      Product details

      SoundImpress HY252-4CH 4x250W Ncore Quad Amplifier


      The HY252-4CH is a compact, high performance, four channel and no-nonsense class-D power amplifier. It incorporates the proven and renown Hypex Ncore® technology for nothing less than impressive performance!


      The performance stands out with authoritative and tightly controlled low registers, high dynamics and crystal clear mid- and high-frequencies. The super-low noise level generates a completely black background to reveal the tiniest of details in every recording. 


      All SoundImpress amplifiers are hand assembled in the Netherlands. The custom milled aluminum enclosure houses the Hypex NC252MP amplifier module, the best thermal material for audio devices. The in- and output connections are provided through high-quality binding posts from CMC and XLR-chassis from Neutrik and wiring from Mogami and Belden. It can operate from both 110 and 230 VAC mains voltage due to its universal mains input compatibility featuring an automatic input voltage doubler. 


      Small and powerful

      This amplifier can deliver all its power from as low as 2 ohm impedance combined with low idle loss, very low distortion and noise levels. Chief distinguishing features are flat frequency response irrespective of load impedance, nearly frequency independent distortion behaviour and very low radiated and conducted EMI. This results in performances such as the max output power of 250 Wrms at 4 ohm per channel, a Signal-to-Noise Ratio (SNR) of 121 dB and astonishing distorting level of 0.0015%.


      An amplifier is only as good as the power supply it contains. In this SoundImpress amplifier, the power supply and amplifier are located on one board. The switched-mode power supply (SMPS) providing the power for the amplifier is a compact, high power, highly efficient, regulated half bridge converter with synchronous rectification on the main output rails. These properties make this technology ideal for powering class-D audio amplifiers.
