Dock Selection Tabs
If it is important that a particular OMX1 always
be an “
A
” or a “
B
” unit. As in the case of an
Instructorʼs OMX1 with muting and call-in
capability and a Student OMX1 without,
a Dock Selection Tab can be installed on each
OMX1. The Dock Selection Tab determines
which dock that particular OMX1 will fit into.

OMX1 MIC/Transmitter Features
(contʼd)
Controls and Indicators
(see OMX1 Panel section page 3)
Power Button
The OMX1ʼs Power Button is located on the side in a recessed well. To turn the OMX1 ON, press and release the button; the status
indicator will illuminate. To turn the OMX1 OFF, press and hold the power button for more than three seconds; the status
indicator will extinguish.
Inputs
The OMX1 includes a built-in microphone for use when worn around the neck as a pendant or as a handheld microphone.
Two additional inputs are provided for external devices:
• MIC:
This input is compatible with external lavaliere and headset microphones. The external microphone device must have
a 3.5mm mono plug and be able to operate from a 2.0V DC supply with a 680-ohm series resistance. Using this jack
disables the built-in microphone.
• AUX:
This input will work with either stereo or mono sources. It requires a 3.5 mm stereo or mono plug with output signal levels
of approximately .75V into 3k-ohms. The ultimate level is determined by both the onboard volume control and the ORB35
unit volume trim. Using this jack disables any microphones and is not affected by the Local MIC Mute function.
Volume Control
A thumbwheel volume control located on the top of the OMX1 provides the user with a means of controlling the level of their
program at the ORB35 unit. Care must be taken when adjusting volume levels with the built-in microphone not to cause feedback.
The Orator products are a voice reinforcement system and when the voice program level is set correctly, the speakers will not pick
up their own sound.
Battery Life Status Indicator
The status indicator also provides information on battery life using three signals:
• Continuous Green
– good battery life;
• Flashing Green
– approximately 1 hour of battery life remaining;
• Red
– approximately 10 minutes of battery life remaining.
The OMX1 will turn itself OFF when there is not enough battery life to sustain operation.
Local Microphone Mute
The OMX1 provides a means to mute its built-in microphone (or an external microphone).
• Pressing the power button quickly will toggle the microphone mute function ON and OFF.
• The OMX1 will indicate local mute mode by illuminating the status indicator amber.
NOTE:
Battery level status will be suppressed while in this mode.
• The AUX input is not affected by the local microphone mute mode, and will play normally.
IMPORTANT:
Installation of the Dock Selection Tab is designed to be semi-
permanent. In order to remove, the Tab can be twisted and
then pried (see illustration). If twisted too far, the Tab will
break (with no effect on the unit). Two (2) Dock Selection Tabs
are included per OMX1.
