Pioneer LX57 AV receiver

9.2-Channel THX® Ultra2 Plus, AIR Studios AV Receiver Featuring Class D (Direct Energy HD) Amplifier with Ultra HD (4K) Upscaling / Pass Through.

Pioneer SC-LX57

Massive Power Meets Great Design

Driven by powerful Class D amplification, the SC-XL57 produces a continuous 190 W output per channel, allowing you to enjoy your music with maximum impact. The SC-LX57 integrates an ESS Technology Inc. SABRE 32bit Ultra DAC, the industry’s benchmark for audio digital-to-analogue conversion, to reproduce music with unsurpassed fidelity. With an Audio Scaler on board even regular CD quality content can be upscaled up to 192 kHz/32 bit to create a “high-resolution” experience. The receiver plays back DSD files, high-resolution AIFF, Apple Lossless, WAV and FLAC files for which gapless playback is supported as well.

Enjoy playback in other rooms via HDZone, a Zone 2 HDMI out for routing either the same signal as the main zone or a separate source to a second zone via HDMI. On top of that you get a digital connection to connect the receiver with your iPod, iPhone, iPad or Android device (via MHL), and you can enjoy easy-to-operate worldwide internet radio (vTuner) and network streaming via DLNA or Apple AirPlay when you connect via LAN.

A built-in ECO Mode lets you save energy without compromising on sound and video performance. Compatible (free) smartphone/tablet apps include the advanced remote control app iControlAV2013.

Audio Scaler
Pioneer’s latest Audio Scaler technology consists of Hi-bit32, Up-Sampling, and Digital Filter. The Hi-bit32 Audio Signal Processing improves resolution and density, while the Up-Sampling reduces noise. Then the Digital Filter creates soft, natural sound and improves transient response and pre-echo effect. The three features integrate to upscale all 2-channel audio content up to 176.4 kHz/192 kHz 32-bit playback, offering realistic reproduction of the content.

Direct Energy HD Amplifier
The Direct Energy HD Amplifier has further evolved as Class D Amplifier, equipped with the Direct Power FET featuring a simple structure with superior heat dissipation. This year, the digital circuit power supply has been redesigned to provide a clean electric current with reduced noise. The top two models have separated operational amp section and amplifying section with dedicated ICs for minimum interference, while the other AV receivers adopt a directly-coupled IC with precise signal transmission.
