All four new models sport Ultra HD pass-through and Eco Mode.
Pioneer has announced the feature set for its new VSX line-up of A/V receivers. All four models support Ultra HD pass-through for 4K support with the VSX-1123-K capable of Ultra HD upscaling. Eco-Mode is also part of each, and allows HDMI switching and network standby to function even when the receiver is off, which is just the beginning of how Eco Mode adjusts to conserve power when possible.
After the value-centric 5.1 channel VSX-523-K, the VSX-823-K adds On Screen Display, a front HDMI port, and networking capability, including MHL 2.0, Apple AirPlay, HTC Connect, Pandora, and vTuner. The VSX-1023-K adds 7.1 support and Powered Zone 2 Audio. The Zone 2 capability allows a separate HDMI source from the main to be output to another room. Pioneer's iControlAV app allows control for both the VSX-823-K and VXS-1023-K, while the new iControlAV2013 is crucial for bringing the VSX-1123 HDZONE to bear. HDZONE, allows a third audio-only source to be routed to another room.
The VSX-523-K is listed at $279.99. The VSX-823-K is $429.99. The VSX-1023-K is $529.99, and the VSX-1123-K is $629.99.
