In order to define the PEQ filters, select EQ Setup from the System Setup
menu, Check the box to enable the EQ. Choose which channel you wish to
adjust, select a band and enable its filter, then tune it with the appropriate center
frequency, gain, and Q.
You do not need to have all or even any filters enabled for every channel. The
installer need only make the adjustments to the channels necessary to correct
for the room's interaction. We encourage you to consult with your authorized Classé
dealer to properly calibrate the Parametric EQ function.
NOTE: a discrete IR command or Fkey may be used to toggle the
EQ on and off to easily compare before and after from the listening
position. When the EQ is enabled, EQ appears on the Home page.
The Tone Control may be configured as conventional bass and treble controls
or used as what is sometimes called a tilt control. In either configuration, the
maximum boost and cut is 6.0 dB.
The default setting configures the Tone Control as a Tilt control with low- and
high-frequency 3 dB points at 200 Hz and 2,000 Hz respectively. These values
are user adjustable, allowing customization of the frequency ranges manipulated
by the tilt control. The Tilt control will adjust frequencies above and below
these inflection points by tilting the tonal balance in one direction or the
other, stepping the higher frequency range up or down in 0.5 dB steps while
simultaneously stepping the lower frequency range in the opposite direction,
down or up, leaving the frequencies in between unchanged.
If conventional bass and treble controls are desired, select that option and
choose the frequencies below which the bass control works and above which
the treble control works. The bass and treble controls may be accessed from the
touchscreen (Menu> Tone Control) or by pressing Tone on the remote. Use
the navigation buttons on the remote or the touchscreen buttons to increase
or decrease the level of bass and treble independently. The Tone Control is
activated and deactivated by successive pressing of the TONE button on the
remote, choosing the tone control icon on the Classé app, or selecting and
deselecting the Enable box on the touchscreen. The app makes using the Tone
Control particularly easy, allowing quick selection of Tilt, Bass/Treble and None
while using its virtual volume control knob to adjust levels.
The Delta PRE has two available trigger controls. Each may be programmed
using normal 12 V or "inverse logic" (0 V) settings. The ability to change the
