CMD27 Dual CS43198 Balanced DAC DSD512 Bluetooth Audio Decoder 30PCS Audio Capacitor for ELNA with VU Level Meter

CMD27 Dual CS43198 Balanced DAC DSD512 Bluetooth Audio Decoder 30PCS Audio Capacitor for ELNA with VU Level Meter

Features:
- Dual CS43198 chips, one independent mono working mode per channel, true balance design, instead of most products using operational amplifiers to switch from single ended to balanced.
- 430mm all aluminum CNC machining chassis, large desktop computer, stylish and durable.
- Standard configuration includes USB sub card for Italian Amanero, supports DSD512 hard release mode, and supports for daphil, WIN, and MAC systems. Equipped with electrical isolation to prevent interference from the computer's ground wire to the DAC, which may cause a decrease in listening experience.
- Two 25W sealed ring transformer digital analog are independently powered, and the analog operational amplifier uses a super linear voltage regulator circuit, with high output current and low noise. The digital part consists of 8 sets of low-noise LD0 independent voltage regulators for each chip.
- Dual TPA6120 balanced headphone amplifier, with a maximum output power of 2W and no background noise.
- Equipped with our self-developed Class A operational amplifier module as standard, the distortion and listening experience are better than most operational amplifiers.
- By using high-end gold capacitors for Panasonic, Nichicon and others, for VISHAY wafer resistors, WIMA, ERO film capacitors, and excellent circuit design, the best performance of 43198 can be achieved. The distortion is as low as 0.0001%.
- 2.42-inch OLED display screen, fully functional remote control.
- Digital control volume, which can control the sound of each output port without popping sound.
- Specially designed volume level LED indicator allows you to observe the sound output status at any time (there will be no indication if the volume is below 50, and it can also be turned off), and it will hardly affect the sound.

Precaution:
- 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 back on to re pair.
- When FOOBAR plays, it will exclusively occupy the device for Amanero, and other software is not allowed to make sound. To use other software, FOOABR 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 (for Hiby Player), as this Bluetooth supports for LDAC and does not support for LHDC, there may be conflicts. Therefore, turning off the LHDC function can restore normal operation.
- When the volume is below 50, the LED level meter may not indicate. (Only 2 lights on)
- Note that there is a protective film on the surface of the organic glass, not scratches, do not misunderstand.

Package Included:
- 1 x Audio Decoder

FAQ:
1. The machine will heat up after a few hours of use.
- Due to the use of three Class A operational amplifier modules and dual TPA6120 headphone amplifier chips inside the machine, heating is a normal phenomenon.

2. The LED level meter does not jump.
- Please press the LED level switch on the back and increase the volume to greater than 50 (the volume of the front-end device connected to the decoder must be adjusted to the maximum state).

3. Does the volume control of the decoder affect the sound?
- This machine uses MCU chip to control the sound output amplitude inside CS43198, which is a digital volume control and not a traditional volume control, so it will not affect the sound.

4. Why do you often hear the dada sound inside the machine?
- The machine is equipped with a silent relay, which automatically disconnects when there is no signal from coaxial, fiber optic, or Bluetooth, and automatically connects when there is a signal. Therefore, the dada sound is a normal phenomenon.

5. Plug in the headphones, is there still sound from the output behind?
- There is sound, and all interfaces output simultaneously. Inserting headphones will not affect the output behind.
