Crossover adjustment
We recommend that you set your home
theater processor's crossover to 80 Hz,
and set the channels that use the Cinema
Ribbon Trio loudspeakers to "small."
• Your subwoofer receives frequencies
below 80 Hz, from all loudspeakers
whose size is set to small, in addition to
the LFE channel:
• All loudspeakers set to small, receive
frequencies above 80 Hz.
• Set your subwoofer's own crossover
control (if it has one) to maximum
frequency or bypassed mode. (If it is set
lower than the 80 Hz, there would be a
hole in the mid-bass, and bass informa-
tion would be missing.)
The acoustic summation of the
subwoofer output and the Cinema Ribbon
Trio output produces a fl at frequency
response.
NOTE: Dolby Digital and DTS modes
are designed especially for complete
systems with front, center, and surround
loudspeakers and subwoofers. You need
all of the loudspeakers to get the best
per for mance from your Home Theater. If
you do not have a subwoofer connected,
you will be missing the 5.1 LFE (low
frequency effects) information.
Break-in period
Like many high performance automo-
biles, the Cinema Ribbon Trio loudspeak-
ers perform at their best after an initial
break-in period. A minimum of 20 hours
is recommended prior to performing
critical listening, however the speakers
will sound their best after a period of 300
to 400 hours. During this time, the driver
suspensions and ribbon structure will
relax into their operating design positions
and give optimum performance.
To facilitate break-in during the initial
20 hours, it is recommended that you
play material with a wide dynamic range
at louder volumes – such as your favorite
rock and roll album (that is if your family
or neighbors can stand it).
It is important that your amplifi er
must supply good clean power,
and not run into distortion. Amplifi er
distortion due to clipping, causes
high-frequency output components that
can damage loudspeakers. Even a 100
watt amplifi er running into clipping can
damage loudspeakers rated at 400 watts
or more.
NOTE: If your processor or preamplifi er
does not have a crossover control, you
might need an external active crossover
to split the audio signal into a low-pass
range for the subwoofer, and a high-
pass range for the Cinema Ribbon Trios.
(Sunfi re subwoofers have their own
crossover controls with line-level high-
pass outputs that can be used to power
an amplifi er connected to Cinema Ribbon
Trio loudspeakers.)
