(Andy 5 étoiles) AkLIAM PD5 AK4493SEQ DAC/ampli USB portable, sortie casque symétrique 4,4 mm et sortie casque 3,5 mm, PCM 768 kHz, DSD 512

Must be clear before purchasing: ▶ The AK4493SEQ chip generates a significant amount of heat during operation, so it is normal for the PD5 to feel a bit warm to the touch. ▶ This product is an audio usb DAC headphone Dac&Amp and has no microphone function,so headphone mic cannot be used. ▶ When PD5 is close to the phone and there is a call/text message, the earphones will emit electromagnetic interference noise. This phenomenon is normal, and it will return to normal after the call/text message ends. ▶ PD5 has a relatively high power consumption (normal operating current is 100mA to 200mA). Due to the power output limitations of iOS devices, there will be abnormal sound if the threshold is exceeded for some high impedance headphones/iems.Therefore, we DO NOT recommend using iOS devices for PD5. ▶ Starting from April 2025, the panel at the bottom of PD5 has been replaced with tempered glass. ▶ Please avoid inserting both 4.4mm and 3.5mm earphones at the same time, as it may damage the PD5. ▶ Please feel free to contact us if you have any doubt or need help. About External Power Cable EC02 / EC03: ▶ The interference and noise caused by the internal baseband and RF operation of the mobile phone are likely to be transmitted to the USB DAC/AMP through power supply, so the mobile phone is not an ideal power supply for audio Dac&Amp. When using this cable, the current between the phone and the USB Dac/Amp is zero, and the power is directly introduced into the Dac/Amp from the outside power supply without passing through the phone. ▶ Mobile phone output has limitations, especially for Apple devices or some high energy consuming Dac&Amp, using EC02/EC03 can perfectly avoid power supply problems. The phone is only used for data transmission and no longer for power supply tasks.Please click on the image below if you need to purchase separately.
