Your Definitive Technology ProSub 60 subwoofer is equipped with a full
complement of operating controls to ensure complete flexibility and maximum
performance in any installation. Most of them basically are the “set and for-
get” type, although occasionally certain controls will require minor adjust-
ments.
Gain Control
On the back panel of your subwoofer is a gain (volume) control. This control
is used to raise or lower the output level of your subwoofer in relation to the
other speakers in your system.
Low Pass Filter
Your subwoofer’s back panel features a continuously variable low pass filter.
This filter is continuously variable between 40 and 150 Hz. This low pass fil-
ter control is used to obtain the optimum transition between the subwoofer
and your main speakers. This control should be set by ear for best perfor-
mance in your room. Set it to where it sounds best to you. If you are running
your main speakers full range, we would generally recommend setting the
low pass filter fairly low (40-70 Hz).
When using the ProSub 60 with
Definitive ProMonitors, please consult the instruction manual section
“Using the ProSub 60 with Definitive ProMonitors.”
Your subwoofer contains a built-in, active powered subwoofer section as
well as an electronic crossover and so each subwoofer must be plugged into an
electrical socket of the appropriate voltage (as indicated on the back of your
unit) using the plug on the end of the black cord attached to the electronics
module on the back of the loudspeaker
. The subwoofer has a special circuit
which automatically turns the powered subwoofer section on when a signal is
fed to the loudspeaker and does not require an on-off switch. The red LED on
the back panel will light up when a signal is sensed and the amplifier turns on.
It will automatically turn off a little while after the signal is discontinued.
The ProSub 60 has a special circuit which automatically turns the powered
subwoofer section on when a signal is fed to the loudspeaker and does not
require an on/off switch. We suggest plugging the ProSub 60 into a circuit
which is on all the time and not into a switched outlet. When the ProSub 60
is plugged into a circuit and receives AC current, initially you will hear a rela-
tively loud pop which is completely normal as the system first activates itself
to stand-by mode. Then, when a program signal is fed to the speaker it will
fully activate itself with a lower level pop which is normal. If you unplug the
speaker or turn off the AC current going to it, it will reactivate itself with a
pop when AC current is restored, which is normal.
Please note that after the cessation of a signal, it may take up to an hour
for the amplifier to actually turn off from active to standby mode.
In some
instances, because of RF presence in your area, the red LEDs may not turn off.
However, this is nothing to be concerned about as the amplifiers draw almost no
power when they are idling.
