Product Description

Unique DS400+

Powerful Chips Combo：Powerful and proven ESS ES9038Q2M and XU208 USB decoder chips, two OPA1612 op amp chips and two OPA1622 amp chips, the most luxurious chip combination brings you high-fidelity music enjoyment.Amazing Brain：XU208 is the second-generation XMOS chip, the memory is twice as high as U8, and the computing speed reaches a terrifying 1000MIPS, twice as high as 500MIPS of U8. Within a dual-crystal clock management system, effectively prevents instability due to jitter, ensures any digital audio signal input to the DAC is accurate, and further improves the sound quality.Desktop Level Decoding Capability：DS400+ headphone amplifier is equipped with powerful and proven ESS ES9038Q2M, capable of decoding up to 32bit/768kHz/32bit and DSD64-DSD512, the DS400 has a signal-to-noise ratio of up to 120dB and 129dB The dynamic range is as low as 0.0003%, and the noise is less than 2uV. Other headphone amplifiers on the market can only reach 192K/24bitIncredibly Low Noise Floor: Optimized active low-pass and BASS circuit design ensures a lower noise floor in all conditions. This headphone amp uses overvoltage protection (OVP) and dual filter circuits to ensure the stability of the power supply, while the digital and analog audio circuits each have their own power supply, which greatly reduces crosstalk.

FAQ for DS400+ headphone amplifier

Q1.About getting hot and power consumption:

1. In order to ensure the stability of sound quality, DS400 does not have a battery, so it will consume the power of the device. When connecting the DS400 to a mobile phone or other device, plan the power consumption reasonably.

2. DS400 is small in size and high in output power. It will heat up a bit during operation, but the temperature will stabilize after that. A little bit of heat means the product is working properly.

Q2: Does DS400 support in-line remote control in the headphone or phone calls answering with headphones?

1. The DS400 does not have any buttons. And it does not support in-line remote control in the headphone or phone calls answering with headphones.

2. When an incoming call comes in, the sound is still transmitted through the phone’s speaker and microphone. You can pick up the phone and make a normal call.Whether unplugging the DS400+ will not affect it.

Q3: Why can’t the product start?

1. For Windows users, the driver needs to be installed for the first use.Please download the driver, installation guide and Foobar2000&JR player on the 1Mii official website .

2. When connecting to other portable playback devices such as mobile phones, the DC5VIN port of the decoder requires additional power supply.

3. Please check whether the signal input is correctly connected, please use Type C with signal input, and need to connect “USB IN”, connect to “USB 5V IN”, it will not start normally. It is a power port.
