Wharfedale PRO DP-4120, 4-channel PA-Amplifier​


[4x1200 W (8 Ohms) / 4x2040 W (4 Ohms) / 2 x 2400 W (16 Ohm Bridged) / 2  x 4080 W (8 Ohm Bridged)]



The high-quality 4-channel DP-4120 power amplifier is suitable for professional live sound reinforcement or fixed installations. It offers extreme performance with a low weight.
The advanced switch mode power supply and highly efficient Class-D topology offer high performance with low distortion. With 4 discrete channels and multiple operating modes, it is easy to configure the most complex installations or touring devices.

Key Features

Top model of the DP series
Super light weight - only 12.3 kg
4-channel configuration
Output power at 8 ohms 4 x 1200W
Output power at 8 ohms 2 x 4080W (Bridged)
Output power at 4 ohms 4 x 2040W
Ultra-quiet fans with variable speed
Extended protection circuit
Class D topology


Internally, a full suite of protection circuits includes thermal, overcurrent, DC, short circuit protection and on / off mute. This level of protection ensures long-term system reliability and security should the worst happen.

The LEDs on the front also keep the sound engineer up to date with error, tip, and signal LEDs.

The variable-speed fans ensure that the amplifier rack stays quiet when not in use - and cools down when the volume is high.


The DP series has stereo, bridge and mono modes. Use bridge mode with a single high-performance subwoofer or use a single DP to run your entire sound system equally.

Mono mode saves external wiring by splitting a single input to feed both channels of the amplifier.

In addition, the gains can be easily controlled using the gain switch on the rear panel. This enables installation in almost any system or location.

The DP-4120 has XLR inputs with a maximum input level of + 22 dBu, which enables integration into any typical professional audio system.


The 1U design enables high-performance systems to be configured in a confined space. In the tour rack or in the amplifier room, DP delivers reliable power from a small box.

Lightweight, powerful and portable. As simple as that!
