Product Usage Precautions
To prevent the risk of fire, electric shock, or product damage, do not expose this device to rain,
moisture, dripping, or splashing. Do not place water-filled objects, such as vases, on top of the device.
To ensure proper ventilation, do not install this device in a bookcase, built-in cabinet, or other enclosed
spaces. Ensure that curtains or any other objects do not block the ventilation holes to avoid the risk of
electric shock or fire caused by overheating.
Do not place open flame sources, such as lighted candles, on the device.
Do not open the chassis to avoid electric shock. The casing should only be opened by qualified
professional technicians.
Placement
Please place the player on a flat surface, away from direct sunlight, and avoid high temperatures,
high humidity, and frequent vibrations. Otherwise, it may damage the chassis and other internal
components, thereby shortening the lifespan of the device.
To prevent distortion and abnormal acoustic effects, do not place heavy objects on the device.
When positioning the device, maintain a distance of at least 15 cm from the wall.
Power Supply
Do not use excessive voltage, as this may overload the device and cause a fire. Connect the AC
power cord correctly and ensure it is not damaged. Do not pull, bend, or place heavy objects on
the power cord.
Do not overload wall outlets. Be extremely careful when using extension cords or power strips,
as they can cause electric shocks or fire hazards.
Do not trap the AC power cord between the player and walls or bookshelves.
To prevent damage caused by lightning, unplug the power cord from the outlet when the device
is not in use for an extended period.
Please use the dedicated power adapter supplied with this device correctly. Do not use adapters
that exceed the rated voltage of the device.
Moisture Proofing
When using this device, avoid damp environments such as humid basements. Moisture
condensation can damage the internal components.
��
Service
Do not attempt to repair this device by yourself. Unauthorized repair, disassembly, or reassembly by
non-professionals may lead to electric shock or product damage. If any of the following conditions
or other unlisted malfunctions occur, please unplug the power cord and contact your local dealer or
service center. (National Service Hotline: 0755-83014160)
A. Abnormal sound or picture
B. Damaged power cord or plug
C. Liquid spilled or foreign objects entered into the device
D. The device has been exposed to rain or water

Basic Functions
Main Interface Overview
��
Input Mode
Audio Format
The interface layout features defined zones, displaying four core sets of information clearly: Input Mode, Audio
Format, Sampling Rate, and Volume. Users can instantly check the current audio status upon booting up without
digging through menus. Key parameters like sampling rate and format are clear at a glance, significantly increasing
operational efficiency for audiophiles.
Input Mode: Displays the current audio input source (e.g., USB, Bluetooth, or Coaxial).
Audio Format: Displays the encoding format of the current audio track (e.g., PCM, DSD, etc.).
Sampling Rate: Displays the sampling rate of the current audio signal (in kHz), indicating the audio resolution accuracy.
Volume Display: Visually demonstrates the current output volume via a progress bar combined with a numeric value
(in dB).

Rotate the volume knob on the right side of the DA70 body to enter volume adjustment mode. The screen will
display the current volume value and progress bar. Rotate clockwise to increase the volume, and counter-clockwise
to decrease it. Once adjusted, release the knob and the device will automatically return to the main interface after 2
seconds.
From the main interface, short press the volume knob on the right side of the body to enter the settings menu.
After entering the menu, if no further action is performed, release the knob and the device will automatically return
to the main interface after 2 seconds.

1.Bluetooth Input Mode
Operating Steps:
1.In the machine's settings interface, navigate to the input mode, and short press
the knob to select "Input Mode: BT".
2.urn on Bluetooth on your phone, scan for devices, find "ZIIZOO-BT-xxxx ", and
pair/connect.
3.For certain mobile phones, if there is no audio during music playback, you may
need to adjust the sound output settings inside the music playback software.
Note:
*The illustration is an example showing some connected devices; more devices can actually be connected.
*Ensure the rear Bluetooth antenna is screwed tightly and positioned upright. Do not place the device inside a cabinet.
*It is recommended to play locally downloaded songs on your phone. Streaming audio online is susceptible to network
fluctuations and often yields lower sound quality.
*Keep the device separated from your Wi-Fi router, or configure your Wi-Fi to the 5GHz band. 2.4GHz Wi-Fi and
Bluetooth share similar frequency bands and can easily interfere with each other.
*(Note: Once the phone is successfully connected via Bluetooth and music is playing, the display screen will indicate
the actual sampling rate value).

2.Coaxial Input Mode
Operating Steps:
1.Cable Connection: Please use a high-quality 75Ω shielded audio coaxial cable with RCA connectors.
2.In the machine's settings interface, navigate to the input mode and short press the knob to select "Input
Mode: COAX".
3.The source audio device must have its sound output mode configured to Coaxial / SPDIF output.
4.Select Stereo / PCM as the output format.
Note:
*The illustration shows examples of some connected devices; more devices can actually be connected.
*The cable used must be a digital coaxial cable with a constant impedance of 75 Ohms.
*Select COA for Coaxial input.
*Once the decoder receives a valid audio signal, the display screen will indicate the sampling rate (e.g., 44K).
��
3.USB Input Mode
When USB input is selected, you can output audio via XLR or RCA. Below are the connection and operational methods:
1.(Note: Per the rear panel diagram on Page 7, the port is actually a USB-C input interface. Translating standard
instruction text as written): Use a high-quality shielded decoding cable, plug the USB connector into the DA70's USB
input interface, and connect the other end (USB-A/C) to a computer, mobile phone, or other source devices.
2.Use a pair of XLR balanced audio cables or high-quality RCA interconnects to connect the Left and Right channels of
this unit's output interfaces to the corresponding XLR or RCA input interfaces on your amplifier or powered speakers.
3.In this unit's input/output settings, select USB as the input source and XLR/RCA as the output destination. Set your
amplifier's input source to XLR or RCA; no additional configuration is needed for active/powered speakers.
4.For Windows computers, after properly installing the driver and audio player software according to the tutorial, you
can play high-resolution audio files up to DSD512 and PCM 768kHz 32-bit.
5.When connected to a mobile phone's Type-C port, the phone can output audio directly to the DA70 for hardware
decoding and playback.
��
Note:
*Windows computers require downloading and installing a dedicated driver (Scan the QR code on the right for video
tutorials and driver downloads).
*Mac computers will automatically install the driver. Simply select the USB output device in the system's sound output
settings.
*Some Android devices (such as Huawei phones) require configuring the USB output mode to "MIDI" before
connecting the cable. If there is no sound, reconnect the cable and turn up the volume.
*For models like OPPO/VIVO, you need to go to settings, locate "Additional Settings", and enable the "OTG" switch
before making the connection.
*To play DSD audio from a phone, use a compatible app and enable its "USB Exclusive Access" function. (This feature
depends entirely on app compatibility; any playback anomalies are unrelated to this device).
*（Note: Windows XP does not support the driver. Please use Windows 7 or higher systems).
