All-Enveloping Object-Based Sound Defines New 7.2-Channel Receiver from Pioneer, Leveraging Direct Energy HD Amplification for Thrilling Power


In addition to native Dolby Atmos and DTS:X object-based audio, Dolby Surround and DTS Neural:X™ allows standard multi-channel audio on DVD, Blu-ray Disc™, and video streaming services via media players to be upmixed for playback through a speaker configulation including height channels. The SC-LX502 features acclaimed Direct Energy HD Amplification to smoothly deliver high power through all channels simultaneously. The result is thrilling surround-sound performance, with resolution, speed, and fluency to bring out the best in object-based soundtracks. Responsive amplification is enhanced with exclusive MCACC and Phase Control technology, which resolves bass lag for improved organization.

The user experience reaches a new level of convenience with network audio playback integrating closely with mobile devices. The receiver includes FireConnect™*1 powered by Blackfire for multi-room digital and analog audio distribution; Chromecast built-in supporting streaming of an almost unlimited variety of music from various online services; and DTS Play-Fi®*2 technology to enable multi-room audio streaming to any number of DTS Play-Fi enabled speakers of any brand. Spotify®, Deezer, TuneIn, and TIDAL*3 are built in. AirPlay and Bluetooth® wireless technologies*4 are included, while 5 GHz/2.4 GHz Wi-Fi® supports streaming from networked media server and PC.

Next-generation TV displays are fed 4K/60p video supporting Dolby Vision™, HDR10, HLG (Hybrid Log-Gamma), and BT.2020 via HDCP 2.2-compliant HDMI® terminals. High-end AKM AK4458 DAC decodes Hi-Res Audio over LAN and USB for clear and expressive musicality.

Direct Energy HD Amplification
Direct Energy HD Amplification is based on Pioneer’s Multi-channel Stereophonic Philosophy, and is capable of simultaneous high-current power. Direct Power FET connects to the circuit board without wiring, preventing energy loss for quick response and high efficiency. Custom bypass capacitors enhance the best aspects of the Class D design and aid with powerful bass and overall expressiveness.

Dolby Atmos and DTS:X Audio Decoding
Dolby Atmos and DTS:X soundtracks mix sound elements independently as objects and utilize height elements that play through any speaker in a surround-sound system incorporating elevation channels. Sound moves above and around the audience with convincing realism. The SC-LX502 plays native 5.2.2-channel Dolby Atmos and DTS:X formats. DTS Neural:X pulls spatial cues from standard multi-channel soundtracks and upmixes for 3D playback through speaker systems with height channels. Dolby Surround™ also upmixes legacy sound formats so you can experience multi-dimensional playback of legacy formats in a Dolby Atmos environment.

MCACC with Phase Control Technology
MCACC (Multi-Channel Acoustic Calibration System), developed with the expertise of professional recording studios, creates an ideal listening environment in a dedicated room. Using a setup microphone, the system automatically compensates for differences in speaker size, level, and distance, and equalizes response. Phase Control Technology, meanwhile, eliminates phase-lag between main channels and subwoofer caused by the low-pass filter for improved cohesion.

Reflex Optimizer
When using Dolby Atmos-enabled speakers, high-directivity sound reflects off the ceiling, while low-directivity sound reaches the ears directly. This causes a phase shift, making sound feel uncomfortable. Reflex Optimizer resolves this phase lag and optimizes the performance of Dolby Atmos-enabled speakers for clear sound imaging. Improved integration creates a clear and comfortable sound field.

4K/60p Video with HDR10, HLG, Dolby Vision, and BT.2020
All HDMI terminals support 4K/60p video, 4:4:4 24-bit video pass-through, and the HDCP 2.2 digital copy-protection standard for playback of premium content. Video with HDR (High Dynamic Range) in HDR10 or HLG (Hybrid Log-Gamma) formats is passed through to a compatible display, together with Dolby Vision and the wide-color-gamut of BT.2020 for vividly rich reproduction.

Premium 768 kHz/32-bit DAC for Hi-Res Audio
The SC-LX502 features a high-grade AKM AK4458 768 kHz/32-bit Multi-channel DAC. The device offers clear and precise audio conversion with a unique output filter assuring low distortion and excellent S/N performance. Direct DSD 11.2 MHz/5.6 MHz/2.8 MHz and DSD 5.6 MHz/2.8 MHz with PCM conversion are supported, as are FLAC, WAV, AIFF, and Apple Lossless to a maximum 192 kHz/24-bit resolution*6.

FireConnect™ Wireless Multi-room Audio
FireConnect™ mirrors network audio and sources connected to the AV receiver’s analog inputs on wireless speakers. Music selection, speaker grouping, and control are built into Pioneer Remote*5 app for iPad, iPhone, iPod touch, and Android™ phones/tablets.

Chromecast built-in Music Streaming Platform
Stream any music from your smartphone, laptop, or PC to the SC-LX502 and control playback with Chromecast™-enabled apps on iPad, iPhone, iPod touch, Android phones/tablets, Mac or Windows® PC, or Chromebook™. When used in conjunction with Google Assistant built-in speakers such as Google Home™, users can say “Ok Google” to request music, podcasts, and internet radio from services for playback on any household audio system supporting Chromecast built-in.

Ready for DTS Play-Fi
DTS Play-Fi technology provides high-quality music streaming from connected online services, networked media servers, and device library over Wi-Fi to any number of compatible products using the Pioneer Music Control App*5 available for iPad, iPhone, and Android phones/tablets. DTS Play-Fi automatically synchronizes the music in every room and supports streaming different sources to different speakers.
