HPS 2500 is a 2 channel power amplifier that delivers up to 2 x 1400 W RMS @ 2 Ω (2800 W RMS bridged @ 4 Ω).
XLR inputs for patching in signals as well as Speakon ports for connecting speaker systems are provided for the maximum flexibility.
A forced air cooling system maintains a low operating temperature.

Standard Signal Inputs Module: The S Series amps are equipped as standard with twin Neutrik® XLR, doubled by two other XLR connectors for linking purposes. In the 4 Channel models an XLR input per channel is provided with the signal linking facility.
Analog Processor Module: permits a very easy, user-friendly signal processing to enable the amp to set up a bi-amp system without any other outboard device. These are the Processor's main characteristics:
• 2-way stereo crossover (dual mono or single bridged sub output)
• 24dB/oct Linkwitz-Riley configurable crossover (90, 100 o 120Hz)
• Adjustable attenuation in the High-pass outputs (-3, -6 or -9dB)
• Adjustable Limiter, relative to Max. Output (-3, -6 or -9dB)
DSP44_S Module: Digital Signal Processor fully programmable through an USB port. These are the Processor's main characteristics:
• 4 Inputs/4 Outputs or 2 In/2 Out free route configurable.
• 24 bits/192 kHz 256x Oversampling Converters.
• Output Delay: 0 to 7.1 meters (20.69ms) per channel.
• XOver: Up to 48dB/oct Butterworth, Linkwitz-Riley and Bessel.
• EQ: 9 filters per channel (Parametric, Shelving, LP,HP,BP,SB).
• Gain, Mute and Phase inversion per channel.
• RMS Power and Peak Voltage output limiter per channel.
• Real Time operation from USB or front panel configuration.
