Audio Scaler

Pioneer's latest Audio Scaler technology consists of Hi-bit32,
Up-Sampling, and Digital Filter. The Hi-bit32 Audio 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—176.4 kHz/192 kHz 32-bit by
auto, and selectable from 176.4/192, 88.2/96, 44.1/48 kHz
frequency, 32/24-bit rate by manual setting—offering realistic
reproduction of the content. The features can be controlled on the
Sound Explorer screen of the iControlAV5 app.
Hi-bit32 Audio Processing
The technology works to create undistorted sound,
bringing out the best in the 32-bit DAC. The 32-bit
DAC hardware alone does not reproduce better
sound. Maximum performance is gained
by applying the Hi-bit32 processing to expand signal
resolution, creating more detailed, smooth sound,
closer to the original analog signal. Hi-bit32 Audio
Processing also increases the sound pressure for a tactile listening
experience, and the more channels you have, the more impressive
it becomes. It is effective for multi-channel content on DVD/Blu-
ray Disc as well as CD audio, and works with any disc player.
Up-Sampling (192 kHz/32-bit)
The Up-Sampling feature of the Audio Scaler upgrades the sound
with reduced noise, providing maximum quality audio playback of
up to 192 kHz/32-bit.
Digital Filter
The world's first digital filter for AV receivers let you
enjoy two types of sound characters by switching the
DAC — "Slow" for soft and warm, and "Sharp" for
solid and tight sound.
