Wharfedale Pro DP-4035i
4-CHANNELS OF POWER. PERFECT FOR FIXED INSTALL.
With the DNA from our DP series, the new Wharfedale Pro DP-4035i Amplifier has the hardware features for installation.
The new DP-4035i brings all the DNA of the DP series into a configuration which is perfect for fixed install. A versatile amplifier solution delivering 4 channels of power to either high or low impedance systems.
The hardware is designed with installation in mind. A tamper-proof front grille protects the channel volume controls while rear panel connections, including GPIO, use Euroblocks for easy install. The power switch is also safely placed on the rear panel.
As with the other models in the DP series, the input sensitivity is selectable between 1V and 0.775 V to cater for almost any input source. It is also able to deliver up to 4 x 765 W into 2 Ohms or 4 x 765 W to a 100 V Hi-Z system.
DP-4035i also has a wide range AC input, allowing it to be used, reliably in environments where the AC supply may fluctuate.

GPIO
All the connectors needed for quick and easy installation are included with the DP-4035i.
REMOVABLE GRILLE
POWER FACTOR CORRECTION
Lets make this simple…. and call it PFC instead!
PFC, combined with the Switching mode power supplies inside DP series amps, increases the amplifier efficiency and regulates to ensure smooth power delivery even with huge fluctuations in the AC supply.
In the real world, it makes a big difference to amplifier performance and stability.
MODE SWITCHING
Rear panel DIP switches give access to the DP-4035i system configuration.
Switch the sensitivity between 0.775 V and 1.0 V or select the Lo-Z / Hi-Z operation mode.
70 V / 100 V READY
Required Amplifier settings –
Set DP-4035i mode switch to “High Z 100 V”
HPF is set at 40 Hz by the amplifier automatically to avoid low frequency transformer saturation.
Limiters are set automatically for 70 V or 100 V power output.
DSP limiters should also be set to the total power and impedance of the speakers connected.
