iBasso Audio / DC03

A dual DAC adapter made by iBasso Audio. It uses a 4-core silver-plated copper cable that offers excellent sound quality, looks, and ease of use. It is compatible with smartphones and tablets, and can be used indoors and outdoors using the included USB C to A adapter. The color is silver.

■Dual DAC adapter - Transparent, high-resolution sound
・Despite its small size of 40mm x 15mm (main unit side), the DC03 is equipped with dual high-performance DAC chips.
By adopting this configuration, the DC03 achieves more powerful output voltage and channel separation than ever before, enhancing the sense of immersion in music. In addition, the DAC chip used is the ""CS43131"", a ""MasterHIFI"" quality DAC chip that meets the strict standards set by the manufacturer, Cirrus Logic.

■The brilliance of truth without dullness
・Spec sheets are not an absolute standard for measuring actual sound, but they can be trusted to measure the quality of a product.
・S/N ratio: 127dB, noise floor: <0.9μV, output level: 80mW@32Ω
・THD+N: <0.00028% (-111dB), output impedance: 0.12Ω
*The above values were actually measured using an Audio Precision audio analyzer.

■Excellent audio characteristics and sound tuning
・The DC03 is an incredible DAC adapter, achieving characteristics that are comparable to Hi-Fi audio players, such as [S/N ratio: 127dB] and [THD+N: 0.00028%].

■Noiseless and pure sound
・The noise floor of the DC03 measured with an audio analyzer is less than [0.9μV], which is almost imperceptible even when actually listening to it with your ears. It maintains a clean sound stage and enhances immersion in music.

■Powerful energy in a slim body
-Compared to the DC02, the output value of the DC03 has reached [80mW], which is about three times higher. It is even easier than carrying a mini-sized music player, and you can enjoy even difficult-to-drive IEMs on your smartphone.

■Beautiful appearance and usability
The DC03 uses brushed metal as the housing material. A [4-core silver-plated copper cable] is used to relay the main unit and Type-C connector.

■64-step hardware volume adjustment is possible using the dedicated app
-A dedicated app is available that allows 64-step hardware volume adjustment. You can control the volume in 64 steps for each volume step of the device.

■How to use
-Just connect the DC03 to an Android device with Android 5.1 or higher and you can enjoy PCM up to 384kHz/32bit and DSD up to 11.2MHz.
*This product may not be usable on some devices due to the device's system or hardware.)
*This product has a high output level, so the volume may be too loud depending on the device you connect it to.
*Depending on the device, you may need to recognize this product in the system settings in order to use it.
*The unit may become hot after using the product for a long time or when playing high-rate files, but this is a product specification and is not abnormal.
