Digital amplifier
DQX-14400 is a digital power amplifier with a maximum output power of 4 x 1200W @ 8 ohms / 4 x 2100W @ 4 ohms / 4 x 3600W @ 2 ohms and a maximum bridged output power of 7200W (RMS) @ 4 ohms. The unit has a very efficient power/weight relation and measures only 1 rack unit. The amplifier comes with an advanced SMPS circuit and APFC design to provide a variable power supply with extremely high efficiency. DQX-14400 further provides circuit protection for short-circuit, over-voltage or under-voltage, temperature control, DC protection, peak clipping, amplitude limiting and VHF protection, as well as an automatic temperature control fan system. Very few amplifiers in the market offer that high power efficiency with such low distortion as the DQX-14400.
