SYSTEM CONFIGURATION - STEREO MODE

Stereo Mode (Single Source)
The X125 and X225 can be configured as a power upgrade for specific zones,
for use with large speaker selectors, and for long parallel speaker runs (outdoor
zones). For a single source connection:
1. Unplug the amplifier.
2. Set the Stereo/Bridge switch to Stereo.
3. Connect the audio line output from a stereo preamplifier or source to the
left and right Secondary input jacks of the amplifier. If the output is only
available as speaker level see "Speaker Level Signal" section below.
4. Connect your speakers to the terminals, observing proper polarity.
5. Restore power to the amplifier. Both channel levels can be adjusted with
the corresponding channel level adjustments.
Dual source connections
The X125 and X225 have dual source capability. If two sources are used,
connect the source you want to take temporary priority to the Primary input
and the other constant source to the Secondary input.
Whenever the primary source becomes active, that signal will take priority
over the distributed audio signal on the secondary line. The signal is still active
on the secondary line but will not be heard, and once the primary audio signal
is muted or turned off the amplifier will automatically switch back to the
secondary audio signal. For dual source connections:
1. Connect the source audio outputs to both Primary and Secondary inputs
as instructed above.
2. Set the switching delay with the Delay Time knob. This adjustment
determines the length of time it takes to switch back to the secondary signal.
For example, if the primary source is a CD changer, increasing the delay time
will prevent a switch back to the secondary source while the disc is changing.
Note: This works with all incoming signals, line level or speaker level.
Speaker Level Signal
If you have a source that is only available as a speaker level signal, connect it to
the Speaker Level Input terminals, using the spring loaded terminal block and
observing proper polarity. Only one set of speaker level inputs can be utilized
and assigned by the selector switch.

Set the switch to Primary or Secondary. This forces the input to act as either
the primary or secondary input.
Only one type of input (speaker or line) should be assigned to each input.
When using the Speaker Level Input, and it is switched to the Secondary
position, the high-level signal will not pass to the Secondary Line RCA output.
