MTX Audio TX Series 220W 1/2-Channel Amplifier - TX2275

MTX Audio TX Series 220W 1/2-Channel Amplifier - TX2275


The MTX TX2275 amplifier is powerful and very flexible. It can confidently power 2 speakers (2Ω~8Ω) at the front. It can also be used to power a 4Ω subwoofer with 225W RMS of clean power, perfect for the MTX FPR slimlines, TN12, RT12 and 3512. In any case, it shines with its legendary dynamics and exceptional musicality. The variable active filter allows it to be extremely precise: 12dB/oct high pass or variable low pass from 50 to 120Hz. If you don't know where to start adjusting the active filter, the potentiometer is equipped with an 80Hz "click" position. To avoid interference problems, we have equipped the TX2275 with balanced inputs. They perfectly isolate the audio ground of the amp so that it does not mix with the noisy ground of the power supply. This is a powerful technique that is usually found on high end amps. If your car stereo does not have RCA outputs, you can connect the TX2275 to the high level inputs. All you need to do is connect the factory speaker output cables directly to the high level input of the amplifier. Simple yet very practical.
