FPGA-Master3.0 + Dual Accusilicon fs Oscillators | The Upgraded Audio System Controller
The DX340s FPGA-Master3.0 brings together iBasso's algorithm achievements from the past few years and is the reason we have been able to accomplish breakthroughs for our discrete DAC. As the audio system controller, it directly requests audio data from the SoC and plays a major role in signal reproduction and maintaining signal integrity. It synchronizes and generates all audio clocks utilizing two Accusilicon femtosecond oscillators to achieve a fully synchronized single clock source.

Advanced Harmonic Adjustment
The number of LUT units in this new FPGA chip is 7.5 times that of FPGA-Master2.0. This allows the FPGA-Master3.0 to be equipped with our new and exclusive harmonic adjustment algorithm, which makes odd and even harmonics adjustment possible.

FPGA-Master3.0 is The Core | Driving 128 PWM-DACs to Work at Their Maximum Performance
The DX340’s FPGA-Master3.0 brings together iBasso's algorithm achievements from the past few years and is the reason we have been able to accomplish breakthroughs for our discrete DAC. As the core of the discrete DAC, the FPGA-Master3.0 generates the PWM signal, which then arrives to the discrete 16 Sets of cascaded 8E PWM-DACs for decoding.

128 Discrete PWM-DACs | Leading in Both Quantity & Precision | The Pinnacle of Portable Player
The DX340 employs 16 Sets of cascaded 8E PWM-DACs. There are 4 sets per L+, L-, R+, R-, which is 32 PWM-DACs. The quantity of the DAC exceeds that of other portable discrete DACs by more than 6.4 times. The remarkable integration of accurate decoding and a substantial quantity of extremely high-quality DACs results in a THD+N level of -119dB, significantly outperforming similar open source PWM-DACs (-80dB), clearly positioning the DX340 as a leader in this industry.

Patented Dual Battery Power Supply Structure | Digital & AMP Sections Are Separately Powered
The power supply is a fundamental component that significantly influences the sound quality of the player. When the player operates on a single battery, high load conditions can lead to an inadequate power supply, resulting in additional distortion and a subsequent decline in sound quality.

DX340 features iBasso's innovative dual battery structure, ensuring that both the digital and AMP sections are powered by an independent battery for optimal performance. An independent battery power supply guarantees the stability of the AMP section's power, while effectively isolating electromagnetic interference from the digital section. This significantly mitigates the decline in sound quality that can result from inadequate power supply. Simultaneously, we have enhanced the dual battery structure of the DX340, implementing a single battery indicator for charging and power monitoring. When linked to a USB charger that provides adequate power, the DX340 will override the internal battery system and operate solely on the external power source. The ever-evolving dual battery structure stands as a testament to our unmatched innovation.

Replaceable AMP Card Design | AMP15 With BUF643A x8 Comes as The Standard | Supports 12V DC-IN
DX340 utilizes our replaceable amp card design, which is compatible with the AMP12, AMP13, & AMP14, and will also be compatible with other upcoming AMP1x series AMP cards.

The standard AMP card AMP15 utilizes 8 pieces BUF634 to ensure the high output ability. This new AMP card also supports external DC 12V power supply. After connecting to the DC 12V power supply, the amp power supply will be increased from the default ±8V to ±12V, and the "Super gain mode" will be available, the output power will be up to 2150mW+2150mW@32Ω. The exceptional output power allows the DX340 to drive IEMs and headphones with ease.

Qualcomm Snapdragon 665 SoC | 8G RAM + 256G ROM
The DX340 features a Qualcomm Snapdragon 665 SoC, complemented by 8GB of RAM and 256GB of UFS 2.1 high-speed memory, guaranteeing seamless system performance. The extensive memory capacity facilitates with ease the installation of substantial software volumes without concern. The DX340 offers Micro SD card expansion capabilities of up to 2TB, ensuring that storage space is never a concern.

6.0-inch 1080P AMOLED | Rich colors & High Contrast | Visually Appealing & More Energy Saving
DX340 features a 6.0-inch 1080*2160 AMOLED display. The individual light emission of AMOLED screen pixels results in an impressive contrast ratio in the millions. AMOLED technology offers superior energy efficiency compared to LED screens, delivering vibrant and rich colors that are visually appealing.

316 Stainless Steel Chassis | User Removeable Back Cover Design
The DX340 shell is made of 316 stainless steel. Compared with aluminum alloy, stainless steel is more stable and has better acoustic performance. The DX340 adopts a CNC machined finish with a surface that is polished and brushed. The unique metallic luster of stainless steel makes the product present a luxurious texture with a high-end feeling that aluminum alloy shell does not possess.

Top-tier USB Receiver | Allows The DX340 to Work as A USB-DAC
DX340 is equipped with a professional USB receiver. The USB DAC mode supports PCM 32bit/768K and Native DSD512. The ultra-low latency also allows you to enjoy the ultimate experience when watching movies or playing games.
