SIGNAL CONNECTORS AND POWER CONTROLS
The Pro15SW’s signal connectors and power controls are located on the unit’s
rear panel, as shown in Figure 4. They function as follows:
NOTE: SEE APPLICATIONS STARTING ON PAGE 10 FOR DETAILED WIRING CONNECTIONS FOR
YOUR APPLICATION.
1. POWER TRIGGER: For external power triggering, use a mini (3.5 mm) plug to connect
the IN jack to a power on/off trigger signal from a home theater sound processor or
receiver. Power on is 3 to 30 Vdc (or Vac). Tip is positive. Power off is 0 Vdc (or Vac).
Use the OUT jack to pass the POWER TRIGGER signal to another Pro15SW. Voltage
will be present on the output jack whenever the amplifier is active. This is indicated
by the green LED on the front panel.
NOTE: FOR A HOME THEATER RECEIVER NOT EQUIPPED WITH A POWER TRIGGER OUTPUT,
CONSIDER USING A NILES 12-VOLT POWER SUPPLY AS A TRIGGER SIGNAL THAT IS
ACTIVATED VIA A SWITCHED AC OUTLET ON THE RECEIVER. SEE FIGURE 9 ON PAGE 14
FOR CONNECTION DETAILS.
2. MOVIE MODE TRIGGER: For external movie/music mode triggering, use a mini (3.5
mm) plug to connect the IN jack to a movie trigger signal from a home theater
surround processor or receiver. The 3 to 30 Vdc (or Vac) signal will set the Pro15SW
to movie mode, while a 0 Vdc (or Vac) signal will keep it in the music mode. Again, tip
is positive. Use the OUT jack to pass the movie trigger signal to another Pro15SW.
