The Front Panel
The iconic front glass panel of the MX123 provides
knobs and buttons to control the unit as well as an
informational display and LED status lights that
display the current mode.
Standby On
The red STANDBY ON button toggles the MX123
between on and standby mode. The STANDBY
button will only work with AC Power connected
(see “AC Power” on page 10). When the unit is
in standby mode, it can also be toggled on/off using
the Remote Control or the browser interface.
If Zone2 or 3 is on, those Zones will continue to be
on. Those Zones can be toggled on and off using the
ZONE ON / OFF buttons. See “Zone On/Off” on
page 13.
The Input Knob
The Input Knob can be turned clockwise or
counterclockwise to scroll through all the Inputs
that are enabled in Setup. All Inputs are available by
default.
The Volume Knob
Turn this knob clockwise to raise the volume and
go the other way to make it quieter. A maximum
volume of 70% is the factory default for each zone.
The value of the Volume Limit can be set in the
General Setup section for each Zone. Options are
60, 70, or 80 percent. You can defeat the Volume
limit by choosing the “Off” option. A maximum
volume prevents the MX123 from accidently
sending higher signals than your situation permits.
The Arrow and Enter Buttons
These buttons are used to navigate menu screens
and selections in the Trim menus. The arrows allow
scrolling up , down , left , and right when
those are menu choices. The ENTER button accepts
an option and the left button returns to the
previous menu when a value is not being selected. If
a value needs to be selected, the left and right
arrows will scroll through the options. Push ENTER
to select the chosen value.
Status
Repeated presses of the Front Panel or Remote
Control STATUS Push-button will step through the
type of incoming Audio Signal, the selected Input
(along with type of A/V Connection) and audio
processing mode.
