5. HIGH PASS Frequency adjustment with ON/OFF switch: This feature allows you to run

R/L loudspeaker wires (RCA line level wires) from an amp/receiver/processor into the
SWA-500M and then back to the main audio amplifier to the R/L loudspeakers. When
the HIGH PASS Frequency switch is engaged, you can then control the frequencies
to those R/L speakers via the front control knob. Use the HIGH PASS control to set
the high-pass crossover frequency from 60 to 160 Hz (according to your loudspeaker
manufacturer’s recommendation) to drive a satellite loudspeaker system amplifier
from the line-level AUDIO OUT jacks. To activate the filtered signals, set the ON/OFF
switch to ON.

6. The MODE indicator (on the far left) shows which power mode is active, as set by the

(Auto) POWER switch: Green is ON; Red is STANDBY.

SIGNAL CONNECTORS AND POWER CONTROLS

The SWA-500M’s signal connectors and power controls are located on the unit’s rear panel, as
shown in

Figure 7. The controls function as follows:

NOTE: SEE

APPLICATIONS STARTING ON PAGE 11 FOR DETAILED WIRING CONNECTIONS FOR

YOUR APPLICATION.

1. 12V POWER TRIGGER: The SWA-500M can be turned on or off using the power switch

on the back panel or it can turn on or off automatically via the 12V 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. The back-panel
switch overrides this function and must be in the on position for the 12V power trigger
to work. The input accepts (AC or DC) control signals with power ranging from 3 Volts
to 30 Volts. Tip is positive. Power off is 0 Volts DC (or AC). You can use the OUT jack
to pass the POWER TRIGGER signal to another SWA-500M amplifier or other trigger-
activated device, such as motorized speakers or rear effects speaker’s dipole/bipole
mode. Voltage will be present on the output jack whenever the amplifier is active. This
is indicated by the green LED on the front panel.
