ever SOLO High Resolution DAC and Headphone Amplifier

Introduction

Thank you for choosing Eversole DAC-Z6.
DAC-Z6 is a compact and exquisite fully-balanced DAC and headphone amplifier. The decoding solution is XMOS 316 and dual ES9068 DAC chips, which support up to DSD512, PCM 768Khz@32Bit, and MQA decoding. Good decoding quality is guaranteed due to the low noise and distortion for D/A conversion.
Two independent channels correspond to two ES9068 DAC chips respectively for D/A conversion, so that channel interference are effectively avoided. High- precision resistors and fully balanced circuits are designed for lossless amplification for XLR, RCA, and headphone output. Channel separation, dynamic range, and sound integrity are greatly improved.
Multiple inputs on DAC-Z6 are available for hi-res digital audio decoding. USB DAC input can be connected to a 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. DAC-Z6 can also connect mobile devices by Bluetooth, just like a Bluetooth decoder, it is BT5.0 and supports APTX HD, LDAC, etc.
The professional headphone driving circuit in DAC-Z6 supports good indicators and strong drive. As a high-performance headphone amplifier, high and low gain modes are optional, and headphones between 16-300 ohm impedance can be easily driven.
Eversole DAC-Z8 is the perfect partner for high-fidelity audio equipment or high-end headphones. The exceptional preamp performance, good sound quality, and strong headphone driving force will bring you with authentic HiFi music experience.
Please read this manual before using the device so that you could use it correctly.

Output

1. Headphone output Connect a headphone with a 6.35mm single-ended jack to a DAC-Z6 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-Z6 RCA output to a power amplifier or active speaker RCA input by an RCA audio cable.

3. XLR balanced output Connect DAC-Z6 XLR output to power amplifier or active speaker XLR input by XLR audio cable.
   In order to reduce the possible signal interference of the RCA and XLR simultaneous output, XLR and RCA can be output separately by setting in the menu. Higher audio indicators and better sound quality can be obtained through separate output.
