GROUPED MIXERS
When Mixers are linked together, the first
Mixer in the group defaults as the master
Mixer, and each concurrent Mixer in the
group becomes a slave Mixer. Each slave Mixer in a group
will display “REMOTE CONTROL” in the main screen to
signify it is functioning in a group.
TEXT MESSAGES
The PRO Digital Overlay also displays
text messages in the main screen. This
allows the engineer to communicate with
players without using the intercom feature. After a message
is sent, it will continue to flash on the main screen until the
Mixer is adjusted (e.g. touch a knob, press a button). Text
messages can be sent from the Hear Back PRO iOS app
to all the Mixers in a session or to specific individual Mixers
equipped with a PRO Digital Overlay.
Send a Text Message to All Mixers in a Session:
1. Open the Hear Back PRO iOS app > Select the “Devices”
menu
2. Click on the text message icon > A dialog box will open.
3. Type a short text message (up to 36 characters) > Select
“Send” > The message will appear and begin flashing on
each of the Mixers’ main screens.
Send a Text Message to a Specific Mixer:
1. Open the Hear Back PRO iOS app > Select the “Devices”
menu
2. Swipe left on the Mixer to receive a message.
3. Select the “More” button to view additional functions.
4. Select “Send Text Message” from the drop down menu >
A dialog box will open.
5. Type a short text message (up to 36 characters) > Select
“Send” > The message will appear and begin flashing
only on that specific Mixer’s screen.
