Figure 08- Power Control (Trigger) Mini Plug; Figure 09- Data Out Mini Plug; Power Control (Trigger) Outputs; Analog Audio Output - McIntosh MX123 Owner's Manual

At this stage, the connection from the MX123 to the
various amplifiers and powered speakers should be
made using quality balanced XLR cables.

Power Control (Trigger) Outputs

The MX123 has two Power Control Outputs or
Triggers. Power Control enables power on/off
signals to go to connected components so that other
components can automatically power on (or off) as
called for by the MX123. For example, you may
want a DVD player and a certain monitor to power
on when HDMI 1 Input is selected, or you may want
all components to power off when powering off the
MX123. For Setup instructions see "General Setup"
on page 24.
Connect components using a 3.5mm stereo mini
plug. See Figure 08.

Analog Audio Output

Two additional Zones labeled ZONE2 and ZONE3
can be fed analog signals using a pair of RCA
cables for each Zone. The jacks are located under
ANALOG AUDIO OUT on the right side of the rear
of the MX123.

Data Out

The MX123 will convert IR Remote Control data
to share with McIntosh components connected to
the Data Ports. This will allow units that are out of
range of an IR signal to receive commands.
To connect a McIntosh unit to a Data Port, use a
3.5mm stereo mini phone plug cable. See Figure 09.
