The power On/Off power On/Off power On/Off switch turns the mains power completely on and off. The applied mains power voltage should power On/Off
be within -15% and +10% of the selected value. The internal mains fuse value depends on the mains voltage and
is specified on the electronics panel.
The voltage selector voltage selector switch selects between 220/240 V, and 100/120 V. Set this to the correct value BEFORE

applying mains power to the subwoofer. The internal mains fuse is a suitable value for both voltage settings.
The 12 V trigger 12 V trigger is used to turn the subwoofer on and off remotely without having the use the mains power

switch. This may be useful in a large facility where the whole room is powered-up using a single switch.
Equipment can be time-delayed using simple low-voltage circuitry so there is not a mains power surge. Note that
subwoofer's electronics are fully powered on and off with this control, so the startup time is subject to the same
on/off anti-popping muting delays as if the subwoofer had been turned off and on using the main power switch.
There are two modes of operation, which are selected using an internal switch (see picture below):
Remote Power Remote Power
Remote Power Remote Power
Mode Mode Mode Mode
"12 V TURNS OFF"
"12 V TURNS ON"
The factory default mode setting is "12 V TURNS OFF". In both modes and with either applied voltage levels at
the terminals, switching the mains power switch to "OFF" will turn off the subwoofer.
To change the remote power mode to "12V TURNS ON":
• Turn off the subwoofer and disconnect the mains power and signal cables.
• Open the electronics panel (located in the cabinet or remote electronics kit).
• Locate the large switch on the mains power circuit board and move the switch towards the backplate.
• Close the electronics panel and reattach the mains power and signal cables.
• Power up the subwoofer, apply 12V to the remote control terminals, and check that the appropriate lights are
illuminated.

The analog input stages analog input stages analog input stages are all 13 k electronically balanced types on female XLR sockets. An input ground lift analog input stages
switch disconnects pin 1 of all eight input audio grounds from the internal signal ground (note that pin 1 of all
eight input connectors remain connected to each other for both positions of the ground lift switch).
