Non-THX Low Level Connection
When connecting the ICS Sub 24 mk3 to
electronics that does not have a THX control
system, use the low level (also called line level)
connections whenever possible. Even if you
do not have a separate preamp and power
amp, many receivers and integrated ampli-
fiers include ”Preamp Out“ and ”Amplifier In“
connectors.
When using the low level connections, the
signal from the High Pass Outputs that is
returned to your amplifier is high pass filtered
to remove sound below 80Hz. This is a non-
adjustable filter. It is not affected by the setting of the Crossover control. See the Fine Tuning section of this manual
for more information.
Subwoofer Output Connection
Some electronics have monophonic subwoofer
outputs. If your system has this type of an output
it can be connected to either of the low level
inputs. The benefit of using this type of connec-
tion instead of using the THX setting is that it
does not bypass the controls of the ICS Sub24
mk3.. You can still use the level control to adjust
the output of the subwoofer. Typically such out-
puts are low pass filtered, so you should set the
ICS Sub 24 mk3 crossover control to it’s highest
setting to minimize its effect. If listening test show there is an excess of mid-bass sound you may want to use a lower
crossover control setting. See the “Fine-Tuning Your Subwoofer” section for more information.
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.
THX® Connection
Use this setup when the ICS Sub 24 mk3 is con-
nected to a receiver or surround sound controller
that has a built-in THX control system. This input
bypasses
ALL
the crossover and control circuitry
of the ICS Sub 24 mk3.
