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
RCC600-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 RCC600 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
to be raised to achieve the previous volume levels.
If your normal listening position is located in a null, then the only way to truly even out the null
is by either moving the subwoofer location to change the room modes that are stimulated OR
install a distributed bass system.
Distributed bass uses multiple subwoofers in different
locations in order to stimulate more of the room modes. It has been shown that this type of
system mitigates Eigen-modes and provides a more uniform response to a wider listening
area. Each RCC600-SA has the capability for running two RCC600-SM, or two RCC600-FS.
