Portable Balanced Headphone Amp 5.0APTX Independent Decoding Bluetooth Receiver product description 1: Dual earphone design In order to facilitate the use of balanced headset players, the DT3 balanced version is equipped with a 3.5mm single-ended interface and a 2.5mm fully balanced interface. Both interfaces have their own insertion detection function, and the balanced output automatically When the balanced boost function is activated, the output power is increased by about 40% compared with the single-ended output. (Note: When connecting 2.5mm balanced headphones, please turn down the volume of the audio source first) 2: DT3 Balanced Edition The balanced version adopts Qualcomm's full range of QCC3003 Bluetooth 5.0 chips, which is a highly integrated and powerful Bluetooth module, which integrates ultra-low power DSP and application processor, high-performance stereo codec, power management subsystem and LED driver, Support SBC, ACC audio decoding. 3: The balanced version of DT3 adopts dual-channel amp chip + dual-channel independent LDO low-dropout voltage regulator to create a true Fully balanced circuit, introducing the concept of balance in the professional HIFI field into the amp circuit Sound quality provides an overall boost. 4: DT3 high impedance version, dual earphone design The DT3 high-impedance version is equipped with two 3.5mm single-ended interfaces, which can be connected to two headphones at the same time. The built-in voltage is ±7.6V. Two pairs of triode discrete circuits are used, and the output power is up to 250mW. promote. 5: DT3 high impedance version British CSR company CSR8675, Bluetooth 5.0 chip The new product of the British CSR company, the current first-class Bluetooth chip supports various lossless transmission formats such as APTX-HD. Comparing to the smooth experience of line connection, it realizes the same sound quality expression as the line connection with the transmission frequency of up to 24bit/96KHz. 6: Built-in ESS9018K2M decoding chip, the effect of independent high-quality decoding chip is quite different, and the powerful detail reduction ability of ESS chip can easily achieve the purpose of lossless. 7: Built-in triode discrete circuit, 250MW music power output. 8: The DT3 design not only satisfies the coolness of listening to earplugs, but also pushes 300Ω headphones well. Therefore, a driving voltage of ±7.6V is used internally with a thrust of 25MW at 250Ω impedance, which ensures the effect of large headphones. 9: Due to the use of positive and negative power supplies, the entire circuit does not have a coupling capacitor, and the sound transmission from Bluetooth to the amp adopts DC transmission, which will have much less post-adding taste than many competing products using DC blocking capacitors on the market, and the sound is transparent. exquisite.
