** Mobile devices can stream Bluetooth music to  Nuprime Omnia A200, but it can not stream to Bluetooth earphones.

The free iOS and Android app allow you to easily control your smart music system and select your source music and group destination speakers (including receiving streamers).

Listening Optimization
The linear and neutral sonic bias of the  Nuprime Omnia A200 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.

Technical Highlights
NuPrime Omnia A200 accomplishes its seemingly incompatible objectives of being the most powerful, compact, and yet low noise streaming amplifier through the following innovative design features:

NuPrime Dynamic Low Noise Switching Power Supply (DLN PS) Design:
The power supply has a built-in dual-core dual-system that reacts to the output power demand of the power amplifier. Three levels of control utilizing a small transformer during low power, followed by a large transformer when power demand increases, and finally two power supplies working together to maximize power delivery.
The switching frequencies of the power supply are automatically adjusted between 60kHz and 180kHz, according to the output power demand of the power amplifier.
The A200 Class-D amplifier achieved low noise through a secondary feedback signal that resulted in clear and detailed sound characteristics.
The A200 speaker output incorporates a two-stage output filter to reduce high-frequency frizz for more transparent sound with less listening fatigue.
In addition, the A200 utilizes ultra-high thermal conductivity silicon oil and high purity copper blocks for fast heat conduction.

The Omnia A200 uses a compact and powerful Class D amplifier. The maximum output power can reach 250W stereo output (@4ohm speaker) and uses integrated feedback design and error correction, achieving extremely low noise and distortion. Unique Dynamic Low Noise Switching Power Supply (DLN PS) provides excellent system-level audio performance.

EQ SETTING
NuPrime proprietary EQ settings allow the users to customize their listening experience according to music preferences and audio equipment matching. Loudness 1,2 & 3 settings came from the R&D effort of the AMG series. Despite its name, Loudness settings create a presence of warmth and impact for the listener instead of louder sound.
Repeatedly pressing the Loudness button will cycle through the following EQ settings:
Flat, Loudness 1, Loudness 2, Loudness 3, Rock, Jazz, Pop, Classic
