D3e Bluetooth DAC Dual PCM1794A USB Interface Femtosecond Crystal Oscillator

Description: Description D3e Bluetooth DAC Dual PCM1794A USB Audio Interface Femtosecond Crystal Oscillator for LDAC AptX-HD D3e Version: - Chip: Dual PCM1794A - Bluetooth: 5.1 (QCC5125) - USB: interface for Amanero (Femtosecond crystal oscillator) - Op amp: OPA2604AP x 3 Material List: - Components for Nichicon - Dual PCM1794A - Pluggable op amp - Components for WIMA - Removable USB card - QCC5125 Bluetooth - Components for Nover Attention: - Electronic components are subject to periodic changes and will be replaced with components of the same quality. - The picture is for reference only, the electronic components will change without notice. Please refer to the actual product. Thank you for your understanding! Features: - Remote control functions: it enables wireless playback from speakers without Bluetooth. Old-fashioned power amplifiers can also get rid of the shackles of cables and make digital music resources richer (remote control functions: can switch the machine on and off, mute, switch input) - Bluetooth wireless input: Adopt the latest QCC5125 Bluetooth lossless solution. Support encoding formats for LDAC, aptX-HD, AAC. Supports 24bit 96kHz audio CD-level sound quality. Good sound quality, without delay. Reduce the secondary loss of sound quality compression, accurately reproduce the full audio bandwidth, HIFI-level high fidelity - PCM1794A chip: It has high sampling rate and resolution. Its sense of speed and transparency is very good, and the three-frequency sound is very commendable, especially the mellow and sweet vocals. This is a very cost-effective chip - Screen display: Using a 1.2-inch IPS display, it can display the signal channel being input and the real-time sampling rate. Large viewing angle display allows users to master audio information from a distance - Signal receiving: Adopt CT7302 receiver scheme PCM 32BIT/384KHZ, let PCM1794A support input DSD and DOP. The CT7302 is a lower jitter S/PDIF receiver than the AK4118. High sampling rate: advanced digital input processing chip CT7302, input channel with power-down memory, low jitter, high sampling rate - MCU software control: The performance of PCM1794A is optimized by software control of single chip microcontroller solution. Power on/off through the panel buttons. The input signal is automatically recognized. Using broken sound elimination technology, it can solve the broken sound generated when the song is switched, fast forwarded, and the sampling rate is changed. - Filter op amp: Adopt active LPF, and I/V conversion design. Compared with other passive resistance-capacitance structures, it is more conducive to improving the system's response speed to audio, making the signal distortion lower and the music dynamic more rapid and powerful - 3pcs dual op amp: reserved IC seat, through simple plug and play, you can replace the op amp of different music styles - High-quality power supply: Built-in true dual-source positive and negative voltage conversion design. Compared with other capacitor voltage divider structures, it is more conducive to improving the symmetry of positive and negative voltages, making the Bluetooth signal for LDAC more stable, and making the PCM1794A decoding smoother - Secondary voltage regulation: High-performance power purification circuit design reduces ripple interference caused by switching power supply, and provides clean power for DAC and LPF - Support a variety of input sources and switching is more convenient Specifications: - Dimensions: 120 x 95 x 30mm (LxWxT) - Weight: 283g - External power supply: 12V DC (jack 5.5-2.1) - Input Interface: Bluetooth 5.1 (QCC5125); Coaxial; Optical; USB - Output interface: RCA (output level 2Vrms) - Sampling rate: 16-32Bit 44.1-384kHz - Power consumption: 0.58W (standby <0.1W) - Bluetooth Specifications: For LDAC, aptX-HD, aptx, SBC, AAC (mobile phones need to support functions for LDAC and APTX) Package Included: - 1 x Main unit - 1 x 12V power adapter - 1 x Bluetooth antenna - 1 x Remote control - 1 x Product quality certificate Note: - Battery for the remote control is not included.
