Heareal J4 Bluetooth5.4 HiFi Audio Player DSD Digital Broadcasting 2x9038Q2M DAC Headphone Amplifier
Description:
- For Qualcomm QCC3084 Bluetooth 5.4 chip, supports for LDAC/aptx-HD protocol, 24bit/96kHz bitrate transmission.
- USB playback: supports 512 folders and up to 99999 music files for storage and playback. The USB or portable hard drive format is EXFAT or FAT32, and supports up to 2T portable hard drives.
- TFT full-color display screen: input status, signal format, volume level, playback status, file information display are intuitive, and the operation is clear.
- Multi functional remote control, simple and convenient.
- Dual channel separation circuit architecture: independent low-pass filtering and independent amplification for left and right channels, equipped with two classic high frequency operational amplifiers OPA2134, with a bandwidth of 8MHz, capable of clear performance in high, medium, and low frequencies, and ultra-low distortion.
- For ELNA HiFi audio filtering capacitor is selected, with ripple as low as microvolts, rejecting power circuit interference, and a quiet background.
- 6.35mm headphone port, built-in headphone amplifier architecture circuit for Lahmann, better elasticity in the mid to low frequency range, meticulous and durable. Independent third 2134 operational amplifier (same as original configuration for Lahmann)
- Chip management, high-end power supply. CCC/UL/FCC quality certification, shock surge protection, 90-264V wide width design, stable output, and abundant kinetic energy.
- Adopting gold-plated dual RCA and coaxial ports, low impedance and high conductivity, reducing transmission loss and resistant to plugging and unplugging.
