the apparatus.
8. WARNING: The mains plug/appliance coupler is used as a disconnect device, the disconnect device shall remain
1
readily operable.
The lightning ash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of
19.
non-insulated “dangerous voltage” within the product’s enclosure that may be of sufcient magnitude to constitute a
risk of electric shock.
Warning: To reduce the risk of electric shock, do not remove the cover (or back) as there are no user-serviceable
parts inside. Refer servicing to qualied personnel.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important
operating and maintenance instructions in the literature accompanying the appliance.
(Protective earthing terminal) The apparatus should be connected to a mains socket outlet with a protective
20.
earthing connection.
1. Correct Disposal of this product. This marking indicates that this product should not be disposed with other
2
household wastes throughout the EU. To prevent possible harm to the environment or human health from uncontrolled
waste disposal, recycle it responsibly to promote the sustainable reuse of material resources. To return your used

INTRODUCTION
Congratulations on the purchase of your CPD series professional power amplier. Wharfedale Pro CPD ampliers are
the result of many years of experience in the use, design and manufacture of professional audio equipment.
We take great pride in engineering and building every Wharfedale Pro product and wish to thank you for entrusting us
with your sound.
From the time Gilbert Briggs built his rst loudspeaker in 1932, to the present day, Wharfedale have maintained the same
standard of quality in components, workmanship and performance.
Please take the time to read this manual completely in order to ensure that you get the most from your CPD power
amplier.
ABOUT THE CPD SERIES
Suitable for portable sound reinforcement or xed installations, the series feature 4 models that deliver between 350W
and 1300W per channel into a 4 ohm load in a rugged 2U, 19” rack mount enclosure. An advanced transformer power
supply and Class AB/H topology deliver high power with low distortion in a compact and light weight form factor.
A full suite of protection includes thermal, over-current, DC, short circuit protect and power on/off mute. The CPD Series
features XLR inputs and linked outputs with a maximum input level of +22dBu allowing integration with any typical
professional audio system. The variable speed fans keep the amplifier rack quiet when not in use. The CPD series
features 3 different operating modes, parallel, stereo and bridge.
FEATURES
• CPD1000: 350W*2@4Ohms (RMS), 230W*2@8Ohms (RMS), 1000W@4Ohms (BTL)
CPD1600: 620W*2@4Ohms (RMS), 400W*2@8Ohms (RMS), 1600W@4Ohms (BTL)
CPD2600: 1000W*2@4Ohms (RMS), 650W*2@8Ohms (RMS), 2600W@4Ohms (BTL)
CPD3600: 1300W*2@4Ohms (RMS), 870W*2@8Ohms (RMS), 3600W@4Ohms (BTL)
• 2 channels XLR inputs with link outputs
• 3 operation modes (PARALLEL, STEREO and BRIDGE)
• Power, Protect, Signal and Limiter indicators
• Thermal protect, over current protect, DC protect, output short protect, power on/off mute
• Ultra quiet variable speed fans
• Speakon outputs for speakers
• 2U rack mount chassis

channel for BRIDGE mode.
2. XLR link Output: Balanced XLR output to another CPD amplier.
3. Mode Switch: There are 3 switchable operating modes, parallel, stereo and bridge.
4. LIMITER Switch: The internal limiter can prevent signal overload and distortion.
5. SPEAKON Output: For connection to passive loudspeakers.
6. Grounding Terminal: The grounding terminal for the chassis.
7. Mains Power Cord: The unit has a xed power cord, and for the safety, this cord is not allowed to be replaced arbitrarily
by the user.

OPERATING MODE SWITCHES
There are 3 different operating modes switchable for the CPD
series ampliers.
STEREO - Each channel remains independent. The amplifier
may be used for two different signals.
PARALLEL - This setting connects both inputs together. One
signal feeds both channels. Each channel's Gain control and
loudspeaker connection remain independent.
BRIDGE - This setting combines both channels into a single
channel with twice the output power. Use only the rst channel's
input and Gain control. Set the second channel's Gain control at
maximum. The load must be rated for the higher output power.
OUTPUT WIRING
The CPD Series employ Speakon output connectors. Ensure
that only heavy gauge two conductor speaker cables with
professionally wired Speakon connectors are used for
connection from amplier to loudspeaker.
STEREO and PARALLEL Mode- Connect each loudspeaker to
its own channel of the amplier, as shown on the left side of the
Speakon. The Mode switches must be set for Stereo or Parallel
Mode.
BRIDGE Mode- Bridge Mode configures the channel pair to
drive a single audio circuit. The Mode switches must be set for
B
ridge Mode. Connect the load as shown on the left side of CH 1’s
Speakon.
WARNING: Do not use less than 4 ohm load in Bridge Mode!
WARNING: Note polarity of connection for Bridge Mode.
OUTPUT WIRING WARNING: Class 2 wiring shall be used.
For Bridge Mode, class 3 wiring shall be used.
OUTPUT SAFETY WARNING: Make all connections with
amplier turned off. Risk of hazardous energy!

QUICK START GUIDE
1. Make sure that the power switch is set at the OFF position while making connections to and from the power amplier.
2. Connect all devices in the signal path and ensure that each connection is secure.
3. Set all level and gain controls to their minimum.
4. After powering up all other devices rst, turn on the CPD amplier and verify that the POWER LED is illuminated.
5. Turn the amplier volume control up to the 3 o'clock position. (This setting can be adjusted higher or lower, as needed,
after set-up). With source signal present starts to set each gain stage in your signal path, starting at the beginning of
the chain. It is best practice to make overall volume changes with the master fader of your mixing console once the
amplier input trim has been calibrated.
6. When powering down, make sure that the power ampliers are switched off rst.
