Connect the + (positive) output post of the amplifier to the + (positive)
input terminal of the appropriate loudspeaker. Connect a – (negative or
black) output post of the amplifier to the – (negative or black) input ter-
minal of the appropriate loudspeaker. Take care to maintain this proper
polarity throughout the system.
Caution! DO NOT OVERTIGHTEN the binding posts on your amplifier! The
unique design of these posts gives far more leverage than traditional
posts. You will achieve tight, high contact pressure connections with
only modest finger-tightening, and without having to resort to special
tools.
2 RCA Inputs
These audio inputs normally accept the subwoofer output signals from
the system’s Surround processor. If two inputs are connected, they will be
summed and amplified as a single channel.
Connect the appropriate outputs of the SW-1 to this input, using a high
quality audio cable.
3 DC Trigger In and Out
These 12V trigger jacks provide compatibility with a wide range of prod-
ucts to facilitate remote turn-on and turn-off in systems. These

” (3.5
mm) “mini-jacks” allow other components to bring the SW-1 in and out
of standby. Two such mini-jacks are provided to allow “daisy-chaining” of
this turn-on signal with other components, including additional amplifiers.
The remote trigger input will be operated by any positive-polarity DC
signal between 3–20 volts (only a few milliamps are required), with tip po-
larity as shown below:
Remote turn-on
tip polarity
+ –
Input Signal: 3-20 volts @ less than 10 mA
Output Signal: 12 volts @ 100 mA
When connected to AC mains power, with no trigger plug inserted, the
SW-1 is normally fully On. Employing a DC Trigger Input allows you to
place the amplifier into standby. When the voltage transitions from high to
low (off), the unit will go into standby.
The 12V Trigger Output jack is driven to a “high” state of 12 volts a few
seconds after the SW-1 is turned on, and can source as much as 100 mA
of current at 12 volts. This signal may be used in turn to control other
components, such as additional Wisdom Audio SA-series amplifiers.
