Achieve 4K Ultra HD pass-through with HDR and 3D support via HDMI with the Pioneer VSX-831-K 5.2 Channel Network A/V Receiver. It produces up to 80W of power per discrete channel at 8 Ohms for room-filling sound. MCACC sound optimization will allow you to tailor the sound to your room's specific acoustics. Built-in Bluetooth connectivity allows you to listen to music wirelessly from your favorite Bluetooth-capable device and AirPlay will allow you to connect to your compatible iOS devices. You can also attach a USB drive to the USB port on the front panel to play your MP3, WMA, AAC files, and more.
The VSX-831-K is equipped with seven HDMI inputs and one HDMI output. The HDMI output supports ARC for the reproduction of TV-based audio, such as your TV's built-in Netflix or Hulu apps. It also features an icon-based, on-screen GUI for simplified control. You can also control it with the iOS- and Android-compatible iControlAV5 Remote Control app.
Note: Not all services are available in all areas. Access to certain Internet-based content may require a subscription to a service.
Pioneer designed the VSX-831 AV receiver with a 5-channel discrete amplifier with the same quality on all channels delivering up to 80 Watts of power per channel.
As a solution for phase lag between the subwoofer and main front speakers, Phase Control compensates for delayed bass to improve sound synchronization. As a result, it makes LFE seem more dynamic and achieves clear reproduction of sound in the mid and high frequency bands.
384 kHz/32-Bit DAC
With the AK4458, a 384 kHz/32-bit DAC (digital to analog converter) produced by AKM, the VSX-831 delivers enhanced audio reproduction.
MCACC Sound Optimization
Pioneer's MCACC (Multi-Channel Acoustic Calibration System) is designed to help you create the optimum acoustic environment in any room in the house. With a custom microphone, the system automatically compensates for differences in speaker size, level, and distance, and equalizes their response.
Built-In, Dual-Band Wi-Fi and Bluetooth Wireless Technology
The VSX-831 lets you enjoy music wirelessly from iPhone, BlackBerry, Android, computer, or any other compatible sources via built-in Wi-Fi and Bluetooth technology. With two antennas providing dual-band Wi-Fi (2.4 and 5 GHz), you have a greater network range and throughput.
Google Cast Ready
With Google Cast compatibility built-in (via a future firmware upgrade), you can use your mobile device to play back your favorite music, radio, or podcasts through the receiver, controlling the audio from anywhere in the house by using Cast-enabled apps available for iOS and Android devices, Mac and Windows computers, and Chromebook.
FireConnect, powered by Blackfire, allows you to play any audio source connected to the receiver-from vinyl to streaming audio-wirelessly to a FireConnect-compatible speaker placed anywhere in the home.
4K UltraHD and HDR Compatible with UHD Upscaling from 1080p
The VSX-831 supports 4K/60p/4:4:4 24-bit video signal transmission using HDCP 2.2 technology, ensuring compatibility with 4K UltraHD sources and televisions with HDR. 4K upscaling technologies have been incorporated to upscale 1080p content to near-4K resolution.
