Black CMD32 DAC 4-Core CS4308P HiFi VU Meter Balanced Decoder Built-in USB Card for XU316 with 4.8-inch LCD

Black CMD32 DAC 4-Core CS4308P HiFi VU Meter Balanced Decoder Built-in USB Card for XU316 with 4.8-inch LCD

Precaution:
- When the decoder is connected to other devices such as headphone amplifiers or power amplifiers, the volume of the decoder is adjusted to 100, and the back-end device is used to control the volume to achieve maximum dynamic effects. (Note: Some devices may experience sound distortion at maximum volume, so the volume should be reduced)
- The default shipment for AMANERO sound card firmware supports playing DSD512 on WIN system. If you need to support for DAPHILE system, please specify in advance (note: the two systems are not completely compatible); for XMOS 316 supports both systems.
- This device is a pure DAC with no headphone amplifier.
- The HDMI-compatible port is not a video port and can only connect to IIS inputs for digital broadcasting or digital interfaces. Due to the lack of a unified standard for the IIS interface, it may not be compatible with all IIS signals, resulting in phenomena such as silence and noise, which are not considered quality issues.
- Due to the use of imported materials for most parts of the machine, it is often out of stock due to the international situation. Therefore, any changes in materials or design will not be notified separately.

Description:
- CMD32 adopts 4pcs eight channel current type DAC chips CS4308P for Cirrus Logic, with two MONO parallel modes used for each channel, which means that every 16 channels are connected in parallel as one channel output. It is equipped with two newly designed phase noise purification technology clock + CPLD digital buffer shaping, jitter suppression and elimination, clock recovery and regeneration circuits. The sound performance of this product inherits the neutral, transparent and accurate sound characteristics for Cirrus Logic, with excellent dynamic and wide natural sound field, full low-frequency power, good high-frequency extension, rich and bright details without harshness.
- 2 chips per channel: CS4308P works independently, each chip has Super Low Noise LDO independent voltage stabilization and filtering, using for RIFA thin film capacitors.

Features:
- Four 8-channel CS4308P decoding chips, with 2 parallel outputs per channel.
- Six sets of inputs (coaxial, fiber optic, Bluetooth, IIS*2, USB), pure decoding without headphone amplifier.
- Output interface: XLR balanced, RCA single ended, subwoofer SUB
- Optional for Amanero USB card or XMOS 316 USB card powered by LT3042 or 3045.
- Standard configuration includes 2 sealed transformers for Talema, with independent power supply for both digital and analog channels.
- There are a total of 13 operational amplifiers, of which 8 are interchangeable designs (4 IV + 4 LPF)
- The output volume can be adjusted, or bypass (with the volume adjustment function turned off).
- Newly designed 2 clock phase noise purification technologies + CPLD digital buffer shaping, jitter suppression and elimination, clock recovery and regeneration circuits.
- Up to 16 sets of independent voltage stabilization circuits, using for TI's latest ultra-low noise uV level LDO, with each chip independently stabilizing the voltage.
- Five button design, convenient and fast (some buttons are reusable).
- Full function remote control, 4.8-inch long LCD screen, 6 digital VU meter designs.
- The motherboard adopts a four layer circuit board design, with low noise and low distortion.
- A large number of fever components establish a good sound foundation.
- All aluminum precision chassis of 430 x 230 x 63mm, with no screw design on the top cover.

Bluetooth Connection Instructions:
- Connect the randomly attached Bluetooth antenna (the Bluetooth antenna can be installed on the antenna socket without tightening it, otherwise it may cause the wires inside the base to rotate, resulting in disconnection and inability to receive signals).
- Adjust the input selection until the display screen shows "BT".
- Take your phone as an example, go to "Settings" - "Bluetooth" on your phone, click "Search Device", and you will soon find "QCC3084". Then click "QCC3084" and your phone will automatically pair and connect successfully. In the "Paired Devices" section, "Connected to Media Audio" will be displayed, and you can start playing songs.
- It is recommended to use a phone that supports for ATPX or APTX-HD, LDAC functions, as the sound quality is very good. (There are also significant differences in Bluetooth sound quality among different mobile phones)

Materials:
- For NEC silver-plated contact signal relay for audio conversion.
- For ERO, Philips HiFi film capacitors.
- 8 high-performance high current operational amplifiers, balancing low distortion and flavor, high signal-to-noise ratio, and excellent dynamic performance. All 8 op amps are equipped with sockets, and users can also adjust the style themselves.
- Two audio specific crystal oscillators with built-in independent voltage stabilization and phase noise processing circuits, with phase noise lower than -165dBec at 1KHz. Better than common oven-controlled crystal oscillators.
- Two blue imported sealed transformers for Talema provide separate power supply for digital and analog circuits, providing pure sound quality and reducing digital odor.
- QCC3084 Bluetooth module, supports for LDAC, APTX-HD and other high-definition modes, Bluetooth 5.4 protocol.
- Optional for Amanero USB interface/XU316 interface.
- Silver plated signal cable, gold-plated RCA socket.
- Four layer circuit board design, neat and reasonable layout, sufficient materials for power filtering.
- Complete interfaces and strong adaptability, with 2 IIS input interfaces and 1 subwoofer output interface.

FAQ:
- The Bluetooth antenna can be installed on the antenna base without tightening it, otherwise it may cause the wires inside the base to rotate and break, making it impossible to search for Bluetooth.
- If you find that the Bluetooth device cannot be paired, please turn off this DAC for 1 minute and then turn it on again to re pair.
- When playing FOOBAR, it will exclusively occupy the device for AMANERO, and other software is not allowed to produce sound. To use other software, FOOBAR can only be stopped or turned off, and AMANERO will be set as the default device. (You can also cancel exclusivity in the AMANERO attribute).
- Only mono is available during Bluetooth playback. This situation is usually caused by turning on the LHDC function (as this Bluetooth supports for LDAC and does not support for LHDC, there may be conflicts, so the LHDC function should be turned off).
- Note that there is a protective film on the surface of the organic glass, which is not scratched. After confirming receipt, tear it off.
