Pioneer - Class D "Direct Energy HD Amp" AV amplifier - 2 new models (SC-LX57, SC-2023)

Pioneer is going to release 2 new AV amplifier models (SC-LX57, SC-2023) in late July.

They feature “Direct Energy HD Amp” that is capable of supplying high-revving power simultaneously while playing multiple channels so that they can play powerful sounds. They can play high-resolution sounds like WAV, FLAC, Apple loss-less, and AIFF and also play DSD file with a very high sound quality.

In particular, because of its new “Audio Scaler” functionality, “SC-LX57″ can upgrade all 2ch digital contents including CD and 96.kHz high-resolution sounds onto 192kHz/32bit and 176.4kHz/32bit. In addition to that, it has “SABRE 32bit Ultra DAC” manufactured by ESS Technology, Inc, which enables “SC-LX57″ to play rich bass sounds.

Both models are compatible with iPad/iPhone/iPod touch/iPod nano, MHL, HDMI terminal, AirPlay and wireless connection.

NXP's new audio chip pumps up the volume for mobile devices speakers

Dutch company NXP — best known for it’s NFC solutions — introduced a new audio chip today that’s set to significantly improve the sound quality of the micro-speakers commonly built into mobile devices such as smartphones and tablets. The TFA9887 integrated circuit combines NXP’s CoolFlux audio DSP, a class-D amplifier with current sensing and a DC-to-DC converter to boost the output level of micro-speakers up to five times (up to 2.6W RMS) without damaging the driver. Class-D amplifiers are highly efficient and, when combined with a DC-to-DC converter, provide a strong and clear signal regardless of battery level. With current sensing, the chip uses feedback from the driver to optimize power delivery, allowing micro speakers to provide louder, richer sound with deeper, tighter bass over the entire lifetime of a mobile device. Are you ready to turn it up to 11? Check out the full PR after the break.

Update: Hit the break for NXP’s PR video.
