Front Panel Controls and Indicators
The ProTraXX includes controls to accommodate a wide variety of installations. The front panel
incorporates a 2x16 LCD display and Menu Knob, a blue power indicator, sixteen channel control
pushbuttons, a Mute pushbutton, media status/error indicator, a GPS status indicator, channel status and
rear input indicators, and a Compact Flash slot. All front panel controls can be locked using a PIN
number for systems requiring tamper-free operation.
Test Channel Buttons
The numbers next to the
test button match the
channel and file
numbers (i.e. Button
number 1 plays file
number 1 to channel 1,
Button number 2 plays
file number 2 to channel
2, etc.
The front panel contains a row of sixteen pushbuttons. These buttons allow
you to test play each of the unit’s 16 mono channels. When a test channel
button is pressed, the file with the same number as the button number will be
activated and played out the corresponding channel. Pressing a button once
plays the sound. Pressing it again while the sound is playing stops playback.
Channel Status LEDs
Front Panel Channel Status LEDs activate whenever a channel is playing (Green) or muted (Red) or
paused (Orange).
Input LEDs
Input LEDs will illuminate Green whenever the corresponding rear panel input is activated.
Mute All Button
A pushbutton on the far right of the front panel causes all channels to mute. Pressing the button once
causes all channels to mute. Pressing it again causes all channels to unmute.
