All home audio systems are aected by room characteristics. Sound reections
and sound absorption can create dramatic variations in the performance of your
system, particularly in the lower frequencies. e Delta PRE features a system
of Parametric EQ lters which, in the hands of an experienced acoustician, can
help optimize the performance of your system.
Bass management allows one or two subwoofers to be added to augment
frequencies where the response from the Left and Right speakers may tend to
cancel each other. Together, these digital domain tools help deliver smooth and
accurate low frequency performance. Lastly, a sophisticated and exible digital
domain Tone/Tilt Control can be used to tweak the tonal balance of individual
recordings.

Unpacking and Placement
We have taken all precautions, and made every eort to make the Delta PRE
simple and straightforward to install and use. Still, we recommend that you
take a few minutes to review this manual. Even if you are having the preamp/
processor professionally installed, you will want to know how to eciently
operate it to its potential.
e Delta PRE menu system includes features that allow a great deal of netuning. Still, we have no way to evaluate outside variables such as the acoustical
characteristics of your listening space and the associated equipment of your
audio system. erefore, it is up to you to make the nal audio adjustments for
the optimum performance of your system.
unpacking your
Delta PRE
Important!
Delta PRE placement
considerations
Carefully unpack the Delta PRE Stereo Preamp/Processor. Do not forget to
remove all accessories from the carton.
Keep all packing materials. Transporting the Delta PRE without
using the packaging specifically designed for it may result in
damage that is not covered under the warranty.
Before installing your Delta PRE, be sure to read the following placement
suggestions.
• Do not place the Delta PRE directly on the top surface of a
conventional power amplier or any other heat source. Also keep the
unit out of direct sunlight.
• Place the Delta PRE so that the IR window on the front panel is
clearly visible and not blocked.
• Position
both visibility and use. e preamp/processor is the hub for all other
component connections and generally your primary interaction point.
In addition, by placing the unit close to the other system components,
you minimize the cable lengths and hence reduce the amount of noise
that is introduced into the system through the cabling.
• Leave
connecting cables. We suggest six inches (15 cm) of free space to allow
cables sucient room to bend without crimping or undue strain
• Allow at least three inches (7.5 cm) of clearance above and to each
side of the Delta PRE for ventilation. Do not obstruct the area
around the unit so that excess heat can dissipate through normal air
circulation.
the Delta PRE in a central and convenient location for
adequate clearance behind the Delta PRE for the AC cord and
.
Important!
6
Obey all placement considerations. Not obeying the
placement considerations may result in damage that is not
covered under the warranty.
warm-up/break-in period Your new Classé preamp/processor delivers outstanding performance
immediately. However, you can expect to hear subtle improvements as it reaches
normal operating temperatures and breaks-in.
In our experience, you can expect the greatest changes within the rst 72 hours.
After initial break-in, you’ll enjoy consistent performance levels for years to
come.
operating voltage
Important!
e operating voltage of your Delta PRE is specied on the rear panel label that
also includes its serial number. .
Attempting to operate your Delta PRE from an incorrect AC
voltage source may cause irreparable damage which may not
be covered by your warranty.
If you are not planning to use the preamp/processor for an extended period of
time, for example due to vacation or other travel, we suggest that you disconnect
it from AC power.
Make certain that the Delta PRE is in Standby prior to disconnecting it.
Physically disconnect any and all valuable electronics from AC power during
electrical storms. A lightning strike anywhere near your home can generate a
tremendous surge on the AC mains that can jump across a simple power switch.
A surge from a lightning strike, which may be many thousands of volts, can
cause serious damage to any piece of electronics, no matter how well designed
and protected.

Front Panel
e front panel of the Delta PRE is shown above. e numbers in the drawing
refer to the descriptions that follow.
1 Standby/On Button and Status Indicator LED
Pressing the Standby button puts the Delta PRE into standby mode – a
low-power state which leaves the preamp/processor and outputs inactive
but still allows the unit to respond to system commands via any of the
supported control protocols (IR input, LAN, CAN-Bus or RS-232)*.
If the unit is already in Standby mode, pressing the Standby button fully
powers up the unit.
• LED On (Red) – the Delta PRE is in Standby mode.
• LED turns green, then white – the Delta PRE is in the process of
power-up initialization.
• LED On (white), indicates the unit is in the operate mode.
• LED Flashing (blue), indicates the unit is updating rmware.
• LED Flashing (red), indicates a problem during startup.
LED O – the Delta PRE is not getting AC power.
•
*See section on Advanced Settings: Wake-on-Network must be enabled
to allow controllers to wake the unit from Standby.
2 Touchscreen
e front panel touchscreen is used for day-to-day operation of the Delta
PRE. It is also used for setup and to display useful information as required.
Touch the screen anywhere on this Home page to access sources.
3 Menu On/Off Button
Press once to call up the main page of the menu system. Press the Menu
button again to revert to the Home page.
e menu system gives you control over operational details including:
system setup options, various display options and custom installation
capabilities so that the Delta PRE integrates smoothly into the most
complex systems. For more information, see the Menu System later in this
manual.

4 IR Window
e location of the IR (infrared) receiver for the remote control is behind
this window. In most cases, there must be a clear path between the IR
window and the remote control in order for the Delta PRE to acknowledge
the remote control commands.
If the IR window is not in view, for example if the unit is placed in a
cabinet or closet, then the rear panel IR input can be utilized for remote
control. For more details about this option, see the IR input description in
the Rear Panel section found later in this manual.
5 USB Host Connector
e front panel USB connector allows the Delta PRE to work with
Apple’s portable media devices such as iPad™, iPod® and iPhone® which
require this type of connection. e front panel USB connector accepts
digital audio from these devices (up to 96 kHz) and provides power for
recharging them. Limited control is also available for these devices using
the navigation keys on the Delta PRE remote control.
e front panel USB connector is also used to load rmware updates.
When updates are posted in the software downloads section of the Classé
web site, they may be loaded onto a USB stick and plugged into the front
panel of the Delta PRE. More information on this can be found in the
Firmware Updates section of this manual.
6 Headphone Jack
e 1/4
” (6.35mm) Headphone Jack accommodates stereo headphones.
Inserting a headphone plug mutes the main audio outputs.
7 Volume Control Knob
e large rotary knob on the right side of the front panel controls the
system volume level. It is also used for adjustments such as balance, input
oset and levels for the EQ and Tone Control.
The volume knob increases and decreases volume in precise 0.25 dB
increments throughout most of the volume range. At extremely low
volume, the step size is increased somewhat to facilitate moving between
extremely low and normal listening levels. e volume range is from
-93.00 dB to +14.00 dB.
e volume control expresses the degree of attenuation or amplication
being applied to the incoming signal. erefore, a setting of -23.00
indicates that the signal is being attenuated by 23.00 dB.
Most stepped attenuators oer too few steps, causing the listener to
choose a level that is a bit too soft or too loud, not just right. e volume
display on the touchscreen reads in 0.25 dB increments , thereby closely
approximating a continuous volume control, allowing the desired level to
be selected precisely as required for critical listening.
A volume setting of 0.00 indicates that no attenuation or amplication is
being applied. is is the setting used for the Pass-ru mode explained in
the Source Setup description in the Menu System section of this manual.

1 Digital Audio Input - USB
e Delta PRE supports PCM digital audio sources up to 32-bit/384kHz
and DSD at native rates up to 256 (requires esycon/Classé driver for
Windows) and as DoP (DSD over PCM) at rates up to 128 via USB. e
rear panel USB Device connector mates with a USB Host such as a PC or
Mac.
Volume control changes made on your USB source will adjust volume in the
analog domain in the Delta PRE, which oers the highest performance. e
alternative, which is to adjust volume in the digital domain, causes loss of
resolution. Attentuation in the digital domain involves using fewer bits, so we
avoid it wherever possible
2 Digital Audio Input - AES/EBU
e Delta PRE provides an XLR type connector for digital audio
connections from source components such as CD players tted with this
professional-standard output. ese inputs accept PCM data streams up to
32-bits long and up to 192 kHz sampling frequency. We recommend using
cables that are optimized for digital audio signal transfer and that carry a
110Ω impedance rating. Your Classé dealer can help you with proper cable
selections.
3 Digital Audio Inputs - Coaxial
e Delta PRE supports three digital audio inputs, with SPDIF connectors
labeled COAX1 to COAX3. ese inputs accept PCM data streams up to
32-bits long and up to 192 kHz sampling frequency. We recommend using

10
75Ω impedance rating. Your Classé dealer can help you with proper cable
selections.
4 Digital Audio Inputs - Optical
e Delta PRE supports three digital audio inputs, with optical TOSlink
connectors labeled OPT1 to OPT3. ese inputs accept PCM data
streams up to 32-bits long and up to 192 kHz sampling frequency*. We
recommend using cables that are optimized for digital audio signal transfer.
Your Classé dealer can help you with proper cable selections.
*NOTE: e bandwidth limits of TOSlink™ components are very
much strained at a 192 kHz sampling frequency. For that reason
you may want to limit signals using the TOSlink™ connections to a
maximum rate of 96 kHz.
5 Analog Audio Inputs - Single-Ended
e Delta PRE supports 2pr of RCA type connectors for single-ended linelevel analog sources. ey are labeled R3/L3 and R4/L4.

NOTE: is input conforms to the AES (Audio Engineering
Society) “pin 2 = hot” convention. e pin assignments of these
XLR-type female output connectors are:
TM
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
Verify that the source components are compliant with this
convention (Classé components are compliant). If not compliant,
contact your Classé dealer for assistance.
e XLR R2/L2 connectors may be assigned as a phono input. See the
section on Phono Setup.
NOTE: e Balanced and Single-Ended 2-channel analog
audio inputs can be set for either digital bypass mode (all DSP
processing switched o) or converted to digital format to allow bass
management, tone control and/or equalization. If no processing is
applied, analog signals remain in the analog domain, even if not
specically set to digital bypass.
7 IR Input
Use the IR input when the front panel IR window does not have a clear
line-of-sight with the remote control, for instance, when the Delta PRE is
installed in a cabinet. Attach this input to an infrared repeater system to
route signals from the remote control to the Delta PRE via a mono minijack (3.5mm phono).
11
e list of available IR command codes can also be used in macros for
sophisticated remote control systems, facilitating the control of the
Delta PRE in the larger context of the complete system.
8 IR Output
Use the IR output to pass IR commands from an external IR transmitter
through the Delta PRE to another component, when necessary. e
output uses a mono mini-jack (3.5mm phono) with the same properties as
the diagram in the previous section.
9 Trigger Outputs
e Delta PRE supports two trigger outputs, with mono mini-jacks
(3.5mm phono) labeled OUT1 and OUT2. Each trigger outputs a 12V
DC signal at 100 mA and each can be controlled individually. Use these
outputs to control other system components such as ampliers and
window blinds. Refer to the DC Triggers description in the Menu System
section for more details.
10 RS-232 Port
e primary purpose of the RS-232 port is to support the use of external
commands to allow remote control of the Delta PRE by such systems as
