Project Details

D2 AMPS is a class D high-efficiency power amplifier with speaker management function. The D series represents the latest technology in amplifier design, with extremely high fidelity sound, frequency-independent harmonic distortion performance, efficient Class D design and extremely low total weight.

D2Q

D2Q is a 4-channel (4 × 125 W/4 ohm ) amplifier, which can be used as an independent system amplifier or D80DSP expansion amplifier , driving from I 3, I 5 or C12 top to small subwoofers, delay lines and even F series studio monitors Any device.   

D2 I

D2 I is a dedicated I series amplifier with 2 in 4 out fixed dual amplifier routing for top + sub configuration; I 3 and I 5 filter and limit presets for Aura Audio XD8, XD10 and XD12 subwoofers and free The subwoofer is filtered.  

D2 X

D2 X is an expansion amplifier with 2 inputs and 2 outputs, fed by the D80DSP auxiliary DSP output or as an independent system amplifier to drive any device from the top of I 3, I 5 or C12 to a small subwoofer or delay line.

All D2 amplifiers are equipped with fixed system controllers for specific speakers, including high-pass and low-pass filters, parametric equalizers and state-of-the-art optical limiter circuits. If an additional DSP is used, such as the auxiliary output of the D80DSP, the filter can also be bypassed. All models are powered by an automatic mains voltage sensing switch mode power supply with overcurrent and overvoltage protection systems and an optimized low-noise cooling system.
