XR 1500 

Power Amplifier (8ohms: 330watts x 2)


Overview 

The XR15 delivers  330 watts per channel into 8Ω respectively. All models feature XLR connectors, making cable management and daisy-chaining for installers or when used in flight cases. All models feature full circuitry protection for thermal, over current, DC, output short circuit along with power on / off muting.All models also feature ultra quiet variable speed fans. Rear panel mode switches allow for selection between Parallel, Stereo and Bridge modes along with input sensitivity switching. Meanwhile, a huge toroidal transformer takes care of any AC power fluctuations.Large front air vents and steel construction aid heat dissipation to ensure long life and reliable performance that comes with any Wharfedale Pro amplifier.


Features

An XR series amplifier features comprehensive protection circuitry. This ensures that no matter what problems might exist with external cabling, AC power or loudspeakers, the amplifier will protect itself, and its surroundings. Front panel LED's give immediate and clear feedback to the situation. The LED will be "Fault" light, illuminated and the amp will go into protection mode. A handy feature is the 2 x XLR link outputs which allow for easy 'daisy chaining' of multiple amps - removing the need for external patching or excessive cabling.A rear panel 'Reset' button is now available to reset the amplifier. Handy 'Clip' LED's are also visible from the front panel. Even from a distance, its simple and clear to see and understand the status of the amp. Around the back of the XR are the balanced inputs and outputs along with configuration switches.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.
