Standard Version CMD27 MKII Dual CS43198 Balanced Remote Control Audio Decoder Bluetooth Headphone Amplifier

Standard Version CMD27 MKII Dual CS43198 Balanced Remote Control Audio Decoder Bluetooth Headphone Amplifier

Features:
- It used Italian sub card, which is pluggable.
- Support DSD512 play, and the USB is equipped with electrical isolation to prevent the interference of computer power supply and ground wire to DAC.
- Dual 25W sealed digital analog power supply, 4-way independent voltage stabilization, 8 groups of LD0 secondary voltage stabilization, low heating and low ripple.
- Wafer resistor and film capacitor are used in the simulation part.
- Full size 430mm wide aluminum chassis.
- Dual 6120 chip balanced headphone amplifier, 4.4 XLR + 6.35 + 4-core XLR output.
- The level LED meter is added. (The impact on sound can be ignored.)
- Both coaxial and RCA outputs are pure copper gold-plated terminals.
- Chip capacitors are for Panasonic FC, FK and for Nikon gold letters.
- 2.42inch screen
- Equipped with 4 large capacity filter capacitors.
- It is equipped with standard discrete Class A operational amplifier module, which has a large working current, a better listening feeling and better dynamic performance than many high-quality operational amplifiers.
- The upgrade version has higher decoding power and more vacant sound, but the standard version is more suitable for pop music.

Package Included:
- 1 x Host
- 1 x Power cable
- 1 x USB data cable
- 1 x Bluetooth antenna
- 1 x Remote control

Note:
- The Bluetooth antenna can be installed on the antenna base without tightening it, otherwise it may drive the wires inside the base to rotate, resulting in disconnection and failure to find the Bluetooth.
- If it is found that the Bluetooth device cannot be paired, please turn off the DAC for 1 minute and then turn it on to pair again.
- When FOOBAR is playing, it will occupy the for Amanero device exclusively. At this time, other software is not allowed to make sound. To use other software, you can only stop or close FOOABR, and set for Amanero as the default device. (Exclusive ownership can also be canceled in the for Amanero attribute)
- Only mono is available for Bluetooth playback. In this case, the LHDC function (seashell player) is generally turned on. Since our Bluetooth supports LDAC, and does not support LHDC, there will be conflicts. Therefore, turning off the LHDC function can be normal.
- When the volume is lower than 50, the LED level meter may not indicate. (Only 2 lights are on)
- Pay attention to the protective film on the surface of plexiglass, which is not scratched, and do not misunderstand.

FAQ:
Q: The machine will heat up after several hours of use.
A: Since three Class A operational amplifier modules and dual TPA6120 earphones are used in the device, heating is a normal phenomenon.

Q: The LED level meter does not jump.
A: Please press the LED level meter switch on the back and turn the volume to more than 50 (the volume of the front-end device connected to the decoder must be turned to the maximum).

Q: Does the volume control of the decoder affect the sound?
A: This machine adopts MCU chip to control the sound output amplitude inside CS43198, which is digital volume control and non-traditional volume. So it will not affect the sound.

Q: Why do you often hear the clattering sound inside the aircraft?
A: There is a mute relay in the machine. When there is no signal from the coaxial, optical fiber and Bluetooth, it will automatically disconnect and automatically connect when there is a signal, so it is normal to have a clicking sound.

Q: If the earphone is plugged in, does the back output still have sound?
A: Yes. All interfaces output at the same time. Plugging in headphones will not affect the back output.
