In order to dene the PEQ lters, 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 lter, then tune it with the appropriate center

frequency, gain, and Q.

You do not need to have all or even any lters enabled for every channel. e

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 o to easily compare before and after from the listening

position. When the EQ is enabled, EQ appears on the Home page.

Tone Control Setup e Tone Control may be congured as conventional bass and treble controls

or used as what is sometimes called a tilt control. In either conguration, the

maximum boost and cut is 6.0 dB.

e default setting congures the Tone Control as a Tilt control with low- and

high-frequency 3 dB points at 200 Hz and 2,000 Hz respectively. ese values

are user adjustable, allowing customization of the frequency ranges manipulated

by the tilt control. e Tilt control will adjust frequencies above and below

these inection 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. e 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. e 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. e 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.

DC Triggers e Delta PRE has two available trigger controls. Each may be programmed

using normal 12 V or “inverse logic” (0 V) settings. e ability to change the
