Since its launch in 2019, several firmware versions have significantly expanded the receiver's capabilities:
Virtual Surround Sound: Updates unlocked Dolby Atmos Height Virtualizer and DTS Virtual:X, allowing the unit to create "virtual" height and surround channels without physical overhead speakers.

Enhanced Streaming: Recent global updates from the Premium Audio Company have improved performance for services like Tidal MAX, Sonos integration, and Dirac Live measurements on newer or related models, often trickling down to the VSX-934's software ecosystem.

You can update the firmware using two primary methods, as detailed in the Pioneer Support Guide:
While the underlying hardware of the VSX-934 remains the same, the firmware polish extends to the on-screen interface and remote interaction. Users noted that the previous GUI could feel sluggish, sometimes lagging behind remote inputs.
The update optimizes the processing overhead for the OSD (On-Screen Display). Navigating the settings menu is now snappier, and switching between audio modes—say, jumping from "Stereo" to "Neural:X" upmixing—happens instantly, without the audio-drop delay that previously interrupted the immersion. Furthermore, the update fine-tunes the IR receiver sensitivity, fixing an issue where the receiver sometimes ignored commands if the remote wasn't pointed with laser precision.
