simply press and
release the button to engage the function (the green LED below the button will illuminate), then press
and release again to disengage. The freeze frame button has no effect on input 3 or input 4, which are
configured as passive inputs.
Volume:
The volume buttons are used to regulate the level of the audio signals routed through the
scaler. Use the
/
volume buttons to increase or decrease the audio level for the current input.
Press and release a button to raise or lower the volume level by one step, or press and hold a button to
change the level continuously. The IN1404 saves the volume levels for each input.
Mute Audio:
Mutes the audio for the selected input. Press the button to engage (the green LED
below the button will illuminate), and press it again to disengage.

to access and adjust the on-screen menu displays.

system is provided on the next page.
