Fully Balanced Design
Flagship Desktop DAC: A fully balanced digital-to-analog converter preamp with multiple inputs and outputs. Fosi Audio's first DAC to support HDMI ARC input and comes equipped with a high-performance ES9039Q2M chip to deliver rich and superior sound.
Premium Chipset: The ZD3 features the chipset consisting of XMOS XU316+ES9039Q2M+QCC3031+LME49720. It supports high audio resolution, with a maximum capability of DSD512 and PCM 32bit/768kHz sampling rates, providing unparalleled clarity and depth.
Versatile & Flexible: The ZD3 offers comprehensive connectivity, supporting inputs like Bluetooth, USB, OPT, COAX, HDMI ARC, and balanced XLR/RCA outputs. This flexibility allows you to customize your audio system to suit various setups and scenarios.
Ease of Use: The ZD3 adopts a 1.5-inch OLED display, remote control, preamp bypass switch, and 12V trigger in/out interfaces, allowing synchronized power on/off with other home audio devices, all for a good user experience.
Family Design: Featuring the same design language as the ZA3 amplifier: compact and exquisite appearance and audiophile-grade components for high performance and excellent sound quality. Pair it with the ZA3 to create a robust home audio system.
When the ZD3 is used with an LG TV, a bug in the LG TV system may cause issues with the HDMI-CEC function. Specifically, after turning off the TV with the power button or remote control, both the TV and ZD3 may automatically power back on after a short time. If you are using an LG TV, we recommend disabling the HDMI-CEC function. We are working hard to resolve this issue and sincerely apologize for any inconvenience caused. Thank you for your understanding.

=== FAQ ===
Q: Does the ZD3 have HDMI CEC? Can I use my TV’s remote for volume control?
A: The ZD3 does have HDMI CEC. In HDMI ARC input mode, you can control the ZD3's volume with your TV remote, but it does not support HDMI EARC.
Q: Does the ZD3 have a built-in headphone amplifier? Does it have an analog input AUX?
A: No. The ZD3 does not have a built-in headphone amplifier and cannot connect headphones; it also does not support an analog input AUX.
Q: Does the ZD3 support ASIO and WASAPI drivers in Windows 11?
A: Yes, the ZD3 supports both ASIO and WASAPI drivers in Windows 11.
Q: Can I use the Trigger Out from the ZD3 to control two ZA3 amplifiers?
A: Yes, you can use a dual 3.5mm male splitter cable to control two ZA3 amplifiers synchronously.
Q: How many Sparkos SS3602 op-amps do I need for the ZD3?
A: For RCA output, replace one op-amp. For XLR balanced output, replace two op-amps corresponding to the left and right channels.
Q: How to replace the op-amps?
A: Tools required: needle-nose pliers, tweezers, and an H2.0 hex screwdriver.
1) Use the hex screwdriver to remove the two screws on either side of the rear panel.
2) Remove the front panel knob, and with needle-nose pliers, unscrew the nut and washer from the potentiometer, then slide out the front panel.
3) Disconnect the components near the notch of the circuit board by the front panel, which is connected to the Bypass mode switch.
4) Carefully pull out the mainboard, and you will find three interchangeable op-amp chips.
5) Replace one op-amp for RCA output and two for XLR output, corresponding to the left and right channels.
6) Use tweezers to gently pry out the op-amp chip(s) from the side pin gap.
7) Install the new op-amp chip(s) into the sockets. Ensure correct orientation by matching the '1' marking or the groove on the chip cover with the 'O1' position on the PCB. Incorrect installation may damage the op-amp.
8) After installing the new op-amp(s), connect the amplifier, power, and speakers to test if the sound is working. If all is fine, reassemble the device.
