From the time Gilbert Briggs built his first loudspeaker in 1932, to the present day, Wharfedale has 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 DP-F power amplifier.

ABOUT THE DP-F SERIES

DP-F series have been engineered for mid sized venues, rental and touring applications. Enormous output power and stability at 2 ohms are features that already make DP amps special- but DP-F models also feature hugely upgraded DSP functionality. The DSP now has FIR filtering with 512 taps. This refined and powerful FIR filtering brings linear phase response to the system, resulting in a more controllable and faithful output. Input connectivity is now handled by the front panel dual RJ45 connectors allowing the DP-F to be used in an ETHERNET ecosystem with remote DSP control. DP-F series also feature a wide range AC power input and are happy with huge voltage fluctuations between 90 V and 260 V. In addition, DP-F series can drive 70 V or 100 V line systems! Think dif-FlR-ently about amps!

FEATURES

• Huge Class D power in a 1 U rack
• 2 or 4 discrete amplification channels
