Using the Front Panel Controls
Making Selections
AV Button
Use the following button sequence to make a video selection: input number, AV then output number or
numbers. For example to select input 2 to output 4 press the following buttons: 2 AV 4, where 2 is in the
INPUTS group and 4 is in the OUTPUTS group.
Video and Audio Buttons (SY-MMU-88A Only)
Note that the SY-MMU-88A Matrix switcher also has Video and Audio buttons, these can be used to
independently switch only the video signal or only the audio signal where these signals are provided
separately. HDMI signals have embedded audio data and therefore the HDMI audio will always switch with
the video selection. The Audio button only affects analogue audio signals connected to the terminal block
connections below the video input and output cards.
Operation is exactly the same as for the AV button.
Backspace, Comma and Enter Buttons
For the SY-MMU-1616 and SY-MMU-3232, there is both a comma button and an Enter button. The comma
button is used to separate the output channel values when a single input is being sent to multiple outputs
simultaneously in the same command.
The Backspace (
←
) button deletes the last key entry to allow the user to make corrections to the
command being entered at the front panel, prior to pressing the Enter button.
The Enter button on these same Matrix Switchers is always used to conclude every command entry that
require numerical input.
All and Through Buttons
The All button has two modes:
1.
Send a single input to all outputs simultaneously: for example,
10 ALL
will route input 10 to all
available outputs.
2.
When combined with the Through Button the Matrix switcher will connect each input channel to
its corresponding output channel, thus: input 1 goes to output 1, input 2 goes to output 2, input 3
goes to output 3, and so on. The button sequence is
All
followed by
Through
.
Undo Button
The Undo button causes the Matrix Switcher to revert to the input / output configuration it had prior to
the last command sent to it.
