Crossover Low-Pass Filter Control
This control sets the frequency of the low-pass filter,
and is fully adjustable from 50 to 150Hz. Bass sound
below the selected setting are directed to the ICS Sub 24
mk3 amplifier and speaker.
2
Low Level Inputs
Use this input when your system has preamp outs and
amplifier inputs.
3
Low Level High Pass Outputs
When the low level inputs are used, these outputs
provide the signal that goes to the power amplifier in
the system. The signal from these outputs is high pass
filtered to remove bass sound below 80 Hz.
4
Bass Management Switch
When the ICS Sub 24 mk3 is used with receivers or sur-
round sound controllers that have built-in THX control
systems, set this switch to “THX/External”. This setting
bypasses the low pass filter and
ALL
the crossover con-
trols of the ICS Sub 24 mk3. To use the subwoofer’s low
pass filtering and front panel gain control set this switch
to “Internal”.

Speaker Level Inputs
The ICS Sub 24 mk3 also has high-level inputs that can
be used when preamp outputs/power amp inputs are
not available. The 5-way gold-plated terminals accept
spade lugs to 5/16 inch, pins, banana plugs, and up to
12-gauge bare wire. When main speakers are connected
to the speaker level

Bass Level Control
The Bass Level control adjusts the sound level output
of the ICS Sub 24 mk3. It is located on the front of the
cabinet, behind the grille.
To access the control grasp the top and bottom
edges of the grill and pull it straight off the front of the
cabinet. A typical setting for the control is around the
12 o’clock position.

Bass Drivers
The ICS Sub24 mk3 uses two 12-inch (305mm) custom-
built long-throw drivers, a coated paper cone, santoprene
surround, and a die-cast aluminum chassis.
8
Phase Switch
Determines whether the subwoofer adds or cancels in
the crossover region. The proper setting changes based
upon the current location of the speaker.
9
Turn On Mode
This switch controls the automatic power up function.
When the switch is set to Auto On, the amplifier will pow-
er up when it senses an input signal. If no input signal is
present, the amplifier switches to low power standby mode
after 8-10 minutes. The LED next to the Power switch lights
green when the amplifier is on, and yellow when it is in
standby mode. Put the switch in the Always On position to
defeat the automatic power down feature.

Power Switch
The main power switch is located next to the power cord
socket. Push in the top side of the switch to turn on the
main power to the system. Push in the bottom side to
turn off the main power. Usually the only time the main
power switch should be turned off is when the sub-
woofer will not be used for an extended period of time,
such as when you are away on a vacation.
