experimentation with this control is recommended due to system and placement
variables; there is no "best place" to set it other than where it sounds best to you.
Powering Up the Active Subwoofer Section
Your SuperCube subwoofer contains a built-in, active powered subwoofer section
as well as an electronic crossover. Each SuperCube subwoofer must be plugged
into an electrical socket (use an unswitched outlet if possible) 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
SuperCube 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. Please note that if you hear a pop from the speaker when the amp
powers up or powers down, this is normal. The red LED on the back panel will
light up when a signal is sensed and the amplifier turns on. Please note that after
the cessation of a signal, it may take up to an hour for the amplifier to actually tum
off. In some installations where radio frequency (RF) remotes is present in the area
the red light may remain on. This is nothing to be worried about as the amp will be
in low idle mode which uses virtually no power.
To prevent accidental damage to your subwoofer from overdriving the
system, the subwoofer features an internal overload protection circuit,
which will turn the subwoofer off or down when overdriven or over-
heated and will then resume normal operation after a few minutes.
Very Important: Setting Channel Balance
and Bass Management Systems
I
Dolby Digital and DTS 5.1 (6.1, 7.1) systems and decoders have a critical
channel balancing procedure for the left and right front speakers, center channel,
rears and subwoofer (if it is hooked up through the "LFE or Sub Out" low-level
connection) which must be followed if the system is to perform properly. We
have spoken with many system users with problems relating to the overall sound
of their system which could be clearly traced back to improper system balance.
In fact, many users never realize that there is a system balance procedure to
be followed.
Also note that Dolby Digital and DTS 5.1 (6.1,7.1) systems and decoders have
bass management systems (systems which direct the bass to the various channels)
which vary from unit to unit. This bass management system must also be properly
adjusted. We have spoken with many system users with problems relating to the
overall sound of their system which could be clearly traced back to improper
bass management. In fact, many users never realize that there is a bass manage-
ment procedure to be followed.
