3. Configuration & Operation
3.1 Front-Panel Buttons and Indicators
An image of the front panel for the 4x4 matrix is shown below. The 4x2 units have
fewer OUTPUT buttons, but otherwise are the same.
Figure 7 – HSM-04-04 front panel controls & indicators
The front panel can be used for the following purposes:
• Monitor & Control Power On/Off status
• View current Input/output routings (ties) on Routing Status LED Grid on the
front panel
• Make new ties either starting from input or from output
• Recall preset patterns
• Save preset patterns
All of the front panel switches have built-in LEDs that help in the operation. Front panel
functions are designed for maximum intuitiveness. With just a little practice, one can
easily learn to monitor and control the matrix.
3.2 Turning the unit on and off
To turn the unit on, press the power button. The unit performs a simple LED test where
all buttons and LED’s are gradually turned on over a few seconds. Then the matrix will
recall the last routing pattern prior to being shut -down and update the Routing Status
LED Grid.
To turn the matrix off, press and hold the power button for 5 seconds. This is done to
prevent accidentally turning off the unit if the power button is accidentally pressed.
