Installation guide
00
Baffle
- The RCC 300 Subwoofer Module
is
installed
in
a wall that has an air
volume
of
~1.4
ft3.
CLOSED
BOX
- The RCC 300 Subwoofer Module
is
installed
in
an
Artison In-Wall
Pre-Build Box or is the RCC 300 Freestanding Subwoofer.
IMPORTANT: In an
installation
of
two
RCC300-SM's
that
are
being
powered
by
one
RCC300-SA,
both
Subwoofer
Modules
need
to
be
in
either
Pre-Build
Boxes
or
be in
Infinite
Baffles.
You
cannot
connect
two
RCC 300
Subwoofer
Modules
that
are in
different
environments
to
the
same
RCC 300
Subwoofer
Amplifier.
2. PHASE - Comes from the factory set at 0°. The phase
of
the subwoofer can be adjusted
to fine tune the signal coincidence
of
the subwoofer and the lower frequencies
of
your LCR
Speakers. Adjust the phase, listening for an increase
in
mid bass
in
the crossover region.
A pink-noise generator or
an
RTA (Real-time Analyzer) can further analyze your
installation.
3.
LOW
PASS - This
is
the crossover frequency setting
of
the Low Pass Filter. The
RCC300-SA comes from the factory with the 80Hz setting that is recommended for use
with the Artison LCR speakers. If used
in
conjunction with any other speakers consult with
the manufacturer for the correct setting for the integration
of
the subwoofer with the
satellites.
4. SLOPE - Select either 12 dB/octave or 24 dB/octave for the slope
of
the Low Pass Filter
based on the correct frequency response at the crossover point. This can be done by
measurement or simply listening to the system. A proper crossover will not have
an
apparent "hole"
in
the response nor will it exhibit the "bloated" mid bass sound that a peak
will create. Again,
an
RTA can come
in
handy during this part
of
the set up.
EQ MODES -
Automatic
Room
Mode
Correction
(ARMC)
The amplifier comes from the factory set to BYPASS. This setting produces a flat frequency
response at the subwoofer module.
In
some cases your room response may benefit from
ARMC. Eigen-modes, also known as room modes, exist
in
all rooms. These room modes are
an
interaction between the listening room itself, the location
of
the subwoofer, and the low
frequency wavelengths being on the same order as the room dimensions. This interaction
causes peak and null energy areas
in
your listening room which differ depending
on
the room
and the subwoofer location.
The ARMC program was designed to send a series
of
tones thru the RCC300 and then
analyze the system response at the microphone position. The program then reduces the level
of
the frequency bands that have energy peaks caused by the room modes. As a by product,
after the ARMC process has been completed the overall subwoofer amplifier gain may need
