TECHNICAL#HIGHLIGHTS#
A combination of high-power Class-D amplifier, 64-bit quad-core Arm Cortex-A53 processor,
NuPrime proprietary SRC chip, Cirrus Logic CS43131 DAC, plus other audiophile-grade
components enable the Omnia A300 to achieve world class performance above its peers.

The Omnia A300 utilizes a compact yet powerful Class-D amplifier capable of signal bandwidth up
to 100kHz with advanced integrated feedback design and error correction for very low noise and
distortion. The Cirrus Logic CS43131 combines a next-generation, low power audio DAC with a
high-fidelity headphone amplifier to provide a superior system-level audio performance. The
onboard low noise, ground-centered headphone amplifier provides proprietary AC impedance
detection to support headphone fingerprinting to provide a consistent and transparent audio
experience for the end user regardless of transducer impedances or frequency responses.

LISTENING#OPTIMIZATION#
• A user-selectable switch allows the matching to 4Ohms or 8Ohms load speakers. We
recommend the 8R setting for most use cases except for speakers with very low
impedance (i.e., lower than 4Ohms) for a more natural sound. Therefore, even if you have
a 4 ohms nominal impedance speaker, you should try to listen with 8R settings or compare
and settle down on one you prefer.
• The linear and neutral sonic bias of the A300 makes it suitable for a wide range of speakers
and sources. The EQ presets and loudness (bass enhancement) selections tuned via a high-
speed DSP allows further sound tailoring to the system and music.
