In this configuration, the Mode switch is set to “Stereo” for
stereo operation. Connect the line out jacks from a stereo
preamplifier or source to the Line 2 Input jacks of your MI4
Power Amplifier. Then connect your speakers to the output
Binding Post observing proper polarity(You can check
“OUTPUT” on Page 4 for reference about the polarity).

In this configuration, the Mode switch is set to “Bridged” for
Bridged operation. Connect the line out jacks from a stereo
preamplifier or source to the Line 2 Input jacks of your MI4
Power Amplifier. Then connect your single mono speaker to
the output Binding Post observing proper polarity(You can
check “OUTPUT” on Page 4 for reference about the polarity).
To Mono Speaker
The audio output of a local source, such as MP3 Player, CD,
Television, computer, etc., is connected to the MI4 Power
Amplifier via the Line 1 Input, and whenever the local source is
active its signal will take priority over the distributed audio
signal present at Line 2. However, the distributed audio signal
will still be present at the Line 2 Input. In this circumstance the
audio output of the local source will be heard via the MI4 Power
Amplifier. Once the local source is turned off or muted, the MI4
Power Amplifier will automatically switch back to the
distributed audio system as an audio source, assuming the
local source remains inactive. The delay time is 12 seconds
when switch back to the normal source will occur. This set up
assumes all incoming signals are at line level and not at
speaker level.

If the Whole House Distributed Audio was only available as a
speaker level signal you could connect it to the “Speaker In”
connections and set the switch which is on the right side of
“Line 1" Input RCA connectors to the “Line 2" position or toward
to the left hand position of the switch. The MI4 Power Amplifier
will no longer be able to pass the Whole House Distributed
Audio to another zone via the Line 2 Output.
In the application shown below, a distributed audio system is
connected to the MI4 Power Amplifier as a local zone amplifier
via the Line 2 Input. Normally the distributed audio system will
be the audio source for the MI4 Power Amplifier. The
distributed audio can be passed on to be used by additional
zones or sub zones in the distributed system via the Line 2
Output.
