1 Bass Driver
The Basis 300 and ICS 300 use a 10-inch (254mm)
custom-built long-throw driver with a treated paper cone
and a die-cast aluminum chassis.
2 Handmade Cabinets
Snell cabinets are hand-assembled with exceptional
workmanship to ensure sharp corners and smooth sides.
The wood veneers of the Basis 300 are hand sanded
several times before the final finish is applied. Even the
black finish of the ICS 300 is applied with uncompromis-
ing attention to detail.
3 Bass Reflex Ports
Provide maximum extended bass response. The ports in
each model are specifically tuned to provide the best
possible performance with the driver, cabinet and likely
placement.
4 Bass Level Control
The Bass Level control adjusts the output level of the
subwoofer. It is located for easy access to make it easy
to achieve the correct balance between the subwoofer
and the main speakers. A typical setting for the control
is around the 12 o’clock position.
5 Speaker Level Inputs
The Basis 300/IC-Basis 300 have high-level inputs that
can be used when preamp outputs/power amp inputs
are not available. The speaker output wires are attached
to four binding post connectors. They accept bare wire
or wire with terminals.
6 Low Level Inputs
Use this input when your system has preamp outs and
amplifier inputs.
7 Low Level High Pass Outputs
These outputs provide the signal that goes to the power
amplifier that drives the main speakers in the system.
The signal from these outputs is high pass filtered
(80 Hz, 12 dB/octave) to remove bass sounds.
8 Crossover Frequency Control
This control sets the frequency of the low-pass filter,
and is fully adjustable from 50 to 150Hz. Bass sound
below the frequency set by the control are directed to
the Basis 300 / IC-Basis 300 amplifier and speaker.
9 Bass Mode Switch
Set the switch to INT to use the Basis 300/IC-Basis 300
internal crossovers and the Crossover Frequency and
Bass Level controls. Setting the switch to EXT bypasses
the internal crossover and controls. Use this setting
when the subwoofer is connected to electronics that
controls these functions, such as in THX® systems.
0 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. Use the setting
that produces the smoothest, most consistent sound
through the crossover region.
- Power Mode Switch
When the switch is set to Auto, the amplifier will power 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. When the switch is in the On position the
automatic power on/standby feature is disabled and the
subwoofer amplifier is always on.
= Power Mode Indicator Light (IC-Basis 300 only)
This LED lights when the amplifier is on.
q Power Input Connector
Plug the power cord into this connector and the wall
power outlet.
w Power Switch
This switch turns the power to the subwoofer on and
off. Usually the only time the main power switch should
be turned off is when the subwoofer will not be used for
an extended period of time, such as when you are away
on a vacation.
Warning: To reduce the risk of electric shock, always
switch off the subwoofer and the amplifier and or
receiver when making connections to the subwoofer and
speakers.
e Line Voltage Selector Switch
Set this switch to the power line voltage – 115 V or
230 V – in your location.
Warning: Turn the power switch w of the Basis 300/
IC-Basis 300 before changing the setting of this switch.
