5 - Using the ARC 2 Plug-In
4 2
ARC System 2
AUDYSSEY FLAT: the system will correct the frequency response so
that the final response will be very close to flat. However, the system
will not extend the low frequency response of the speakers beyond
their limits to avoid possible damage and excessive distortion. In fact,
the AUDYSSEY Flat curve corrects the response to flat from the low
frequency cutoff point that the ARC 2 has determined to the upper fre-
quency limit of the tweeters.
AUDYSSEY HF Roll-off 1: this should be selected if you feel that FLAT
sounds excessively bright in your room. The AUDYSSEY High Frequency
Roll-off 1 curve introduces a slight roll-off at high frequencies that
accounts for the balance between direct and reflected sound in small to
medium-size rooms.
Both AUDYSSEY FLAT and AUDYSSEY HF Roll-off 1 target curves are
also available with the Midrange Compensation, “Mid Comp,” option.
AUDYSSEY MIDRANGE COMPENSATION (Mid Comp) is sometimes neces-
sary to correct the directivity differences that often occur in that frequency
range due to crossover circuitry or horn-loaded speakers. Start listening
to the corrected systems without Mid Comp, allow yourself to get used to
the “new sound” of your studio, and then try the Mid Comp option. Listen
to your favorite music, and then judge which AUDYSSEY Target Curve
sounds more natural on your speakers and in your room environment.
CUSTOM 1/4: these user definable curves reflect the settings of the cor-
responding ones in the EDIT page of the plug-in.
NOTE: switching between target curves takes a few seconds the first time
any curve is loaded. This is necessary for ARC 2 to load the correspond-
ing file (figure 5.5). This only happens the first time the curve is loaded or
when a modification is applied to one of the Custom 1-4. Switching becomes
instantaneous afterwards allowing for on-the-fly, seamless switching.
