EURO (230 VAC) MODEL: Connect 
the linecord to the subwoofer before 
connecting the other end to a 230 Volt, 
50/60 Hz AC outlet. The outlet must 
have a cir cuit rating of 8 amps or more.

Never plug the Euro (230 VAC) 
model subwoofer directly into 120-
130 Volts AC.

11. Power Switch

The power switch is a CE requirement 
for international shipments. Leave it 
switched on at all times for normal 
operation.

After a period of inactivity (i.e. with 
no input signal), the subwoofer will 
automatically turn itself to Standby 
mode, where it is effectively off. It can 
however, turn back on automatically 
when an input signal is applied, if a       
12 VDC trigger voltage is applied to the 
Trigger inputs, or if the Start button is 
pressed.

12.Start button

Press this once to enter the Auto EQ 
mode (if the sub is out of Standby 
mode). Press and hold down for     

several seconds to enter the Manual 
EQ mode. See page 12 for more 
details on this and the following EQ 
controls.

13.Microphone Input

This is where you plug in the supplied 
linear measurement microphone when 
you want to use the Auto EQ mode.

14.LED display

These LEDs are used during the Auto 
EQ and Manual EQ procedures.

15.Equalizer Authority

This control's primary purpose is to 
adjust the EQ Authority. During normal 
listening, you can adjust the overall EQ 
from none (ccw, 0%), to fully equalized 
(cw, 100%). For example, if your Þ rst 
band has a 6 dB boost, setting this 
control to 50% would make it boost 
only 3 dB.

This control is also used during the 
Manual EQ mode to adjust each of the 
four internal EQ bands, and allow you 
to add "color" to the sound as desired.
