QS-TWO-ISO

2-Channel Class D Plug+Play Nano Digital Amplifier

With an impressive 2 x 95 watts RMS, the small QUANTUM QS-TWO is anything but puny. On the contrary, it effortlessly drives speaker systems with 4, 3 or 2 Ω impedance and remains very stable even under critical loads. With a mono bridge output of 190 watts RMS at 4 Ω, it can also coax decent bass out of subwoofers. It also impresses with its high-end sound: thanks to the enormous bandwidth of up to 60,000 Hz and a sensationally low distortion factor of <0.007% (THD+N @ 5W), the QS-TWO is right at the top. Perfect for HD AUDIO.

 

ESX is so good at building Class D amplifiers that the QS-TWO has a sensational efficiency of up to 90% and is free from EMC interference. The modern technology saves power, relieves the vehicle's electrical system and protects the high-quality components from overheating. Thanks to the high efficiency, there is no need to pull any annoyingly thick power cables. If you want to keep it really simple, you can use the QS-TWO-ISO, which can be connected via a ready-made ISO cable harness, for example behind the car radio. On the signal side, the QS-TWO is controlled via cinch or alternatively via the integrated high-level inputs (with EPS).
