Introduction

Thank you for choosing EVERSOLO DAC-Z8.
DAC-Z8 is an all-in-one DAC, fully balanced preamp and headphone amplifier.
With the integration of XMOS 316 and ESS flagship ES9038 Pro DAC chip, DAC-Z8 is capable of decoding up to DSD512, PCM 768Khz@32Bit and MQA and ensuring D/ A conversion with low noise and distortion.
DAC-Z8 analog circuit has imported the multi-channel shunt compensation technology. 8 OPA1612 correspond to 8-channel output for I/V signal conversion, then output to 2 channels in parallel. In addition to high- precision resistances and fully balanced circuit design, it helps amplifying XLR, RCA and headphone output signal lossless, improving channel separation, dynamic range and the sound integrity.
There are diverse inputs for hi-res digital audio decoding for DAC-Z8. USB DAC input can be connected with computer and streamer; Type-C is to connect mobile devices like mobile phones or tablets; Optical and coaxial are to connect streamers and CD players.

Output

1. Headphone output
   Connect a headphone with 6.35mm single-ended jack to DAC-Z8 headphone jack.
   Note: Select the suitable gain mode in DAC setting to adapt to headphones with different sensitivities and impedances.
   Headphone input has a higher priority than XLR/RCA, when it is in the mode of headphone output, the signal output of XLR/RCA will be disconnected.

2. RCA output
   Connect DAC-Z8 RCA output to power amplifier or active speaker RCA input by a RCA audio cable.

3. XLR balanced output
