Wharfedale Pro XR2500 Power Amplifier

XR series are built around a massive heavy-duty toroidal transformer.

This delivers smooth and consistent power into the amplifier electronic circuits, resulting in stable and reliable output power, even in environments where AC may fluctuate.

Around the back of the XR are the balanced inputs and outputs along with configuration switches.

A handy feature are the 2 x XLR link outputs which allow for easy ‘daisy chaining’ of multiple amps – removing the need for external patching or excessive cabling.

Around the back is also the input sensitivity switch selectable between 0.775v or 1.4v.

The main ‘Bridge / Stereo / Parallel’ mode switch is also on the rear. STEREO mode makes the two channels work independently. CH1 input signal goes to CH1 output and CH2 signal goes to CH2 output. BRIDGE mode makes CH1 input signal go to the BRIDGE output socket. This is controlled by using the CH1 volume control. PARALLEL mode makes CH1 input signal go to both CH1 and CH2 output sockets. The input socket of CH2 has no effect. The channel volumes can be adjusted independently.
