 D2 AMPLIFIERS with "ASP"

D2 amplifiers are Class-D High Efficiency Power Amplifiers with Loudspeaker Management included. D2-series features latest technology in Class-D amplifier design including extremely high fidelity sound with frequency-independent harmonic distortion performance, high efficiency design and very low total weight. Speaker preset filters are done in analog domain (ASP = Analog Signal Processing) resulting in zero latency, wide bandwidth and natural transparency.
D2 MODELS
D2.21   2 x 125W/4 ohms (250W/8 ohms bridged), 2 x ASP
D2.22   2 x 250W/4 ohms (500W/8 ohms bridged), 2 x ASP
D2.23   2 x 250W/8 ohms (no bridge mode), 2 x ASP
D2.25   2 x 500W/8 ohms (no bridge mode), 2 x ASP
D2.41   4 x 125W/4 ohms (2 x 125W/4 ohms + 1 x 250W/8 ohms bridged), 4 x ASP
D2.42 4 x 250W/4 ohms (2 x 250W/4 ohms + 1 x 500W/8 ohms bridged), 4 x ASP
(first number represents the number of channels and the second first number of the nominal rms power per channel)

All D2 amplifiers are fitted with user variable speaker specific presets for specific loudspeaker including high-pass and low-pass filters, parametric EQ and very transparent optical limiter circuit. Filters can also be bypassed if additional DSP is used such as aux outputs of D80DSP.
All models are powered by auto mains voltage sensing switch-mode power supply with over current and over voltage protection system and optimized low noise cooling system.
